PY - 2012/05//Final Report
SP - 46p
AB - Airport sponsors who accept federal funding are obligated to make the aircraft facility available to all aeronautical activities, including parachuting and skydiving. Due to the lack of guidance concerning parachute landing areas (PLA) for airports that are able to accommodate nontraditional aeronautical activities (such as skydiving), research was conducted to determine the recommended size and location of PLAs on airports and provide guidance material. To do this, transition data were collected from airports currently supporting parachute operations, and international and military standards were examined. Site visits were conducted and subject matter experts were consulted. It was determined that the experience of the parachutist and type of parachute used should be considered in developing the size of the PLA. It was also determined that the edge of the PLA should be located no closer than 40 feet from a hazard. In addition, the report includes recommendations for operational procedures and practices.

TI - Evaluation of New Obstruction Lighting Techniques to Reduce Avian Fatalities
PY - 2012/05//Technical Note
SP - 64p
AB - Wildlife biologists have conducted extensive research to better understand how migratory birds are negatively affected by obstruction lights, which are used at night to warn pilots that they are approaching an obstruction hazard. The research concluded that migratory birds appear to be attracted to the steady-burning (i.e., nonflashing) obstruction lights on communication towers and, as a result, thousands of birds are killed annually through collisions with these obstructions. Wildlife organizations, the telecommunication industry, and the Federal Communication Commission collectively approached the Federal Aviation Administration (FAA) and requested that the FAA consider redefining their standards for obstruction lighting to either omit or flash the normally steady-burning red lights to reduce their impact on the mortality rates of migratory birds. In the research reported here, the FAA Airport Technology Research and Development Team evaluated the proposal to omit or flash the normally steady-burning red lights. In addition, researchers evaluated the potential benefit of using light-emitting diode obstruction lights instead of conventional incandescent obstruction lights as a way to mitigate their impact on birds, due to their unique color and flash pattern. A series of flight evaluations was conducted to compare the obstruction lighting on several communication towers in the northern Michigan area. A tower that was equipped with a nonstandard lighting configuration in which the steady-burning red lights were programmed to flash in unison with the red flashing lights was also included in the flight evaluation. The results showed that flashing the steady-burning lights was acceptable for small towers (151 to 350 feet in height) and that they could be omitted on taller towers (over 351 feet) so long as the remaining brighter, flashing lights were operational. The optimal flash rate for the brighter lights to flash simultaneously was determined to be between 27 and 33 flashes per minute (fpm). Flashing at slower speeds (under 27 fpm) did not provide the necessary conspicuity for pilots to clearly acquire the obstruction at night without the steady-burning lights, and flashing at faster speeds (over 33 fpm), the lights were not off long enough to be less of an attractant to migratory birds. Based on the results of this research, the FAA proposes to make specific changes to the obstruction lighting standards, including a proposal to omit or flash steady-burning red lights from several obstruction lighting configurations.

TI - Dallas/Fort Worth Field Demonstration No. 2 (DFW)-2 Final Report for Tower Flight Data Manager (TFDM)
PY - 2012/05//Final Report
SP - 353p
AB - The Tower Flight Data Manager (TFDM) is the next generation air traffic control tower (ATCT) information system. It integrates surveillance, flight data, and other sources, enabling advanced decision support tools (DSTs) to improve departure and arrival efficiency and reduce fuel burn at the airport. During a two-week demonstration in the spring of 2011, TFDM was exercised as a prototype installed at the Dallas / Fort Worth International Airport (DFW). MIT Lincoln Laboratory conducted this demonstration (termed DFW-2) for the FAA in coordination with DFW air traffic control (ATC) and the DFW airport authority. The objective of this TFDM field demonstration was to validate the operational suitability and refine production system requirements of the Tower Information Display System (TIDS) surface surveillance display and Flight Data Manager (FDM) electronic flight data display and to evaluate the first iteration of the Supervisor Display and DSTs. These objectives were met during the two-week field demonstration. Results indicated that the TIDS and FDM exhibited capabilities considered operationally suitable for the tower as an advisory system and as a primary means for control given surface surveillance that is approved for operational use. Human factors data indicated that TIDS and FDM could be beneficial. The prototype Supervisor Display and DSTs met a majority of the technical performance criteria, but fewer than half of the human factors success criteria were met.

TI - General Aviation Airports: A National Asset
PY - 2012/05
SP - 34p
AB - In cooperation with the greater aviation community, the Federal Aviation Administration (FAA) conducted this 18-month review of 2,952 general aviation airports (for the purpose of this report, these landing facilities include mostly airports, but also some heliports and seaplane bases). The report documents many important aeronautical functions that are economically and effectively supported at these general aviation airports. These range from emergency preparedness and response to the direct transportation of people and freight and commercial applications such as agricultural spraying, aerial surveying, and energy exploration. The authors divided the general aviation airports into four categories based on existing activity measures such as the number and types of based aircraft (i.e., aircraft that are stored at an airport), as well as the volume and types of flights. The four new categories are national, regional, local, and basic. Future development of general aviation airports included in the National Plan of Integrated Airport Systems (NPIAS) will continue to be based on eligible and justified needs and priorities, with these new categories providing a more consistent framework within which to evaluate proposed projects. Future NPIAS reports, starting with the FY 2013-2017 report to be issued later this year, will incorporate the new categories developed in this report. The report also raised some important investment and regulatory questions that require further investigation, including: whether current or amended part 139 regulations (i.e., the FAA airport operating certificates) should be extended to the higher-activity general aviation airports; how facility requirements should vary among airports in the new general aviation categories; how Airport Improvement Program (AIP) funds can be used most effectively; and whether all general aviation airports be held to the same grant assurances as other airports.

PY - 2012/04/26
SP - 14p
AB - The Next Generation Air Transportation System (NextGen) Environmental Management System (EMS) Framework and Collaboration Pilot Study aims to foster collaboration between the Federal Aviation Administration (FAA) and aviation’s principal stakeholders (e.g., Air Carriers, Airports, Manufacturers, Local Community). It aims to further define their role in NextGen EMS Framework and Collaboration and identify opportunities to address environmental challenges. The objective of this pilot study is to evaluate which environmental issues have the potential to constrain the mobility of the aviation system and the possible effects of future technology and operational changes. Pilot study information is used to develop NextGen EMS Framework and Collaboration approaches and tools that will help stakeholders identify strategic environmental issues, address these issues, and track improvements. The Denver International Airport (DEN) Master Plan Update Studies Phase II Baseline Activity Projections report was used for the operational forecast for this study. For the DEN Pilot Study, 2010 was chosen as the base year. Through a 10-step technical approach, data were collected and analyzed to establish baselines for air quality, climate, energy, and noise. Using forecast data, and assuming no NextGen technologies and operations were incorporated, future scenarios were then calculated for each aspect to identify environmental issues that could constrain NextGen implementation. Next, several new technology and operational concepts were evaluated to determine those that could mitigate the environmental impacts.

TI - A Technical Review of Methodologies for Calculating Firefighting Agent Quantities Needed to Combat Aircraft Crash Fires
PY - 2012/04//Final Report
SP - 168p
AB - The current method for determining required firefighting agent quantities at an airport is based on the concept of a “critical area” rectangular box defined by the aircraft length and fuselage width. Aircraft size and construction materials have evolved to an extent that the concepts of critical area, which consists of Theoretical Critical Area and Practical Critical Area need to be studied to ensure they are still valid methodologies for determining the firefighting agent requirements for airports. This analysis addressed various factors in assessing current aircraft rescue and firefighting (ARFF) agent requirements. These factors included the historical development of the existing methods and the recent fire-related loss history. The recent loss history includes the effectiveness of the ARFF response and a fire hazard analysis for threats to occupants in an aircraft and those who have escaped the aircraft. The National Fire Protection Association 403 methodology was found to be acceptable and appropriate for establishing agent quantities.

TI - Tower Flight Data Manager Benefits Assessment: Initial Investment Decision Final Report
PY - 2012/03/09/Version 1.1
SP - 116p
AB - The Tower Flight Data Manager (TFDM) is an advanced tower automation system being developed to meet the Federal Aviation Administration (FAA) Next Generation Air Transportation System (NextGen) objectives. The TFDM system provides controllers with advanced surveillance and flight data management display systems that will allow them to maintain an integrated picture of the current situation. Controllers and supervisors will also be provided with a suite of Decision Support Tools (DSTs) that provide critical information for assistance in tactical and strategic decision-making. In addition, TFDM will facilitate data exchange between controllers within a tower facility, between Air Traffic Control facilities, and between stakeholders. The capabilities provided by the TFDM system should enable multiple system benefits, such as reduced surface delay, taxi time, and fuel burn (with associated improved operational and environmental performance); better performance during severe weather and other off-nominal conditions; improved usability and situational awareness; and enhanced safety. This document summarizes the analysis efforts undertaken by Massachusetts Institute of Technology Lincoln Laboratory to estimate the benefits from the key TFDM capabilities over the 2015-2035 timeframe in support of the Initial Investment Decision (IID) benefits assessment process.

PY - 2012/03//Final Report
SP - 41p
AB - In 2008, the Federal Aviation Administration (FAA) Airport Technology Research and Development Team conducted a performance assessment of the iFerret™, electro-optical, foreign object debris (FOD) detection system. This assessment included the system’s capability to detect objects of various shapes, sizes, and materials at all locations on the runway surface. The system’s capability to detect FOD during both nighttime and daytime conditions, in periods of sun, rain, mist, fog, and snow was also assessed. A comprehensive performance assessment of the technology was demonstrated at the Chicago O’Hare International Airport (ORD). Installation of iFerret sensors was completed at ORD in late 2008, and extensive data collection was conducted from June 2009 through July 2010. These were supplemented by an assessment of an iFerret installation at Singapore’s Changi International Airport in May 2009. At the conclusion of the data collection process, the FAA had sufficient data to conclude the performance assessment. The iFerret FOD detection system was able to detect objects of various shapes, sizes, and materials on runway surfaces, taxiways, and aprons and was able to perform satisfactorily in nighttime, daytime, sun, rain, mist, fog, and snow conditions, as required by FAA Advisory Circular 150/5220-24, “Airport Foreign Object Debris (FOD) Detection Equipment.”

TI - Freighter Airplane Cargo Fire Risk and Benefit Cost Model
PY - 2012/03//Final Report
SP - 73p
AB - The Federal Aviation Administration (FAA), Transport Canada, and the United Kingdom Civil Aviation Authority requested a Risk and Benefit Cost Model be developed to assess the likely number of U.S.-registered freighter fire accidents, and the benefit/cost ratio associated with seven mitigation strategies identified by the FAA. This report explains the data used by the Model, its algorithms, and the way in which the Model may be used. The Model addresses the potential fire threat from all forms of cargo, including the bulk shipment of lithium batteries (primary and secondary) because they likely contributed to two of the five freighter fire accidents that have occurred on U.S.-registered airplanes. The Model displays the number of accidents through 2020 and costs, benefits, and the benefit/cost ratios through to 2025. The Model prediction of the average number of accidents likely to occur from 2011 to 2020, if no mitigation action is taken, is approximately 6—with a 95-percentile range of approximately 2 to 13. If no mitigation action is taken, accident costs are likely to average approximately $44 million (U.S.) per annum over the period 2011 to 2025. The primary contribution to freighter fire accident costs is the value of the airplane—with values of approximately 90% of the total accident cost for the larger freighter airplanes. However, the Model predictions of accident costs are based on the assumption that the composition of the U.S.-registered freighter fleet will be largely unchanged from 2010 through 2025 in terms of the size and value of airplanes. The costs of implementing the proposed mitigation strategies are currently not known to a sufficient level of accuracy to make accurate determinations of benefit/cost ratios. However, the Model has been constructed to allow user inputs of costs once they become available.

PY - 2012/03
SP - 116p
AB - The San Diego International Airport (FAA three-letter identifier code “SAN”) is located in the northwest portion of the downtown area of San Diego, California. The airport is bounded by North Harbor Drive and San Diego Bay to the south, the Navy water channel and Liberty Station to the west, the Marine Corps Recruit Depot to the north, and Pacific Highway and Interstate 5 to the east. The airport is operated by the San Diego County Regional Airport Authority (SDCRAA). At 661 acres, SAN is one of the smallest major airport sites in the U.S. The airport has a single 9,401-foot-long, 200-foot-wide runway running east-west, and is the busiest single runway commercial airport in the nation. A visual guidance lighting system is an important safety feature at many airports. The term “visual guidance lighting system” is used to identify, as a type of facility, those configurations of lights located on and in the vicinity of an airfield providing pilots with a visual reference for guidance purposes while operating an aircraft during an approach for landing. These facilities are vital visual aids to the pilot and may be used with or without electronic landing aids, such as an Instrument Landing System (ILS). An approach lighting system (ALS) is a configuration of signal lights disposed symmetrically about the extended runway centerline, starting at the landing threshold and extending outward into the approach zone. This system provides pilots with visual information regarding runway alignment, height perception, roll guidance and horizon references. The ALS at SAN is a Medium Intensity Approach Lighting System with Runway Alignment Indicator Lights (MALSR). This report describes the lighting system at SAN.

TI - An Investigation of Sensory Information, Levels of Automation, and Piloting Experience on Unmanned Aircraft Pilot Performance
PY - 2012/03//Final Report
SP - 24p
AB - The current experiment was intended to examine the effect of sensory information on pilot reactions to system failures within a UAS control station simulation. This research also investigated the level of automation used in controlling the aircraft and the level of manned flight experience of the participants, since these also have been shown to influence pilot effectiveness. While the presence of sound did improve responses to engine failures, it did not improve responses to failures in heading control. The prediction that higher levels of automation would lead to complacency or vigilance decrements was not supported. The finding that pilots, in the manual conditions, flew significantly closer to the flight path than non-pilots was unexpected. The results suggest differences between those with manned aircraft experience and those without, but it is unclear whether these differences are due to manned aircraft training and flight experience or whether other factors, such as personality, may be evident.

TI - Legal Aspects of Airport Programs. Topic 04-05. Compilation of DOT and FAA Airport Legal Determinations and Opinion Letters, through December 2011
AB - Virtually all U.S. airports with commercial airline service have accepted federal grants under the Airport Improvement Program (AIP) (Title 49, U.S.C., Chapter 471). In exchange for these grants, airports agree to comply with numerous federal assurances, ranging from requirements that their rates be reasonable to implementation of disadvantaged business enterprise programs. The Federal Aviation Administration (FAA) adjudicates complaints, brought by FAA or raised by third parties, relating to alleged failures by airports to comply with the AIP grant assurances. Prior to 1996 the FAA's procedures for processing and making determination regarding complaints against federally-funded airports were set forth in 14 CFR Part 13, a set of regulations applicable to a variety of adversarial proceedings within FAA's jurisdiction. In 1996, the FAA promulgated Part 16, regulations relating to processing complaints against airports specifically. Part 16 includes several stages of FAA review, and therefore multiple decisions may be issued by the FAA in a particular Part 16 proceeding. It is very difficult for attorneys representing airports to find either the older Part 13 decisions relating to airports, or the more recent Part 16 decisions. In addition, airport attorneys are rarely aware of Department of Transportation (DOT) general counsel opinions or FAA chief counsel opinions on airport legal issues. This project would make these materials available. The subcommittee is aware that the LEXIS™ service contains a library of Part 13 and Part 16 decisions. Many airport attorneys, however, use a different online legal research service and do not have access to LEXIS. In addition, the LEXIS library contains numerous Part 13 decisions that do not relate to airports, and that library, as best as the study can tell, does not include any DOT general counsel decisions or FAA chief counsel decisions. Furthermore, LEXIS does not include a case summary to accompany the text of Part 13 and Part 16 decisions. WESTLAW service contains a similar library, subject to comparable limitations on its usefulness. Part 16 decisions are also maintained on the FAA website. As with other online resources, there is no case summary and no digesting or indexing. Decisions are only searchable by names of party or docket number. Also, DOT general counsel and FAA chief counsel opinions are not available through this on-line source. Airport Cooperative Research Program (ACRP) 11-01, "Legal Aspects of Airport Program" previously published ACRP Legal Research Digest (LRD) 4, Compilation of DOT and FAA Airport Legal Determinations and Opinion Letters Through December 31, 2007, by Spiegel & McDiarmid, August, 2008. That report consists of a bound volume of indexes and a CD-ROM with the same indexes, digested determinations and opinions, and close to 2000 pages of determinations and opinions. The determinations and opinions are numbered in the indexes by document numbers and linked. The objective of this study topic was to supplement and update ACRP LRD 4.

TI - 2010 Aerospace Medical Certification Statistical Handbook
PY - 2012/02//Final Report
SP - 50p
AB - The annual Aerospace Medical Certification Statistical Handbook reports descriptive characteristics of all active U.S. civil aviation airmen and the aviation medical examiners (AMEs) that perform the required medical examinations. This information has not been published since 1998, so in response to recent need, the U.S. Federal Aviation Administration (FAA) reinstated the annual report. The 2010 annual handbook documents the most recent and most widely relevant data on active civil aviation airmen and AMEs. Medical certification records from 2006-2010 were selected from the Document Imaging Workflow System (DIWS) which is the FAA medical certification database. All medical data were abstracted from the most recent medical examinations with the exception of medical conditions which were historical and current. Only those with a non-expired medical certificate remained in the dataset. AME records were selected from the Aviation Medical Examiner Information System (AMEIS). The current status of each AME was determined for each year of the study period from 2008-2010, retaining only those with an active status. Airman variables include age, issued and effective medical classes, height, weight, BMI, gender, select medical conditions, special issuances, and FAA region of residence. AME variables include AME type, age, gender, medical specialty, pilot license status, senior examiner status, and region. As of December 31, 2010, there were 598,642 medically certified airmen age 16 and older, and 30.9%, 22.1%, and 47.0% were issued a Class 1, Class 2, and Class 3 medical certificate, respectively. Across all medical classes, the average age was 44 years and 93.5% of the airmen were male. The mean BMI for both females and males was 24.2 and 27.3 respectively. Six percent of issued certificates required a special issuance. The most commonly reported medical condition was hypertension with medication, at 11%. Of the 3,651 active AMEs, 93% were civilian, 2.4% federal, and 4.6% military. Nearly 50% reported their medical specialty as family practice. Their average age was 59.4 years; the majority (52%) did not hold a pilot license, and 82% were male. In summary, this report contains widely requested data on the active U.S. civil airmen population that has not been readily accessible since 1998. This report will be updated annually and will be used by the aerospace community, including FAA leadership, aerospace researchers, advocacy groups, legislative staff, and the general public.

TI - Analysis of En Route Operational Errors: Probability of Resolution and Time-On-Position
PY - 2012/02//Final Report
SP - 24p
AB - The Federation Administration’s Air Traffic Control Organization Safety Management System (SMS) is designed to prevent the introduction of unacceptable safety risk into the National Airspace System. One of the most important safety metrics used in the Air Traffic Organization’s SMS is the rate and severity of air traffic control operational errors (OEs). While OE rates tell us about the frequency of occurrence, the rates in and of themselves do not provide a direct assessment of safety risk. Two additional metrics are proposed for inclusion in the Air Traffic Organization’s SMS. These include the probability of resolution (POR) index and the time-on-position probability (TOPP) index. Whereas the POR is a measure of OE containment (i.e., resolving a loss of separation before the situation worsens), the TOPP is a measure of the occupational risk of an OE occurring due to traffic exposure. In this report, each metric is mathematically developed and empirically evaluated using archival en route data. In Study 1, the utility of the POR is evaluated based on 1293 OEs extracted from an en route OE research database for the period May 1, 2001 to May 31, 2003. In Study 2, the utility of the TOPP is evaluated based on 1,397,206 time-on-position entries from six en route centers for the 2006 calendar year. The results of both studies are discussed within a SMS framework.

TI - Status Report: Assessment of Compatibility of Planned LightSquared Ancillary Terrestrial Component Transmissions in the 1526-1536 MHZ Band with Certified Aviation GPS Receivers
PY - 2012/01/25
SP - 157p
AB - The Federal Aviation Administration (FAA) has worked with LightSquared since August 2011 to evaluate the compatibility of certified aviation receivers with the planned LightSquared ancillary terrestrial component (ATCt) network using a signal broadcast in the 1526-1536 MHz band. The assessment in this report is based on FAA performance standards. Unlike most other global positioning system (GPS) devices, certified aviation GPS receivers have interference rejection requirements specified by the FAA and harmonized internationally. Aircraft antenna characteristics are also specified. The use of these specifications precludes the need to individually test every aviation device, and allows the assessment to be accomplished through analysis which estimates the LightSquared interference present at the aircraft GPS receiver, and then compares that level to the specified rejection limits. To predict the interference at the aircraft, the FAA has developed a set of propagation models that build upon testing conducted by the mobile satellite services and cellular communications industries for terrestrial applications. Unfortunately, aircraft operate at altitudes where no significant research on propagation has been conducted. Addressing this gap has been the primary focus of the FAA and LightSquared activities though several technical issues remain unresolved, which would require additional resources. While variations in the FAA and LightSquared models affect the scope of impact, they do not affect our fundamental conclusions. Two conclusions can be drawn from the analysis work done to date: (1) The proposed ATCt network is not compatible with FAA requirements for operations dependent on GPS receivers at low altitudes in the vicinity of the ATCt transmitters; and (2) The variations in local propagation environments preclude adoption of any readily-implementable mitigation for this inference.

TI - Enhanced Oversight of Staffing and Training at FAA's Critical Facilities is Needed to Maintain Continuity of Operations
PY - 2012/01/12
SP - 21p
AB - Ensuring that the Federal Aviation Administration's (FAA) most critical facilities are fully staffed with qualified air traffic controllers is vital to maintain the safety of the National Airspace System (NAS). Since fiscal year (FY) 2005, FAA has begun hiring and training over 12,000 new controllers to offset the impending retirements of those hired after the 1981 controller strike. With so many veteran controllers leaving, FAA faces the risk of not having enough certified professional controllers (CPC) to operate its busiest and most complex air traffic control facilities. These include locations such as Southern California, Atlanta, Chicago, and New York, many of which now have newly hired controllers. The Department of Transportation Office of Inspector General (OIG) was asked to review controller training and staffing at FAA's most critical air traffic control facilities to determine if FAA is positioned to ensure the continuity of facility operations. Briefly, it was found that enhanced oversight of staffing and training at FAA's critical facilities is needed to maintain continuity of air traffic operations. Critical facilities face a potential shortage of CPCs as they have higher rates of retirement eligibility, controllers-in-training, and training attrition than the national average. For example, 15 of the 21 critical facilities that OIG reviewed had a higher percentage of their controllers in training than the national average of 25%. Between FY 2008 and FY 2010, critical facilities also lost 40% of their trainees to attrition, compared to the national average of 24%. A contributing factor is that the complexity of the locations makes it more difficult for inexperienced new hires to certify. Yet, FAA's national training program has not provided critical facilities with the training resources they need to help slow staffing shortfalls. As a result, some facility managers have developed their own training programs to supplement lab and classroom training. However, as FAA begins deploying Next Generation Air Transportation System (NextGen) technologies, critical facilities will require even more training resources for both veteran and new controllers. Without a consistent, national approach to address critical facilities' staffing and training needs now, it will be difficult in the short term for FAA to ensure continuity of their operations and, in the long term, effectively transition them to NextGen.

With the implementation of new procedures from the NextGen research, the role of airports will be to accommodate the increased traffic safely. This is especially critical during aircraft operations in inclement weather. This will require development of technologies to heat airport pavements, reliable methods to assess the braking performance of aircraft, development of lighting and marking materials providing higher visibility, development of new lighting technologies, such as, holograms, developing methods to mitigate wildlife at or near the airport, and developing new and efficient techniques for aircraft rescue and fire fighting.

AB - In November 2000, a vertical drop test of a Boeing 737 airplane fuselage section was conducted at the Federal Aviation Administration (FAA) William J. Hughes Technical Center, Atlantic City International Airport, New Jersey. The intent was to determine the impact response of a narrow-body airplane fuselage section, including the response of the airframe structure and cabin items of mass. The purpose of this study was to develop a finite element model to simulate the vertical drop test of that fuselage section. The 10-foot-long test section included 18 seats occupied by dummy passengers, luggage stowed in the cargo compartment beneath the floor, and two different FAA-certified overhead stowage bins. The test article was dropped from a 14-foot height, resulting in a vertical impact velocity of 30 ft/sec. The primary goal of this drop test was to characterize the behavior of the two overhead bins under a severe, but survivable, impact condition.

TI - Perceptions and Efficacy of Flight Operational Quality Assurance (FOQA) Programs Among Small-scale Operators
PY - 2012/01//Final Report
SP - 28p
AB - Despite safety and economic advantages, as well as endorsements by the International Civil Aviation Organization, the FAA, the National Transportation Safety Board, and Congress, voluntary Flight Operational Quality Assurance (FOQA) participation has not been fully implemented in the United States (GAO, 2010), particularly among small operators. Pilots’ concern about data misuse continues to be one of the primary factors preventing participation in voluntary safety programs. Considered in conjunction with pilots’ attitudes and pressure from pilot unions, airlines might find it difficult to justify the cost of implementing and maintaining a FOQA program if they are dubious about its benefits or concerned about its risks. Increased FOQA participation among small-scale air carriers may depend on demonstrating that significant safety benefits can be gained and positive perceptions of the program sustained, with minimal cost to the operator. The current study evaluates both attitudinal and operational aspects of a FOQA program maintained by a small-scale government aircraft operator. The Perceptions of Flight Operations Quality Assurance (PFOQA) questionnaire was used to systematically collect information about pilots’ attitudes regarding FOQA. Questionnaire items were based on concerns and recommendations proposed by the Flight Safety Foundation FOQA task force created to identify issues that might hinder or prevent the implementation of FOQA. Survey participants were a sample of 83 government pilots drawn from a population of approximately 180 Office of Aviation System Standards (AJW) pilots. A time series analysis of FOQA event rates was used to determine whether quarterly reports providing feedback to pilots (a cost-effective intervention method) can produce significant safety benefits. FOQA exceedances used in the time series analyses were de-identified monthly summary data for the Learjet 60 fleet recorded between July 2006 and November 2010. The overlap between the distributions of the Positive and Negative Perceptions scales of the PFOQA suggests that the pilot group demonstrated a certain amount of ambivalence toward FOQA, recognizing both the value and risks of the program. The results of the time series analyses indicated that feedback provided to pilots in quarterly reports produced significant reductions in exceedance rates. A trend in the time series data was the pervasive reduction in these exceedances over the course of the program. This was encouraging for the AJW operation and should motivate other small operators to pursue FOQA.

APT is the controlled application of a prototype wheel loading, at or above the appropriate legal load limit, to a layered pavement system to determine pavement response and document performance as damage accumulates in a compressed time period. A great variety of APT experiments have been executed over the last hundred years. This document is the result of a literature review on the history and evolution ofAPT that was foundational to the success of the first research cycle at the NCAT Pavement Test Track.

To address the problem of costly delays triggered by thunderstorms, Massachusetts Institute of Technology (MIT) Lincoln Laboratory developed a decision support tool that helps air traffic managers determine when to close and reopen departure routes during periods of convective weather. The Route Availability Planning Tool (RAPT) provides current, reliable route-availability information in a user-friendly format. Automated route conditions displayed on a data-rich interface help relieve the decision-making burden typically faced by air traffic managers—gathering weather information, mentally envisioning the repercussions of the weather data, rechecking for rapidly changing weather, and then deciding to allow aircraft to depart.

SN - 9780415621380
PY - 2012
SP - pp 209-214
AB - As part of its Accelerated Pavement Testing (APT) program, the Florida Department of Transportation (FDOT) initiated, in 2001, an experiment to evaluate the effects of polymer modifiers on the rutting performance of Superpave mixes using a Heavy Vehicle Simulator (HVS). That study led to the use of PG 76-22 asphalt binder on the final structural course for traffic level D roadways (10 to >30 million ESALs) and the top two structural courses for traffic level E roadways (≥ 30 million ESALs). As a follow up, a study was conducted to evaluate the performance of stiffer polymer-modified binders meeting PG 82-22 requirements for focused use on intersections and other low speed facilities with concentrated heavy loads. This paper describes the research approach and findings. It is anticipated that the localized use of a PG 82-22 asphalt binder will significantly improve pavement performance at locations with historically excessive rut depths.

SN - 9780415621380
PY - 2012
SP - pp 215-223
AB - Four lanes of pavement test sections were constructed at the Infrastructure System Laboratory (CISL) of Kansas State University. Three of the four lanes had 75-mm geocell-reinforced bases and 25-mm cover of three different in-fill materials; crushed limestone, AB-3; quarry by-products; and Recycled Asphalt Pavement (RAP).The fourth test lanewas the control section consisting of 300-mm crushed stone (AB-3) base.The sections were paved with a 50-mm Superpave Hot-Mix Asphalt (HMA) layer. All sections were instrumented to measure the strains at the bottom of the HMA layer and stresses on top of the subgrade. The sections were loaded with 50,000 and 70,000 repetitions of an 80-kN single axle load of the Accelerated Pavement Testing (APT) machine. The failure rut depth was 12.5 mm. All sections except the control section had this rut depth by 10,000 repetitions. The calculated and measured responses show that on three test sections, stresses on top of the subgrade exceeded the unconfined compressive strength of the soil. The test sections were redesigned and reconstructed. The redesigned sections consisted of 100-mm geocell- reinforced bases, 50-mm cover, and an HMA layer of 100 mm. The same infill materials were used in the test sections. The control lane had a depth of 200 mm. These sections were also instrumented. All sections carried 1,200,000 repetitions of the 80-kN single axle loads with rut depths not exceeding 10 mm. Based on these results, a mechanistic-empirical design methodology for low-volume paved roads with geocell-reinforced bases is being developed.

AB - This paper presents the results of an accelerated pavement testing project conducted by Germany’s Federal Highway Research Institute (BASt). The main objective of the project was to evaluate the long-term structural performance of flexible road pavements under simulated heavy vehicle traffic. For this purpose two test sections of different strengths were subjected to dynamic impulse generator loading to simulate heavy vehicle loading. During loading, the condition of the pavement was monitored by periodic deflection measurements with a Falling Weight Deflectometer (FWD) and measurements of the transverse profile. Embedded sensors provided information on the dynamic mechanical response of the pavement under loading. The results showed a significant increase in the elastic strain at the bottom of the asphalt base course and a decrease in the bearing capacity. Furthermore structural bottom-up cracking in the asphalt base course was detected.A first approach to estimate the vertical propagation of cracks in asphalt pavement layers on the basis of the measured FWD surface deflections is presented.

TI - Evaluation of Trapezoidal-Shaped Runway Grooves
PY - 2012///Technical Note
SP - 66p
AB - The Federal Aviation Administration (FAA) Airport Technology Research and Development Branch initiated research to evaluate a new trapezoidal-shaped pavement groove configuration. The purpose of this evaluation was to determine if the new trapezoidal-shaped pavement groove configuration offered any benefits over the current FAA standard groove configuration, specifically in the areas of water evacuation, rubber contamination, integrity, longevity, and friction values. The new trapezoidal-shaped groove is 1/4 in. deep, 1/2 in. wide at the top, 1/4 in. wide at the bottom, and spaced 2 1/4 in. apart. The current FAA standard groove is 1/4 in. deep, 1/4 in. wide, and spaced 1 1/2 in. apart. Test sections of the new trapezoidal-shaped pavement grooves, along with sections of FAA standard grooves, were installed at the FAA National Airport Pavement Test Facility, the Atlantic City International Airport, Marine Corps Air Facility Quantico, and Chicago O’Hare International Airport. Researchers conducted water evacuation measurements, analysis of rubber contamination, width measurements, and surface friction tests on the trapezoidal-shaped pavement groove test sections under a variety of conditions and compared the results directly to those of the current FAA standard grooves. The results showed that the trapezoidal-shaped pavement groove configuration offered several benefits over the current FAA standard grooves, including improved water evacuation capability, greater resistance to rubber contamination, better integrity, and improved longevity. The friction values for the trapezoidal grooves were comparable to the FAA standard grooves. Analysis of the data collected during this evaluation indicates that the new trapezoidal-shaped pavement groove should be considered an acceptable alternative for pavement grooving on airports.

TI - Accelerated Performance of a Failed Pavement on a Soft Clay Subgrade after Rehabilitation with High Polymer Mix at the NCAT Pavement Test Track
SN - 9780415621380
PY - 2012
SP - pp 203-207
AB - The Pavement Test Track is a full-scale, accelerated performance test facility for flexible pavements managed by the National Center for Asphalt Technology (NCAT) at Auburn University. Forty-six unique 60-m test sections are installed around a 2.7-km oval and subjected to accelerated damage via a fleet of tractors pulling heavy triple trailers. Methods and materials that produce better performance for research sponsors are identified so that future pavements can be constructed based on objective life cycle comparisons. In this study, a 250-mm thick, full depth asphalt pavement that failed near the end of the previous research cycle was first rehabilitated using conventional methods. When the section failed a second time after less than half the traffic that produced the original failure, it was decided to rehabilitate the section again using the same high polymer mix that had performed well in another test section. Traffic applied to the high polymer rehabilitation has now surpassed the level needed to completely fail the original conventional rehabilitation, with no indication that another failure is pending. An overview of the original construction and subsequent rehabilitation of the failed pavement on a soft clay subgrade are included in this paper, with a focus on comparing the performance of the conventional rehabilitation with the high polymer content asphalt inlay.

AB - A flexible test road structure was built and tested in an Accelerated Pavement Test (APT) using a Heavy Vehicle Simulator (HVS) to investigate the performance behavior for validation in a echanistic performance design. The structure was instrumented to measure the responses at different locations due to different wheel loadings and various tire pressures, with single and dual tires. The permanent deformation manifested on the surface as rutting was measured. The responses gained from various tire loads and pressures were analyzed using three approaches; all layers linear-elastic, the base nonlinear and base and subbase nonlinear. The measurements taken after 100,000 load repetitions were compared with the measurements taken in the beginning of the test. Some softening effect was noticed in the asphalt layers and was taken into account in the analysis. The observed accumulation of permanent deformation of the unbound layers was modeled using a three parameter model. Generally good agreement was established between the measured and calculated values.

TI - Exploratory Evaluation of Cracking Performance of a 4.75 mm NMAS Overlay Using Full-Scale Accelerated Loading
SN - 9780415621380
PY - 2012
SP - pp 257-263
AB - State transportation agencies have begun to develop and implement specifications for 4.75mm Nominal Maximum Aggregate Size (NMAS) Superpave mixes with some specifications based on recommendations from a study conducted by the National Center for Asphalt Technology. These mixes restore surface texture and ride quality but also have advantages such as optimal use of available aggregates, accommodation of Reclaimed Asphalt Pavement (RAP), and application as an impermeable, thin preservation treatment. A trial 4.75mm NMAS from Virginia DOT was placed as a thin treatment on existing accelerated pavement test sections. The objectives of this study were to conduct full-scale load testing to gain confidence in a new mix design and to explore the ability of this thin treatment to curtail top down cracking. Several sub-sections, which were reserved and left unloaded from a preceding study, received a 25mmthick mill-and-fill with the 4.75mmNMAS mix. The construction produced a test section where half of the loaded wheel path was paved with the 4.75mm NMAS mix allowing a direct comparison of cracking performance with and without the thin treatment. Full scale accelerated aging was utilized to compare the fatigue cracking performance for four combinations; with and without 4.75mm NMAS treatment each with and without aging. Crack maps illustrated that the unaged 4.75mm mixture’s cracking performance exceeded the life of the sections without the treatment. Estimates of the increase in life provided by this thin treatment exceed 8 years. Forensic coring has shown top-down cracking to be the predominant distress. When aged, however, the 4.75mm treatment provided no additional life, but performed as well as an aged section without the treatment.

TI - Rutting Resistance of Asphalt Pavements with Fine Sand Subgrade under Full-Scale Trafficking at High and Ambient Air Temperature
SN - 9780415621380
PY - 2012
SP - pp 265-276
AB - The rutting performance of an asphalt pavement structure with a fine sand subgrade and a high groundwater table was evaluated with full-scale trafficking tests with the Mobile Load Simulator 66 (MLS66) on Chong-ming Island, Shanghai.The purpose was to establish the reliability of the design with fine sand.There were two test sections with the same asphalt pavement structure but different subgrade depths. Track I was designed with a shallow 1.5m fine sand subgrade and Track II was designed with a medium 3.0m fine sand subgrade. The two tracks were constructed using traditional procedures on the natural clay subgrade covered with a layer of graded macadam. The asphalt pavements consisted of three asphalt layers (total 200 mm) and two cement-treated aggregate layers (total 540 mm, with 5% cement). The top 600mm to 800mm of the subgrade was treated with 3 to 4% cement. Track I was subjected to 1 million load applications at elevated temperature for 15 days and 1.1 million load applications were applied onTrack II at ambient air temperature for 17 days. Profile and temperature data were collected. Pavement profiles and diagnostic excavation indicated that pavement deformation originated from compression and shear flow of the asphalt materials. No fatigue cracking was observed. The influence of the fine sand subgrade and its depth on pavement rutting was negligible. Cores and pit surveys showed that the top asphalt layer of 120mm thickness was significantly affected by trafficked loading and temperature. The rate of rutting and total deformation volume of asphalt at high temperature was 1.5 times that of the test at ambient air ttemperature during early trafficking, about three times more thereafter. The rate of deformation on Track I was almost twice as fast as that ofTrack II. It is concluded that thick asphalt pavement with cement- treated-aggregate base will have good rutting resistance and can be expected to be a perpetual structure.

SN - 9780415621380
PY - 2012
SP - pp 249-255
AB - Various forms of asphalt pavement distress can be attributed, in many cases, to low air voids in mixtures during production and placement.When lowair voids are encountered during production, the specifying agency must decide whether to require the material that has already been placed to be removed and replaced or whether it can be left in place. This study was conducted, in part, in the INDOT/Purdue Accelerated Pavement Testing (APT) Facility to develop a decision-support tool for dealing with such events that is based on projected rutting performance of the pavement system. The responses to repetitive APT wheel passes of test pavements with low air voids in either the surface or intermediate course were measured using a laser based system. The permanent deformation of the top pavement layers is used, in conjunction with simplified mechanistic analysis and engineering judgment, to formulate the desired decision-support tool.

AB - The Mobile Load Simulator (MLS10) is a new type of Accelerated Pavement Testing (APT) equipment recently purchased by Empa, Swiss Federal Laboratories for Materials Science and Technology. This paper summarizes the results of the first calibration tests of the MLS10 in Switzerland. The objective was to evaluate the performance of the machine for testing pavements constructed with local materials under local guidelines. The focus of the study was the structure of the A4 motorway near Zürich. Three pavements were constructed and trafficked with a total of 1.6 million 65 kN load passes over a period of approximately seven months. To access the structural response throughout the loading history, the pavements were instrumented with different sensors. Transverse profiles of the surface were periodically taken. FallingWeight Deflectometer (FWD) and static deflection bowl measurements were taken before, during, and after trafficking to evaluate the structural condition. Finally, pavement samples were obtained from the section and tested in the laboratory. The pavement response was analyzed and validated with a model using the Finite Element Method (FEM). At the end of the tests almost no sign of distress was observed, showing the durability of the pavement.

SP - pp 411-423
AB - Using two case studies, this paper demonstrates the role that controlled accelerated pavement tests can play in the development of performance based laboratory testing procedures. Firstly, the results of an evaluation of the rut-resistant properties of asphalt mixes under accelerated loading using the Accelerated Loading Facility (ALF) conducted between November 1993 and May 1995 are summarized. The performance ranking of the asphalt mixtures is compared to the ranking determined using a dynamic creep laboratory test. The relative rankings of the mixes were different. The laboratory creep test results suggested that the minimum creep slope could rank the relative performance under ALF loading of mixes having the same composition but different binder type but not the relative performance of mixes having different gradings and compositions. The results of the ALF testing correlated better with the results of laboratory wheel-tracking testing. Secondly, a similar deformation trial was conducted on four different spayed seal surfaced, unbound granular pavements between July 2007 and June 2008. The work was undertaken as a means of validating a Repeated Load Triaxial (RLT) test procedure. The RLT test results brought into question the usefulness of the axial permanent strains measured in the test method as these strains did not identify one of the four test materials as being unsuitable for base course due to its low resistance to lateral shoving. By contrast a wheel tracking test, similar to that adopted after the 1990s asphalt work, correlated reasonably well with the ALF results.

TI - Performance of Thin Jointed Concrete Pavements Subjected to Accelerated Traffic Loading at the MnROAD Facility
SN - 9780415621380
PY - 2012
SP - pp 289-297
AB - With the growing trend in shrinking budgets, as well as increased concern for sustainable engineering, there is strong interest in determining how thin jointed concrete pavements can be constructed and still provide predictable long term performance. In 2008, five thin concrete test sections were constructed at the MnROAD pavement test facility toward addressing that question. Design slab thicknesses ranged from 130 to 165mm (5 to 6.5 in.). The sections were constructed on the MnROAD mainline roadway, thus exposing them to accelerated loading in the form of live, high volume interstate traffic. Other than some variations in panel length and dowel type for the thinnest sections, all other design variables were kept constant. This paper summarizes the performance of the test sections after more than two years of traffic and environmental exposure. Several pavement performance parameters were analyzed, including visual distress, joint faulting and load transfer efficiency, panel deflections, and ride quality. Observed performance was also compared to performance predicted by the current Minnesota Department ofTransportation pavement design procedure.Transverse and longitudinal cracking occurred on the thinner sections. Causes for each type of cracking are discussed. While the sections with slabs less than 150mm (6 in.) thick in this study withstood over 1.5 million CESALS before cracking, it is clear the thicker sections have much greater capacity. The data and observations gathered from these cells will benefit the continuing development of mechanistic–empirical design procedures for thin concrete pavements.

To validate this concept, RQI measurements were analyzed for the 22 original asphalt test sections at MnROAD. These pavement test sections were built on the Mainline and Low Volume Road to study their performance under accelerated loading conditions. RQI data was collected twice per year on each section with a Pathways video inspection vehicle, similar to the data collected every year on 12,000 miles of the state highway network in Minnesota. Preventive maintenance treatments were applied at various times to various test sections to repair minor distresses and restore ride quality. This paper discusses the time required for each test section to reach a terminal serviceability level and compares it to the original three, five, or ten-year design life. The paper also considers the ride quality when microsurfacing was applied and the extension in life realized by the maintenance treatment. Finally, the paper examines the distress history within each cell to determine which surface distresses are most responsible for the deterioration in ride quality. The research shows how accelerated pavement testing can be used to validate ride quality concepts used in state pavement management programs. Although no statewide network data is presented in this paper, the MnDOT pavement management program does track the condition of highways over time and is able to quantify the benefits of extended life and reduced costs by applying preventive maintenance treatments.

AB - Increasing use of high productivity road freight vehicles combined with more sophisticated approaches to pavement analysis has led to the need for improved knowledge of the performance of pavement materials. This paper describes the development of laboratory tests intended for routine assessment of strength, modulus and fatigue properties of cemented pavement materials. The laboratory tests involved a four-point bending flexural beam test. Methods for preparation of beam specimens in the laboratory and from field-placed cemented material are described. In order to provide materials performance data needed to verify the improved laboratory tests, the Australian Accelerated Loading Facility (ALF) was used to assess the fatigue performance of two cemented materials. A comparison of laboratory characterization results and full-scale ALF trial results was favorable providing confidence in the use of the laboratory techniques. Two cases involving implementation of the laboratory strength and modulus tests with practical outcomes are presented.

AB - A series of laboratory and full scale Accelerated Pavement Tests (APT) were performed to quantify the effectiveness of geogrid stabilized flexible pavements. The measured responses at critical locations helped to improve understanding of the behavior and benefits associated with incorporation of a geosynthetic within unbound aggregate to form a Mechanically Stabilized Layer (MSL). The information obtained from APT combined with numerical modeling research helped to identify the key features that affect long-term performance of flexible pavements. Further, interpretation of the results generated from this combined approach was used to model the benefits of geogrids in pavement design. This paper presents a general approach to implement APT results in pavement design. This paper will also discuss other types of testing and research that can be used to reliably predict performance prior to establishing a full-scale APT program.

TI - Recommended Asphalt Binder Fatigue Performance Specification from Full-Scale Accelerated Pavement Tests Considering Aging Effects
SN - 9780415621380
PY - 2012
SP - pp 433-441
AB - FHWA has completed a full-scale, accelerated loading experiment to identify an improved performance-based binder purchase specification for fatigue cracking in response to the shortcomings of |G*|sin(δ) in the current Superpave Performance Grading (PG) system. Nine candidate asphalt binder tests relating to fatigue cracking were evaluated and the statistical based selection procedure is described that identified the strongest candidate. A composite score calculated from multiple statistical parameters was utilized to select a test that provides a calculated critical Crack Tip Opening Displacement (CTOD) which evaluates a binder’s strain tolerance in the presence of a crack. This paper summarizes the experimental results and recommendations from the original, principal experiment plus newer data collected from the test sections using full scale accelerated pavement aging. The test sections received an in-situ accelerated aging process, after being in place for more than five years of natural exposure, which heated the test sections to 74 C for eight weeks. The fatigue cracking performance of the aged test sections was measurably decreased when compared to the younger, less aged test sections with little effect on the ranking between material types. The accelerated-aged sections exhibited more top-down cracking than the younger, less aged sections at the same amount of passes. Extracted binder was recovered from the asphalt layers to quantify the variation of aging with depth for modified and unmodified asphalts from both natural aging conditions and the addition of accelerated aging. The relationships between in-situ CTOD in the younger, less aged sections and accelerated aged sections was much stronger than |G*|sin(δ) confirming the original recommendation from the principal experiment.

SN - 9780415621380
PY - 2012
SP - pp 375-385
AB - Over 1.6 million miles of roads in the United States (US) are unpaved. In under-developed and developing countries, unpaved roads or unsurfaced pavements account for an even larger share in the total number of road miles. The absence of bound surface layers in these pavements results in direct application of traffic loads to the aggregate layer. Most methods used for thickness design of unsurfaced pavements are based on subgrade strength as the primary design consideration without giving much consideration to aggregate material quality. This paper presents findings from a recently completed research study at the University of Illinois aimed at investigating the effects of aggregate type and quality on unsurfaced pavement performance. Five full-scale unsurfaced pavement test sections were constructed at different combinations of aggregate quality and subgrade strength, and were tested to failure using the University of Illinois AcceleratedTransportation Loading Assembly (ATLAS). Pavement performance was monitored through surface profile measurements as well as transverse scanning using Ground Penetrating Radar (GPR). The use of different field modulus measurement techniques was also pursued for identifying anomalies in construction conditions, and for justifying observed trends in test section performance. The performance of two different test “cells” constructed using uncrushed gravel with high fines and crushed limestone with low fines, respectively, were quite different.

SN - 9780415621380

SP - pp 483-492
AB - Predicting asphalt fatigue evolution in the field is difficult. Very few models are effective for this complex process, and even less where actual damage levels, determined from structural evaluations, can be efficiently incorporated to improve previous performance predictions. One model evaluated, CalME (California Mechanistic-Empirical Software for Structural Design of Flexible Pavements), incorporates an incremental-recursive procedure based on mechanistic-empirical principles and was used to study and reproduce the deterioration process at the CEDEX Test Track. Experimental data for this evaluation came from four full-depth pavements tested over 28 months at the track, during which bearing capacity and surface cracking data was collected. This provided detailed information regarding asphalt layer deterioration under changing environmental conditions. Special attention was paid to the accumulation of damage as a function of loads and temperature and how this damage, together with aging and post-compaction under traffic, determine the stiffness of the asphalt layer. This paper presents experimental evidence that supports the ability of the CalME model to reproduce the main aspects of asphalt performance in flexible pavements and to predict future asphalt mixture performance, after recalibration from field data. The model was initially calibrated from laboratory fatigue tests and later recalibrated based on FWD tests conducted at an early stage of the deterioration process. After this early recalibration, the model was able to predict future asphalt layer deterioration until an ultimate damage level was reached.

AB - Within the framework of the French National Research Agency (ANR), the project “Recyroute” aims to investigate the use of Fiber-reinforced Roller-Compacted Concrete (FRCC®) mixed with Reclaimed Asphalt Pavement (RAP) for heavy traffic road pavements. It comprises an accelerated pavement test conducted by means of the Accelerated Pavement Testing (APT) facility at IFSTTAR. Eight different structures were tested, including a reference section constructed with bituminous material, one structure constructed with ERTALH® gravel (RAP aggregate treated with hydraulic binder), and six other structures constructed with FRCC® materials. An associated laboratory test program was carried out to determine the mechanical properties of ERTALH® and FRCC® materials with respect to pavement design applications. This paper presents the main features and results of this APT experiment and the associated laboratory tests, leading to propose practical parameters for the thickness design of these innovative pavement structures, according to the French rational pavement design method.

AB - This paper presents a discussion of the use of Mechanistic-Empirical (ME) analysis to simulate Accelerated Pavement Testing (APT) results in order to overcome problems with using APT data, such as differences in underlying conditions, construction quality, loading, and environmental control.This is particularly important when APT results are used for comparison studies between different pavement alternatives. In the process presented, APT results are first use to calibrate ME models so that the results from simulation of APT under actual conditions match the results predicted by the models. The APT results are then simulated with ME, this time assuming uniform conditions in the APT, to produce a ranking of the alternatives tested without the bias of differences between APT sections. Extrapolation of APT results to field conditions using ME analysis is also discussed. The paper presents a demonstration of this process from an experiment to compare different asphalt overlay treatments for reflective cracking and rutting performance.

PY - 2012
SP - pp 505-517
AB - This paper presents results of a full scale accelerated test performed on the IFSTTAR pavement fatigue carrousel, to study the effect of various multiple axle combinations on bituminous pavements. The tested combinations correspond to the permissible maximum loads in France for the following axle systems: tridem axle (255 kN), tandem axle with dual wheels (210 kN), tandem axle with single wheels (170 kN) and single axle with dual wheels (130 kN). Recently, however, the French road carriers’ federation was authorized to change the vehicle load from 400 kN to 440 kN. The consequences of this increase are also discussed. The test was performed on two thick bituminous pavement sections consisting of a 16-cm granular subbase and a 26-cm thick bituminous layer. Both pavements were instrumented with strain gages, vertical displacement and temperature sensors. The objective of this research is to compare the strain signals and the maximum strain levels obtained for different axle combinations and temperature conditions and then, to compare the results with classical pavement design calculations to assess the relative aggressiveness of the different axle systems. The fatigue life of the two pavements, however, was not studied because, owing to their thickness, too many load cycles would have been required to complete a full fatigue test.

AB - Accelerated Pavement Testing (APT) has always been conducted with the objective of improving the understanding of real pavements under real traffic and environmental conditions. While APT provides an accelerated view of some of the major structural behavior to be expected from tested pavements, and while various environmental conditions can typically be simulated during APT, it is important to link the results obtained to real world pavement behavior to enable outputs from APT to be calibrated for use in general pavement design and analysis. One way of conducting this type of calibration is to conduct Long-Term Pavement Performance (LTPP) evaluations on similar pavements to those tested under accelerated conditions and to relate this information to the APT data to calibrate the them for general use (inclusive of normal traffic and environmental conditions). This paper evaluates six years of APT and LTPP data from two road sections in South Africa. The results of the APT tests are compared to the LTPP data and the pavement behavior models obtained from the APT calibrated to real-world outputs. Various concepts required to conduct these calibrations are discussed and the general procedure is reported. It is recommended that more LTPP sections be assessed in conjunction with APT, which should result in more realistic application of the APT data in that the effects of more real-time environmental and traffic applications will be incorporated into calibrated models.

AB - This paper highlights findings of a case study using cost-benefit analysis to determine economic benefits resulting from Accelerated Pavement Testing (APT) with a Heavy Vehicle Simulator (HVS) in California. The University of California Pavement Research Center (at UC Davis and UC Berkeley) and its research partners started APT in 1994 on behalf of the California Department of Transportation and is now in its 17th year of existence. The results presented in this paper follow a pilot study intended to define a method suitable for measuring the direct economic benefits from APT. The method used was initially developed and applied in Australia and later enhanced in South Africa for the respective APT programs. Enhancements to the Australian/South African methods and application to California APT program are discussed. The case study evaluated benefits (in terms of agency and road user cost savings) from HVS tests performed to validate innovative pavement mixes and designs. The method was successfully applied and showed benefit-cost ratios ranging from about 2:1 to 17:1 (depending on discount rate), which is in the range of previous studies in Australia and South Africa. Due to the uncertainties and subjective nature of this technique, sensitivity analysis is recommended to determine a range of savings instead of a single benefit-cost ratio.

AB - The main objective of this study is to calibrate CalME, a Mechanistic Empirical (ME) analysis and design program for new flexible pavements and rehabilitation, rutting prediction models using the results of Heavy Vehicle Simulator (HVS) experiments. The methodology followed a shear-based Incremental-Recursive (IR) procedure using rutting model coefficients determined from laboratory shear testing. Calculated calibration coefficients for different HVS test sections were compared to evaluate the effects of asphalt mixture and structure type on predicted rutting performance. HVS rutting experiments were performed on four sections making up a full factorial of mix type PG64-28PM [polymer modified dense-graded] and RHMA-G [rubberized gap graded]) and thickness (65mm and 115mm [2.5 and 4.5 in.]). HVS test results and early failure of RHMA-G mixes were also investigated to determine the changes in asphalt concrete micro structure with HVS trafficking using X-ray Computed Tomography (CT) images taken before and after HVS rutting tests.Three-dimensional images of deformed and un-deformed specimens were compared to determine the changes in air void content distributions for the PG64-28PM and RHMA-G mixes. Results of the analyses showed that shear related deformation controls the long term rutting performance of the test sections while densification was only an initial contributor at the very earlier stages of the trafficking. Laboratory shear testing was also determined to be an effective experiment for rutting performance evaluation. CalME was able to predict the early failure of the test sections constructed with the RHMA-G mix.

AB - Full-scale Accelerated Pavement Testing (APT) is conducted by a number of international facilities with APT devices and who have funding to conduct this type of testing. There are a host of countries who cannot afford such programs and miss the opportunity of obtaining potential APT benefits. Although the objectives of each APT program differ, the results of different APT programs can often be complimentary when viewed holistically and not on a program by program or client by client basis.A compilation of the outputs from APT programs linked to the Heavy Vehicle Simulator International Alliance (HVSIA) has been used in this paper to generate an empirical pavement design catalogue for preliminary pavement thickness design. Surface rut was used as the failure condition for the catalogue. The paper focuses on the process followed and the outcomes of the study.

AB - A response model to be employed in a mechanistic-empirical pavement performance prediction model based on multilayer elastic theory has been developed. An iterative approach using a method of successive over-relaxation of a stress dependency model is used to account for the nonlinear behavior of unbound materials. Asphalt and subgrade materials are assumed to be linear elastic. The response model was verified against two series of Heavy Vehicle Simulator (HVS) response measurements made under a variety of wheel load configurations and at different pavement temperatures. A comparison with Falling Weight Deflectometer (FWD) data was also carried out. The model was subsequently used to predict permanent deformation from the HVS testing using simple work hardening models. A time hardening approach has been adopted to combine permanent deformation contributions from stress levels of different magnitude. The response model outputs and the predicted permanent deformations were generally in good agreement with the measurements.

The authors’ intent is to aid in translating technical pavement benefits well known to APT experts into quantitative measures and qualitative indicators so the public, decision-makers, and others who lack pavement expertise (but who may have interests such as funding and staffing APT activities) can understand and appreciate the benefits from their investments in APT research. APT researchers and owners/operators both individually as well as the broader APT research community comprise the intended audience for this paper. The paper (1) reviews and compares qualitative and quantitative techniques including direct economic benefits assessments, (2) describes challenges to the evaluation process, (3) highlights trends that make evaluating benefits of APT an emerging priority, and (4) outlines new directions and potential actions for individual APT owners/operators and for the broader APT community. This paper aims to stimulate dialogue and investigations to advance the use and development of approaches that better identify, evaluate, and communicate the benefits of APT.

TI - Using Point Level Accelerated Pavement Testing Data for Calibration of Performance Models
SN - 9780415621380
PY - 2012
SP - pp 453-459
AB - Accelerated Pavement Testing (APT) data is generally expensive to collect, and one section only yields one point or series of data for the calibration of performance models for mechanistic-empirical design methods. This data is typically the mean performance from a number of sets of measurements at various locations on the section. These raw data observations cannot be used directly for calibration because they are strongly correlated with one another. This paper details methods of using these points to calibrate performance models by controlling for this correlation. The paper uses examples from Heavy Vehicle Simulator (HVS) tests used to calibrate the CalME pavement design method for flexible pavements. Using all of the available data from a section can dramatically improve the quality of the calibration, and significantly enhance the value of APT testing.

TI - Accelerated Traffic Load Testing of Seismic Expansion Joints for the New San Francisco-Oakland Bay Bridge
SN - 9780415621380
PY - 2012
SP - pp 355-364
AB - A relatively unique opportunity was recently identified for accelerated traffic load testing of a bridge expansion joint designed to withstand severe seismic activity. This study was part of the construction of the new East Span of the San Francisco–Oakland Bay Bridge and assessed whether the expansion joints (which were designed to function in harmony with the bridge decks in the event of a high magnitude earthquake) linking the Self-anchored Span with the Transition and Skyway spans would withstand traffic loading. A test structure incorporating one of the joints was constructed close to the actual bridge and tested with the California Department of Transportation/University of California Pavement Research Center Heavy Vehicle Simulator in a series of phases. On completion of three months of testing, no structural damage was recorded by any of the Linear Variable Differential Transducers (LVDTs) or strain gauges installed on the steel plates, steel frames, bolts, or washers. There was also no visible damage on any of these components. Excessive overloading caused some damage to the Trelleborg unit towards the end of the test. Based on the results of this limited testing, it was concluded that the expansion joint would perform adequately under typical Bay Bridge traffic. The distress observed to the Trelleborg unit under the high loads in the last phase of testing is unlikely to occur under normal traffic. The findings from this study indicate that the Caltrans seismic expansion joint tested will be appropriate for typical Bay Bridge traffic. These joints will be used in the new bridge, due to be opened in 2013. The study also concluded that accelerated pavement testing can be effectively used for testing bridge deck components to provide rapid answers for design and construction teams.

TI - Study of Failure Mechanisms in Rubblized Concrete Pavements with Hot Mix Asphalt Overlays
SN - 9780415621380
PY - 2012
SP - pp 343-352
AB - Full-scale traffic tests were completed on three rubblized rigid airport pavements overlaid with 5 in. (130 mm) of hot-mix asphalt at the FAA’s National Airport Pavement Test Facility. Initially, the overlaid pavements were trafficked with a four-wheel landing gear (with wander) and 55,000-lbs (25-tonne) wheel load. No significant distresses were observed during the 5,000 passes, after which the wheel load was increased to 65,000 lbs (29.5 tonnes) and a six-wheel landing gear was used for testing. The rubblized concrete pavement on conventional base section (MRC) exhibited complete structural failure. The rubblized concrete on subgrade (MRG) section exhibited severe structural deterioration at the end of trafficking, but retained sufficient structural capacity to support the applied load. The rubblized concrete over econocrete base section (MRS) did not exhibit severe structural deterioration at the end of trafficking. Four trencheswere opened perpendicular to the centerline of the test sections to conduct post-traffic investigation into the failure mechanism of the pavement structure. The trenching included testing for layer characterization (plate load tests, California Bearing Ratio tests, in situ densities, moisture contents, layer profile measurements, and visual evaluations) and removal of each pavement layer to reveal the subgrade interface and subsequent subgrade layers below. This paper summarizes the results from the post-traffic tests. The performance of the MRS test section suggests that rubblized concrete pavements with HMA overlay are a viable option on commercial airports. The results from post-traffic tests were useful in providing insight into the failure mechanism of rubblized concrete pavements.

AB - Two Portland Cement Concrete (PCC) slabs, one dowelled and one undowelled, were placed and instrumented in the Accelerated Pavement Load Test Facility in Lancaster, Ohio. The objectives of the study were to determine the forces generated in steel dowel bars and in the surrounding concrete resulting from PCC slab deformations during curing, thermal cycling, and moving wheel loads; monitor PCC slab shape during curing and thermal cycling with LVDTs and a Dipstick®; measure strain generated in the PCC slabs from moving wheel roads traversing the slab; and determine the magnitude of residual stress remaining in the slabs by taking cores at the rosette locations at the conclusion of testing. The slabs were cured at a constant temperature, and then subjected to temperature variations and wheel loads. Data were collected from the sensors and a Dipstick® was used to measure the shape of the slabs as they cured and when subjected to temperature gradients. It was found that slab temperature gradients were moderate during the curing period because of constant room temperature. LVDT data indicated that the amount of warping on undowelled slabs was much greater than on the dowelled slabs. As slab temperature gradients changed, the undowelled section had greater deflection than the dowelled section. Corner deflection increased with time during the period of constant temperature. Dowels restrained joint movement, thus reducing the amount of curling. Therefore, dowel bars not only transferred load but also reduced loss of support.

AB - Noise properties of road pavements change over time due to wear from traffic, impact of weather conditions, etc.With the introduction of noise reducing pavements in many countries, it has become increasingly important to understand how the noise properties of pavements change as they get older. The Danish Road Directorate and the University of California Pavement Research Centre have investigated the feasibility of using test results from HeavyVehicle Simulator (HVS) test sections to predict the development of the noise properties of pavements. Pavement surface textures were measured at regular intervals with a three-dimensional scanner on a range of different HVS test sections on various projects. The Dutch Acoustical Optimization Tool (AOT), developed to predict the noise properties of road pavements based on texture data, and pavement type, was used for the analyses of the measured texture profiles.

TI - Provisional Results from Accelerated Pavement Testing of Roller-Compacted Concrete in South Africa
SN - 9780415621380
PY - 2012
SP - pp 313-321
AB - In conjunction with the Gauteng Department of Roads and Transport and Cosal Consultants CC in South Africa, the CSIR Built-Environment is evaluating the applicability of Roller Compacted Concrete (RCC) as an option for the upgrading and rehabilitation of low-volume residential and provincial roads. The ultimate aim of the study is to build confidence in the use of RCC, with cognizance being taken of the pavement structure, support conditions, construction, climate, and traffic. Whereas RCC is normally constructed with a relatively low labor component and with heavy mechanical equipment, the goal of this investigation was to evaluate the structural performance of RCC constructed with a relatively high labor component using handoperated equipment. This is in line with the South African Government’s drive towards sustainable job creation, together with the pressing need for the upgrading and maintenance of the low-volume road infrastructure. Fullscale Heavy Vehicle Simulator (HVS) tests were conducted to determine the structural capacity of the RCC. This paper summarizes the provisional results from the first Accelerated Pavement Test (APT) on the control section, constructed using conventional methods and equipment. Through APT testing it was shown that this type of pavement performed exceptionally well in the dry state, even though it was constructed on a substandard support system. Initial indications are that actual performance exceeded predicted performance. Sensitivity to water is an important factor that will be investigated in subsequent testing. Testing of the labor-intensive constructed sections will be documented in a separate paper.

TI - Accelerated Pavement Testing on Slab and Block Pavements Using the MLS10 Mobile Load Simulator
SN - 9780415621380
PY - 2012
SP - pp 323-329
AB - To optimize the thickness of slab and block pavements and also to test new large-format slabs an Accelerated Pavement Test (APT) using the Mobile Load Simulator (MLS10) was carried out in Austria from September to October 2010. The APT was an international cooperation with the Swiss Federal Laboratories of Material Science and Technology, Semmelrock Ebenseer and the Vienna University of Technology. The experiment consisted of seven different slab and block pavements. Selected pavements were instrumented with soil pressure cells and horizontal strain gauges to assess primary responses under the wheel load. For the APT the MLS10 used Goodyear super single tires with a wheel load of 65 kN. The test speed was 22 km/h and no lateral wandering and no application of water was used during the tests. Falling Weight Deflectometer (FWD) measurements were taken after construction of the test sections and after completion of loading. Deformation of the surface (rut depth)was determined periodically.The results of theAPT are intended to evaluate the parameters for a developed Finite-Element Model (FEM) for slab and block pavements, which enables simulation of the whole superstructure, traffic loads and thermal stresses. The FEM is the final tool to optimize the thickness of slabs and blocks for new designs and heavy traffic areas.

AB - The LanammeUCR is an academic entity attached to the Civil Engineering Faculty of the University of Costa Rica. The Transportation Infrastructure Program (PITRA) of LanammeUCR, works directly with the Costa Rican government performing applied research, auditing and technology transfer. It is funded from a law that assigns 1% of the fuel tax collected in Costa Rica to LanammeUCR with the main objective of ensuring the efficiency of road investments in the country. To meet this objective, PITRA has allocated a considerable component of its funds towards the acquisition of high technology/state-of-the-art equipment such as an falling weight deflectometer, road surface profiler, Geo3D, and dynamic testing equipment for material characteriza- tion, among others. With the goal of improving the design and construction of pavements structures, as well as better understanding the different materials used, LanammeUCR decided to acquire a Heavy Vehicle Simulator (HVS) with instrumentation. With this Accelerated Pavement Testing (APT) equipment, LanammeUCR will be fully equipped to monitor the performance of different pavement structures and materials, and new and improved pavement technologies, and to develop and calibrate a mechanistic-empirical design guide for local weather, materials, and traffic conditions. This paper summarizes the draft plan for the design of the APT facility that will be constructed at LanammeUCR. The facility includes a saturation system to simulate pavement conditionsduring Costa Rica’s intense rainy season.

AB - Accelerated Pavement Testing (APT) offers a unique proven methodology to investigate perfor- mance of different material and pavement structures under various conditions. Case studies using Mobile Load Simulator (MLS) equipment provide well-documented information in support of this statement. The interna- tional selection of typical cases provides pavement engineers (and managers) insight into some of the lessons learned and application of the knowledge gained in respect of distress and failure mechanisms. Case studies from China, Europe, and United States are presented. These cover applications of asphalt materials including pavement surfacing, stone matrix asphalt, Guss asphalt, and full-depth asphalt. Trafficking under wet and dry as well as artificially heated conditions, are discussed. Structural compositions include a steel bridge deck surfacing, a full-scale and comparative scaled pavement, and a sandy subbase subjected to the influence of a high water table. The paper reports on a synthesis of facets of analyses and findings from the case studies including both laboratory and field applications.

AB - The need for faster and more practical evaluation methods under closely simulated in-service conditions prompted the Florida Department of Transportation (FDOT) to initiate an Accelerated Pavement Testing (APT) program in 2000. The main objective of this program is to continuously improve the performance of Florida’s pavements in a cost-effective manner. Technology transfer and implementation are also of primary importance. The APT program recognizes that such efforts are essential to reap expected dividends from this investment. All research results and aspects of innovations arising from this program are implemented as soon as practical. Over the ten years of its existence, the Florida APT program has investigated flexible, rigid, and composite pavements. This paper provides a ten year review of FDOT’s APT program. The evolution of the APT facility and program are described. Results from several projects are summarized and benefits from implemented technology and practices are highlighted.

SN - 9780415621380
PY - 2012
SP - pp 121-131
AB - This paper presents an experiment conducted on the pavement fatigue carrousel of IFSTTAR. Several defects (debonded areas or transverse vertical cracks) were intentionally incorporated during construction. Before the start of the loading planned in March 2012, different non-destructive test techniques were used to detect and locate these artificial defects. Two different electromagnetic wave techniques were tested: Ground Penetrating Radar (GPR) with horn or coupled antennas and a higher frequency system (step frequency radar). Deflection basin measurements with a Falling Weight Deflectometer (FWD) were also taken. Another technique based on Frequency Response Function (FRF) in intermediate frequency domain (100–10,000 Hz) to detect and locate the defects showed interesting results. Further measurements will be made with these different techniques during the experiment to assess the evolution of the defects. It will also allow comparison of the ability of each technique to detect such damage, to precisely quantify their limits of application, and to optimize the survey process of roads.

AB - Asphalt strain gauge installation procedures have typically used hot mix sieved through a 4.75 mm screen, hand placed over the gauges and hand compacted prior to roller compaction which has led to a high gauge survival rate. This finer mix in the immediate vicinity of the gauge could theoretically yield lower moduli and higher strains. The objective of this study was to evaluate the potential effect of using a finer mix as gauge cover on pavement response. Finite element analysis was used to simulate a three-layered pavement structure containing a patch of sieved material at the bottom of the asphalt concrete layer. Tensile strain responses were calculated at the bottom of the asphalt concrete layer under a single load for all structures with and without the finer mixture. The results were compared to a previously defined benchmark of 30 µε which was more likely tobe exceeded with layers thinner than 5 in. and moduli between 200 and 500 ksi.

AB - This paper describes the design and fabrication of a Data Acquisition (DAQ) system that uses the latest hardware and software technology. Two systems were built to work with two active Heavy Vehicle Simulators (HVS) at the University of California Pavement Research Center (UCPRC). The new DAQ systems replaced the old ones that were built in 2005. The upgrade was considered necessary because the data acquisition hardware used in the old systems were no longer actively supported by the vendor. The new system maintains the ability to measure temperature, displacement, strain, pressure (voltage) and surface profile. In addition, the new system can also measure resistance and current. A modular design was adopted to facilitate future upgrades without having to replace all of the components. It also allows sharing and balancing of the DAQ needs between the two HVS units. It is believed that the design of the new DAQ system is sufficiently generic and can provide useful information for other accelerated pavement testing programs.

AB - The Accelerated Pavement Testing (APT) program at Kansas State University (KSU) has been in existence for the past 14 years. The Midwest States Accelerated Pavement Testing Pooled Funds Program, a consortium of the Departments of Transportation of Iowa, Kansas, Missouri, and the Nebraska Department of Roads, has been the sponsors for the majority of the tests. Sixteen full-scale pavement tests have been completed since 1997. The majority of the tests were done for side-by-side comparison of new products or processes for both asphalt and concrete pavements. These tests successfully evaluated new products or practices and verified current pavement designs and/or practices for four Midwestern states. Results of a multi-year experiment are now being used for calibration of the new Mechanistic-Empirical Pavement Design Guide (MEPDG) procedure models in Iowa, Kansas, and Missouri. This paper summarizes the confirmation of practices and improvements in highway pavement design and construction that have resulted from the tests conducted at this APT facility. Major findings along with the lessons learned from these experiments are described.

SP - pp 85-91
AB - MnROAD was built in the early 1990s and has seen 26 construction events throughout its nearly 20 years of operations. MnROAD has three roadway segments that consist of various 500 foot test cells. There are currently 30 Mainline cells (on Interstate I-94), 24 Low Volume Road cells (trafficked by a Minnesota Department of Transportation [MnDOT] 80,000 pound 5-axle truck), and some specialized cells located in other locations around the facility. As test cells fail other test cells are designed and reconstructed to keep each of the road segments operational. Since cells are designed to fail, each cell has a different life span and failures can occur at any time. MnROAD is owned and operated by MnDOT, and most construction events have been limited to “traditional” design-bid-build practices. Over the years MnROAD has stretched what is considered “typical” in the way partnerships have been developed to encourage designs using non-standard specifications, new and innovative construction methods, and finance with other partners all while working in a system that is rich in a traditional contracting process. This paper’s purpose is to document the past construction events that have taken place over the years and highlight what has worked and what has been problematic for MnROAD as a MnDOT (state government) run facility. Its audience and focus is directed to help MnROAD and other agencies struggling to incorporate research into construction. The paper will also suggest other contracting options that incorporate innovative research into future construction.

AB - This paper describes the development of a new apparatus to perform accelerated loading tests on pavement structures. This apparatus is the main component of the laboratory of physical modeling of pavements at the University of Los Andes in Bogotá Colombia. The components of this laboratory are: (i) a concrete pit 11.4 m long, 3.2 m wide and 3.5 m deep; the pavement structure is constructed in this pit and it allows the control of the water table and the environmental conditions over the pavement surface; (ii) the linear loading test apparatus, and (iii) a mini asphalt plant that simplifies tests with modified asphalt materials. The loading apparatus is a linear test track that applies the load of a half axle truck (dual tires with maximum load of 75 kN). This new linear test track has an original control system based on the combination of an electrical frequency power controller, and a set of air springs. The air springs absorb the energy of the moving load when slowing down close to the ends of the track, and it allows generation of energy during the acceleration process. This system permits high velocities while saving energy. This paper describes the main components of the apparatus and presents some results of a first test carried out using this new APT device.

TI - Accelerated Loading, Laboratory and Field Testing Studies to Fast-track the Implementation of Warm Mix Asphalt in California
SN - 9780415621380
PY - 2012
SP - pp 165-173
AB - The use of Warm-Mix Asphalt (WMA) has increased substantially in recent years and considerable funding has been allocated to research on the topic. Some road authorities have implemented its use based only on results from limited testing, while other states have adopted a more conservative approach. Given the significant differences to Hot-Mix Asphalt (HMA) practice and fears of a moratorium on the use of the technology if unexplained problems occur, the California Department of Transportation decided to follow a more conservative approach, by designing and implementing a phased comprehensive study. Phase 1 investigated rutting behavior of three different WMA technologies against an HMA control in an accelerated loading test with associated laboratory testing assessing rutting and fatigue performance and moisture sensitivity. A number of controlled pilot studies were also constructed during this phase. Phase 2 investigated the effects of the same three WMA technologies on moisture sensitivity in an accelerated loading test. Phase 3 investigated the use of seven different WMA technologies in rubberized asphalt following the same testing program used in Phase 1. The findings have been used to prepare a WMA technology approval process and a framework for statewide implementation that resulted in over one million tons of warm-mix asphalt being placed on state highways in the 2011 paving season. This paper provides an overview of the California WMA study and summarizes the results of the accelerated load and laboratory testing completed to date.

TI - Direct Measurement of Residual Stress in Airport Concrete Pavements
SN - 9780415621380
PY - 2012
SP - pp 141-146
AB - The current Federal Aviation Administration design procedures for airport concrete pavements do not directly consider top-down cracking. However, this distress has been repeatedly observed in full-scale tests conducted at FAA’s National Airport Pavement Test Facility (NAPTF) and AIRBUS in Europe. Generally, the maximum load stress related strain near the slab bottom is mostly higher than the strain near the surface.Therefore, the cause of early appearance of top-down cracks remains unknown. Neither minimizing the curling nor increasing the slab thickness could effectively control cracks initiated from the surface. For top-down cracking, the total stress is considered a key factor. This is the sum of residual stress that exists in the pavement before a load is applied and the load induces any stress. Therefore, direct measurement of residual stress appears to be a new approach towards a better estimation of the total stress. Two testing methods, coring and saw-cutting, have been investigated, improved upon, and evaluated through a number of FAA sponsored research projects. Some residual stress measurements using both methods are presented. Future work will focus on the effects of residual stress on top-down cracking risk for field practice.

AB - The condition of Florida roadways is documented through annual surveys conducted by the State Materials Office (SMO) of the Florida Department of Transportation (FDOT). This survey has shown that the majority of the deficient flexible pavements are due to cracking. Based on these circumstances, FDOT’s Accelerated Pavement Testing (APT) program has placed a greater focus on deficiencies in the evaluation of crack development and crack resistance. As part of this effort, a computer based program has recently been developed to assist with the identification and quantification of pavement cracks from digital images. A digital camera mounted in front of the wheel carriage on the Heavy Vehicle Simulator (HVS) collects the images at regular intervals during testing to document initiation and the progression of crack development. This paper provides a description of the crack analysis system and offers an example of its use.

AB - Full-scale Accelerated Pavement Testing (f-sAPT) has been conducted for almost 50 years in various forms. The NCHRP requested an evaluation of the last decade of f-sAPT to assess the status quo, identify major developments and trends, as well as the general perception of US Departments of Transport and f-sAPT operators regarding the role and impact of f-sAPT. This paper summarizes the results of the synthesis and captures developments and trends in f-sAPT since 2000, with a focus on the specific areas of major developments, changes in operating procedures, and the effect that f-sAPT in general is perceived to have had on the development of pavement engineering. It is concluded that the judicious use of f-sAPT contributes to and supports the body of knowledge regarding the way that pavement materials and structures react to controlled traffic and environmental loads.

SN - 9780415621380
PY - 2012
SP - pp 39-45
AB - A new full-scale accelerated pavement testing facility is being designed and implemented in Beijing, funded by the National Development and Reform Commission (NDRC), People’s Republic of China. This facility is designed as a loop consisting of two semi-circular and two straight test tracks, around which a pilotless vehicle with the maximum weight of 45,000 kg and maximum speed of 60 km/h moves repeatedly. The facility is enclosed, allowing control of environmental conditions including temperature, moisture and ultraviolet radiation. This facilitates testing under simulated extreme conditions experienced in different regional areas throughout China. A general description of components of this system, including the Auto-Vehicle Loading Subsystem, Environment Conditioning Subsystem, Data Collection, Central Controlling Subsystem, and the Testing Loop Subsystem, is summarized together with the proposed system capabilities or parameters. The factors considered during the design phase of this facility are discussed, including the pavement section geometries. A three-dimensional finite element asphalt pavement model subjected to the proposed moving automobile was established to obtain the dynamic response of the designed pavement section and evaluate its dimensions. The result shows that the proposed dimensions of the designed pavement section are appropriate according to the response variation along the pavement section.

AB - New Zealand has been running a nationally funded APT program since 1968, which has produced a number of outcomes that have been implemented into New Zealand practice. Pavement response measurements allowed the national roads authority to adopt the mechanistic based Austroads Pavement Design Guide in 1995 and have also contributed to the development and verification of RLT testing protocols and have helped calibrate and benchmark LTPP sites. Projects have been either initiated due to issues arising from the performance of in-service pavements or where new construction technologies or materials have been proposed. These projects have included pavement curvature prior to the placing of thin asphalt surfaces, foamed bitumen stabilization, aggregate specifications, pavement loading at various levels for High Productivity Vehicle regulations, and a study on the dynamic effects of various vehicle suspensions.

TI - Rut Depth Measurement Method and Analysis at the FAA's National Airport Pavement Test Facility
SN - 9780415621380
PY - 2012
SP - pp 133-139
AB - The FAA developed and modified a truss profiler, which is independent of pavement profiles, that is used to monitor rutting of flexible pavements at the National Airport Pavement Test Facility (NAPTF). The truss profiler was developed to replace the more labor-intensive and time-consuming straightedge measurements. Transverse profiles corresponding to the cumulative number of load repetitions applied during traffic tests were measured using a laser displacement sensor mounted and running on a customized 20 m (66 ft.)-long aluminum truss. The profiler is capable of measuring ruts caused by 10-wheel aircraft gear configurations having dual-wheel spacing of 137 cm (54 in.) in two traffic lanes. Maximum transverse measuring width is 18.3 m (60 ft.) and upheaval outside the wheel track areas is included in all rutting measurements. The profiles reported in this paper were measured on a flexible pavement test track with a single 12-ft.-wide traffic lane. The collected profile data was processed using an FAA developed computer program to calculate the maximum rut depth, upheaval, and straightedge-simulated rut depth measured relative to the initial transverse (baseline) profiles. Trafficked profiles were shifted vertically (and/or horizontally), and rotated to compensate for differences in the setup of the profiler. The method of rut depth measurement is presented and the accuracy of the profiler is reviewed. Possible errors in measurements such as truss fluctuations in temperature, structural curvature, and cross slope of the pavement are identified. Detailed descriptions of the adjustment methods used to correct for the identified errors are presented. The geometric changes of the transverse profiles are shown with increasing number of load repetitions superimposed on the untrafficked baseline profiles. Analysis of the profiles shows the effects of lateral wander, loading induced stress, and tire pressure on a Hot Mix Asphalt (HMA) pavement surface layer. The processed rutting performance data obtained from the NAPTF test pavements are presented and discussed. Specific discussions include characterization of HMA failures showing tertiary flows from the collected data.

AB - The NCAT Pavement Test Track is a unique accelerated pavement testing facility that has now been operational for over 10 years. It is a cooperative project with individual test sections sponsored by highway agencies and commercial interest groups. This paper highlights key findings since the first heavily loaded tractor-trailer made the inaugural 2.7-km journey around the track over a decade ago. Test track findings have already resulted in numerous improvements in current asphalt pavement specifications, and the research will continue to pay dividends for years to come. Findings span the industry areas of mix design, aggregate and binder characteristics related to performance, structural design and tire-pavement interaction. This report is a summary of findings related to each of these five areas.

AB - As state agencies have started to transition from an empirical pavement design method to a Mechanistic-Empirical (ME) approach, it has become necessary to further evaluate the material properties and structural characteristics of newer sustainable pavement technologies. The objective of this study was to evaluate pavement responses and short-term performance for different sustainable pavement sections placed at the National Center for Asphalt Technology (NCAT) Test Track. The Test Track was reconstructed in the summer of 2009 and part of the experiment included six new structural sections built using several sustainable technologies. Falling Weight Deflectometer (FWD) testing and strain and pressure measurements under live traffic loads were obtained periodically under different environmental conditions. Results indicated that pavement responses changed significantly for some sustainable sections. Field performance measurements showed that rut depths were influenced by the use of sustainable technologies, but all sections performed well overall with less than10 mm of rutting. No cracking had been observed in any of the sections after 20 months of operation and over8 million applied ESALs.

SN - 9780415621380
PY - 2012
SP - pp 175-185
AB - A controlled environment study of perpetual pavement was conducted at the Ohio Research Institute for Transportation and the Environment’s Accelerated Pavement Load Facility (APLF). The surface layer of each section consisted of one of the Warm Mix Asphalts (WMA), Aspha-min, Sasobit, and Evotherm, or a hot-mix control. The test sections were divided into northern and southern halves, with the northern halves having a full 16 in. (400 mm) perpetual pavement; the southern halves had intermediate layer thicknesses decreasing in 1.0 in (25 mm) increments, which was compensated for by increasing the thickness of the dense-graded aggregate base. Instrumentation in the southern half was used to measure temperature, subgrade pressure, deflections, and longitudinal and transverse strains at the base of the fatigue resistance layer. The temperature was set to 40◦ F (4.5◦ C), 70◦ F (21◦ C), and 104◦ F (40◦ C), in that order. At each temperature, Rolling Wheel Loads (RWL) of 6,000 lb (26.7 kN), 9,000 lb (40 kN), and 12,000 lb (53.4 kN) were applied at selected lateral shifts and the sensor responses measured before and after being subjected to 10,000 passes of 9,000 lb (40 kN) RWL at ∼5 mph (8 km/h). Profiles were measured after 100, 300, 1,000, 3,000, and 10,000 passes to assess consolidation of each surface.

AB - While some state agencies look at using recycled products in asphalt mixtures as a means to become more environmentally-friendly, other states and contractors are investigating materials like Ground Tire Rubber (GTR) as a substitute for polymer modification in asphalt binders. The Missouri Department of Transportation recently built two test sections at the National Center for Asphalt Technology (NCAT) Pavement Test Track to validate the use of GTR as a substitute for Styrene-Butadiene-Styrene (SBS) in asphalt mixtures. The Test Track sections were monitored weekly over a two year period for field performance including rutting, smoothness, and texture using an inertial profiler. Monthly crack maps were also developed to assess mixture cracking. Additionally, each mixture was sampled for laboratory characterization in terms of stiffness, rutting, cracking, and moisture susceptibility using standard laboratory procedures. Based on the gathered data, GTR mixtures can be used as an adequate polymer substitute without sacrificing asphalt mixture performance.

TI - FAA Aerospace Forecast, Fiscal Years 2012-2032
PY - 2012
SP - 124p
AB - This forecast looks at how many planes and how many people will fly on U.S. carriers over the years 2012 to 2032. As the economy continues to recover, the number of takeoffs and landings and the number of passengers who board U.S. airlines are expected to continue to climb with a steady, moderate growth, as they have in the last two years. The forecast calls for a slight decrease (less than one percent) in domestic capacity in 2012, as measured by available seat miles. This is after a 2 percent increase in 2011. Despite this pause in growth, the Federal Aviation Administration (FAA) projects continued growth between 2 percent and 3 percent per year over the next 20 years. This year’s forecast predicts that the industry will grow from 731 million passengers in 2011 to 1.2 billion in 2032. Cumulatively, air traffic growth for U.S. carriers–measured by revenue passenger miles–is expected to rise by more than 90 percent in the next 20 years. It grew by 3.5 percent in 2011. Airport tower operations are expected to increase by 23 percent. Also, the number of aircraft handled at FAA en-route centers, which separate high altitude traffic, is expected to increase by 50 percent. Over the next 20 years, large airports will continue to grow faster than their smaller counterparts in the United States. FAA is forecasting that the number of larger regional jets will increase, while most of the smaller regional jets will be retired from the fleet. On the general aviation front, the demand for products and services will continue to grow, particularly in new business jets and light sport aircraft. As the U.S. aviation system advances into the next century of flight, the solution for handling the demand for service is the Next Generation Air Transportation System, or NextGen. The FAA is in the process of transforming the U.S. national air space system from the ground-based radar of today, to the satellite-based system of tomorrow. This is a fundamental change in the way the United States and the world will navigate and control air traffic.

TI - New Approaches Are Needed To Strengthen FAA Oversight of Air Carrier Training Programs and Pilot Performance
PY - 2011/12/20/Audit Report
SP - 28p
AB - For more than a decade, the National Transportation Safety Board (NTSB) has called for the Federal Aviation Administration (FAA) to incorporate safety improvements impacting pilot performance and professionalism. NTSB determined that the cause of the fatal 2009 crash of Colgan Air flight 3407 was due in part to pilot failure to follow appropriate procedures. In June 2009, 4 months after the crash, FAA announced its Call to Action Plan, which included 10 short- and mid-term initiatives to enhance pilot performance and training, increase air carrier participation in voluntary safety programs, and expand pilot records review. The Senate Committee on Commerce, Science, and Transportation and the House Committee on Transportation and Infrastructure requested that the Department of Transportation Office of Inspector General (OIG) review FAA’s oversight of airline pilot training programs to determine whether pilot training is up to date, and to what extent FAA can verify pilots are receiving appropriate training. The Committees also requested that OIG determine what actions apply when pilots repeatedly fail training or other tests, what information pilots must provide airlines when hired, and whether this information is sufficient to verify pilot employment and training. This request was also reiterated by Representatives Louise Slaughter and Brian Higgins. This report provides the results of OIG's audit to (1) assess FAA’s oversight of air carrier pilot training and proficiency programs and (2) examine the data FAA maintains on pilots’ qualifications and past performance and the process air carriers use to obtain these data when hiring. Briefly, results of the audit indicated that FAA’s oversight of air carriers’ pilot training and proficiency programs lacks the rigor needed to identify and track poor performing pilots and address potential program risks. FAA maintains extensive pilot information that air carriers can use to evaluate the competence and qualifications of pilots; however, its current request process hinders air carriers’ ability to easily obtain all relevant data.

TI - Synthesis of Information Related to Airport Problems. Topic S10-09. Airport Wildlife Population Management
AB - Aircraft collisions with birds and other wildlife pose a significant risk to and cost the aviation industry hundreds of millions dollars in damage and lost revenue every year. The majority of wildlife strikes occur within the airport environment, thus the responsibility for mitigation falls upon the airport operator. Airports are often located next to wildlife attractants such as waste management/transfer facilities, water management facilities, wetlands, agriculture, shorelines, wildlife refuges and other habitats that provide food, water and sheltering areas for birds and other wildlife. To reduce of wildlife using airports or their surrounding areas, an integrated approach utilizing multiple strategies should be considered, including; habitat modification, exclusion, hazing/harassing techniques, and population management. The objective of this synthesis project is to describe procedures and projects at representative airports used to manage wildlife population in order to minimize wildlife strike potential in the vicinity of airports. Airport operations staff and wildlife biologists responsible for airfield safety and wildlife management are the target audience for this report. The report would synthesize literature and practice relating to Wildlife Hazard Assessments, Wildlife Hazard Management Plans and programs/projects to deter wildlife through population management to minimize wildlife strike potential in the vicinity of airports. Information on methodologies, biology, effectiveness and costs needed to implement the population management portion of an airport's wildlife hazard management programs would be included, as well as a representative set of examples of airports using population management to manage diverse wildlife species across North America.

TI - Synthesis of Information Related to Airport Problems. Topic S01-05. Airport Organization
AB - A well-understood and effective organizational structure can greatly assist an airport in meeting strategic and business goals. Many times, the development of a strategic plan or articulation of business goals leads an airport operator to examine and modify the organizational structure to better achieve those goals. The objective of this report is to provide airport operators with a synthesis of organizational structures, including functional roles and key staff, to support success of strategic and business plans. The intended audience for this synthesis of practice is airport executives and their governing boards. This synthesis of airport practice will explore the role and types of airport governance and organizational structures and their effectiveness in meeting the strategic goals of airport executives and their governing bodies.

TI - Reducing Energy Use & Maintenance Cost with On-demand Escalators and Moving Walkways
AB - Many airports require passenger processing circulation patterns that use multiple floor levels and lengthy walking distances. To increase efficiency, capacity, and the quality of customer service, facility designers have employed a variety of mechanized circulation devices, including elevators, escalators, and moving walkways. In addition to the capital expenditure associated with these mechanized devices, they also consume energy, contribute to increased air emissions, and require maintenance. Escalators and moving walkways are designed under U.S. elevator and escalator codes (ASME A17.1a-2008) to operate in continuously moving modes as long as terminal facilities are open, which at major airports often equates to 24/7 operation, whether passengers are using the conveyances or not. This has been recognized to result in the unnecessary consumption of electricity, greater generation of air emissions, and increased maintenance costs. Many facilities outside the United States, including airports, feature "on-demand" passenger conveyance systems that sense passenger activity and either slow down or stop during periods with no demand, thereby reducing energy consumption, air emissions, and maintenance needs. These on-demand devices could prove to be beneficial at U.S. airports. The objectives of this research are to determine the potential benefits of on-demand escalators and moving walkways in terms of reduced energy use, air emissions, and maintenance costs, and to describe the implications of modifying elevator and escalator codes to permit these technologies in the United States.

TI - Sustainable Practices for Airport Maintenance and Operations
AB - Sustainability practices are increasingly implemented into the areas of airport operations and maintenance. Often, airports are incorporating these initiatives in an ad-hoc manner, without the benefit of a comprehensive assessment of whether the measures are, in fact, sustainable for their particular situation. It is prudent for airports to assess the budgetary and operational implications of various sustainable practices, as some may require more maintenance and upkeep than originally anticipated. Yet the assessment of whether a particular practice is truly sustainable can be complex and may be beyond the existing expertise level of airport staff, and there is no guidance on how to assess the impact of sustainability practices on an airport's operations and budget. The objective of this research is to provide guidance for airports to help them more fully understand the budgetary and operations implications of undertaking the most common sustainability practices.

TI - Legal Aspects of Airport Programs. Topic 04-06. The Role of the Airport Sponsor in Airport Planning and Environmental Reviews of Proposed Development Projects Under the National Environmental Policy Act (NEPA) and State Mini-NEPA Laws
AB - Responsibility for compliance with National Environmental Policy Act (NEPA) rests with the Federal Aviation Administration (FAA). However, as the project proponent, the airport sponsor plays a significant role, for example, in identifying and defining the proposed action. This paper will explore the legal issues presented in fulfilling requirements under NEPA, related federal environmental laws, and analogous state mini-NEPA statutes in selected jurisdictions. For example, the paper should explore the extent and means by which an airport sponsor desiring to reach its goals may be considered. The paper should (1) summarize criteria typically used to define purpose and need and screen and evaluate the feasibility of alternatives, including federal statutory mission and objective factors such as safety and operational efficiency; (2) discuss the relationship between the amount of information the airport should submit and the type of NEPA action anticipated (e.g., categorical exclusions vs environmental impact statements); (3) include practical advice and strategies for addressing typical issues such as exchange of draft environmental documents after the ruling in US Department of Interior vs. Klamath Water Users Protective Association National Environmental Policy Act , 532 US 1 (2001). Sources of information for the analysis should include FAA Order 5050.4B, relevant case law, legal treatises, and law review articles.

TI - Understanding Green Energy Technologies and Their Effects on Airports
AB - New energy technologies must consider aviation safety and airport safety concerns. The Federal Aviation Administration (FAA) has recently published Technical Guidance for Evaluating Selected Solar Technologies on Airports (November 2010). The Airport Cooperative Research Program (ACRP) Synthesis S10-10-06, "Investigating Safety Impacts of Energy Technologies on Airports and Aviation", now in publication, is taking another step in focusing on the effects various energy technologies have directly on airports. Initial findings and discussions with experts suggest, though, that the scope of the safety hazards is much greater, extending far beyond the immediate airport environs. This proposal expands upon existing research and FAA guidance and would evaluate the effects energy technologies have on the entire air transportation system, including airplanes in flight, away from the airport environment. The objective of this research is to produce a guidebook that may be utilized by airports and other stakeholders to assess and mitigate potentially negative impacts that green energy technology may have on airports and aviation. Using results of existing FAA guidance and ACRP synthesis of practice, this research would identify which emerging energy technologies impact the overall air transportation system, including all locations away from airports; assess existing analysis techniques used to determine which represent safety hazards to the air transportation system; identify roles and responsibilities of individual energy infrastructure developers and agencies that may impact safety to airports and aviation from energy technologies; and develop approaches to assess and mitigate these potentially negative impacts where appropriate.

TI - Guidebook for Energy Facilities Compatibility with Airports and Airspace
AB - Projected demand for energy will increase in the upcoming years requiring the development of new or expanded energy sources. Recognizing the need to significantly increase energy production and transmission infrastructure, energy stakeholders must consider aviation safety and airport safety concerns. The Federal Aviation Administration (FAA) recently published the Technical Guidance for Evaluating Selected Solar Technologies on Airports (November 2010). The Airport Cooperative Research Program (ACRP) Synthesis 28: Investigating Safety Impacts of Energy Technologies on Airports and Aviation takes another step in describing how various energy technologies affect airports. Initial findings and discussions with experts suggest, though, that the scope of the safety impacts may be greater, extending far beyond the immediate airport environs. Research is needed to further evaluate the safety effects that energy technologies may have on the air transportation system, (including aircraft in flight and on and off the airport environment) and to develop best practices to address such effects. The objective of this research is to produce a guidebook, supported by empirical evidence, that provides best practices for aviation safety associated with planning, developing and constructing energy production and transmission technologies at and around airports. The guidebook should include at a minimum: (1) A review of FAA guidance, related ACRP and other research, and relevant federal and state regulations. Acknowledge any overlap, such as FAA and Federal Energy Regulatory Commission regulations; (2) Descriptions of different types of energy technologies that could be installed in and around airports, including but not limited to, solar, wind, power generation plants, oil and gas drilling, and electricity transmission lines and towers; (3) Best practices and guidelines for a wide range of types and sizes of airports compatible with air transportation systems, for all airspace, including special use airspace, both on and off airports; and (4) Design and siting or location guidelines for each of these types of energy technologies, in order to mitigate and minimize the impact on aviation, such as, height and distance criteria for wind turbines, distance and angular criteria for solar panels, and thermal plume effects on aviation operations.

AB - This report summarizes the analysis of 97 general aviation accidents in Alaska that resulted in a fatality or serious injury to one or more aircraft occupants for the years 2004-2009. The accidents were analyzed using the Human Factors Analysis and Classification System (HFACS) developed by Douglas Weigmann and Scott Shappell. As found in previous studies of this nature, Skill-Based Errors were found to be the most common accident causal factor, followed by Violation, Decision-Based Error, and Perceptual Error. Comparison of the findings to previous research finds both similarities and contrasts. Recommendations for preventing accidents are provided.

PY - 2011/12//Final Report
SP - 28p
AB - Thirty delegates, mostly from the FAA’s Aviation Safety (AVS) business unit, but also from U.S. industry and Transport Canada, assembled for a two-day workshop in Oklahoma City, OK. The workshop format combined key presentation topics, each followed by structured discussion. Following the discussion, the delegates generated a rank-order listing of the most important actions needed to reduce maintenance fatigue risk. Section 2.0 of this report elaborates on the “top ten” actions identified: 1. Enhance Employer and Worker Fatigue Awareness 2. Continue and Expand Fatigue Countermeasure Education 3. Support and Regulate Fatigue Risk Management Systems (FRMS) 4. Quantify Safety and Operational Efficiency Impact of Fatigue 5. Regulate Hours of Service Limits 6. Establish Baseline Data of Fatigue Risk with Existing Event-Reporting Systems 7. Integrate Fatigue Awareness Into Safety Culture 8. Ensure That FRMS is Considered in Safety Management Systems (SMS) Program 9. Create and Implement Fatigue Assessment Tools 10. Improve Collaboration of FRMS Within and Across Organizations The workshop delegates felt that the FAA is addressing many of these challenges, but there is substantial opportunity to increase attention to each topic. Their consensus was to address the challenges not only with research and development but also with operational activity and possible future regulation.

TI - Toxicological Findings in Fatally Injured Pilots of 979 Amateur-Built Aircraft Accidents
PY - 2011/12//Final Report
SP - 18p
AB - Biological samples collected from fatally injured pilots in aviation accidents involving all types of aircraft, including amateur-built aircraft, are submitted to the Civil Aerospace Medical Institute (CAMI) for accident investigation. These samples are analyzed for fire gases, ethanol, and drugs. Trends of amateur-built aircraft accidents and toxicological findings in the associated pilot fatalities have not been examined. Amateur-built aircraft accidents that occurred during 1990–2009 were evaluated by retrieving necessary information from the CAMI toxicology database. Probable cause and factor in the amateur-built aircraft mishaps were obtained from the National Transportation Safety Board's (NTSB's) aviation accident database. Of 6309 aviation accidents from which CAMI received postmortem samples, 979 (16%) were related to amateur-built aircraft. The highest number of aviation mishaps occurred during summer, which was true with amateur-built as well as with all other aircraft. There was a decreasing trend in accidents of non-amateur-built aircraft, whereas there was an increasing trend in accidents of amateur-built aircraft. In the 979 accidents (pilots), 392 were positive for ethanol and/or drugs. Ethanol was found in 29 pilots, drugs in 345, and ethanol plus drugs in 18. For ethanol/drug-related accidents also, a decreasing trend was observed with non-amateur-built aircraft and an increasing trend with amateur-built aircraft. Of the 392 amateur-built aircraft, 388 (99%) were flying under the general aviation category. In the 392 pilots, 238 (61%) held private pilot flying certificates and 260 (66%) third-class airman medical certificates. The spectrum of drugs found in the amateur-built aircraft accident pilot fatalities was consistent with commonly used drugs in the general population. The percentage of pilots wherein prescription drugs were detected was 26% for amateur-built aircraft, whereas it was 16% for non-amateur built aircraft and 18% for all aircraft. Ethanol/drug use and medical condition were determined to be a cause or factor in 42 (11%) of the 385 ethanol/drug-positive amateur-built aircraft accidents investigated by the NTSB. However, the contributory role of the mechanical malfunction of home-built aircraft cannot be ruled out in the observed increasing trends in their accidents, with or without ethanol and/or drugs. The increasing trend of such accidents is of significant concern.

TI - Evaluating Methods for Counting Aircraft Operations at Non-Towered Airports
AB - Aircraft operations counts are used in aviation systems planning, airport master plans, environmental studies, aviation forecasts, as well as to determine funding and design criteria for the nation's airports. At airports with control towers, aircraft operations are tracked and recorded by air traffic control. However, of the more than 5,300 public use airports in the United States, only 546 have towers, and most of the towered airports are not open at all times. This results in airports having to estimate operations counts, which, in the case of non-full-time towers, can result in potential undercounting. Airports, as well as state and metropolitan planning agencies, use various methods to estimate aircraft activity when tower counts are not available. The most common methods have traditionally relied on guest logs, fuel sales, visual observation, automatic counters, and acoustical counters. Airport Cooperative Research Program (ACRP) Synthesis 4: Counting Aircraft Operations at Non-Towered Airports (published in 2007) described the different methods of counting and estimating aircraft operations, and provided an initial recommendation for best practices. The study, however, was completed prior to recent advances in technology (such as the use of video data capturing devices) and, due to its limited scope, did not include a program to test the different methods. Research is needed to identify, test, and evaluate the various methods for obtaining aircraft operations counts at non-towered airports. This should be done in a manner that will help airports select the most appropriate method for their needs. The objective of this research is to identify, test, and evaluate methods for obtaining aircraft operations counts at non-towered airports.

TI - Analysis of Suppression Effects on Aviation Fuel Fires Around an Aircraft
PY - 2011/11//Final Report
SP - 99p
AB - This report describes the details of a theoretical analysis of the firefighting agent amounts carried by aircraft rescue and firefighting (ARFF) equipment. The report is a detailed heat transfer and suppression analysis of fuel spill fires on exposed aircraft. This analysis addressed various factors in assessing current ARFF agent requirements. The amount of firefighting agent necessary to prevent interior aircraft ignition and allow for safe egress is presented for representative fuel spill fire scenarios and ARFF arrival times. The scenarios consider wind conditions, aircraft and fuel spill sizes, aircraft skin thickness, and aircraft insulation/construction. For example, fires burning in wind conditions will have a different flame shape and flame length than a fire burning under calm conditions with all other parameters held constant. The analysis also found that the time required to melt the aluminum skin is strongly dependent on the exposure heat flux and on the skin thickness but not on the insulation thickness. The evaluation of the firefighting agent amount effect on the success of aircraft egress for a given fire scenario must address a number of elements, such as fire effects on egress, ARFF effects on the fire through the agent amount carried, and the relevant fire scenario parameters for the fire, aircraft, and passengers.

Fitment of Automatically
Disposable Hatches at Type III
Exits With Regard to the Number
of Certificated Passenger Seats
PY - 2011/11//Final Report
SP - 15p
AB - This study was commissioned by Transport Canada (TC) in support of a cooperative regulatory activity between itself, the European Aviation Safety Agency (EASA), and the United States Federal Aviation Administration (FAA) regarding Type III exit access and ease of operation. EASA has formulated a Notice of Proposed Amendment (NPA) and Regulatory Impact Assessment (RIA) under the auspices of a Rulemaking Group (CS 25.040) comprising representatives from TC and the FAA and from aircraft operators, aircraft manufacturers, and cabin crew organizations. The subject NPA proposes that CS-25 be amended to require that airplanes should be configured with Automatically Disposable Hatches (ADHs) at Type III exits and applicability should be to airplanes with a passenger seating capacity of 40 or more. The objective of this report was to address any issues that might affect the selection of 40 passenger seats as the lower limit for installation of ADHs at Type III exits. Therefore, this study considers the safety impact of the proposed regulation should it be applied to airplanes with a passenger seating capacity between 20 and 80. A benefit analysis carried out for ADHs at Type III exits suggests that the life-saving potential for airplanes with a passenger seating capacity of less than 40 is small compared to larger airplanes. A review of the CAR 525/CS-25/14 CFR 25 exit requirements pertinent to airplanes certificated with a passenger seating capacity between 20 and 80 suggests that evacuation capability increases as passenger complement decreases, and that enhancements to evacuation capability are not warranted for airplanes with a passenger seating capacity of less than 40.

TI - Test and Evaluation of Next Generation 65-Foot, High-Reach Extendable Turret
PY - 2011/11//Final Report
SP - 81p
AB - Since the introduction of the High-Reach Extendable Turret (HRET) to the Aircraft Rescue and Firefighting (ARFF) industry, approximately 400 HRET, have been retrofitted into existing ARFF vehicles or purchased with new ARFF vehicles worldwide. Some advantages and benefits of this technology include increased throw range performance, increased range of turret motion, more efficient agent application by applying agent at the seat of the fire, faster extinguishment of two-dimensional pool and three-dimensional flowing fuel fires, and the ability to penetrate inside an aircraft to cool the interior cabin and extinguish the fire. This added capability can increase passenger survivability, protect property, and extinguish fire faster during an aircraft postcrash incident. The purpose of this research was to document the effects of the installation of the 65-ft HRET on the predelivery inspection test of the Federal Aviation Administration (FAA) Striker ARFF research vehicle (FAA Striker). The second key objective was to evaluate the performance and firefighting effectiveness of the 65-ft HRET in and around new large aircraft, such as the Airbus A380 and the Boeing 747-8. The results of test were as follows: 1. The FAA Striker, in both the baseline configuration and with the 65-ft HRET installed, passed all vehicle performance checks, with the exception of the weight distribution and body and chassis flexibility tests. For the weight distribution test, the baseline vehicle exceeded the maximum difference between axles by 1%, and the vehicle with the HRET installed exceeded the maximum difference between axles by 1.6%. For the body and chassis flexibility test, the baseline vehicle failed the tire height requirement by 8 in., and the vehicle with the HRET installed failed the tire height requirement by 4 in. 2. From a bedded position, using the HRET, penetration and agent discharge into the lower passenger deck of an A380 mockup occurred in 54 seconds, into the upper passenger deck in 62 seconds, and into the cargo level in 80 seconds. 3. The FAA Striker and the HRET were reliable and required only a few repairs throughout the course of the tests, which included hundreds of operations and tests. The only component of that failed repeatedly was the hydraulic gearbox on the HRET. The findings of this research support the removal of the base turret from the design and increasing the flow rate of the tip nozzle to a selectable low/high flow rate of 500 and 1000 gallons.

TI - Evaluation of a Fatigue Countermeasures Training Program for Flight Attendants
PY - 2011/11//Final Report
SP - 18p
AB - There is a growing population of employees that work non-traditional hours in around-the-clock operations. Cabin crew/flight attendants are part of this population and work highly variable schedules that include extended duty days, time zone changes, night schedules, and on-demand calls. These schedules conflict with the body’s natural mechanisms for managing sleep and alertness, and often result in fatigue. Fatigue countermeasure training may be necessary for the health, well-being, and safety of workers. The current research evaluated a comprehensive fatigue countermeasure training program for flight attendants using a theoretically grounded taxonomy of training criteria. Alternative evaluation strategies were also utilized to improve traditional pretest– posttest designs and provide convergent evidence of training effectiveness.

TI - Development of an Airport Ground Vehicle Runway Incursion Warning System
PY - 2011/10//Final Report
SP - 40p
AB - The Federal Aviation Administration continues to assess ways to prevent runway incursions and other airport operational incursions, especially during ground vehicle operations at airports. The minimum operational performance specifications described in this report identify a stand-alone incursion warning system for a ground vehicle driver. A global positioning system (GPS) was used to provide vehicle location information for this warning system. The objectives of this research were to evaluate current navigation devices for use in airport ground vehicles to prevent airport incursions, provide recommendation criteria for the design and operation of a system defining both minimum performance and optimal features, and provide cost estimates for the procurement of equipment. The two types of devices that were evaluated could be modified and used as an airport ground vehicle runway incursion warning system to prevent runway incursions. The first device demonstrated a preconfigured system that functions without additional modifications for all airports. The second device was a custom system with software and hardware components that can be modified to the airport user’s needs. Based on this report, minimum performance criteria for an airport ground vehicle incursion warning system were established. Minimum performance criteria included the vehicle location accuracy equal to a wide area augmentation system GPS accuracy of <3 meters 95% of the time, location receiver placement on a vehicle, proximity warnings, alert areas, audible and visual signals to the driver, system updates, and compliance. An airport ground vehicle runway incursion warning system should not give directions for navigating on an airport, and must not take the place of airport familiarization and air traffic control instructions. The system should be used as a situational awareness tool. Optional features that were not critical to preventing a runway incursion but would provide additional benefits to airport users are discussed in this report. Cost estimates for the preconfigured system ranged from $1500 to $2000. The cost for the custom system depended on the requirements specified by the airport user. A single, independently operated device ranged from $2000 to $4000. If an airport user requested a network infrastructure to take full advantage of the custom system’s capabilities, the cost reached upwards of $100,000.

TI - Development of Criteria for Using the Superpave Gyratory Compactor to Design Airport Asphalt Pavement Mixtures
PY - 2011/10//Final Report
SP - 247p
AB - Asphalt mix design for commercial airports in the United States is performed in accordance with guidelines set forth in the Federal Aviation Administration (FAA) Advisory Circular AC 150/5370-10D, “Standard for Specifying Construction of Airports, Item P-401—Plant Mix Bituminous Pavements.” Currently, two methods are used to compact asphalt pavement mixtures used in transportation surfaces. The Marshall method, the standard method for commercial airports, uses an impact device that imparts a repetitive stress to the mixture. The Superpave design method provides a kneading action to compact the mixture under constant strain conditions. Design of asphalt mixtures for airfields has been successfully accomplished using the Marshall method since the 1940s. The Superpave design method was developed and adopted by state departments of transportation beginning in the mid-1990s. Currently, most transportation departments have adopted this concept. Since most of the paving work by the asphalt industry is funded by state departments of transportation and private work (which typically use department of transportation criteria), it is becoming more difficult to find laboratories and contractors that continue to use the Marshall method. Hence, it is important that the Superpave method be adopted for airfield pavements. Prior to adopting Superpave as the primary method, it was necessary to determine the number of gyrations required to provide an adequate compactive effort for airfield pavements. This study evaluated the number of gyrations for a number of mixtures required to provide a density equal to 75 blows with the Marshall hammer. Since the 75-blow Marshall mixtures had performed well in the past, it was believed that providing a density with the gyratory compactor equal to that obtained with Marshall compaction would be a good way to adopt Superpave and still have confidence of good performance. This report describes the details of the study and provides a recommended number of gyrations with the Superpave gyratory compactor to provide a mixture that will perform similar to the 75-blow Marshall mixture. The study recommended that 70 gyrations are required to produce a mix similar to the 75-blow Marshall mixture. Additional research is also needed to correlate field performance of asphalt mixtures designed using Superpave methodologies.

TI - Analysis of Citalopram and Desmethylcitalopram in Postmortem Fluids and Tissues Using Liquid
Chromatography-Mass Spectrometry
PY - 2011/10//Final Report
SP - 16p
AB - Citalopram is a selective serotonin reuptake inhibitor that is a commonly prescribed drug for the treatment of depression, obsessive-compulsive disorder, panic disorder, anxiety disorder, and post-traumatic stress disorder. While the use of citalopram is relatively safe, certain side effects could negatively affect a pilot’s performance and become a factor in an aviation accident. The side effects of this medication include nausea, tiredness, drowsiness, dizziness, and blurred vision. Due to the severity of aviation accidents, blood samples are often not available, so tissues must be relied upon for analysis. Therefore, understanding the distribution of a drug throughout postmortem fluids and tissues is important when trying to interpret drug impairment and/or intoxication. Our laboratory investigated the distribution of citalopram and its main active metabolite, desmethylcitalopram, in various postmortem tissues and fluids obtained from 15 fatal aviation accident cases. When available, 10 specimen types were analyzed for each case, including blood, urine, vitreous humor, liver, lung, kidney, spleen, muscle, heart, and brain. Whole blood citalopram concentrations obtained from these 15 cases ranged from 0.079 to 1.06 μg/mL. Distribution, expressed as specimen/blood ratio, for citalopram was 12 ± 19 in urine, 0.42 ± 0.21 in vitreous humor, 16 ± 8 in liver, 15 ± 15 in lung, 3.6 ± 2.5 in kidney, 8.1 ± 3.7 in spleen, 0.83 ± 0.40 in muscle, 2.3 ± 1.2 in brain, and 1.9 ± 1.0 in heart. Distribution coefficients obtained for citalopram had coefficient of variations (CV) ranging from 46-158%. With such large CV’s, the distribution coefficients have very little use in aiding in the interpretation of citalopram-positive tissue specimens. Furthermore, no consistent citalopram/desmethylcitalopram ratio was identified within any specimen group. This study suggests that citalopram likely undergoes postmortem concentration changes.

TI - Flight Attendant Fatigue: A Quantitative Review of Flight Attendant Comments
PY - 2011/10//Final Report
SP - 26p
AB - Today’s aviation industry is a 24/7 operation that produces a variety of challenges for cabin crew members including extended duty periods, highly variable schedules, frequent time zone changes, and increased passenger loads. The present content analysis study was conducted to provide a quantitative review of flight attendant comments provided on the congressionally mandated survey of flight attendant field operations that was conducted in 2008. This report can be used as a supplement to interpret the published survey results (Avers et al., 2009b). Two hundred surveys were randomly selected for each type of operation and level of seniority. A total of 1,800 surveys with comments were content analyzed (936 paper, 864 online). Eight broad comment categories were identified, including: scheduling, health, airline and airline policy, job performance and satisfaction, meals, survey, workload, and break facilities. Each category consisted of multiple positive and negative issues identified by flight attendants. This report outlines the most frequently reported categories and issues, summarizes the key issues by type of operation (low-cost, regional, network carrier) and seniority level (junior – bottom one-third, mid – middle one-third, senior – top one-third), and provides examples of actual respondent comments for the most commonly identified topics.

TI - Research Methods for Understanding Aircraft Noise Annoyance and Sleep Disturbance
AB - Community exposure to aircraft noise has historically led to public opposition against airport activity and development. The seminal work by Schultz published in 1978 developed a correlation (exposure-response relationship) between transportation noise exposure levels in terms of the day-night average noise level (DNL) and the percentage of the population highly annoyed by that noise using social surveys, the most commonly accepted means of measuring annoyance. Schultz' work was reaffirmed by the Federal Interagency Committee on Noise (FICON) in 1992. Since then, research in the United States on the effects of aircraft noise has lagged, while aircraft noise has continued to evolve with substantial increases in traffic volume and significant improvements in noise levels of single aircraft. It is therefore unclear whether an exposure-response relationship based on currently available data is sufficiently representative for U.S. airports today. Aircraft noise may also disturb sleep. Developing a relationship between the degree of sleep disturbance and the level of noise exposure is a prerequisite for identifying and protecting communities from adverse noise effects. There is currently no widely accepted exposure-response relationship for sleep disturbance. Establishing up-to-date exposure-response relationships for community annoyance and sleep disturbance in the U.S. requires an extensive data acquisition campaign covering a wide variety of airport types and geographic locations, which in turn requires a well-designed study. Research is needed to develop a protocol for conducting large-scale social surveys to acquire data for understanding noise exposure-annoyance relationships and to develop methods to better understand the effects of aircraft noise on sleep. The objectives of this research are to (1) develop and validate a research protocol for a large-scale study of aircraft noise exposure-annoyance response relationships across the U.S. and (2) propose alternative research methods for field studies to assess the relationship between aircraft noise and sleep disturbance for U.S. airports. Accomplishment of the project objectives will be conducted in three phases. Phase I will cover the aircraft noise exposure-annoyance response research; Phase II will cover the aircraft noise and sleep disturbance research; and Phase III will consist of final report preparation.

TI - Low Power/Low Drag Approaches to Mitigate Environmental Impacts of Aviation
AB - Concerns about the aviation's environmental impact have prompted research efforts around the world. Much of this research has focused on changes to future aircraft and engine designs: although these hold the prospect of significant environmental impact reductions on a per flight basis, it will take a long time for them to be developed and propagate through the operational fleet in sufficient numbers to have a significant impact on overall emission levels. Until then, strategies that reduce the environmental impacts of existing aircraft are needed. Therefore, there is a need to identify and evaluate ways to reduce the environmental impacts of aviation in the near term. Such changes would involve minor adjustments to operating procedures or limited equipment/infrastructure changes. The goal of Project 32 was to systematically evaluate and rank all the potential near-term operational changes against a common set of environmental impact and feasibility criteria, and hence make it possible to determine the relative potential of the various options and to understand which ones should be given priority.

TI - Performance Assessment of a Mobile, Radar-Based Foreign Object Debris Detection System
PY - 2011/09//Final Report
SP - 35p
AB - In 2008, the Federal Aviation Administration (FAA) Airport Technology Research and Development Team initiated research to conduct a performance assessment of the Trex Enterprises FOD Finder™, a mobile, radar-based foreign object debris (FOD) detection system. This assessment included the system’s capability to detect objects of various shapes, sizes, and materials at all locations on the runway surface. The system’s capability to detect FOD during both nighttime and daytime conditions, in periods of sun, rain, mist, fog, and snow was also assessed. The FOD Finder detection system was installed at the Chicago O’Hare International Airport (ORD) in March 2009 and initially tested in July 2009. The assessment of the FOD Finder detection system at ORD was supplemented by the evaluation of two additional FOD Finder detection systems at Honolulu International Airport and the McClellan-Palomar Airport in Carlsbad, California. The performance assessment at all three airports began in May 2010 and concluded in September 2010. Researchers conducted several test sessions at each airport to assess the FOD Finder’s capability to detect selected FOD items that were of various shapes, sizes, color, and material in both nighttime and daytime conditions, in periods of sun, rain, mist, fog and snow. The FOD Finder detection system was able to detect the objects of various shapes, sizes, and materials on runway surfaces, taxiways, and aprons, and was able to perform satisfactorily in nighttime, daytime, sun, rain, mist, fog, and snow conditions, as required by FAA Advisory Circular 150/5220-24, “Airport Foreign Object Debris (FOD) Detection Equipment.”

TI - Flying Blind: Aeromedical Certification and Undiagnosed Age-Related Macular Degeneration
PY - 2011/09//Final Report
SP - 14p
AB - Background: The love of flying seldom diminishes throughout a pilot’s career. It is often the primary motivation for investing the time and expense necessary to attain and maintain a valid pilot license and medical certificate. However, a pilot’s ability to meet the physical requirements for aeromedical certification may become compromised by advancing age or impairments. Individuals with physical limitations or the elderly in a number of states must pass a vision test to renew their driver’s license. These individuals may resort to extraordinary measures to avoid losing the privilege of operating a motor vehicle and maintain a sense of independence. Similarly, pilots with physical limitations may attempt to circumvent the Federal Aviation Administration’s aeromedical certification process in order to retain a valid medical certificate. Case Report: In an investigation of a fatal accident the National Transportation Safety Board (NTSB) concluded that the aviation medical examiner who issued an airman medical certificate to a visually impaired pilot failed to perform the appropriate procedures to verify the validity of medical information provided by the pilot. The airman subsequently crashed his aircraft, resulting in his death and the deaths of five others onboard. Conclusions: The NTSB report stated the pilot's “failure to maintain airplane control for an undetermined reason resulted in an inadvertent stall.” The report also stated that “either the pilot's macular degeneration or his unrecognized coronary artery disease could have contributed to his failure to maintain control of the airplane.” The potential debilitating effects associated with these and other serious health issues are discussed.

TI - The Line Operations Safety Audit Program: Transitioning From Flight Operations to Maintenance and Ramp Operations
PY - 2011/09//Final Report
SP - 20p
AB - Managing risk has become increasingly important in modern organizations, including medicine, aviation, and finance. Accident investigation concentrates on failures, which are important for discovering major breakdowns, but failures are rare events. Proactive approaches offer the flexibility of observing normal operations. A Line Operations Safety Audit (LOSA) is a voluntary safety program that collects safety data during normal airline operations and was originally designed for flight deck operations. The goal of this FAA-sponsored project is to capitalize on the 10-plus years of successful audits on the flight deck. The hazards that threaten the safety of flight deck operations are not unique to that environment. Similar problems are present during maintenance and ramp operations. This report provides a review of the use of LOSA, discusses LOSA’s essential operating characteristics, lessons learned on the flight deck, and describes the extension of LOSA to maintenance and ramp operations. The research team developed tools for airlines and maintenance organizations to use as they initiate their maintenance (M-LOSA) and ramp (R-LOSA) programs.

TI - Drugs and Alcohol in Civil Aviation Accident Pilot Fatalities From 2004-2008
PY - 2011/09//Final Report
SP - 20p
AB - The Federal Aviation Administration (FAA) Office of Aerospace Medicine sets medical standards needed to protect the public and pilots from death or injury due to incapacitation of the pilot. As a part of this process, toxicology testing is performed by the FAA on almost every pilot who is fatally injured in an aviation accident to determine the medical condition of the pilot, medications used by the pilot at the time of the accident, and the extent of impairment, if any. The data were extracted from the FAA toxicology database for all fatal pilots who died from 2004 and 2008 in aviation accidents. The laboratory received and tested specimens from 1353 pilots who died in aviation accidents between 2004 and 2008. Findings where classified into three separate categories: Controlled Dangerous Substance, Prescription, and Over-the-Counter drugs. This study was conducted to determine the extent of drug use in pilots who have died in an aviation accidents from 2004 to 2008 and to determine the types of drugs most commonly found. A comparison of previously published reports with this study’s report was made to determine trends in drug use by pilots who have died in aviation accidents over the past 20 years. Factors were examined that could influence drug trends noted over the years. Diphenhydramine, an H1 antihistamine with impairing properties, is the most common drug found in pilots who have died in aviation accidents. The FAA has taken steps to warn pilots of the dangers in using this medication that is dispensed as both a prescription and an over-the-counter medication. Because significant aviation performance impairment can be associated with diphenhydramine, the Office of Aerospace Medicine will continue to take steps to help pilots decide when it is safe to resume flying duties after taking such an impairing medication.

TI - Development of a Ten Year Emerging Metallic Structures Technology (EMST) R&D Roadmap
AB - The objective of the project will be to address certification and continued airworthiness issues arising from the use of emerging metallic materials and construction methods (new aluminum alloys--e.g., aluminum lithium; new production processes--e.g., friction stir welding; advanced metallic hybrids, Glare, bonded structure) increasingly being used for aircraft structures by development of a 10 year roadmap for the research and development required to assure future airworthiness of these advanced structural materials. This proposal will provide the Federal Aviation Administration (FAA) with data collected from various sources to understand the durability and damage tolerance performance of these emerging technologies, and determine the applicability of existing regulations and regulatory guidance material. The approach of this proposal will be to outline a roadmap to leverage existing FAA resources with those of industry, to ensure safe implementation of emerging technologies in aircraft products.

TI - Development of Technologies to Improve the Reliability and Intelligence of Aircraft Electrical Wire and Interconnect Systems
AB - To improve the reliability and intelligence of aircraft power systems, there is a need for inexpensive, lightweight sensors that can be incorporated into aircraft electrical wiring interconnection system (EWIS) to ensure proper clamp installation as well as detect clamp malfunction and secondary damage mechanisms of any unsupported wires. During previous Federal Aviation Administration (FAA) funded research, different SMART (Status and Motion Activated Radio frequency Tag) sensor concepts based on a reversibly deactivated/activated radio frequency identification tag were developed. Additional SMART sensors capable of aiding maintenance personnel in the identification of degraded connectors would provide further improvement in EWIS performance. Therefore, the University of Dayton Research Institute proposes to conduct a 12 month period of performance research projects consisting of ten main tasks to design, develop, manufacture, then evaluate different candidate SMART sensors for incorporation into current and future aircraft EWIS.

TI - Understanding Airline and Passenger Choice in Regions with Multiple Airports
AB - Improving, expanding, and retaining commercial air service and attracting more passengers are goals for many airports. In multi-airport regions, these efforts are complicated by the fact that airlines and passengers have the additional choices made available by the other airports in the system. Air carrier service decisions are based on profitability, network/fleet considerations, competition, and perceptions of consumer behavior. Passengers select a particular airport based on air service schedule and reliability, airfare, accessibility, total travel time, and other factors. Airports that use promotional campaigns, air service studies, air service subsidies, and facility improvements to attract more air service and passengers may experience disappointing results if they do not understand the unique dynamics of a multi-airport region. In addition, there are many types of multi-airport systems. Some systems serve a metropolitan area while others serve an entire region or state. Some have a dominant airport, while others have airports with similar levels of activity. Some systems have airports operated by a single entity, while in other systems, each airport is under separate control. Research is needed to help airports and their stakeholders understand the dynamics of airline and passenger decision making in multi-airport regions. This research will ultimately help set realistic air service and passenger activity expectations, which, in turn, will help focus limited resources on improving, expanding, and retaining commercial air service. The objective of this research is to assist airports and their stakeholders to better understand the factors that drive airline service decisions and passenger choice in multi-airport regions.

TI - Best Practices for Working in or Near Airport Movement Areas
AB - Airport operators are challenged by the competing interests of safely conducting activities in the airport movement areas while minimizing impacts on flight operations. Personnel find that it's difficult to access airport movement areas to conduct maintenance, operations, and construction activities due to a variety of reasons. Airport operators have adopted their own practices for dealing with these day-to-day challenges. As such, research is needed to identify best practices for working in or near airport movement areas. The objectives of this research are to (1) identify best practices for working in or near airport movement areas and (2) develop tools, techniques, and training aids that can be used by airport operators to train their personnel, tenants, and contractors on the best practices.

TI - Studies of Next Generation Air Traffic Control Specialists: Why Be an Air Traffic Controller?
PY - 2011/08//Final Report
SP - 16p
AB - With phrases such as “Managing Millennials” (Gimbel, 2007), descriptions of generational differences are a staple in the human resources (HR) trade press and corporate training. The Federal Aviation Administration (FAA) offers a course in managing generational differences through its Center for Management Education and Leadership. Most management tips and descriptions of generational differences are anecdotal, prescriptive and impressionistic. Few empirical studies are available, and those that do exist are based on cross-sectional surveys, confounding the effects of age and career progression with generational differences. Yet the generational comparisons could be important to occupational recruitment; what appealed to one generation might not appeal to another. For example, the job security and stability that appealed to “Baby Boomers” might be less important to “Gen-X” and “Millennials,” who are said to be looking to “make a difference” with some level of “work-family balance” (Partnership for Public Service, 2009, undated). The purpose of the current study was to compare the factors influencing occupational choice in two distinct generations of employees in the FAA’s highly visible air traffic control specialist (ATCS) occupation. The authors hypothesized that factors such as job security, benefits, and pay would be less important to the “Next Generation” of controllers, recruited from Gen-X and Millennials, than to the “Post-Strike” generation (largely Baby Boomers) and non-material factors such as the opportunity to benefit others would be more important to the Next Generation of controllers. Method. The responses of controllers hired in Fiscal Year (FY) 2009 (n=955) were compared to those of controllers hired in FY1986 through FY1992 (n=13,227) following the 1981 Professional Air Traffic Controllers Organization (PATCO) strike. The two groups did not overlap in age or birth year. The new controllers in both generations took the Biographical Questionnaire (BQ) for research purposes while at the FAA Academy for initial occupational training. The BQ includes 14 items asking to what degree material factors such as pay and non-material factors such as the opportunity to benefit others were important to their choice of the controller occupation. The proportions favorably endorsing each factor were compared with a standard Z-test of proportions. The rank-order of the factors in each generation was also compared using Spearman’s rho. Results. Contrary to the authors' hypothesis, job security, benefits, and pay were more important to Next Generation than to Post-Strike controllers. However, the overall rank-order correlation of the factors by generation was high (Spearman’s rho =.824, p < .001), suggesting a shift in degree rather than one of kind between generations. Discussion. The young Next Generation controllers hired by the FAA did not conform to the public stereotype; job security, benefits, and pay were just as important to them, if not more, than to the previous generation. This might be an effect of economic insecurity engendered by the 2007-2010 financial crisis in the U.S. The similar rank-ordering of factors influencing occupational choice suggests more similarity between generations than might be expected on the basis of the HR trade press. Implications for agency recruitment are considered in closing.

PY - 2011/08//Final Report
SP - 23p
AB - Thirty delegates, mostly from the Federal Aviation Administration’s Office of Aviation Safety, but also from the U.S. aviation industry, the National Transportation Safety Board, and Transport Canada, assembled for two days at the Civil Aerospace Medical Institute in Oklahoma City. These leaders in maintenance human factors research met to discuss challenges and prioritize solutions for human factors issues in aviation maintenance. The delegates reviewed international incidents and accidents and corporate operating procedures to identify systematic human factor precursors to maintenance errors. Each human factor issue was discussed and subsequently prioritized by each delegate. Analysis of the data revealed eight core issues, including: use of technical publications, fatigue/alertness, safety culture, event data collection, return on investment for human factors, prioritization of human factors, professionalism and generational issues, and attention to required inspection items. Solutions and action items for each of these issues were discussed and recommendations were developed. The prioritized list of problems and suggested industry actions are detailed in the following report. The recommendations stemming from this report can be used to inform future research and development for maintenance human factors.

TI - Creating a Collaborative Environment Between Airport Operations and Maintenance Departments
AB - Operations and maintenance departments at airports must rely on each other to ensure a safe, secure, and efficient operation of an airport. Yet while operations and maintenance departments need to work together, they don't necessarily have a clear understanding of each other's responsibilities, which can sometimes lead to counterproductive working relationships. While FAR Part 139 can help define work priorities at an airport, there are a myriad of other activities that dictate how and when work will get done from preventive maintenance to repairs to emergency response. Many factors can influence work relationships. As an example, airport organizational structures may have operations and maintenance reporting to different people, leading to competing priorities for day-to-day responsibilities; this may not be conducive to creating a collaborative environment. Therefore, research is needed to identify strategies that airport management can use to foster a collaborative environment between operations and maintenance departments. The objective of this research is to develop guidance for airports to create a collaborative environment between operations and maintenance departments. This guidance should include (1) tools to help airports recognize issues that are counterproductive to collaborative environments, (2) strategies and recommendations to create a collaborative environment between airport operations and maintenance departments, (3) benefits and risks of strategies and recommendations, and (4) a list of relevant resources.

TI - Integrating Community Emergency Response Teams at Airports (A-CERTs)
AB - Community Emergency Response Teams (CERTs) have been developed in many communities to help respond to disasters and emergencies that overwhelm first responders. There are minimum training standards as outlined by the Federal Emergency Management Agency (FEMA) under their Citizens Corp program, however, each community utilizes their CERT volunteers as they deem the most appropriate and provide additional training as applicable. Airports of all sizes also can quickly become overwhelmed in a natural disaster or aircraft incident where their community members want to provide assistance. Smaller airports tend to have limited staff but, just like larger airports, can become the focal point within their community in a disaster recovery plan. Volunteers can be a valuable resource to an airport. However, it is not the time during a disaster or emergency to determine the qualifications, provide training, and obtain necessary security checks to enlist or utilize volunteers to assist. While there are established CERTs within many communities, including some with airports, there is research needed to help airports develop and integrate CERTs in their emergency response planning. The objective of this research is to develop a model CERT program for the airport community that includes (1) an awareness plan and description of benefits, (2) implementation guidance, and (3) steps for integrating into airport emergency response planning

TI - Procuring and Managing Professional Services for Airports
AB - Most U.S. airport owners engage professional service firms to assist them with the planning, design, and management of capital development projects and other professional services at their facilities. Such firms bring resources, specialized technical capabilities, and subject matter expertise needed for these activities that may not be available within the airport owners' organization. While some resources exist that include best practices for certain elements of procuring professional services, there is no comprehensive resource that provides recommended practices that can guide an airport from the initial stages of procuring services through to completion. Such a resource would provide well-documented and practical steps that could improve the contractor selection process and engagement of the firm through completion, resulting in successful and high-quality services. The objective of this research is to develop a handbook that provides guidance for procuring and managing professional services at airports for use by airport owners and operators. For this research, professional services should include, but not be limited to, planning, environmental, architectural & engineering, information technology, construction, financial, legal, and other key professional services provided to airports. The handbook should cover (a) the procurement process, including scoping, pre-selection process, selection criteria, evaluation and contract negotiations; and (b) processes for managing professional services contracts. The handbook should consider all sizes and types of airports and key professional services.

TI - Understanding Microbial Biofilms in Receiving Waters Impacted by Airport Deicing Activities
AB - As the more significant environmental impacts of deicing activities are mitigated by runoff controls, increasing scrutiny is being directed toward other issues, including the occurrence of microbial slime at stormwater outfalls. The challenge to the aviation community for addressing this issue is significant, because microbial growth associated with deicing discharges is not currently predictable, the controlling factors are poorly understood, and the costs of treatment controls are substantial. For example, "sewer bacteria" such as Sphaerotilus natans (a filamentous bacterium associated with organic-rich wastewater discharges), appear to be ubiquitous in the environment, and may flourish wherever the right conditions exist. This situation presents a high level of risk associated with the large investments needed for controls that may or may not eliminate the microbial growths. Airports need reliable information on what is and is not known about the factors contributing to the occurrence of nuisance microbes and the options for controlling them. Environmental regulators would also benefit from this information as they consider potential requirements. The objectives of this research are to: (1) provide airports and regulatory agencies with a reference document that summarizes what is currently known and not known about the occurrence of nuisance microbial communities in receiving waters in the vicinity of airports; (2) identify the interrelationships among the environmental parameters controlling their growth; and (3) produce a detailed work plan listing the steps needed to address knowledge gaps and to prepare a guidebook providing practical mitigation alternatives for managing nuisance microbial communities.

TI - Legal Aspects of Airport Programs. Topic 04-01. Airport Liability for Wildlife Management
AB - The safety of airport users is of paramount importance. At the same time, airports are subject to a variety of federal and state laws and regulations aimed at protecting wildlife. ACRP Report 32 "Guidebook for Addressing Aircraft/Wildlife Hazards at General Aviation Airports" provides additional background material on these regulations. These mandates must be taken into account in the development of procedures to minimize the potential hazards to aircraft created by wildlife. This project will identify applicable laws and regulations that impact airports' responses to on-airport wildlife and concern off-airport land uses compatible with aircraft operations (e.g., discouraging land uses that attract birds). This project will also identify legally acceptable means airports can pursue to remove or discourage wildlife, including protected species, from runways, taxiways, and airspace necessary for takeoffs and landings. One objective of this research is to identify applicable federal and state statutes and regulations, federal grant assurances, and Federal Aviation Administration (FAA) directives and advisory documents that apply to airport protection of wildlife on-airport or promotion of compatible land use off-airport. The report should also identify those federal and state entities that regulate an airport's management of wildlife. The research team will be submitting the Task 3 report early 2012.

TI - Enhancing the Airport-Industry SAGA Website
AB - There is increased attention and interest toward sustainable practices and incorporating them into airport planning, construction, and everyday operations. Many airport operators have made commitments to be more sustainable through a variety of mechanisms, including policy statements, adoption of goals, measuring and reporting, and development of airport-specific sustainability guidelines. Airports have implemented myriad sustainable practices focused on improving their environmental, economic, and social viability. Many airports, however, do not have the staff expertise or resources available to look for and learn about the sustainable practices that may be applicable at their airport. To assist airport operators looking to undertake a sustainability program or incorporate sustainable practices into their projects and operations, Airports Council International-North America, the Airport Consultants Council, the American Association of Airport Executives, the Air Transport Association, and the Federal Aviation Administration established the Sustainable Aviation Guidance Alliance (SAGA) in late 2008. SAGA collected information on hundreds of airport sustainability initiatives that have been employed by airports across the United States, Canada, and internationally and used that information to develop a comprehensive searchable database and accompanying guidance document that can assist airport operators in planning, implementing, and maintaining sustainability programs. The SAGA database was launched in October 2009 and is now available online at www.airportsustainability.org. The current database provides a good resource for airports looking to improve their sustainability. However, because SAGA has been a purely volunteer effort of association, airport, and consultant experts in sustainability, the resources are not available to provide additional supporting information that could make the database of practices a more valuable tool. The database provides a list of hundreds of sustainable practices, but little supporting material or resources to consult for additional information. As an example, one practice included is "Develop an Energy Master Plan for the organization's facilities." The database would prove more useful if it also described what an energy master plan entails; the associated costs/benefits; and links, cites, or contacts for additional information. The objectives of this research are to: (1) improve and enhance the SAGA website and (2) provide recommendations for maintaining and updating the SAGA website and its sustainable practices contents over time. Improvements and enhancement to the SAGA website should include updating existing sustainable practices data--including new practices--and identifying, vetting, and populating additional supporting information for each of the sustainable practices provided.

TI - Integrating Web-Based Emergency Management Collaboration Tools into Airport Operations: A Primer
AB - Various in-house and Commercial Off The Shelf (COTS) software and web-based collaboration, communication and control systems are being utilized as emergency management tools by municipalities and airports. Tools such as "WebEOC," "E Team," and others are used to coordinate between on-scene commanders and emergency operations centers for needed resources. While these web-based collaboration tools have proven useful in emergency management, they may also have applicability at airports for other non-routine activities/operations, such as weather events, diversions, and security incidents. As airport communications and emergency response becomes more sophisticated and the use of technology increases, guidelines are needed to help airports evaluate the benefits and costs of implementing or expanding existing web-based communications and controls systems. Research is needed to help airports and municipalities integrate web-based collaboration tools into their day-to-day and emergency management operations, identify the features and functions appropriate for their unique needs, and implement an effective web-based collaboration tool. The objective of this research is to prepare a guidebook to be used by operations, public safety and security, and information technology staff at airports to evaluate and implement web-based collaboration tools that provide a common operating picture (COP) for both day-to-day operations and full emergency response management. The guidebook will provide the criteria and best management practices for the procurement, design, integration, and operation of a scalable web-based collaboration tool.

TI - Performance of Unbound Layers of a Flexible Pavement System During Aircraft Loading
AB - The objective is to study the compaction characteristics of various aggregate materials used for construction of a flexible pavement system using a combination of laboratory tests and field data available from the National Airport Pavement Test Facility (NAPTF). The laboratory test will be conducted using the Superpave Gyratory Compactor (SGC), which can simulate trafficking conditions. The efficacy of using the SGC as a better tool to predict the performance of these aggregate materials during trafficking will also be confirmed. In addition, the performance degradation of the material due to crushing will also be studied and correlated with performance measures that the Federal Aviation Administration (FAA) uses for quality control of aggregate to study at what level of trafficking the aggregate does not meet quality control standards including shape, angularity, and grain size distribution. In addition, a micro-mechanical framework for characterizing the material behavior of the aggregate will be investigated. The study will contribute to a significant improvement in the design methodology used for design of airport pavements and provide a better understanding of the performance of pavement systems especially due to heavy aircraft loads with complex gear configuration.

Finally, the researchers intend to investigate a prototype model for multiple flight trajectory optimization, by considering standard optimization approaches for a limited set of multiple flights over one sector of airspace. They extend the work to cover a sector with flights and determine efficient optimization approaches. The sector and the flights, procedures for 4-D trajectories, and other factors will be considered in collaboration with the Federal Aviation Administration (FAA).

TI - Guidelines for Air Cargo Facility Planning and Development
AB - Air cargo is a significant component of the world's manufacturing and retail supply distribution chain in general and an important revenue source for the airport industry in particular. As a result, making long-term investment decisions regarding air cargo facilities at our nation's airports is exceedingly important; however, these decisions can often be difficult given the complex and dynamic nature of the business of air cargo. Over time, these complexities have grown as a function of modal shift, airport access, regulatory and security compliance issues, changing economic conditions, increased sensitivity to environmental issues, changing aircraft configurations and size, and other challenges. What often complicates the issue is that many airports use antiquated air cargo facilities that no longer meet demand or service requirements, nor accommodate changes to cargo handling procedures and evolving security requirements. As airports develop, redevelop, expand, and modernize their cargo facilities, they are finding incomplete and inconsistent air cargo activity data as well as a lack of generally accepted air cargo planning standards and design guidelines. For example, some carriers include trucked tonnage in monthly reports while others do not. Variations in reporting can affect how airports plan for and allocate space for priority on-airport cargo activity that must consider many factors: facility throughput area, storage/sorting space, aircraft parking, cargo tug lanes, ground handling equipment storage areas, landside truck docks, and overall traffic circulation. Given this complex environment, airport management requires current and accurate information coupled with effective planning and development guidelines to ensure that future airport cargo needs will be accommodated. The objective of this research is to develop guidelines for air cargo facility planning and development at airports, including collection of necessary data in support of this effort. These guidelines should assist airport operators in crafting effective business policies and development decisions that meet the industry's current and future technological, operational, and security challenges in a cost-effective, efficient, and environmentally compatible manner. They should also include updated metrics to help guide the overall air cargo development planning process. The potential beneficiaries of these guidelines would include airport owners and operators, airlines, integrated cargo carriers, developers, financial institutions, and others linked to the airport community.

TI - Airport Capital Improvements: Developing a Cost-Estimating Model and Database
AB - Airport capital investment needs are approaching $20 billion dollars annually, based on a 2009 Airports Council International - North America (ACI-NA) capital needs survey. Working to meet this need, individual airports, state and local agencies, and the Federal Aviation Administration (FAA) are dependent on individual case-by-case engineering cost studies and the bid process when estimating, planning, and budgeting for airport capital improvement projects. The engineering, planning, and finance staffs at airports may not always have sufficient project development experience or sufficient information to prepare valid capital cost estimates. In fact, many smaller airports do not have staff to perform these functions and must, as a result, rely on external consulting expertise. In addition, there is insufficient consistency, standardization, and accuracy across the airport industry to compare project cost estimates that result from variations in regional costs, state and local conditions, or levels of technical expertise. Moreover, unique conditions at any given airport make simple comparison with similar projects at other airports often difficult if not problematic. Airports; state, regional, and local agencies; and FAA may not appreciate the options and choices implicit in various designs and their tradeoffs, or have an independent way to benchmark the work of their consultants. Further, airport sponsors need consultants and/or staff that are well versed in current market conditions and emerging innovations. Experience also indicates that increased availability of relevant data can facilitate the capital budgeting process and improve overall project cost estimating, project planning, and implementation, resulting in a more efficient and effective approach to developing an airport capital improvement program. The objective of this research is to develop a user-friendly, interactive, construction cost-estimating model and associated database for airport capital projects along with an implementation guidebook. Projects encompassed by this research should include both airside and landside: (1) airfield, terminal, service and maintenance facilities; (2) runway construction, extension, and rehabilitation; (3) utilities and other infrastructure; (4) security improvements and enhancements; and (5) other airport development projects. The cost-estimating model should be customizable by the user to address standard as well as unique local and regional cost factors. In addition, the model should be able to respond to particular characteristics of airport projects and import readily available commercial construction information databases or services where feasible.

TI - Integrating GIS in Emergency Management at Airports
AB - Geographical information systems (GIS) allow facility and infrastructure owners and operators to integrate information about their assets with mapping software to provide geographical references to other known information about assets to aid their operations. GIS has traditionally been used to support planning, infrastructure development, and management activities. Emergency management-- which consists of prevention, preparation, response, mitigation, and recovery-- involves different agencies, as well as many different public safety and security technologies, such as closed circuit television (CCTV), access control systems, fire and life safety systems, incident management software and web programs, building information management (BIM) systems, and two-way radio communications. Each airport and their mutual aid partners may have different systems that may or may not communicate with each other. GIS could be a productive tool to enhance airport emergency management; however, due to the dependence of airports on their mutual aid partners, the integration and implementation of GIS must be thoughtfully planned and coordinated with them as system requirements and protocols are determined. The Federal Aviation Administration has begun to require airports receiving federal funds to collect aeronautical surveys to standards that include GIS data collection schema. This information to be collected may or may not support a GIS emergency management system. As such, research is needed to help airports understand the capabilities, benefits and challenges of integrating GIS into emergency management as well as how to implement them. The objective of this research is to develop a guidebook for airport operators that will (1) outline the capabilities of GIS with respect to emergency management; (2) examine the benefits, costs, and challenges associated with integrating GIS into emergency management for airports and their mutual aid partners; and (3) provide guidance on implementation and use of GIS to support emergency management.

TI - Assessment of Sound Insulation Treatments
AB - Sound insulation programs have been in existence since the 1980s. They have been successful in improving the quality of life for homeowners and building occupants by reducing aircraft noise levels in those structures. The last 20-30 years has brought on significant improvements in sound insulation materials, treatments, methods, techniques, and lessons learned. In addition, with the passage of time there is a perception by some property owners that those structures that were sound insulated in the early programs are not performing as they once did. There has not been a programmatic approach to evaluate the long-term effectiveness of sound insulation programs including design criteria, materials, and installation standards. As such, research is needed in this area. The objectives of this research are to (1) evaluate the degree and causes of deterioration, if any, in the acoustic performance of homes and buildings that were sound insulated during early sound insulation programs and (2) provide guidance to help airports determine the expectation of the durability and attenuation performance of currently available sound insulation techniques, treatment, and materials that are available today. This research should address, at a minimum, design, installation, materials, and treatments associated with sound insulation programs.

TI - Synthesis of Information Related to Airport Problems. Topic S04-09. Model Mutual Aid Agreements for Airports
AB - Many airport operators enter into emergency management mutual aid agreements with local partners to leverage airport emergency response capabilities. Commercial service airports host aircraft rescue and fire fighting facilities (ARFF) on-airport. Although the ARFF may be the primary responder to an airport emergency, there likely are outside resources that augment ARFF capabilities in case of an aircraft accident or incident, or a disaster effecting airport facilities. Conversely, airports respond to off-airport emergencies for many natural and man-made disasters. Many local emergency management mutual aid agreements are generalized in jurisdiction regulations for emergency response, but many are also written plans and agreements. The objective of this report is to assist airport operators and their local partners in creating and sustaining effective emergency management mutual aid partnerships by synthesizing the specifics of existing agreements that save mutual aid partners time, effort, and money in managing emergencies. The intended audience for this report is airport operations managers and personnel responsible for emergency response and local emergency responders that serve as emergency response partners with airports

TI - Synthesis of Information Related to Airport Problems. Topic S06-04. Adapting New Maintenance Hires to the Airport Environment
AB - Airport managers routinely hire facilitities maintenance personnel who are unfamiliar with the airport operating environment and may not be familiar with the specific systems and equipment at the airport. However, many airports have operating similarities and many core systems in common, such as: (1) New hire familiarization to the airport campus and training on aviation safety and security; (2) The need for personnel to operate independently and safely on the Airport Operators Association (AOA); (3) AOA driver training and air traffic control tower communication protocol; and (4) Physical plant systems-perimeter security, airfield pavements and markings, airfield lighting, fire and life safety, utility plant, terminal systems, access roadways and parking. The objective of this report is to compile a list of core training elements needed for newly hired maintenance personnel to raise their knowledge and understanding of the airport campus, operating environment, and critical infrastructure systems. The intended audience for this report is airport managers at smaller airports who would benefit from having a consistent, comprehensive training syllabus for new maintenance hires.

TI - Evaluating and Mitigating the Risk of Disease Transmission at Airports and on Aircraft
AB - Air travel is often seen as creating an opportunity for the spread of infectious diseases such as influenza, norovirus, and tuberculosis. A 2009 Transportation Research Board (TRB) symposium on the transmission of disease in airports and on aircraft highlighted gaps in using existing research to assess the likelihood that individuals would become infected in the airport and aircraft environment. In addition, the 2009 H1N1 influenza pandemic demonstrated the need for airports and aircraft operators to understand the exposure risk and for guidance to help them develop strategies to more effectively respond to both routine and emerging infectious disease risks. Research is needed to allow airport and aircraft operators to identify high-risk areas and activities and to develop more effective approaches to minimizing the spread of disease by air travel. The objectives of this research are to determine high-risk areas and activities conducive to human disease spread via droplet, airborne, and contact transmission modes (i.e., exposure opportunities) at airports and on aircraft; identify mitigation measures to address those risks; and provide guidance to help airports and aircraft operators use these measures to develop targeted strategies to respond to various types and levels of disease threats.

TI - Legal Aspects of Airport Programs. Topic 04-02. Legal Issues Related to Developing SMS and SMRD Documents Which May be Available to the Public
AB - Safety Management System (SMS) has been defined as a "systemic approach to managing safety, including the necessary organization structures, accountabilities, policies, and procedures" (International Civil Aviation Organization (ICAO), Safety Management Manual at 6.5.3 ICAO Doc. 9859-AN/474 (2d ed. 2009). SMS has four key elements: 1) Safety Policy which defines the methods and tools for achieving safety goals, including management accountability for such goals; 2) Safety Risk Management (SMR) which requires a proactive approach to identifying, categorizing both quantitatively and qualitatively risks, and establishing mitigation for identified risks; 3) Safety Assurance which includes a method for establishing processes to monitor an organization's performance in identifying risks and establishing preventive or corrective actions to maintain safety; and 4) Safety Promotion which involves the establishment of procedures and processes which change the safety culture and environment including the establishment of confidential reporting systems to encourage employee reporting and feedback as well as employee training. The central and distinguishing feature of SMS would require airports to adopt a proactive approach to safety assessment before there is an incident or accident. Under SMR, an airport would be required to document identified hazards, undertake risk analysis and assessment for such hazards and to develop mitigations. As a result of such SMR process, the airport would be required to identify both acceptable and unacceptable risk. The notice of proposed rule making (NPRM) indicates that an airport would take steps to reduce risks of hazards which presented as unacceptable. If a hazard is identified as low or has no associated risk, an airport may not have to proceed with mitigation. Under the NPRM, the airport would be required to retain documents for each SMR step (identification, assessment, proposed mitigation and acceptance of risk) for a period of time after undertaking risk analysis or implementing mitigation measures. The objective of the project was to produce a legal survey which could be used by attorneys advising airports in the implementation of SMS and the development of risk management systems under SMR. A survey should be conducted to reveal the following: (1) case law and statutes, which might impact such advice including cases in which airports and other transportation entities have been held liable for failing to adequately undertake risk analysis under a pre-SMS environment; (2) the types of strategies, which airports might use to manage legal risks associated with implementation of SMS, including examination of implementation strategies undertaken in other industries. For example, an Airport Cooperative Research Program (ACRP) indicates that other industries and aviation segments have utilized safety system principles including the petroleum, nuclear, railroad, marine and chemical industries, as well as other segments of the aviation industry (ACRP Report 1: Safety Management System for Airports: Volume1: Overview (2007); and (3) whether it would be worthwhile to implement certain regulatory changes to give the Federal Aviation Administration (FAA) and airports the authority to exempt from disclosure required SMS/SMR documentation and legislative changes to provide immunity to airports for compliance with FAA requirements. Also, the research should examine the extent to which discovery rules, and the rules of evidence, would permit discovery of the results of an SMS implementation plan and any studies that led to its adoption. Finally, the report should include recommendations identifying the elements that the proposer believes should and should not be included in an airport SMS and the proposed forms for such elements.

The project would research the legal issues associated with SMS and SMR compliance. Under SMS, airports may increase their liability risk by having identified risks as well as mitigations for such risks prior to the occurrence of accidents and incidents, an analysis which may, post-incident, be determined to be inadequate. Additionally, by creating an SMR database, airports will create records, which could be used to question airport safety practices leading to significant monetary damages or criminal proceedings in the event of an incident or accident implicating those practices. The objective of the project will be to produce a legal survey which could be used by attorneys advising airports in the implementation of SMS and the development of risk management systems under SMR.

TI - Guidance for Estimating Airport Construction Emissions
AB - As airports continue to expand and modify their infrastructure to meet the growing demand for air travel, they need to configure their growth within environmental constraints. Airport projects that rely on federal funding are required to have National Environmental Policy Act (NEPA)-supporting studies conducted to assess the environmental impacts of these projects. Many airport projects require construction to deal with additions or changes to runways, taxiways, aprons, terminal buildings, and parking facilities. Although emissions from construction equipment and associated activities are temporary in nature, they must be accounted for along with other applicable sources to meet regulatory requirements. While the understanding of emissions from various airport sources is improving, the methodology for calculating construction emissions remains highly variable. The Federal Aviation Administration's (FAA's) Emissions and Dispersion Modeling System (EDMS)/Aviation Environmental Design Tool (AEDT) currently does not explicitly account for construction emissions, and few resources offer guidance for estimating such emissions. As such, there is inconsistency in developing estimated emission levels based on what emission factors are used, how the equipment is characterized, and what activity data are used.

TI - Airport Costs and Production Technology: A Translog Cost Function Analysis with Implications for Economic Development Update
PY - 2011/07//Final Report
SP - 40p
AB - Based upon 50 large and medium hub airports over a 13 year period, this research estimates one and two output translog models of airport short run operating costs. Output is passengers transported on non-stop segments and pounds of cargo shipped. The number of runways is a quasi-fixed factor of production. Statistical tests reject the null hypothesis that airport production technology is homothetic and homogeneous, exhibits constant returns to scale, or reflects a Cobb-Douglas production technology. From the analysis, airports operate under increasing return s to runways utilization and increasing ray economies of scale for the two output model. Airport operating costs were 2% higher after the September 1, 2001 terrorist attacks. The input demand for general airport operations is price elastic and Morishima substitution elasticities indicate that Personnel, Repair-Maintenance-Contractual services, and General Airport Operations are substitutes in production. Based upon a one output passenger cost function model, an exploratory analysis identifies a relationship be tween the average cost of airport operations and indicators economic development. All else constant, a decrease in an airport’s real average operating costs is associated with increasing metropolitan employment , the number of establishments, and real gross metropolitan and state products.

TI - Aircraft Noise Characteristics and Metrics
PY - 2011/07//Dissertation
SP - 400p
AB - Day-Night Average A-weighted Sound Pressure Level (DNL) is used currently to define noise contours around airports and the 65 DNL contour is used as a criterion to determine qualification for noise insulation programs. There is concern that this metric with penalties for noise occurring at night does not adequately account for annoyance or broader noise impacts such as sleep disturbance. Much more sophisticated measures of perceived sound level (loudness) that adjust frequency weighting based on the characteristics of the sounds exist. Although loudness is considered to be the strongest noise attribute contributing to annoyance, there are other sound attributes, such as sharpness, tone, roughness and fluctuation strength that can also influence annoyance. In this research, several studies were conducted to examine the effects of noise characteristics on annoyance ratings of aircraft noise. A simulation program was developed to simulate aircraft noises so that individual characteristics could be varied while keeping others constant. Investigations on the influence of single characteristics such as spectral balance, roughness, fluctuation strength, and tone on annoyance ratings of aircraft noise have been conducted. Some evidence of an increase in annoyance with increases in roughness and tone was observed in these investigations. The influence of tone and roughness on annoyance ratings in the presence of loudness variations was also observed. Even when both loudness and tone varied, a strong sensitivity to tone persisted. Tone was the dominant sensation when both tone and roughness were varied and loudness was kept constant. The importance of tone and roughness increased when loudness did not vary very much. It was found that loudness, tone and roughness were, respectively, the first, second and third most influential characteristics. It was also seen that the use of loudness produces better predictions of average annoyance ratings. None of the metrics or models that are currently used for environmental noise annoyance incorporate measures of loudness, tone, and roughness together. In this research, a model based on the Psychoacoustic Annoyance developed by Zwicker, Fastl and others that combines the effects of loudness, tone and roughness to predict annoyance due to aircraft noise was developed. The developed model was found to be a better predictor of aircraft noise annoyance than any other metric or models that are currently used to evaluate aircraft noise.

SP - 77p
AB - This report documents work done to enhance terminal area aircraft performance modeling in the Federal Aviation Administration’s Aviation Environmental Design Tool (AEDT). A commercially available aircraft performance software tool was used to develop data in a form usable by the AEDT. These data were compared to actual aircraft performance data measured by flight data recorder systems. The terminal area fuel consumption data were shown to average about 2% different from the measured fuel consumption for departures and about 5% different for arrivals.

TI - Airport Sustainability Practices: Tools for Evaluating, Measuring, and Implementing
AB - Airport sustainability encompasses a wide variety of practices that ensure protection of the environment, including conservation of natural resources; social progress that recognizes the needs of all stakeholders; and maintenance of high and stable levels of economic growth and employment. Many airports have begun to incorporate sustainability practices into their planning, construction, and daily operations because of their tangible benefits to them and their community or to respond to regulation and policy. Many airports, however, have also found barriers to implementing sustainability practices, including limited resources, lack of sustainability evaluation tools, staffing challenges, and lack of understanding and/or awareness. While there have been many efforts to define sustainability and to identify airport sustainability practices, there is no broad, industry-adopted approach to evaluate and select best practices, nor is there a rating system to gauge airport sustainability performance. Research is needed to develop a tool to help airports evaluate and select sustainability best practices, develop a rating system to gauge airport sustainability performance, and to assess the viability of industry-wide adoption of a rating system and voluntary certification program. The objectives of this research are to (a) develop a decision tool for airports to identify, evaluate, prioritize, and select sustainability practices; (b) develop a prototype sustainability rating system to help airports and their stakeholders gauge sustainability performance; and (c) evaluate the viability of implementing the rating system and an associated voluntary airport sustainability certification program.

TI - Integrated Noise Model Accuracy for General Aviation Aircraft
AB - Although the Federal Aviation Administration (FAA) has developed and continuously improved its Integrated Noise Model (INM) since the 1970s, the focus of these improvements has been on the sound level database for large commercial jets. Information from some general aviation (GA) airports suggests INM has over predicted GA noise impacts resulting in an inaccurate representation of noise contours. These disparities can lead to noise contours that do not reflect actual sound levels, which, in turn, may compromise compatible land use planning and result in unnecessary funding of noise mitigation. Research is needed to determine the accuracy of INM in predicting GA noise impacts, identify causes for these disparities, and identify potential solutions to improve the model and its use. The objectives of this research are to: (1) assess the predictive accuracy of the INM for GA aircraft, (2) identify causes for deviations between actual and predicted values, (3) identify potential solutions to improve the model's accuracy, and (4) describe the steps needed for their implementation.

TI - The Impact of Regulatory Compliance Costs on Small Airports
AB - Over time, federal, state, and local governments have gradually increased the regulatory requirements on U.S. airports. The costs associated with incorporating ongoing regulations in a wide array of subject areas have steadily added to airport operating costs. There is a growing concern for small and nonhub airports that have limited staff and financial resources with which to fulfill their regulatory responsibilities. For many small airports, lower passenger enplanements limit their ability to raise revenue or cut costs significantly to make up for the financial requirements of increased regulation. With budgets already stretched by operating costs and capital expenditures, many small airports are struggling to absorb compliance costs associated with the cumulative regulatory requirements. While government agencies provide some funding for new regulatory initiatives, costs attributed to ongoing compliance remain unfunded. The objective of this research is to identify and quantify (cost) the cumulative effects of regulatory compliance requirements at small and nonhub airports. The research analyzed each requirement from initial implementation through ongoing maintenance, and estimated its associated costs. Each requirement was matched up to the funding sources (if any) associated with that particular regulatory requirement. The report provides airport operators and others with an understanding of the cumulative effects of regulatory compliance requirements.

TI - Understanding the Relationship between Aviation Economics and the Broader Economy
AB - Project 31 analyzed the effects of a potential introduction of a cap-and-trade policy in the aviation industry. Analyses were conducted through the joint application of the Aviation Environmental Portfolio Management Tool, in particular the APMT Economics module, and a global model of economic growth and greenhouse gas emissions, the Massachusetts Institute of Technology (MIT) Emissions Prediction and Policy Analysis (EPPA) model. Where the EPPA model's outputs provide information on the world economy, changes of greenhouse gas emissions and the expected cost of carbon, APMT Economics focused on the airline industry, and provided outputs such as operating costs of airlines, demand, or airline fleets. While the project focused initially on the implications of a cap-and-trade policy, the tools enabled the study of a variety of other mitigation options -- for example, the extent to which mandates for renewable fuels in one sector can influence price and availability in other sectors, or the relative economic efficiency of sector-based regulations and standards versus broader economy-wide measures.

TI - Improving Terminal Design to Increase Revenue Generation Related to Customer Satisfaction
AB - Traditional terminal planning and design approaches typically focus on passenger and baggage processing and functional requirements. While the movement of passengers and bags between the curb and the aircraft is the basic functional role of a terminal, the atmosphere created by the mix of services and facilities in a terminal can greatly impact the economics of the airport and passenger satisfaction. A more satisfied passenger experience can lead to increased revenue generation through additional concession sales. As a result, overall passenger activity may increase as travelers select a particular airport in part due to the terminal layout and amenities offered. Further dwell time can vary due to irregular operations and other conditions that often result in passengers remaining in their terminals for extended periods of time. In addition to the challenges of day-to-day operations, airports also face a highly dynamic and volatile operating environment with frequent changes in security and technology. The objective of this research is to produce a handbook of global best practices for airport management and industry professionals to foster innovative airport planning and terminal design in promoting profitable revenue generation and customer satisfaction at a variety of airport sizes and types. The handbook should include consideration of how to facilitate innovation in improving the customer experience through the use of technology and other resources.

TI - Assessing Opportunities for Alternative Fuel Distribution Programs
AB - Increasingly, airports and their tenants are examining the potential to introduce alternative fuels, including alternative jet fuel, at their facilities. Airports, however, may lack the information and analytical tools to evaluate the business case for implementing alternative fuels distribution programs. Many projects are under consideration around the country for production of alternative jet fuels. For example, there is an ongoing effort to bring alternative jet fuel production and distribution to the northwest region. The production of alternative jet fuel results in a variety of co-products such as renewable diesel, which raises an additional desire to find markets for these co-products of alternative jet fuel production. Given the concentrated demand for fuel product at or near airports, airports may have the potential to become distribution centers for the co-products of alternative jet fuel production as well as other alternative fuels. Optimizing the potential for alternative fuel use from a broad business view can offer airports a new sustainable business and environmental opportunity, can promote aviation growth, and can create jobs at airports and in the region. The objective of this research is to develop a guidebook for airports to introduce and market alternative fuels to their airport community that includes tenants and consumers off airport. This guidebook will include a description of the steps necessary to evaluate opportunities and constraints for program delivery and will include a toolkit that enables airport decision makers to evaluate all of the elements necessary to implement an alternative fuels marketing and distribution program.

TI - Guidance for Treatment of Deicing-Impacted Airport Stormwater
AB - Airports across the United States face increasing regulatory and technical challenges for addressing runoff containing glycol-based aircraft deicing and anti-icing fluids (ADFs) associated with deicing operations. The handling and discharging of this runoff, which represents millions of gallons of stormwater and wastewater, present unique challenges for airports as requirements vary from state to state. Although the Effluent Limitation Guideline (ELG) being developed by the Environmental Protection Agency (EPA) will likely standardize effluent limits and/or collection efficiency requirements, it will not provide airports with the information needed to evaluate treatment options or help them achieve the new effluent limitations with which they must comply. Several airports have applied biological treatment as a method of treating deicing stormwater runoff; however, the effects of cold water temperatures on system performance have not been sufficiently researched or documented. In addition, the potential effect of stormwater that contains a mixture of aircraft and pavement deicers on treatment efficiency has not been investigated. Research is needed to evaluate both onsite and offsite treatment and pretreatment solutions for deicing runoff generated at airports. The objectives of this research are to (1) identify available and emerging onsite and offsite technologies for treating stormwater impacted by airport deicing activities, (2) evaluate the performance of available technologies as implemented at airports, and (3) provide guidance to help airports select technologies for treating deicing-impacted stormwater.

TI - Quantifying Aircraft Lead Emissions at Airports
AB - The current National Ambient Air Quality Standard (NAAQS) for lead is significantly more stringent than the previous standard. Current regulations are believed to affect five airports, which have numerous operations from piston engine aircraft that use leaded aviation gas (avgas). On December 23, 2009, the U.S. Environmental Protection Agency (EPA) proposed to revise the ambient monitoring requirements for measuring airborne lead. The proposed regulation changes the lead monitoring threshold and may affect up to 73 airports. This revised threshold will be the basis for State Air Quality agencies requiring source-oriented monitors be installed near any applicable source, and it may require airports to be treated as any other source of lead when determining whether source-oriented lead monitoring is needed. The inputs used to determine applicability were based on a number of assumptions and can be improved by obtaining airport-specific information. The EPA has limited quantitative data to evaluate on-airport or off-airport ambient lead concentrations associated with airports. If this proposed regulation is enacted, airports would need to document applicability or work with state agencies to monitor ambient lead concentration of the surrounding air. Airport owners and operators may face future regulatory and resource impacts to quantify or mitigate emissions. As such, research is needed to assist airports in quantifying lead emissions from leaded avgas that accounts for applicable variables. The objective of this research is to develop an inventory methodology to help airports quantify aircraft lead emissions at airports.

AB - U.S. Space-Based Positioning, Navigation, and Timing Policy states that a “fundamental goal of this policy is to ensure that the United States maintains space-based positioning, navigation, and timing services, augmentation, back-up, and service denial capabilities that: (1) provide uninterrupted availability of positioning, navigation, and timing services; (2) meet growing national, homeland, economic security, and civil requirements, and scientific and commercial demands; (3) remain the pre-eminent military space-based positioning, navigation, and timing services; (4) continue to provide civil services that exceed or are competitive with foreign civil space-based positioning, navigation, and timing services.” Global Positioning System (GPS) modernization includes new signals and capabilities required to be compatible with the use of existing GPS receivers designed in compliance with specifications and standards in existence at the time of the receiver design. Compatibility with federal augmentation system (Wide Area Augmentation System [WAAS], Local Area Augmentation System [LAAS], Nationwide Differential GPS [NDGPS], and Maritime DGPS [MDGPS]) receivers in accordance with the specifications of these systems is also required. Further, in 2004, the U.S. signed an agreement with the European Union establishing cooperation between GPS and the European Galileo system. The Agreement specifically states “The Parties shall work together to promote adequate frequency allocations for satellite-based navigation and timing signals, to ensure radio frequency compatibility in spectrum use between each other’s signals, to make all practicable efforts to protect each other’s signals from interference by the radio frequency emissions of other systems, and to promote harmonized use of spectrum on a global basis, notably at the ITU.” In 2007, the U.S. Federal Aviation Administration (FAA) submitted a letter to the International Civil Aviation Organization (ICAO), in lieu of an agreement, which “reaffirms the United States Government’s commitment to provide the GPS Standard Positioning Service (SPS) for aviation throughout the world. Further, the United States commits to provide the Wide-Area Augmentation System (WAAS) service within its prescribed service volume.” The letter goes on to state that “The U.S. Government plans to take all necessary measures for the foreseeable future to maintain the integrity, reliability and availability of the GPS SPS and WAAS service and expects to provide at least six years’ notice prior to any termination of such operations or elimination of such services.” On 9 Feb 2011, the Executive Steering Group (ESG), via the National Coordination Office (NCO) of the National Executive Committee (EXCOM) for Space-Based Positioning, Navigation, and Timing (PNT), directed the National Space-Based PNT Systems Engineering Forum (NPEF) to conduct an assessment of the effects of LightSquared’s planned deployment of terrestrial broadband systems to GPS receivers and GPS-dependent systems and networks.

PY - 2011/06//PARTNER Project 33 Final Report
SP - 25p
AB - Airports around the nation are considering expansion plans in order to meet increasing demand for aviation transport. There are increasing concerns, as well, about how and to what extent air pollutant emissions from airports contribute to local and regional air quality degradation and hence to negative impacts on human health and welfare. However, it is difficult to quantify the amount, transport, and secondary conversion processes of aircraft emissions, which usually comprise the bulk of airport-attributable emissions. This is due to four reasons: 1. Difficulty of determining the actual amounts of emissions from aircraft and characterizing the chemical speciation. 2. Difficulty of determining, at the particle level, the secondary chemical transformations that occur. 3. Difficulty in detection of the species and identification of the aircraft contribution in a region where air quality degradation is a consequence of emissions from multiple sources, both natural and anthropogenic. For the project described in this report, the technique of stable isotopic measurements was utilized in an attempt to develop and assess the impact of aircraft emissions in a region. The theme was, “Are the aircraft emissions recognizable at the isotopic level in a region and are they separable from other sulfates?” To explore this theme, the project team performed three measurement campaigns at Los Angeles International Airport (LAX) to sample aerosol sulfate and characterize the isotopic composition of oxygen atoms in the sulfate particles. It was hoped that aerosol sulfate from jet engines would be shown to have a distinct isotopic character in comparison to sulfate from other sources such as diesel engines, aiding attribution of degraded air quality to jet aircraft sources. The premise that the oxygen isotopic composition of aerosol sulfate could be used to define jet contributions to a region was ultimately not conclusively supported by the study presented in this report. It appears that at low humidity an isotopic anomaly is preferentially created, as observed in the first Aviation Alternative Fuels Experiment (AAFEX), thus identifying a jet aircraft engine. At the humidity of LAX however, the presence of excess water on the aerosol surfaces dilutes the anomaly. Hence, for assessment of the potential of the technique to be broadly applied, it is likely that only low-humidity areas would be capable of providing the signature, based upon the experiments conducted to-date. Furthermore, unexpectedly low sulfate concentrations were observed in the study, suggesting that jet engine exhaust SO2 oxidation occurs further away from LAX and optimal sampling sites in future studies would need to be done at further distances. However, it is unlikely that increased distance between the source sulfur and the sampling monitors at LAX will show much isotopic anomaly in high humidity conditions (60+ %). Conceptually, the potential remains for isotopic analysis to quantitatively address the contributions from aircraft jet engines to degraded air quality near airports. If future research is performed on this technique, an airport in a dry environment must be selected as an initial candidate so that the methods initially explored in this report can be retried. Monitors may need to be located further away from the airport environment so that engine SO2 has more opportunity to become sulfate.

TI - Fatigue Risk Management in Aviation Maintenance: Current Best Practices and Potential Future Countermeasures
PY - 2011/06//Final Report
SP - 42p
AB - The unregulated hours and frequent night work characteristic of maintenance can produce significant levels of employee fatigue, with a resultant risk of maintenance error. Fatigue Risk Management Systems (FRMS) are widely used to manage fatigue among flight crew and drivers of commercial vehicles, but comprehensive approaches to fatigue risk management are still uncommon within maintenance organizations. In the wider transport industry, the objective of most FRMS has been to reduce fatigue to an acceptable level. Two additional objectives can be identified for FRMS in the maintenance environment: reducing or capturing fatigue-related errors, and minimizing the harm caused by fatigue-related errors. A range of countermeasures can help to achieve these three objectives in aviation maintenance. Some of these countermeasures are currently being applied within the industry, while others may become feasible in the future. The data available on best practices for fatigue risk management in aviation maintenance are continually evolving. This should be considered an interim report.

TI - Evaluation of Continuous Descent Approach in Normal Air Traffic Conditions
PY - 2011/05/31/Final Report
SP - 24p
AB - This project investigates the impact of Continuous Descent Approach (CDA) about the inbound traffic in the terminal airspace. The impact includes fuel consumption and total flight time savings. This project differs from other CDA projects in that it evaluates the CDA under normal air traffic conditions where congested traffic is taken into account. Flying a CDA trajectory increases the risk of potential collision as the pilot may have less control on the aircraft under near idel thrust settings. Evaluation of fuel consumption and flight time only makes sense when the inbound traffic employing CDA is conflict-free. Safety can be guaranteed by employing conflict detection resolutions (CDR). Although tactic manuevers, such as heading change, horizontal speed change, and vertical speed change, are able to solve the most immediate collision, they potentially interrupt the near idel thrust settings. Consequently, the CDA trajectory is aborted. In this project, a strategic solution is developed which sequences the arriving aircraft under minimum separation constraints as well as miles-in-trail constraints. In addition to inter-aircraft separation, this project also takes into account the mutual interference between streams flowing into airports of a metroplex. The fuel consumption and delay for deconfliction are counted when the fuel and flight time savings are evaluated. The proposed CDR is applied to the major airports and metroplex airports in the United States. Fuel statistic and flight time are obtained from the Future ATM Concept Evaluation Tool (FACET). By comparing the conflict-free CDA to the conflict-free Step-down approach, the benefits of CDA as well as the associated trade-off are quantified.

TI - Microprocessor Evaluations for Safety-Critical, Real-Time Applications: Authority for Expenditure No. 43 Phase 5 Report
PY - 2011/05//Final Report
SP - 58p
AB - This report documents the results of Phase 5 of the Aerospace Vehicle Systems Institute Authority for Expenditure (AFE) 43 Microprocessor Evaluations Project that provides research information intended to help aerospace system developers, integrators, and regulatory agency personnel in the selection and evaluation of commercial off-the-shelf microprocessors for use in aircraft systems. This report describes the cooperative research accomplished by contributing members of the aerospace industry and the Federal Aviation Administration (FAA). The project objectives included (1) identifying common risks of using a system-on-a-chip (SoC) and mitigation techniques to provide evidence that they satisfy regulatory requirements and (2) evaluating existing regulatory policy and guidelines against the emerging characteristics of complex, nondeterministic microprocessors and SoCs to support the certification of aircraft and qualification of systems using these devices. Complex aircraft system development requires more robust consideration of system failure and anomaly detection, correction, and recovery. The safety net approach identified in this report provides a means to address the lack of design assurance for highly integrated, complex, nondeterministic airborne electronic hardware within aircraft systems. Airworthiness assurance of these SoCs by safety net techniques may help to contain the labor burden and costs of compliance to FAA regulations while maintaining safety requirements as SoCs continue to become more complex and more widely used in aircraft systems. The safety net approach is consistent with, and does not replace, current FAA policy and guidelines.

TI - Improvements in Aircraft Fire Safety Derived from FAA Research Over the Last Decade
PY - 2011/05
SP - 36p
AB - This technical note is an overview of Federal Aviation Administration (FAA) fire safety research over the past 10 or more years, with a focus on in-flight fire safety. The technical note emphasizes research accomplishments that have been, or are being, implemented into commercial aviation, as well as other important fire safety research. The research was driven by fatal accidents and safety concerns associated with new technology, such as: (1) hidden fire protection research led to the development of an improved fire test method for thermal acoustic insulation, which became a new FAA requirement, and the issuance of airworthiness directives to remove certain flammable insulation; (2) practical and cost-effective fuel tank inerting system was developed, enabling FAA to issue a regulation requiring flammability reduction in heated center wing fuel tanks. Related studies addressed the limiting oxygen concentration required to prevent a fuel tank explosion and fuel tank flammability; (3) a new test method was developed and mandated by the FAA that measures the burnthrough resistance of thermal acoustic insulation during a postcrash fuel fire; (4) hazardous materials research led to the adoption of new regulations and advisory material to provide safeguards for the shipment of oxygen generators/cylinders, lithium batteries, and aerosol cans; (5) research findings on structural composites were employed during the certification of the Boeing 787 to provide safety against a hidden in-flight fire, postcrash fire fuselage burnthrough resistance, and fuel tank flammability; (6) minimum performance standards were developed for halon replacement agents in lavatories, hand-held extinguishers, engines and cargo compartments, and the effectiveness and safety of replacement agents was evaluated; and (7) long-range fire safety research identified promising new ultra-fire-resistant polymers and improved the science for experimental and theoretical evaluation of material fire performance. In summary, FAA fire safety research over the past decade (2000-2010) developed technology that resulted in the adoption/issuance of five final regulations, two Airworthiness Directives, two Advisory Circulars, and two Safety Alerts for Operators, which are expected to significantly improve aircraft fire safety. In addition, this research also supported the certification of the all-composite fuselage, new Boeing 787 to ensure a high level of fire safety and the replacement of halon extinguishing agents and made important gains in characterizing and predicting the burning behavior of polymers and in developing ultra-fire-resistant interior materials.

AB - The Traffic Alert and Collision Avoidance System (TCAS) provides a pilot the range and bearing of nearby aircraft. TCAS obtains the bearing information by using an angle-of-arrival antenna. In the development of TCAS at Lincoln Laboratory, the first airborne tests were conducted using an Adcock antenna, which is a small square array of four monopole elements. This report describes an alternative antennas for TCAS, using three elements in the shape of a triangle. It is shown that the triangle antenna is less sensitive to receiver noise, and that improvement factor is about 10 dB.

TI - Ionizing Radiation in Earth’s Atmosphere and in Space Near Earth
PY - 2011/05//Final Report
SP - 32p
AB - The Civil Aerospace Medical Institute of the FAA is charged with identifying health hazards in air travel and in commercial human space travel. This report addresses one of these hazards – ionizing radiation. Ionizing radiation is a subatomic particle of matter or packet of energy (photon) with sufficient energy to eject an orbital electron from an atom. Charged subatomic particles from exploding stars (supernovae) are a constant source of ionizing radiation in the atmosphere and in space. In space another constant source of ionizing radiation is the solar wind from the Sun. The solar wind consists mostly of electrons and protons with energies between 10 and 100 keV. The Sun undergoes an approximately 11-year cycle of rise and decline in activity and during its active phase there is an increased emission of the solar wind and occasional eruptions of high-energy particles (coronal mass ejections). Other sources of ionizing radiation during air travel include radioactive cargo, radioactive substances released into the atmosphere as a result of a nuclear reactor accident or terrorist activity, lightning, and terrestrial gamma-ray flashes. A health effect following exposure to ionizing radiation for which the severity is radiation dose related is called a deterministic effect (non-stochastic effect, tissue reaction). Deterministic effects may occur soon after radiation exposure. For example, nausea and vomiting might be experienced by a space traveler a few hours after receiving a large dose of ionizing radiation while outside a space vehicle during a coronal mass ejection. If the probability (risk) of a health effect after exposure to ionizing radiation is dose related, it is called a stochastic effect. Such effects seldom occur until years after the radiation exposure. Examples of stochastic effects are cancer and genetic disorders. If one or both parents are irradiated prior to conceiving a child, there is a risk of genetic disorders in the child and in its progeny. The report can be used as a source book for instruction on ionizing radiation exposure of air and space travelers.

TI - The Impact of Climate Policy on U.S. Aviation
PY - 2011/05
SP - 19p
AB - The authors evaluate the impact of an economy-wide cap-and-trade policy on U.S. aviation taking the American Clean Energy and Security Act of 2009 (H.R.2454) as a representative example. They use an economy-wide model to estimate the impact of H.R. 2454 on fuel prices and economic activity, and a partial equilibrium model of the aviation industry to estimate changes in aviation carbon dioxide (CO2) emissions and operations. Between 2012 and 2050, with reference demand growth benchmarked to International Civil Aviation Organization/Group on International Aviation Climate Change (ICAO/GIACC) (2009) forecasts, the authors find that aviation emissions increase by 130%. In their climate policy scenarios, emissions increase by between 97% and 122%. A key finding is that, under the core set of assumptions in this analysis, H.R. 2454 reduces average fleet efficiency, as increased air fares reduce demand and slow the introduction of new aircraft. Assumptions relating to the sensitivity of aviation demand to price changes, and the degree to which higher fuel prices stimulate advances in the fuel efficiency of new aircraft play an important role in this result.

TI - Development, Validation, and Deployment of an Occupational Test of Color Vision for
Air Traffic Control Specialists
PY - 2011/05
SP - 36p
AB - Air Traffic Control Specialists (ATCSs) are responsible for the safe, efficient, and orderly flow of traffic in the U.S. National Airspace System. Color has become an integral element of the air traffic control environment. It is used to communicate information to ATCSs about various modes of air traffic functions including conflict alerts, aircraft control status, and weather. The Federal Air Surgeon (AAM-1) and Human Factors Research, Engineering, and Development office (AJP-61) tasked the Civil Aerospace Medical Institute (CAMI) to develop, validate, and implement an occupational test for ATCS job candidates who fail clinical instruments during the pre-employment medical examination. The Aerospace Human Factors Research Division (AAM-500) of CAMI developed the Air Traffic Color Vision Test (ATCOV) to determine whether individuals with color vision disorders (CVDs) have adequate color vision to perform critical color-related tasks involved in air traffic control. The research team conducted two studies to validate ATCOV testing. The results of Study One provided evidence of the reliability of the subtests, established performance norms for subjects with normal color vision (NCV) on each subtest, determined cut scores to apply in occupational testing, and examined the impact of testing upon a sample of CVD subjects. The results of Study Two provided evidence of the reliability of second operational ATCOV subtests, established performance norms for NCV subjects on each subtest, determined cut scores to be applied in occupational testing, and examined the impact of testing upon a sample of CVD subjects. Color vision ability sufficient to perform duties safely remains critical to provision of air traffic services in the National Airspace System. ATCOV complies with Uniform Guidelines reporting requirements for both content and construct-oriented validity. Evidence of content validity for ATCS duties is provided through direct sampling of form and content of critical display data. Evidence of construct validity is provided by correlation with Colour Assessment and Diagnosis Test and Cone Contrast Test threshold scores, which precisely measure color vision ability. This resulted in a job sample test closely tied to critical tasks communicated using color on air traffic displays. ATCOV makes use of display formats and color chromaticities deployed for critical information on critical displays as defined by published analyses of ATCS tasks. Its items are isomorphic with datablocks and weather depictions deployed on ARTS, STARS, and DSR displays in terminal and en route facilities. Future challenges will surround the stability of color use on new systems and displays.

TI - Legal Aspects of Airport Programs. Topic 04-07. Procurement of Airport Development and Planning Contracts
AB - The objective of this research is to produce an easy-to-use compendium of procurement requirements applicable to airport contracting. The compendium should address contracts receiving financial support through Airport Improvement Program (AIP) as well as the America Relief and Recovery Act (ARRA) and state procurement requirements that would apply whether or not federal funds are involved. The report should also discuss procurement requirements when a state is acting as a "pass-through" for federal funds, i.e. when an airport is a sub-grantee of a state agency receiving a federal grant. The report should address the relationship (or hierarchy) of federal, state, and local procurement requirements in the case of federally funded contracts and the relationship (or hierarchy) between state and local procurement requirements for contracts without federal funds. The resulting research report should include summaries of federal and state requirements (for each state), statutory or regulatory citations, and web links to the cited statutes or regulations. Leading cases (judicial and administrative decisions)--to the extent available--interpreting the provisions should also be included. The research report should also distinguish between procurement for construction contracts, equipment purchases and professional services. Discussion of local procurement requirements would be limited to the issue of the relationship between such requirements and state and local requirements. Issues to be examined include: (1) What is the applicability of 49 CFR § 18.36 and of statutory procurement requirements in the AIP statute to airport contracts? (2) What is the relationship between federal requirements for AIP-funded contracts and state or local procurement requirements? Which requirement will govern in the case of a conflict? Is the result any different if the airport is not receiving the funds directly from the federal government but is a sub-grantee of a state agency that received the funds? (3) What kind of state or local provisions have been determined to be in conflict with federal requirements? What kind of requirements have been found to be consistent with federal requirements? For AIP-funded contracts, what are the requirements of 49 CFR § 18.36 with respect to the following: (a) Solicitation procedures; (b) Selection of awardee for the contract; (c) Protest procedures; and (d) Substantive provisions required in solicitations, e.g., bonding requirements, minimum wage rate requirement, contractor residency, or disadvantaged business participation goals. (5) What are the exceptions to the general requirement of competition in section 18.36 and what are the circumstances in which they have been found to apply? In what circumstances has an airport operator been unsuccessful in seeking an exception? (6) For contracts funded under AIP or ARRA, what are the statutory requirements with respect to the following: (a) Solicitation procedures; (b) Selection of awardee for the contract; (c) Protest procedures; (d) Substantive provisions required in solicitations, e.g., bonding requirements, minimum wage rate requirement, contractor residency, or disadvantaged business participation goals. (6) What are the requirements in the various state laws applicable to airports with respect to the following: (a) Solicitation procedures; (b) Selection of awardee for the contract; (c) Protest procedures; and (d) Substantive provisions required in solicitations, e.g., bonding requirements, minimum wage rate requirement or disadvantaged business participation goals. (7) What are the consequences or remedies for failure to comply with applicable requirements under: (a) 49 CFR §18.36; (b) The AIP and ARRA statutory provisions; and (c) The various state procurement laws and regulations (8) What are the exceptions to the general requirements of competitive solicitation under: (a) 49 CFR §18.36; (b) The AIP and ARRA statutory provisions; and (c) The various state procurement laws and regulations (9) What are the tests and interpretations applicable to the relevant provisions of 49 CFR §18.36, the AIP statute, ARRA and the various state Buy America Requirements? (10) Are there any other federal, state, or local Buy America requirements may be applicable to Federal Aviation Administration (FAA)-financed airport projects?

The compendium should address contracts receiving financial support through Airport Improvement Program (AIP) as well as the America Relief and Recovery Act (ARRA) and state procurement requirements that would apply whether or not federal funds are involved. The report should also discuss procurement requirements when a state is acting as a "pass-through" for federal funds, i.e. when an airport is a sub-grantee of a state agency receiving a federal grant. The report should address the relationship (or hierarchy) of federal, state, and local procurement requirements in the case of federally funded contracts and the relationship (or hierarchy) between state and local procurement requirements for contracts without federal funds. The resulting research report should include summaries of federal and state requirements (for each state), statutory or regulatory citations, and web links to the cited statutes or regulations. Leading cases (judicial and administrative decisions)--to the extent available--interpreting the provisions should also be included. The research report should also distinguish between procurement for construction contracts, equipment purchases and professional services. Discussion of local procurement requirements would be limited to the issue of the relationship between such requirements and state and local requirements.

TI - System Level Implications of Changes in Future Aircraft Mission Specifications
AB - Future reductions of fuel burn and green house gas emissions from commercial aviation will be, in large part, achieved through the development and use of more fuel- and environmentally-efficient aircraft. Achieving significant efficiency improvements at the aircraft level may require opening up the design space so as to consider changes in aircraft design mission specifications/capabilities such as lower cruise speed, different payload-range characteristics, and longer wing span. However, there are potentially serious and unforeseen system-wide implications (economics, viability, delays, manufacturability, etc.) that could result from these changes and that have not yet been quantified properly. The main objective of this project is to understand and quantify these implications so that informed decisions can be made.

AB - This project will develop (i) a weather prediction model extending from Earth's surface to the edge of space and (ii) a micrometeoroid detection and risk assessment system that, together, predict the environmental conditions needed for safe orbital, entry, descent and landing operations. The project will develop a whole atmosphere model (WAM) that includes assimilation of real-time data throughout the atmosphere (0-600 km), and that will seamlessly provide neutral and ionosphere densities and wind forecasts throughout the orbital (200-400 km), entry (~80-200 km), and descent and landing (0-80 km) operational regimes. The project will provide the first characterization of meteoroid parameters, including density, in order to provide satellite risk assessment.

TI - Laser Illumination of Flight Crew Personnel by Month, Day of Week, and Time of Day for a 5-Year Study Period: 2004-2008
PY - 2011/04
SP - 14p
AB - INTRODUCTION: Illumination of civilian and military aircraft by laser beams in the National Airspace System (NAS) has concerned the aviation community for nearly two decades. The principal concern is the affect laser exposure may have on flight crew personnel during landing and departure maneuvers when operational requirements are critical. This study examines the frequency of aviation-related laser event reports by month, day of the week, and time of day. METHODS: Reports of aircraft illuminated by high-intensity light sources have been consolidated from multiple information sources into a database maintained by the Civil Aerospace Medical Institute’s Vision Research Team. Laser illumination event data involving civilian aircraft in the United States for a 5-year period (January 1, 2004 to December 31, 2008) were examined for this study. RESULTS: There were a total of 2,492 laser events in the U.S. during the study period. In 1,676 (67.3%) of these, the cockpit environment was illuminated by a laser light. August through December were the most active months with 51% of all reports, while May through July were the least active with only 19% of all reported incidents. Sunday was the most likely day of the week for an aircraft to be illuminated by a laser (15.4%), with a relatively high number of aircraft illuminations occurring on Friday and Saturday. Weekdays exhibited the fewest laser illumination events. Time of day was provided in 2,429 (97.5%) aircraft laser illumination reports. Approximately 69.8% (1,696) of the aircraft illuminations occurred between 7 p.m. (1900 hours) and 11 p.m. (2300 hours) during the study period. CONCLUSIONS: Laser illumination events are most likely to occur from late summer to early winter months and on weekends between 7:00 p.m. and 11:00 p.m. Both weather conditions and daylight savings time may play important roles in determining an opportune time frame for laser activity in a particular locale. Knowledge of these findings may assist the aviation community and law enforcement officials in allocating their limited resources to increase the likelihood of apprehending those responsible for these criminal acts.

TI - Testing Web-Based Preflight Weather Self-Briefing for General Aviation Pilots
PY - 2011/04
SP - 26p
AB - The Internet affords an increasingly capable, economical, and popular vehicle for preflight weather self-briefing. This research constitutes the first known experimental investigation of how modern Web-based weather products are actually being used by general aviation (GA) pilots. A data-gathering emulation of the National Weather Service Web site http://aviationweather.gov was written for use on a personal computer. Eighteen Web pages were created to display weather information, each page emulating a similar category of product shown by aviationweather.gov. This formed the primary weather briefing site for two similar, challenging weather scenarios subsequently flown by 50 GA pilots in simulated cross-country VFR flight. Two dependent variables were measured—page views (which pages each pilot viewed) and pageview duration (how long each page was viewed). Total briefing time was then calculated for each pilot by summing pageview durations. A groupwise “dwell” index was also derived for each Web page by multiplying the group’s page views times its median pageview durations. A number of specific findings emerged from the data analysis. First, given a specific flight mission, the author found that, as a group, GA pilots appeared significantly consistent over time in the kinds of information they sought out. However, the amount of time they spent examining that information seemed to vary over time, even given similar flight situations. Second, pilots seem to have favorite information sources (e.g., graphical prog charts, TAFs, NEXRAD, and satellite cloud images). We could expect those favorites to shift slightly, depending on the flight mission. Third, Web page design is potentially important. For example, pages not accessible from the top-level menu may be ignored or overlooked. These findings are important to weather information providers because the ability to display certain types of information—and certain ways of displaying it—are sure to give the knowledgeable provider an advantage over competitors. The key is to have highly informative pages that still remain easy to understand.

TI - Establishing the Reliability and Validity of the Perceptions of Flight Operations Quality Assurance (PFOQA) Questionnaire
PY - 2011/04
SP - 26p
AB - Though the majority of Part 121 flights are operated by airlines that have FAA-approved Flight Operations Quality Assurance (FOQA) programs, only 17% of the smaller carriers have them. A recent report cited pilots’ concerns about data misuse as one of the primary factors preventing participation in voluntary safety programs (GAO, 2010). Thus, increased participation in FOQA may depend on gaining insight into pilots’ perceptions and developing strategies to mitigate their concerns. The present study is an evaluation of the reliability and validity of the Perceptions of Flight Operations Quality Assurance (PFOQA) questionnaire scales. The PFOQA scales were based on the assumption that negative and positive perceptions of FOQA programs represent two distinct dimensions consisting of expectations about positive safety enhancements and concerns about data misuse. Though the Positive Perceptions Scale ( =.86) and the Negative Perceptions Scale ( =.88) both demonstrated good internal consistency reliability, the results of Principal Components Analysis and Content Analysis suggest that the PFOQA items may not represent a sufficient sample of pilots’ expectations and concerns in order to draw valid inferences about their perceptions of existing FOQA programs. Rather, the PFOQA questionnaire seems best suited for assessing pilots’ attitudes prior to FOQA implementation. Providing feedback on questionnaire results and communicating how the airline plans to address pilots’ concerns can set the stage for a positive program introduction. Certainly, the potential safety benefits of FOQA programs justify efforts to understand and mitigate negative perceptions that might prevent their adoption.

TI - FAA Must Improve its Controller Training Metrics to Help Identify Program Needs
PY - 2011/03/30
SP - 12p
AB - The Federal Aviation Administration (FAA) plans to hire and train nearly 11,000 new air traffic controllers through fiscal year (FY) 2019 to replace the large numbers of those now retiring. As FAA begins training this influx of new hires, it must have accurate metrics on their training progress to ensure that key air traffic control facilities have enough controllers for safe and efficient operations. In 2009, at the request of Representative Jerry F. Costello, then Chairman of the House Subcommittee on Aviation, the U.S. Department of Transportation Office of Inspector General (OIG) reviewed training failures among newly hired air traffic controllers. During that review, OIG found that FAA’s reported training failure rate was not accurate and that FAA’s primary source of training failure data, the National Training Database (NTD), contained outdated and inaccurate data. Both are critical metrics for managing this important program. This review follows up on OIG's 2009 audit. The audit objectives were to (1) evaluate FAA’s actions to improve its system for tracking the training progress of newly hired controllers and (2) review FAA’s metrics for measuring and reporting the effectiveness of its controller training program. Briefly, FAA has improved its tracking process for new controller training over the last year. The Agency has taken a number of corrective actions to address the problems OIG identified in 2009 that contributed to an inaccurate training failure rate reported for newly hired controllers. FAA’s metrics for measuring the effectiveness of the controller training program do not provide a complete picture because they include controllers who have not completed their initial training. For example, if there are 100 controllers in the training program and 9 of those controllers fail or leave, FAA reports an attrition rate of 9 percent. This produces unrealistic results because some of the remaining 91 in-progress controllers may also leave the program at a later time. Accurate training data are necessary so that FAA can adequately prepare new hires to replace retiring veteran controllers, assign new hires to the appropriate level and type of facility, and adjust its training program when warranted. OIG's recommendation focuses on steps FAA should take to measure and present a more complete picture of the effectiveness of its air traffic controller training program.

TI - Study of Aircraft Performance in Slippery Runway Conditions
AB - This proposal will investigate the use of Flight Data Recorder (FDR) data to determine actual real time runway slipperiness, and then effectively disseminate that information to other aircraft for use in decision making. It has been shows that instantaneous determination of the runway friction coefficient is possible and accurate with aircraft equipped with high frequency flight test data acquisition systems. It is though that this methodology could be extended to use in an algorithm using existing FDR data. With that, the landing aircraft could compute the runway slipperiness during the current landing. This data, plus trending data, could then be conveyed to the aircraft on approach for a go, no-go decision based upon accurate and timely information.

AB - The Federal Aviation Administration (FAA), with the cooperation of the National Park Service (NPS) and assistance of the U.S. Department of Transportation, John A. Volpe National Transportation Systems Center (Volpe Center) is developing Air Tour Management Plans (ATMP) for all national parks with commercial air tours, with the exception of the Grand Canyon National Park (GCNP), tribal lands within or abutting the GCNP, air tour operations flying over or near the Lake Mead National Recreation Area solely as a transportation route to conduct an air tour over GCNP, Rocky Mountain National Park, and national park units located in Alaska. An important area of technical support is the determination of representative baseline ambient sound levels for the study parks. During the summer (July – August 2009) and winter (January – February 2010), the Volpe Center conducted baseline ambient sound level measurements in Point Reyes National Seashore. Approximately one month of acoustical and meteorological data were measured at four sites throughout the park. This document summarizes the results of the noise measurement study.

AB - This report presents the latest results of research conducted at the Volpe Center on improving air traffic demand predictions and enhancing the Traffic Flow Management System (TFMS) Monitor/Alert function for identifying potential congestion at National Airspace System (NAS) elements such as airports, sectors and fixes. New approaches are presented for improving the way that TFMS determines if a sector is alerted. The deterministic demand pattern approach as well as the probabilistic weighted average approach have the advantage of being a smaller change from the traditional and long accepted way of doing business, while the fully probabilistic approach has the advantage of providing a more satisfactory way of looking at demand. The Federal Aviation Administration can now compare these approaches to the current approach and determine which is more attractive for the long run. If one of the new approaches is deemed desirable, additional work would be needed to flesh the proposals out into fully operational tools.

TI - U.S. Airline Transport Pilot International Flight Language Experiences, Report 6: Native English-Speaking Controllers Communicating With Non-Native English-Speaking Pilots
PY - 2011/03
SP - 36p
AB - In 1998, the International Civil Aviation Organization (ICAO) took a heightened interest in the role of language in airline accidents. Member states agreed to take steps to ensure air traffic control personnel and flight crews involved in flight operations where the use of the English language is required were proficient in conducting and comprehending radiotelephony communications in English. Since then, ICAO developed its English language requirements and urged its members to document their English Language Proficiency (ELP) test implementation plans by March 8, 2008. This report is a compilation of written responses and comments by a group of 48 U.S. pilots of their difficulties in international operations. There were 12 international U.S. pilots from American, Continental, Delta, and United Airlines. In this report, the pilots’ responses to questions 54-59 and their comments from discussions of those questions with 2 interviewers are presented as a compiled narrative. The authors derived 5 recommendations from these interviews. (1) Research is needed to determine the optimal speech rate for ATC messages. (2) ATC messages must be delivered using standard ICAO terms and phraseology. (3) Graphic and text representations of taxi clearances, route clearances, and route modifications should be made available to pilots on the flight deck as stand-alone messages. (4) Research is needed to identify how controllers communicate nonstandard situations (e.g., maneuvering around thunderstorms, traffic conflicts, delays). (5) Research is needed to determine the extent to which the absence of party-line information has on situational awareness and safety prior to takeoff and landing as pilots attempt to discern the intentions (and potential threat) of other pilots (especially those less proficient in English).

TI - Use of a High-Resolution Deterministic Weather Forecast for Strategic Air Traffic Management Decision Support
PY - 2011/02
SP - 27p
AB - One of the most significant air traffic challenges is managing the National Airspace System (NAS) in a manner that optimizes efficiency and mitigates avoidable delay, while maintaining safety, when convective weather is present. To do this, aviation planners seek to develop strategic air traffic management (ATM) plans and initiatives that anticipate weather constraints 2-8 hours in the future and identify options and alternatives for efficient operations during the off-nominal NAS conditions. In support of strategic planning, traffic managers currently conduct bi-hourly Strategic Planning Telcons and devise weather impact mitigations plans using the human-generated Collaborative Convective Forecast Product (CCFP). However, most operational decision-makers agree that the quasi-deterministic CCFP "polygons" (accompanied by a "low/high" forecast confidence rating) lack the granularity and temporal resolution to adequately support efficient strategic ATM plans and decisions. Moreover, traffic managers also assert that probabilistic forecasts of convective weather likelihood, while helpful in highlighting regions of possible airspace disruptions, generally lack the ability to resolve specific weather characteristics pertinent to strategic planning. MIT Lincoln Laboratory, NCAR Research Applications Laboratory, and NOAA Earth Systems Research Laboratory have collaborated to develop a high-resolution, rapidly updating 0-8 hour deterministic precipitation and echo tops forecast, known as CoSPA, to aid operational decision-makers in developing strategic plans for weather impact mitigation. In the summer of 2010, a comprehensive field study was conducted to assess potential benefits and the operational performance of CoSPA in the context of strategic ATM planning. The data were gathered by simultaneous real-time observations of I5 FAA and airline operations facilities during 15 convective weather impact days affecting the Northern Plains, Great Lakes, and East Coast regions of the NAS. CoSPA field evaluation results will be presented to demonstrate the various ways aviation planners have utilized the increased spatial and temporal resolution of CoSPA - the ability of CoSPA to resolve storm structure and refine forecasts with high update rates - to make more detailed assessments of potential weather impacts and to determine the subsequent need for airspace management initiatives. Results will also be presented that highlight CoSPA enhancement needs, primarily related to forecast uncertainty, that would improve the operational effectiveness of CoSPA-derived weather impact mitigation plans. Finally, opportunities to translate CoSPA deterministic forecasts into integrated weather-ATM decision support for specific strategic planning tasks will be discussed.

TI - Performance Assessment of a Radar-Based Foreign Object Debris Detection System
PY - 2011/02//Final Report
SP - 43p
AB - In 2004, the Federal Aviation Administration (FAA) Airport Technology Research and Development Team initiated a research program to conduct a performance assessment of the QinetiQ, Ltd. Tarsier Foreign Object Debris (FOD) detection radar system. The purpose of this assessment was to identify key operational characteristics and limitations of the system at an active air carrier airport, including the system’s ability to detect objects of various shapes, sizes, and materials at all locations on the runway surface. The system’s ability to detect FOD during both nighttime and daytime conditions, in periods of sun, rain, mist, fog, and in light and heavy snow was also assessed. In January 2005, the FAA developed plans for a comprehensive performance assessment of the technology at the Providence T. F. Green International Airport. Installation of the Tarsier system was completed in April 2007. Extensive data collection campaigns were conducted from June 2007 to March 2008. At the conclusion of the data collection process, the FAA had sufficient data to conclude the performance assessment. The QinetiQ Ltd. Tarsier FOD detection radar system was found to detect the necessary objects of various shapes, sizes, and materials on the runway surface and was able to perform satisfactorily in nighttime, daytime, sun, rain, mist, fog, and snow conditions, as required by FAA Advisory Circular 150/5220-24, “Airport Foreign Object Debris (FOD) Detection Equipment.”

TI - European and U.S. Perspectives on the Sharing and Integration of Weather Information into ATM Decisions
PY - 2011/02
SP - 6 p
AB - Weather is a major source of operational air traffic delays, accounting for 25 to 70% of all delays dependent of the geographical region. In today 's air traffic management (ATM) systems, a variety of weather information is available to help tactical and strategic planners better anticipate weather events that impact airspace capacity. Regretfully, the information is not always shared among all the stakeholders involved or well integrated into the existing ATM environment. This paper describes the high-level concepts for an improved sharing and integration of weather information into air traffic management decisions, as well as the current state and anticipated capabilities or the underlying information management infrastructure.

TI - Handbook for the Selection and Evaluation of Microprocessors for Airborne Systems
PY - 2011/02//Final Report
SP - 60p
AB - This handbook provides research information intended to help aerospace system developers and integrators and regulatory agency personnel in the selection and evaluation of commercial off-the-shelf microprocessors for use in aircraft systems. This handbook is based on the cooperative research accomplished by contributing members of the aerospace industry and the Federal Aviation Administration (FAA) as part of the Aerospace Vehicle Systems Institute Microprocessor Evaluations Projects 1 through 5. The project objectives were to (1) identify common risks of using systems-on-a-chip (SoC) and mitigation techniques to provide evidence that they satisfy regulatory requirements and (2) evaluate existing regulatory policy and guidelines against the emerging characteristics of complex, nondeterministic microprocessors and SoCs to support the certification of aircraft and qualification of systems using these devices. Complex aircraft system development requires more robust consideration of system failure and anomaly detection, correction, and recovery. The safety net approach identified in this handbook also may provide a means to reduce the growing difficulties and costs of design assurance for highly integrated, complex, nondeterministic airborne electronic hardware and software within aircraft systems and reduce the labor burden for FAA regulation compliance and design assurance. The safety net approach documented in this handbook is consistent with current FAA policy and guidelines.

TI - Aviation Child Safety Device Performance Standards Review
PY - 2011/02//Final Report
SP - 22p
AB - The design and performance requirements for Child Restraint Systems (CRS) in TSO-C100b and SAE AS5276/1 were developed to enable proper restraint of infants and small children traveling on transport airplanes. They complement and extend those in the Federal Motor Vehicle Safety Standard for Child Restraint Systems (FMVSS-213), which, prior to their development, were the only approval means for CRS used on aircraft. Development of CRS able to comply with the aviation standards has proven challenging, as the test requirements call for a combination of worst-case belt anchor location, belt tension, and seat cushion properties/dimensions that were typical at the time the specifications were written. These parameters no longer appear to be representative of the majority of transport airplane seats. As such, difficulty complying with the standards based on these test parameters may be inadvertently hindering the availability of aviation-specific CRS. Aviation-specific CRS, now commonly referred to as Aviation Child Safety Devices (ACSD), have been recently developed that provide upper torso restraint for forward-facing children. Alternative regulatory procedures have been adopted for certification of these devices, requiring demonstration of an equivalent level of safety with TSO-approved devices. Revision of the regulatory requirements in order to accommodate these new devices included removal of the explicit requirement for these systems to meet FMVSS-213. This action has inadvertently removed some applicable requirements that are not duplicated in the TSO. Such requirements include: design specifications for occupant support surfaces, belt/buckle strength and durability tests, and defined occupant restraint configuration, geometry, and adjustment range. In addition, FMVSS-213 has been revised significantly since TSO-C100b was written, improving several aspects that could benefit existing aviation standards and provide a safety benefit for ACSD. These include use of advanced test dummies, enhanced test dummy preparation and positioning procedures, improved head injury assessment, and better CRS installation procedures. Analysis of AS5276/1, TSO-C100b, FMVSS-213, and the current seat population in the U.S. transport airplane fleet suggests that revisions to both the Aerospace Standard and the TSO based on technological evolution, improvements to test equipment, and test procedures that are more representative of the aircraft environment would advance the development of ACSD while maintaining or improving child safety.

TI - Benzodiazepine Use in Pilots of Civil Aviation Accidents: 1990-2008 Toxicology and Autopsy Findings
PY - 2011/02//Final Report
SP - 14p
AB - Benzodiazepine medications have a long history of abuse. They are categorized as central nervous system depressants, and there are currently 15 different benzodiazepines prescribed in the United States and an additional 20 in other countries. The side effects of these medications include drowsiness, dizziness, decreased alertness, and/or memory loss, which can lead to impairment and a decreased ability to properly control an aircraft. The presence of these medications in postmortem specimens of aviation accident victims can help determine the cause of the accident and, potentially, result in serious legal consequences. The Civil Aerospace Medical Institute (CAMI) is in a unique position because a medical history is available to investigators for most certified pilots. With this in mind, the authors compared benzodiazepine compounds found following postmortem analysis with the available medical history for each victim. This evaluation was conducted to determine if these records supported the use of such medications or if the aviators were taking the compounds without the approval of their aviation medical examiners or possibly abusing the substances. In addition, a medical review of the autopsy records was also conducted. Toxicological information from analyses was retrieved from CAMI’s Forensic Toxicology Research Laboratory database. Case histories and accident information were obtained from the National Transportation Safety Board. Medical histories were obtained from the FAA’s medical certification database and CAMI’s autopsy team database. Over the examined time period (1990-2008), there were 6,062 fatal aviation accident cases received at CAMI, and 96 (~1.6%) pilots were found positive for a benzodiazepine. In ~74% of pilots found positive for benzodiazepine(s), it was determined that another compound was detected and more than one additional compound was often present. Fatal aviation accidents involving pilots who had taken a benzodiazepine compound prior to the flight are an infrequent event; however, concomitant use of more than one compound with benzodiazepines is common. This study highlights the use of benzodiazepine over the examined time period in the pilot community and presents a variety of demographic information about the pilots involved in such accidents.

This problem is akin to the difficult task of parallel parking for ground vehicles. However, whereas the latter task can be based on a simple kinematic model, DBMs for space vehicles require the use of more complex dynamic models due to the need to model the less precise actuators (e.g., thrusters) and to explicitly consider the inertia of the vehicle due to the lack of friction or environmental resistance.

TI - Robust Airborne Collision Avoidance through Dynamic Programming
PY - 2011/01/03/Project Report
SP - 118p
AB - The Traffic Alert and Collision Avoidance System (TCAS) uses an on-board beacon to monitor the local air traffic and logic to determine when to alert pilots to potential conflict. The current TCAS logic was the result of many years of development and involved the careful engineering of many heuristic rules specified in pseudocode. Unfortunately, due to the complexity of the logic, it is difficult to revise the pseudocode to accommodate the evolution of the airspace and the introduction of new technologies and procedures. This This report summarizes recent advances in computational techniques for automatically deriving the optimal logic with respect to a probabilistic model and a set of performance metrics. Simulations demonstrate how this new approach results in logic that significantly outperforms TCAS according to the standard safety and operational performance metrics.

Yet, limited information is readily available to airport operators regarding the factors that should be considered as changes occur to the maintenance, administration, or operation of the airport or to the available technology itself. The Airport Operators Council (AOC) wishes to identify issues related to IT that could benefit from applied research and be immediately put into practice upon completion. The Airport Cooperative Research Program (ACRP) has facilitated a special discussion for practitioners with interest and responsibility for the oversight of IT at airports. The objective of this discussion was to identify and develop a handful of research ideas related to IT and impacting airports that could benefit from ACRP research. Participants outlined the need, objective, and preliminary scope of the research ideas that were discussed.

However, unlike MPC, it optimizes uses sampling and A*-type optimization, which enables it to avoid local minimum and be used for real-time planning and control.

TI - Spaceflight Crew Medical Standards and Participant Acceptance Criteria
AB - The three objectives for this research project are: (i) development of recommendations for the medical standards for suborbital and orbital space vehicle crew members; (ii) development of recommendations for passenger acceptance criteria for suborbital and orbital space flight; and (iii) development of a model passenger 'Informed Consent' document for use by space launch operators to convey the risks related to personal medical status to their passengers. The project will collect and review of the existing literature addressing pilot medical certification, passenger medical evaluation guidelines, and recommendations about testing and training for both crew members and passengers. The project will convene a working group of previous authors of these documents, experts in space medicine and physiology, operational support personnel, training experts, and safety professionals to draft a consolidated set of recommendations for the medical certification of crew members, medical clearance of passengers, and training procedures. The project will conduct a study of the information that is required for passengers to complete an 'Informed Consent' declaration. In addition to the content of an 'informed consent' document, we will analyze and test the language reading level most appropriate for these forms to be easily understood by both individuals with English as their primary language and those for whom English is a second language.

TI - Ultra High Temperature Composites for Thermal Protection Systems
AB - Ultra high temperature ceramics (UHTCs) are a class of ceramics that are physically and chemically stable at temperatures above 2400°C and have melting temperature above 3200°C. Potential applications of these materials include components for leading edges and nose cones of hypersonic missiles and vehicles, kinetic energy interceptors, advanced ceramic engine components, re-entry vehicles, and as TPS for rocket thrust nozzles, etc. The research team will develop composites of UHTC top layer (e.g., ZrB2-SiC) and PZT piezoelectric/ZrO2 chemical sensing/Polymer Derived Ceramic (PDC) bottom layer which would allow to perform temperature, oxygen content, and stress sensing. While the top layer is highly oxidation-resistant at elevated temperatures, the bottom layer can sense mechanical and thermal stresses, as well as provide an input on the oxidation status of the upper ZrB2 UHTC layer. Thus UHTC composites with multifunctional structures will be developed. The team proposes to utilize a rapid processing scheme called spark plasma sintering (SPS) method that can sinter powders within 5 min at elevated temperatures and simultaneously provide a gradient in the temperature profile so that ceramics and sensor materials (with piezoelectric properties) can be sintered simultaneously to form multifunctional materials as desired. Hot isostatic pressing along with magnetron sputtering will be also used for multilayered materials' manufacturing. The proposal focuses on development of many such multifunctional systems with different combination of materials, and will investigate fundamental issues of processibility, microstructure development, interfacial characteristics, and mechanical performance.

PY - 2011/01
SP - 59p
AB - Currently, Integrated Noise Model (INM) and Aviation Environmental Design Tool (AEDT) do not use spectral data below 50 Hz in their noise computations. However, helicopter rotor rotational noise is dominant below 50Hz, with a fundamental frequency at the blade-pass frequency (BPF) and harmonics at integer multiples of BPF. Noise data for several helicopters have been measured for inclusion in the INM/AEDT database with expanded spectral data down to 12.5 Hz. The purpose of this effort is to determine what effects, if any, inclusion of low frequency data will have on resulting noise modeling. The results of which would determine if and how an expanded-spectra capability should be included in AEDT.

AB - Georgia’s airports are a major catalyst to the state’s growing economy. In order to better understand the economic benefit of Georgia’s airports to the economy, the Georgia Department of Transportation completed this study to quantify the economic contribution of the state’s airport system. The total economic contribution of Georgia’s 104 public-use airports is the sum of the on-airport businesses, the spending of visitors, and the additional activity of the recirculation of spending of on-airport businesses and visitors. Georgia’s airports contribute significantly to the state’s economy, supporting 471,175 jobs, $17.8 billion in payroll, and $62.6 billion in statewide economic impact. Annually, aviation contributes significant revenue to the state’s general fund and local governments, providing nearly $137 million in revenue in 2009, a 37% increase from 2001 aviation-related tax revenues.

TI - FAA Aerospace Forecast, Fiscal Years 2011-2031
PY - 2011
SP - 106p
AB - The airlines have returned to profitability, and expectations are that that will continue throughout 2011. The good news is not limited to the United States alone. Indeed, the international market is recovering at an even faster rate. Previously, the FAA had projected that U.S. commercial carriers would serve a billion passengers by 2023. The activity of 2010 has pushed that milestone forward two years to 2021. As the economy continues to recover, passenger and operations totals also will continue to climb. Just as was the case last year, it is expected that international markets will again continue to grow faster than domestic markets. Large airports will continue to outpace their smaller counterparts. The FAA forecasts that the numbers of larger regional jets flying will increase, while most of the smaller regional jets are retired from the fleet. Substantial growth in both demand and activity is projected, and 550 million more passengers will be on U.S. carriers by 2031 than in 2010. Traffic—revenue passenger miles—will more than double over the next 20 years. On the general aviation front, the demand for products and services will continue to grow. With new business jets and products like light sport aircraft, activity in this segment of the industry is expected to continue to increase in the future. The forecast is not without risk. Environmental constraints could lead to reductions in demand. The volatility of fuel prices and the continued presence of congestion continue to loom. This document presents forecast highlights, a review of 2010 activity, and detailed forecasts and forecast tables for fiscal years 2011-2031.

TI - FAA Needs to Improve Risk Assessment Processes for its Air Transportation Oversight System
PY - 2010/12/16
SP - 36p
AB - The Federal Aviation Administration (FAA) uses its Air Transportation Oversight System (ATOS) to conduct surveillance of nearly 100 airlines. These airlines transport more than 90 percent of U.S. airline passenger and cargo traffic. The U.S. Department of Transportation Office of Inspector General (OIG) has consistently reported that ATOS is conceptually sound because it is data-driven and intended to target inspector resources to the highest risk areas. However, in 2002 and 2005, OIG reported that FAA needed to strengthen national oversight of ATOS to hold field managers more accountable for consistently implementing effective oversight practices. After hearings on the safety issues at Southwest, the Senate Committee on Science, Commerce, and Transportation and the House Committee on Transportation and Infrastructure requested that OIG review FAA’s oversight of the U.S. airline industry. As a result of the weaknesses identified in OIG's 2008 testimony, the Committees asked OIG to determine if similar oversight weaknesses existed elsewhere in the system. Accordingly, OIG's audit objectives were to determine (1) whether FAA has completed timely ATOS inspections of air carriers’ policies and procedures for their most critical maintenance systems; (2) how effective ATOS performance inspections have been in testing and validating that these critical maintenance systems are working properly; and (3) how well FAA implemented ATOS for the remaining Part 121 air carriers and what, if any, oversight challenges FAA inspection offices face. Three areas were identified where FAA could improve its management and oversight of ATOS: timely inspection of policies and procedures for critical maintenance systems; assessments of whether or not critical maintenance systems were performed as intended; and effective implementation of ATOS.

TI - FAA Needs To Implement More Efficient Performance-Based Navigation Procedures and Clarify the Role of Third Parties
PY - 2010/12/10
SP - 26p
AB - On December 10, The U.S. Department of Transportation's Office of Inspector General (OIG) issued its report on the Federal Aviation Administration's (FAA) oversight of new flight procedures using Area Navigation (RNAV) and Required Navigation Performance (RNP) and its use of third parties to develop them. These technologies are key building blocks for the Next Generation Air Transportation System and could provide shorter, more direct flight paths; improved airport arrival rates; enhanced controller productivity; fuel savings; and reduced aircraft noise. OIG conducted this review at the request of the Chairman of the House Subcommittee on Aviation, who stated that a clear understanding of third-party roles is needed before they can be expanded. Overall, OIG found that the role of the two third parties FAA has approved to develop RNP procedures remains unclear, as well as FAA's strategy for implementing timely, high-value routes using in-house resources. FAA has also not fully established an oversight program for third parties, defined the staffing levels needed to oversee them, or finalized key guidance to industry on qualifications to become a third-party developer. OIG made eight recommendations to help FAA effectively implement and coordinate RNAV/RNP procedures and establish an oversight program for third parties. Overall, FAA's response met the intent of most of OIG's recommendations; however, OIG has requested that FAA provide additional clarifying information for three of them.

TI - En Route Data Communications: Experimental Human Factors Evaluation
PY - 2010/12//Technical Report
SP - 183p
AB - Data Communication (Data Comm) is one of the key enablers required for the implementation of the Next Generation Air Transportation System (NextGen) Plan. NextGen addresses increasing air traffic levels and complexity for 2015 and beyond (Joint Planning and Development Office, 2007). This report presents the experimental evaluation of Data Comm between en route controllers and pilots as an alternative to voice communication. The authors conducted the evaluation using an augmented emulation of the En Route Automation Modernization (ERAM) system. In 2009, the Federal Aviation Administration (FAA) has started to replace the current Display System Replacement and Host Computer System with ERAM. The authors recorded and analyzed system, controller performance, and controller self-report data. They also recorded and analyzed controllers’ eye movements and oxygenation levels of the prefrontal cortex using functional near infrared technology. The results showed that the most useful Data Comm interface was the Human-Machine Interface that combined keyboard, template, and graphical capabilities. An increase in the proportion of the aircraft that were Data Comm capable reduced the frequency of voice communications and lowered controller workload. Data communication failure of individual aircraft did not affect controller performance, but partial or full system failure increased the number of voice communications and workload. For the aircraft that did not have an integrated Flight Management System (FMS), controllers did not opt to use voice communications more often than using Data Comm, but integrated FMS reduced their workload. The analysis did not find a difference between first-come, first-served and best-equipped, best-served policies. On the basis of these results, recommendations are presented for the NextGen Data Comm.

PY - 2010/12//Technical Report
SP - 81p
AB - The Separation Management Project is part of the Federal Aviation Administrations (FAA) Next Generation Air Transportation System (NextGen) Plan. Human factors researchers from the FAA's William J. Hughes Technical Center conducted a human-in-the-loop simulation to investigate variable lateral separation standards in the en route environment. Twelve Certified Professional Controllers participated in the study. The authors simulated reduced separation requirements (i.e., 3 miles) using a single sensor radar site adaptation as well as for aircraft with either Automatic Dependent Surveillance-Broadcast or Performance-Based Navigation equipment. The authors simulated increased separation (i.e., 10 miles) for Unmanned Aircraft Systems. In addition, the authors simulated variable wake turbulence separation requirements for the Airbus 380 and Very Light Jets. The authors also developed a set of support tools to assist the controllers in using the variable separation procedures. The authors identified several human factors issues, and the results are discussed in terms of the automation requirements necessary to support the variable separation concept.

TI - U.S. Airline Transport Pilot International Flight Language Experiences, Report 5:
Language Experiences in Native English-Speaking Airspace/Airports
PY - 2010/12//Final Report
SP - 28p
AB - In 1998, the International Civil Aviation Organization took a heightened interest in the role of language in airline accidents. Member states agreed to take steps to ensure air traffic control personnel and flight crews involved in flight operations in airspace where the use of the English language is required were proficient in conducting and comprehending radiotelephony communications in English. This report is a compilation of written responses and comments by U.S. pilots from American, Continental, Delta, and United Airlines of their difficulties in international operations. In this report, the pilots’ responses to questions 46-53 are presented as a compiled narrative. Their responses had eight major thrusts from which the authors derived the following five recommendations: (1) Adopt a standard dialect for use in ATC communications. (2) All trainees and current certified professional controllers successfully complete instruction and training in the principles of voice production and articulation as it relates to ATC communication. (3) Define an optimal rate of speech for use by certified professional controllers when communicating with pilots. Research is needed to provide guidance on the optimal rate of speech for different populations of speakers – U.S., Foreign. (4) Develop new standard phraseology for non-routine events. Generally, the controller needs to have the pilot answer one question, “What do you need from me?” The controller would coordinate the appropriate actions to provide the pilot with what is needed. (5) Controllers should be discouraged from using local jargon, slang, idiomatic expressions, and other forms of conversational communications when transmitting messages to pilots. Although colorful and fun, they have no place in air traffic control and diminish situational awareness, can lead to requests for repeat, and otherwise disrupt information transfer.

TI - The Illumination of Aircraft at Altitude by Laser Beams: A 5-Year Study Period (2004–2008)
PY - 2010/12//Final Report
SP - 16p
AB - INTRODUCTION: Laser illuminations of aircraft in navigable airspace have concerned the aviation community for over a decade. The principal apprehension is the effect laser illumination may have on flight crew personnel performing landing and departure maneuvers, where procedural requirements are critical. This study examines the frequency of aviation-related laser incidents by altitude of occurrence. METHODS: Event reports of aircraft illuminated by high-intensity light sources have been collected from various sources and entered into a database maintained by the Federal Aviation Administration’s Civil Aerospace Medical Institute. Reported events of laser exposure of civilian aircraft for a 5-year period (January 1, 2004 to December 31, 2008) were collated and analyzed. RESULTS: A total of 2,492 laser events occurred in the U.S. during the study period. The cockpit environment was illuminated by laser beam in 1,676 (67.3%) events, and altitude information was provided in 1,361 (81.2%) of these reports. At altitude levels associated with the FAA’s Laser- Free Zone (0–2,000 feet), cockpit illuminations increased from 12.5% to 26.7% for the period, while the percentage for Critical Flight Zone equivalent altitudes (>2,000–10,000 feet) decreased from 87.5% to 58.4%. For the period, green laser light was reported in 92% of the events where color was identified. CONCLUSION: The increasing percentage of aircraft laser illuminations reported at or below 2,000 feet that involve green laser light may represent an escalating threat to aviation safety. Low-flying aircraft, which may not be within currently established flight hazard zones around airports, need protection due to their increased vulnerability to laser illumination and their close proximity to obstacles and terrain.

TI - Postmortem Concentrations of Tramadol and O-Desmethyltramadol in 11 Aviation Accident Fatalities
PY - 2010/12//Final Report
SP - 12p
AB - Tramadol is a centrally acting analgesic used to treat moderate-to-severe pain. Side effects of this medication include dizziness, confusion, drowsiness, seizures, and respiratory depression. Any of these side effects could negatively affect a pilot’s performance and become a factor in an aviation accident. Due to the severity of aviation accidents, blood samples are often not available, and frequently, only tissue specimens are available for analysis. Therefore, understanding the distribution of a drug throughout all fluids and tissues of the body is important when trying to interpret drug impairment and/or intoxication. Our laboratory has determined the distribution of tramadol and its main active metabolite, O-desmethyltramadol, in various postmortem tissues and fluids obtained from 11 fatal aviation accident cases. Whole blood tramadol concentrations obtained from these 11 cases ranged from 81-2720 ng/mL. When available, 10 specimen types were analyzed for each case, including blood, urine, vitreous humor, liver, lung, kidney, spleen, muscle, heart, and brain. Distribution, expressed as specimen/blood ratio, for tramadol was 69 ± 74 in urine, 2.58 ± 3.26 in vitreous humor, 4.90 ± 3.32 in liver, 3.43 ± 2.31 in lung, 3.05 ± 1.49 in kidney, 5.15 ± 2.66 in spleen, 1.18 ± 0.85 in muscle, 2.33 ± 1.21 in brain, and 1.89 ± 1.01 in heart. Distribution coefficients obtained had coefficient of variations (CV) ranging from 49-126%. With such large CV’s, the distribution coefficients have little use in predicting blood concentrations from the analysis of a tissue specimen. This study indicates that tramadol concentrations undergo significant postmortem changes.

TI - Physiological Equivalence of Normobaric and Hypobaric Exposures of Humans to 25,000 Feet
PY - 2010/12//Final Report
SP - 20p
AB - Introduction: Skepticism exists whether normobaric and hypobaric hypoxic exposures are equivalent. The authors have evaluated if physiological differences between the two environments would translate into actual differences in hypoxia symptoms. Methods: The authors exposed 20 subjects to 5-min 25,000 ft (7620 m) equivalent environments in an altitude chamber and then in a ground-level portable reduced-oxygen training enclosure (PROTE). Heart rate and hemoglobin oxygen saturation (SAO2) were continuously monitored. Alveolar gas samples were collected at 1-, 3-, and 4-min elapsed time. Subjects completed hypoxia symptom questionnaires at the same time points. Results: Mean 4th min alveolar oxygen tension (PAO2 ), alveolar carbon dioxide tension (PACO2 ), and respiratory quotient (RQ) differed significantly between the chamber and PROTE. Declines in SAO2 appeared biphasic, with steepest declines seen in the first minute. Rates of SAO2 decline over the 5-min exposure were significantly different. Heart rate was not different, even when indexed to body surface area. Mean number of hypoxia symptoms between hypobaric and normobaric environments after 1 min were significant. However, the temporal pattern of symptom frequencies across subjects between the chamber and PROTE were similar. Conclusions: Alveolar gas composition, as well as arterial hemoglobin oxygen desaturation patterns, differed between a ground-level and hypobaric exposure. Differences in mean number of hypoxia symptoms between hypobaric and normobaric environments after 1 min, but not at 3 and 4 min, coupled with similar patterns in symptom frequencies, suggest that ground-level hypoxia training may be a sufficiently faithful surrogate for altitude chamber training.

TI - Flight Attendant Fatigue Recommendation II: Flight Attendant Work/Rest Patterns, Alertness, and Performance Assessment
PY - 2010/12//Final Report
SP - 20p
AB - Impaired performance induced by fatigue may compromise safety in commercial aviation. Given the direct role flight attendants play in passenger safety, the U.S. Congress ordered a comprehensive examination of fatigue in cabin crew, including a field study of actual flight operations. This report provides an overview of the field study results, focusing on objective measures of sleep patterns and neurocognitive performance (Psychomotor Vigilance Test, PVT) over a 3-4 week period in 202 U.S.-based flight attendants of all seniority levels working for network, low-cost, and regional carriers embarking on domestic and international flight operations. On average, flight attendants slept 6.3 hr on days off and 5.7 hr on work days, fell asleep 29 min after going to bed, awoke four times per sleep episode, and spent 77% of each episode actually sleeping. After controlling for reserve status, gender, and age, junior-level flight attendants had the shortest sleep latencies on their days off. Those working international operations slept significantly less (4.9 hr vs. 5.9 hr) and less efficiently (75% vs. 79%), compared with their colleagues in domestic operations. All flight attendants exhibited significant impairments during pre-work PVT tests when compared to their own optimum baseline performance. Across the workday, regional flight attendants committed fewer premature PVT responses, junior-level participants produced significantly higher post-work reaction times, and those working international flights produced better pre-work reaction times but had a greater increase in lapses. These objective data are consistent with other shift work research and echo subjective survey findings across the U.S. flight attendant community. Additional planned analyses of this dataset may identify the precise operational variables that contribute to fatigue in cabin crew.

It leverages the development efforts of the National Aeronautics and Space Administration (NASA) Surface Management System (SMS) and provides a road map to the development of a collaborative Surface Traffic Management (STM) system with tools necessary to achieve a fully collaborative surface environment. This environment is required to safely enable the airport capacity necessary for operations in 2025 and to enable trajectory based operations on the airport surface. The NextGen Concept of Operations, authored by the Joint Planning and Development Office (JPDO), states that "4DTs [four-dimensional trajectories] may be used on the airport surface at high-density airports to expedite traffic and schedule active runway crossings." Achieving this vision will require a series of advances in procedures, supporting automation systems, and collaboration between air traffic control (ATC) and the flight operators.

PY - 2010/11//Final Report
SP - 41p
AB - The U.S. Department of Transportation, Research and Innovative Technology Administration, John A. Volpe National Transportation Systems Center, Environmental Measurement and Modeling Division (Volpe), is supporting the aircraft noise certification initiatives of the Federal Aviation Administration (FAA), Office of Environment and Energy (AEE) by preparing the “Validation Protocol for Digital Audio Recorders Used in Air-craft-Noise-Certification Testing” (Validation Protocol). As analog and digital tape-based recording devices are becoming obsolete, this Validation Protocol has been developed for applicants requesting permission from FAA/AEE to conduct aircraft noise certification testing using non-tape-based recorders. Because of the significant differences between non-tape-based recording devices and all preceding technologies, this Protocol establishes a set of procedures for testing and evaluating the performance of non-tape-based digital audio recorders proposed for aircraft noise certification use. If using any of the digital audio recording devices covered by the scope of this document, it is recommended that an applicant perform tests to evaluate the characteristics of the re-cording device in accordance with the guidance in the Validation Protocol to demonstrate compliance with part 36 Title 14 of the Code of Federal Regulations (Part 36) and Inter-national Civil Aviation Organization Annex 16 Volume I (ICAO Annex 16).

TI - Effects of Video Weather Training Products, Web-Based Preflight Weather Briefing, and Local Versus Non-Local Pilots on General Aviation Pilot Weather Knowledge and Flight Behavior, Phase 3
PY - 2010/11//Final Report
SP - 20p
AB - The primary purpose of Phases 1 and 2 of this research was to test the effects of video weather training products on weather-related risk-taking. During the investigation, two unexpected observations were made: (1) Despite specific instructions to fly visual-flight-rules-only (VFR), nine of 50 Phase 1 pilots spent more than 10 min in simulated instrument meteorological conditions (IMC), plus three of those nine repeated that behavior in Phase 2; (2) Whole-group (N=50) weather knowledge test scores were significantly lower (19%, p<.001) than average FAA certification exam scores obtained by freshly licensed pilots, implying knowledge decay over time. To assess if any of the IMC violations were willful (rather than inadvertent), the authors sent a brief questionnaire to the nine pilots of interest. Five responded. After analysis, the leading explanation seemed that their flight profiles were consistent with preflight terrain avoidance planning (TAP). These pilots seemed determined to fly straight and level above the highest known obstacle, even if that obstacle was distant and TAP altitude meant flying initial VFR-into-IMC. The average group decline in certification exam scores was equally significant from a logical standpoint. Since knowledge retention tends to be a function of knowledge relevancy, if FAA test questions were uniformly relevant to real-world weather encounters, we would expect pilots’ scores to increase with experience, not decrease. Since experience tends to increase with time, this should offset the normal decay process of forgetting. However, this study shows that it did not. This was consistent with pilot anecdotes that FAA test questions often seemed, to them, “trick questions,” or otherwise based on tasks that pilots rarely do and conditions rarely encountered. This suggests ways to improve FAA exams: (1) Screen existing questions for real-world relevancy, eliminating those based solely on rote learning; (2) Scale the relative number of weather-test items to the relative hazard and/or encounter frequency of real-world weather types (dangerous and common weather types deserve relatively more test questions); (3) Computerize the testing procedure; (4) Require pilots to pass a certain percentage of weather questions. Critics may argue that the relatively small percentage of weather-related questions on any given exam could make the test hard to pass for some individuals due to sampling error. However, this could be addressed by computerized adaptive testing, which presents harder questions to a candidate after correct answers, and easier questions after incorrect answers. Computerized adaptive testing quickly homes in on a candidate’s native ability level and self-terminates after reaching a preset reliability (e.g., 95%). Because adaptive tests tend to be more efficient (shorter and more reliable) than fixed-item tests, this would free up more testing time for weather-related items, making sampling error much less of a problem.

TI - Developing Proactive Methods for General Aviation Data Collection
PY - 2010/11//Final Report
SP - 28p
AB - Introduction: Over the last 20 years, nearly 40,000 general aviation (GA) aircraft were involved in accidents, roughly 20% of which were fatal. To address this safety concern, scientists have often relied on accident data. Because of the rare nature of accidents, commercial aviation incident and near miss data may prove to be useful sources of safety information. In one such study, the National Transportation Safety Board interviewed GA pilots that were flying near a weather-related accident in pursuit of a different perspective than that of the accident pilot. Interviewing GA pilots about their own weather-related event may provide similar benefits. Method: To understand factors leading GA pilots to encounter adverse weather conditions, pilots involved in an adverse weather encounter were interviewed using a one-hour structured interview. The interview was developed using surveys utilized by National Aeronautics and Space Administration and the Federal Aviation Administration (FAA). In total, 27 pilots who experienced an adverse weather encounter were interviewed, of which 25 were included in the final analysis. Results: Previous studies conducted by the FAA and others found many GA accidents involving flight into adverse weather were categorized as a willful disregard for the rules and regulations of safety; violations as defined by the Human Factors Analysis and Classification System. Contrary to what the accident record seems to suggest, flight into adverse weather may also be influenced by the lack of appreciation/understanding of the hazards associated with adverse weather. Perhaps some encounters with adverse weather were motivated by outside influences or exacerbated by some manner of mechanical failure that may have led to the willful acceptance of unnecessary hazards. Conclusions: These data suggest that current beliefs surrounding flight into adverse weather by GA pilots may be incomplete. The data presented here suggest that additional effort should be placed in training, both ab initio and recurrent. Emphasis should be placed on ensuring a full understanding of the adverse impact of weather, including the recognition of instrument meteorological conditions, icing, convective events, etc. Likewise, with the proliferation of commercial weather products and on-board weather equipment, it may be time to move toward some form of standard weather package that all pilots would review before flying.

TI - The AIRWOLF Tool to Support En Route Controller Weather Advisories.
PY - 2010/10//Technical Report
SP - 23p
AB - In current en route operations, controllers integrate weather information and traffic data manually while providing advisories to pilots. Previously, the authors developed a weather support tool called Automatic Identification of Risky Weather Objects in Line of Flight (AIRWOLF) that (a) detects conflicts between aircraft and hazardous weather, (b) alerts the controller, and (c) generates automatic weather advisories. Automated weather advisories based on the AIRWOLF tool could support the controller by eliminating the need for a manual integration of traffic and weather data, thereby reducing the total time it takes a controller to provide an advisory. To test this hypothesis, the authors evaluated the AIRWOLF weather support tool in a part-task simulation. During the simulation, participants responded to the AIRWOLF tool alerts by providing weather advisories via radio or data link communication. The results showed that it took, on average, 27 seconds to manually compose and transmit a weather advisory by radio (currently used in Air Traffic Control). When participants used automatic weather advisories, it reduced the advisory time by approximately 7 seconds. When participants used data link communication with the AIRWOLF tool, the weather advisory times were reduced by as much as 16 seconds. These results show that the AIRWOLF tool could reduce advisory time and support controllers for the safe, efficient, and strategic efforts required to handle adverse weather conditions in the en route environment.

AB - The Traffic Alert and Collision Avoidance System (TCAS) Verion 7 surveillance requirements were developed in the mid-1990s with the use of limited radar data. Recently, a more comprehensive radar data source has become available, enabling a thorough analysis of TCAS surveillance performance throughout the National Airspace System (NAS). This paper characterizes six high traffic terminal environments over three months. A busy one-hour period was selected from each location for density and equipage measurements. This paper then describes the use of a high fidelity simulation to characterize compared with the design requirements, including interference limiting specifications. The effect of TCAS surveillance activity on Air Traffic Control (ATC) ground radar performance is also investigated. Results indicate that the surveillance algorithms perform as intended and that TCAS has a minimal impact on ground radar. Areas of concern are noted for future investigations.

TI - Flight Crew Intervention Credit in System Safety Assessment. Evaluation by Manufacturers and Definition of Application Areas
PY - 2010/10//Final Report
SP - 38p
AB - According to current regulations for type certification of large commercial aircraft, certification credit may be taken for correct and appropriate action for both quantitative and qualitative assessments provided that some general criteria are fulfilled. According to the same regulations, quantitative assessments of the probabilities of flight crew errors are not considered feasible. As a consequence, the system designer is allowed to take 100% credit for correct flight crew action in response to a failure. Previous research indicates that this leads to an overestimation of flight crew performance. The goal of this research effort was to develop a method that would allow certification credit for good human factors design practice in certification regulations. This method consists of a scoring algorithm that combines key flight deck design characteristics into an overall level of certification credit for flight crew intervention in response to a system failure. Aircraft manufacturers applied the method to a selection of system failure cases, which provided feedback on the method, characteristics, and application areas. Seven options for implementation of this method in the design and certification process have been identified.

Transport Airplanes (Rudder Survey)
PY - 2010/10//Final Report
SP - 50p
AB - Following the AA587 accident, the National Transportation Safety Board requested that the FAA explore certain elements of transport aircraft and rudder usage, including but not limited to awareness that sequential full, opposite-rudder inputs (rudder reversals), even at speeds below the design maneuvering speed, may result in structural loads that exceed those addressed by Title 14 of the Code of Federal Regulations (CFR) part 25, § 25.1507. The Transport Directorate initiated a Web-based survey developed in conjunction with the FAA Civil Aerospace Medical Institute to survey the population of Transport Category Airplane Pilots’ (TCAP) understanding of the use of rudder and their experiences with rudder, both as the pilot flying and as the pilot not flying. The survey also explored TCAP’s experiences with upset, including magnitude and recovery. The survey further explored TCAP’s experience with rudder training, unusual attitude recovery training, and their perceptions of additional training needed. Additionally, the survey explored the issue of maneuvering speed and movement of rudder, aileron, and elevator controls. Survey results indicated: 1) Rudder is reported to be used more than the Rudder Survey Team expected; 2) Rudder is reported to be used or considered for use in ways not always trained and in ways not recommended by the manufacturers; 3) Erroneous and accidental inputs occur, and it is reasonable to believe that this will continue in the future; 4) Some respondents reported making pedal reversals (cyclic rudder-pedal commands); 5) Some respondents are not clear on appropriate use of rudder, and many felt they needed more training; 6) Wake vortex encounters were reported to be the most common initiator of upset; these were most likely to be reported in the approach phase; and 7) Respondents did not seem to be concerned with differences among control system designs across aircraft. Given these findings, a set of recommendations is suggested to guide further research.

TI - Measuring PM Emissions from Aircraft Auxiliary Power Units, Tires and Brakes
AB - Assessment of particulate matter (PM) emissions from aircraft engines and other emission sources at airports are growing in importance as demand for air travel grows. However, little or no data are available on APUs, GSE, and tire and brake emissions during landing operations. Without better information about PM emissions, airports will face increasing barriers to expansion. To address this lack of data on emissions from APUs, GSE, and tires and brakes, a measurement campaign for quantifying PM emissions at the source tailpipe and in the near field of these sources is needed. This research will initiate a high-quality multidimensional study of PM emissions from GSE, APUs, and tires and brakes coupling source emissions at the tailpipe/exhaust plane and in the near field to define specific source profiles. These high-quality multidimensional studies should include a thorough physical (e.g., size, number, mass) and chemical composition analysis at the emissions source and in the near field (<20m downstream). It may not be feasible to capture tire and brake emissions at the source on an active airport, in which case it may be necessary to determine this in brake and tire friction laboratories. Note: Measuring PM emissions from APUs, GSE, and aircraft tires and brakes will require cooperation with aircraft and GSE owners and operators. Such voluntary support from aircraft and GSE owners and operators may be difficult to obtain, given the current economic climate and limited resources available to devote to this volunteer effort.

TI - FAA’s Air Traffic Controller Optimum Training Solution Program: Sound Contract Management Practices Are Needed To Achieve Program Outcomes
PY - 2010/09/30
SP - 27p
AB - The Federal Aviation Administration (FAA) plans to hire and train nearly 15,000 new air traffic controllers through fiscal year (FY) 2018 to replace the large pool of air traffic controllers who were hired after the 1981 strike and are now retiring. In September 2008, FAA awarded a contract to the Raytheon Technical Services Corporation (Raytheon) to provide training support for new and existing controllers and to assist FAA in modernizing its controller training program. The contract for the Air Traffic Controller Optimum Training Solution (ATCOTS) is for a period of up to 10 years (with a 5-year base period and 5 option years) at a total potential cost of $859 million. Under terms of the contract, Raytheon provides classroom, laboratory, and simulator instruction; training support; course and curriculum development; and administrative and program support services at the FAA Academy and air traffic facilities nationwide. Key ATCOTS goals for controller training include reducing total cost and time, improving quality and consistency, and developing flexible training systems that can be adapted to new technologies—particularly those related to the Next Generation Air Transportation System (NextGen). In January 2009, it was requested that the Department of Transportation Office of Inspector General (OIG) review the ATCOTS program. The request stated that while ATCOTS could bring positive changes to FAA’s training program, given its importance, a better understanding of the financial and contractual aspects is needed. Accordingly, OIG's audit objectives were to determine (1) whether effective management and contract controls are in place to ensure program goals are achieved and (2) if the program has improved training methods currently provided to the controller workforce. It was found that, in designing and executing the ATCOTS program, FAA did not fully consider program requirements. As a result, FAA now faces significant challenges in achieving the program’s goals.

TI - Synthetic Speech and Visual Data Communication for Flight Deck Use
AB - The objective of this research is to address the human factors issues of implementing Data Comm with a synthetic speech component on the flight deck as a means of optimizing communications between air traffic controllers (ATC) and pilots. The research will specifically focus on how a synthetic speech system can reduce pilots' need to focus attention heads down on the flight deck, reduce workload, and enhance situation awareness. The researchers will also examine levels of conformity with a synthetic speech system compared to Data Comm only messages. The research will use Advanced Aviation Training Devices (AATD) and/or Flight Training Devices (FTD) that incorporate a visual data communication interface that uses the latest Data Comm message set for communications with ATC. In order to evaluate synthetic speech, the researchers will develop a prototype visual data communication interface, hereafter referred to as the visual digital display device, that pilots will use to respond to Data Comm messages in both text and synthetic voice will serve as an experimental apparatus for examining digital communication issues in a simulated flight setting.

Based on a review of envisioned NextGen technologies and their intended use as well as established design principles and perceptual processes, promising display locations and groupings will be identified and empirically evaluated for their performance effects in the context of simulation studies. Recommendations and guiding principles will be developed that support both the effective design and the certification of NextGen flight deck display suites. The findings from this project may also highlight the need for updates and modifications of existing advisories and guidance documents.

AB - Research into the characteristics of complex microprocessors and systems-on-a-chip revealed increasing difficulties in design assurance of airborne systems containing these commercial off-the-shelf devices. This was found to require system-level methods, including monitoring, fault or anomaly detection, and corrective actions based on resilient system architectures and system controls. This approach is accumulatively identified as safety nets. Phase 4 initiated the evaluation of simulation and test tools to aid in the safety net approach. It was determined that safety nets must be involved at multiple levels with aircraft systems. Phase 5 will further research the device characteristics and the safety net approach. A Federal Aviation Administration Handbook for the selection and verification of systems using these devices was planned in Phase 4 and will be implemented with the results from Phase 5.

AB - This document provides an overview of Electronic Flight Bag (EFB) systems and capabilities, as of June 2010. This document updates and replaces the April 2007 EFB Industry Review (Yeh and Chandra, 2007). As with the previous industry survey, the focus is on the human systems interface. The information for this report was gathered through industry contacts, demonstrations, websites, brochures, and trade journal reports. This report was conducted in support of the Federal Aviation Administration (AA), but the information is intended to be of use to anyone interested in EFBs. The report contains four sections. The first section provides an overview of the effort. The second contains tables summarizing the information collected from those manufactures who provide an integrated EFB system solution. The third provides details for products and services offered by EFB systems manufactures, i.e., those who develop physical EFB hardware and provide EFB software. The fourth contains detailed information for products offered by EFB software manufacturers who do not develop EFB hardware. Software manufacturers were classified into two categories: those who offer an integrated and customizable software package that integrates several functions/applications and those who provide commercial off-the-shelf software that has not been integrated, customized, or tailored for a particular EFB. References to FAA EFB regulatory and guidance material and links to Flight Standardization Board (FB) reports, which provide information regarding the operational suitability for particular EFB models are also included.

TI - Causes of General Aviation Weather-Related, Non-Fatal Incidents: Analysis Using NASA Aviation Safety Reporting System Data
PY - 2010/09
SP - 52p
AB - Adverse weather remains a major cause of general aviation accidents. However, weather alone is never the sole culprit. Searching for other salient causal factors, the authors turned to incident analysis. Incidents are less serious than accidents, but far more common, and have witnesses to better determine causes. The current research examined 100 GA weather-related incident reports made to the Aviation Safety Reporting System (ASRS) during 2005-06. With pilot permission, ASRS gathered additional data on nearly 300 variables related to possible root causes. The following factors seemed to constitute a problem for 5%, or more, of pilots: 1. Darkness (4 dusk +17 night = 21% of pilots). 2. Moisture affecting visibility (clouds, fog, rain, snow > 50%) and/or air movement affecting aircraft handling (thunderstorm, icing, turbulence > 25%). 3. Multiple weather factors experienced simultaneously (85%). 4. Failure to get a preflight weather briefing, or “briefing” with only a low-grade (non-aviation-oriented) source (5%). 5. Deterioration of weather forecast accuracy over time (66% correct forecasts at departure, decreasing to 37% correct at destination). 6. Weather that materialized worse than predicted (35%. This implicitly includes lack of en-route forecast updates). 7. Lack of weather-related training and experience (> 50%, non-instrument-rated and new instrument-rated pilots). 8. Inadequate equipment (less-experienced pilots tend to have less-capable airframes and avionics). 9. Ambulance missions (7%, particularly helicopter ambulance). 10. “Non-weather-related factors”: decision-making (26%), time pressure (21%), “get-home-itis” (9%), aircraft equipment problem (8%), fatigue (7%), distraction by passenger or crew (5%). In broad terms, this analysis reveals two major at-risk target groups with distinct training needs: (1) Non-instrument-rated pilots; and (2) Newly minted instrument-rated pilots.

TI - Guidebook for Airport Irregular Operations (IROPS) Contingency Planning
AB - Meeting customer core needs during Irregular Operations (IROPS) is a critical problem for airports, airlines, and aviation service providers. IROPS are events that disrupt optimized flight schedules and negatively impact the normal flow of passengers through the air transportation system. In the wake of the weather-related multi-hour disruptions in 2007 and 2008, several workshops (including the September 2007 DFW IROPS Workshop, the July 2008 DFW Regional Diversion Airport/Airline Workshop, and the January 2008 ACI-NA IROPS Workshop) were held to proactively address these challenges and set the stage for communication, collaboration, and coordination and identify best practices within the industry. These workshops identified potential actions for improvement, among which included: (1) Airlines, airports, government agencies, and other system partners should update contingency plans, and should include sufficient collaboration; (2) Communication among these parties should be collaborative, coordinated, and on-going; and (3) Service providers (e.g., concessionaires, ground transportation) should continually evaluate the level of services provided in meeting customer needs during IROPS. To address these actions, a national task force appointed by the Secretary of Transportation met over a period of 10 months and produced model contingency plan recommendations in November 2008. This task force included government employees, representatives of airlines, airports, and consumer groups. The task force produced a recommended Model Plan for Lengthy Airline Onboard Ground Delays. The U.S. Department of Transportation also established regulations for Enhancing Airline Passenger Protections, which requires air carriers to develop individual contingency plans at the large and medium hub airports they serve. Contingency planning for large, medium, and small airports, using a collaborative and coordinated approach among key airport stakeholders, is essential to address current and evolving aviation challenges that disrupt the normal flow of passengers through the air transportation system. Further research is needed to provide additional assistance in this area. The objective of this research is to prepare a practical airport guidebook for commercial passenger service airports of all sizes to develop, continually evaluate, and/or update their contingency plans for procedures pertaining to IROPS that may cause significant disruptions to customers. This research will assist aviation system partners in improving their response to customer care during a broad array of IROPS conditions and will devise a step-by step template in the form of an interactive CD for the preparation of contingency plans that include necessary communications, collaboration, and coordination to address customer needs. A specific focus on the needs of smaller airports will be included in the development of the guidebook.

TI - Role of the COE-CST in Encourage, Facilitate and Promote
AB - The current environment favors such initiatives conceptually, but the business case for them is difficult to close. Unless they have a specific interest in the hosted technology, commercial launch users are reluctant to give up even a few kilograms of launch mass at prices supportable by research institutions and small commercial startups. In recent research roadmapping effort, identifying and characterizing the space transportation market was identified as a priority research task for the Center of Excellence. In order to find a tractable focus area, the project took industry partners' suggestion of investigating secondary and hosted payloads (SHP's). SHP's represent a unique opportunity to achieve low cost access to space, yet are rarely used. The task will work to identify the barriers to SHP's and how they can be overcome.

AB - Project 38's goal is to provide insight into how typical dwelling envelopes affect indoor sound levels due to non-sonic boom aircraft noise. Many existing aircraft noise guidelines are based primarily on outdoor sound levels. However, human perception is largely based on indoor response. This study will leverage existing technologies in sound transmission to model the combined sound isolation of dwelling envelopes. The model will be whole-housed focused; that is, the research will focus on composite dwelling envelopes (walls + windows + roof, etc).

TI - Evaluation of Airport Emissions within State Implementation Plans
AB - Aviation is a growth sector in the United States. The growth of air traffic operations in the U.S. has resulted in an increase in traffic at the nation's major airports, accompanied by a corresponding increase in surface congestion and emissions. Of the Nation's 3,000 commercial service airports, only 158 are currently located in the Environmental Protetion Administration (EPA) designated nonattainment or maintenance areas (a concise list of these airports is located at: http://www.faa.gov/airports_airtraffic/airports/environmental/vale/). As EPA's emission control strategies for other non-aviation sectors take effect, the aviation emissions sources could become more pronounced both within the current Rate of Progress (ROP) emission inventories conducted for our Nation's poor air quality regions as well as the future forecasted State Implementation Plan (SIP) emission budgets. At the same time, the Federal Aviation Administration's (FAA's) Terminal Area Forecast (TAF) projects the growth of the U.S. aviation activities. How well do the individual SIP emission forecasts agree with the FAA's aviation activity TAF? Given that most SIP emission forecasts for aviation sources differ with the FAA's aviation activity TAF, the objective of this research is to develop recommendations and/or guidance for local and state agencies to better represent future airport emission sources in their SIP forecasts. This research will answer the following questions. What portion(s) of the individual SIP emissions budgets do airport sources represent? What are the forecasted out years of SIP attainment compliance? How were airport emission sources forecasted for these out years? How do the SIP emissions forecasts compare with the FAA's TAF activity forecast? If there is considerable difference between the two, what recommendations can be brought forth to improve the forecasted growth of airport emissions within the applicable SIP budgets to better align with the FAA TAF?

TI - Evaluating Terminal Renewal versus Replacement Options
AB - Most airport terminal facilities (e.g., terminal building, parking garages, and terminal roadways) are nearing the end of their useful life. In addition, the airline industry has significantly reduced capacity over the last few years to better match passenger demand, which has reduced the need for capacity-driven expansion at most airports. These reduced passenger levels, as well as the financial state of most airlines, put an additional financial burden on airport operators to maintain current rates and charges by making very sound capital investment decisions. Very often, components of terminal facilities reach the end of their useful life or become significantly outdated long before the structural integrity of the facility reaches the end of its useful life. However, these components, such as mechanical and IT systems, can be very difficult and costly to replace without major impacts to the facility and disruption to ongoing operations. Further compounding the issue is the lack of space at many airports to simply construct replacement facilities and avoid much of the complexity of renovating existing facilities without significantly disrupting passengers or ongoing operations. Airports with adequate space face tough scrutiny from the airlines to provide significant justification that new facilities are a more financially feasible solution than renewing the current facilities. Thorough analysis of the myriad relevant factors is required in order to decide whether to renew existing facilities or construct replacement facilities, particularly when the new facilities are not capacity-driven. This detailed analysis is typically not included at the Master Plan level but should occur before facility programming and schematic design services are commissioned. Nor can this analysis be conducted by simply comparing the initial capital cost of multiple options but rather must provide a total cost outcome perspective over a consistent investment horizon. The objective of the research is to establish a set of decision tools that can be used by airport operators, airlines, and consultants in evaluating options to renovate existing terminal facilities or replace them with new facilities.

TI - Moving Toward an Air Traffic Control Display Standard: Creating a Standardized Target Symbology for Terminal Situation Displays
PY - 2010/08//Technical Note
SP - 72p
AB - In this study, the authors applied human factors best practices to the design of an enhanced target symbol set for terminal displays. To design new symbols, the authors first identified types of information that would be most operationally useful. Four types of information were selected that would provide the greatest operational benefits and tactical support for the controllers. These included aircraft category (Small, Large, Heavy, and Super Heavy), aircraft heading, aircraft altitude, and aircraft conformance to its assigned route or altitude. To evaluate the effectiveness of the symbols, search, sorting, and selection tasks were used that measured symbol preference, reaction time, and symbol identification. The results indicated that the controllers used consistent heuristics for categorizing symbols into different size and conformance categories. For both the heading and category coding, the authors also found benefits in terms of both increased accuracy and decreased reaction times. No benefits were found for the altitude coding. By using meaningful symbols to convey relevant tactical information, such as aircraft category and heading, both visual search speed and target detection accuracy are increased. On the basis of these findings, the authors propose a set of symbols and provide recommendations for creating standardized symbology for terminal situation displays and other safety critical systems.

TI - U.S. Airline Transport Pilot International Flight Language Experiences, Report 4:
Non-Native English-Speaking Controllers Communicating With Native
English-Speaking Pilots
PY - 2010/08//Final Report
SP - 42p
AB - In 1998, the International Civil Aviation Organization (ICAO) took a heightened interest in the role of language in airline accidents. Member states agreed to take steps to ensure air traffic control (ATC) personnel and flight crews involved in flight operations in airspace where the use of the English language is required were proficient in conducting and comprehending radiotelephony communications in English. This report is a compilation of responses and comments by a group of U.S. pilots from American, Continental, Delta, and United Airlines of their difficulties in international operations. In this report, their responses to questions 39-45 are presented as a compiled narrative. The authors derived six major thrusts: (1) The English language proficiency of non-native English-speaking controllers may be inadequate for high workload conditions; (2) Pilots develop and use different strategies to improve ATC communications once they determine the controller’s language proficiency; (3) Pilots describe ATC communications between users of the same and different languages; (4) Language switching distracts pilots and limits understanding, adversely affects situational awareness, leaves them with feelings of uncertainty, and increases their workload; (5) Language barriers most affect situational awareness just prior to top-of-descent and during taxi; and (6) How pilots compensate for reductions in situational awareness. The authors offer 16 recommendations to improve communication practices ranging from developing standardized and secure English language testing for use by all ICAO member states, to realistic emergency and nonroutine scenarios and simulations demonstrating use of conversational English to enhance datalink for surveillance and communications.

It is believed that such a project could springboard the concept into reality without a significant research & development time lag. This project will include the design and construction of a snow melt pad in a small test area of concrete pavement at the Greater Binghamton Airport. This test area will incorporate radiant heat using geothermal technology. The test area will be located under and near one of the airport's jet bridges and will measure approximately 2,800 square feet.

TI - Defining and Measuring Aircraft Delay and Airport Capacity Thresholds
AB - Average aircraft delay is often cited as an indication of airport capacity or used as a measure of when to build new runways or other improvements. Airport planners and modelers may deem a certain number of minutes to be "acceptable delay" to help define capacity. Airline delays are reported to the Department of Transportation (DOT) every month by the major carriers and reported publicly as "on-time performance," comparing the airlines' ability to provide a certain level of customer service. The term "Delay" often refers to the amount of extra time experienced by an aircraft or flight. However, they are defined very differently and have different applications to airport planning. At the same time, very little guidance exists as to what amount of delay should be used for determining airport improvements (for many years, the NPIAS suggested four to six minutes of delay at large airports, but that statement is no longer included). Without strong guidelines on airport delays, the general public and airport decisionmakers can have difficulty understanding why just a few minutes of average delay warrant spending millions for capacity enhancements. For the Federal Aviation Administration (FAA), most flight delays are not reported until they reach at least 15 minutes. The National Plan of Integrated Airport Systems (NPIAS) reports airport delays from the FAA's Aviation System Performance Metric (ASPM) database, including taxi-in, taxi-out, and airborne delays. Evaluation of proposed airport development projects identified in individual Airport Master Plans or Environmental Impact Statements rely on evaluations of delay as an indicator of constraints on the airport system. Usually, delay is expressed as a function of Annual Average Delay (AAD) against Annual Service Volume (ASV). While the use of this annual metric works as an indicator of the efficiency of the airfield, it is sometimes too simplistic and may mask the causes of airfield inefficiencies. Many other metrics are available. However for planning and environmental specialists who are not expert in this area, there is no readily available source summarizing each of the metrics along with their strengths and weaknesses, and the appropriate uses. The objective of this research is to develop a guidebook that (1) describes various types of aircraft/flight delays and how the measures are calculated through a synthesis of the major delay metrics and (2) offers guidance about when each delay metric should be used and what specific measures can be used to evaluate airport improvements.

TI - Integrating Aviation and Passenger Rail Planning
AB - The Federal government is actively pursuing the expenditure of billions of dollars on intercity passenger rail (ICPR) projects. However, it is not clear that there is a solid set of standardized, agreed-on methodologies for public leaders to use when complicated questions are asked about the impacts of intercity passenger rail on issues such as airport capacity. There is a lack of agreed-on tools to use in documenting the interrelationship between these public modal investments. Most important, there is a lack of an informed public debate about the potential of the complementary investments in aviation and rail systems in the United States. In many parts of the world, rail and air investments are seen as complementary elements of a larger multimodal and intermodal public policy. For example, scarce airport operational 'slots' in Frankfurt are available for profit-making international flights because those slots are not being used for short connections. In the United Kingdom, advanced planning is now under way that would link approval of a third runway at Heathrow to new intercity passenger rail service to the north. The two processes--approval of new runway capacity and planning for the connecting rail--are seen as part of one larger public policy debate. The Northeast Governors are keenly aware that intercity passenger rail, particularly the extensive Northeast Corridor Network and its high-speed passenger rail service is part of a larger transportation system that needs modal balance. Efficient use of this multi-state network dramatically affects the overall viability of the highway, aviation, freight, and commuter rail transportation networks that serve the region and the nation. Therefore the CONEG Policy Research Center and transportation policymakers from the northeast states are exploring policy and program options in which rail investments are seen as part of larger coordinated strategies to get the optimal output out of both air capacity improvements and rail capacity improvements--a goal which the northeast states and the CONEG Center have been advocating and working toward for over two decades. However, planning processes are often "siloed". This research would determine how to (1) integrate planning methods to better facilitate and support an enlightened public debate about what the two modes can and cannot accomplish together and (2) determine the data and analytic processes necessary to understand the benefit of undertaking integrated rail/air projects. The objective of this research is to create publically available tools and methods that would support a new level of multimodal transportation analysis to take place.

TI - Assessing Aircraft Noise Conditions Affecting Student Learning
AB - Community concerns over the effects of noise on children's learning present potential barriers to airport expansion and can contribute to delays in capacity improvements. Considerable evidence demonstrates that chronic exposure to noise is associated with reading deficits in children. Recent research conducted for the European Union (EU) suggests that a 5dB-increase in noise exposure translates to a 2-month delay in reading scores. Furthermore, a pilot study for the Federal Interagency Committee on Aviation Noise (FICAN) found that low-performing students' test scores were more likely to improve after their schools were insulated against aircraft noise. An important remaining question is the level at which learning impacts occur. In FY07, the Federal Aviation Administration (FAA) awarded $56.5 million in grants to insulate public buildings--mostly schools--often based on a criterion of Day-Night Average Sound Level (DNL) 65 dB. There has been no research to date to identify whether this criterion is appropriate for identifying noise impacts on schools. The Environmental Working Group (EWG) Science and Metrics Standing Committee of the Joint Planning and Development Office (JPDO) has proposed metrics to the EWG Policy Standing Committee for consideration in their preparation of the EWG environmental targets. The Working Group has proposed that JPDO use as a metric the number of students exposed to noise levels that affect learning, but has also identified a need for further development of this metric. The objective of this research is to collect and summarize current research on the impacts of noise on learning and relate this information to aviation noise and airports.

TI - Incorporating Sustainability into Traditional Airport Projects
AB - There is increasing attention to and awareness of "green" and "sustainable" initiatives in design and construction, not only in commercial and residential properties, but in airport improvements as well. There is widespread belief that incorporating these initiatives into projects may have higher initial costs, but there is little knowledge as to what the benefits may be. In some cases, lack of understanding and perception of increased costs has inhibited the implementation of these concepts and technologies into traditional (i.e., those projects not planned and designed with sustainability in mind) airport projects. Airport decision makers need to have a better understanding of the social, economic, and environmental benefits of incorporating sustainable design concepts and technologies into projects. They also need a process to evaluate and determine achievable, sustainable design concepts and technology alternatives that can be incorporated into traditional projects. As such, research is needed to develop a process for evaluating sustainable design concepts and technology alternatives in the planning and design phases of airport project development. The objective of this research is to develop a guidebook that airports can use to assist them in evaluating sustainable design and technology alternatives during the planning and design phases of airport project development.

TI - Addressing Uncertainty about Future Airport Activity Levels in Airport Decision Making
AB - Forecasts of airport activity levels are essential to airport planning and financing decisions. In recent years, however, the ability of traditional forecast techniques to produce reliable estimates has been a growing concern. There are numerous examples of situations where unforeseen events and developments have had a significant effect on realization of airport development plans. Many parameters essential for preparation of air traffic forecasts (e.g., economic growth, fuel costs, and airline yields) have recently become more volatile. For example, the extreme fuel price rises experienced in 2008 led air carriers to cut air service. This price increase was followed by a sharp economic downturn which, in turn, put additional pressure on airline yields, traffic levels, and air carrier viability. In addition, concerns around shock events (e.g., terrorism or health pandemics) have magnified the degree of uncertainty involved in producing reliable air traffic forecasts. The effects of changing economic conditions on air cargo demand, airline mergers and bankruptcies, and airline decisions concerning routes and hubbing activities have also impacted the reliability of air traffic forecasts. The traditional approach to handling uncertainty has been to supplement base case forecasts with high- and low-case forecasts to account for a range of potential outcomes. This approach, however, provides only a cursory understanding of the risk profile and provides no detail on how unforeseen events and developments actually affect forecasts and resulting decisions. It is important to incorporate a comprehensive analysis of risks and opportunities into those airport management plans that rely on air traffic forecasts. In an operating environment subject to a great deal of uncertainty, airports need to generate and incorporate accurate measures of numerous factors (e.g., fuel prices, economic growth, and industry structure) in their long-term forecasts in support of physical and financial planning. An effective and systematic analysis framework will assist airport managers in meeting this requirement. The objective of this research is to develop a guidebook and an associated reproducible and transparent systems analysis methodology to help airport management make decisions in the face of uncertain futures, recognizing and addressing risks and opportunities as input to facility planning and development. This research will assess how various external factors (e.g., fuel price, user taxes, airline strategies, regulations, social and demographic change, technology change, environmental change, and changing market and financial conditions) affect airport activity levels as measured by number of origin, destination, and connecting passengers; number of aircraft operations; aircraft fleet mix; and air cargo volume. The guidebook and associated systems analysis methodology should (1) examine ways to identify and characterize risks and opportunities, including their plausibility and magnitude, and how to consider them as elements of comprehensive airport planning and development strategies; and (2) enable airport management to address risks and opportunities in their business models, so as to avoid surprise and need for belated action.

TI - Aircraft Taxi Noise Database for Airport Noise Modeling
AB - The Federal Aviation Administration's (FAA's) Integrated Noise Model (INM) is the agency's required tool for NEPA-related studies and FAR Part 150 studies. The transition of INM into the Aviation Environmental Design Tool (AEDT) is a prime example of the commitment of FAA to improving aviation environmental assessment computational capabilities. The AEDT program will achieve an important milestone in integrating FAA legacy tools and improving on their accuracy and functional capability to assess airport noise. For instance, improvements include changes in acoustic, emissions, and performance modeling capabilities, as well as improvements to noise-power-distance (NPD) curves, lateral attenuation algorithms, and relative-humidity absorption. ACRP recently contributed a key improvement to the noise modeling tools through Project 11-02/Task 8, "Enhanced Modeling of Aircraft Taxiway Noise." The objective of this scoping project was to determine the best way to model airport noise from aircraft taxi operations and to create a plan for implementing a taxi noise prediction capability into INM in the short term and AEDT in the longer term. One of the outcomes of the project revealed that the primary weakness for taxi noise modeling is related to a definition of engine source noise characteristics--level, spectra, and directivity. Currently, there is no direct noise database for taxiing operations--within the current INM/ AEDT models; source noise is obtained through an approximate extrapolation of NPD data. For long-term requirements it was suggested that additional measurements be made for taxi operations where synchronized noise and engine operating parameters can be obtained, so as to determine the noise sensitivity at low thrust settings and allow a realistic evaluation of breakaway thrust impact. This would require a considerable field measurement effort with extensive coordination with cooperating airlines. A short-term solution to the problem, suggested in the ACRP Project 11-02/Task 8 report, is to develop a noise, spectral class, and directivity database for a nominal taxi state by processing existing measurement data from a study conducted at Madrid Barajas International Airport. Although comprehensive, this measured dataset does not address all aircraft in common use at U.S. airports and needs to be supplemented with additional measurements for specific aircraft types. These measurements will record a sufficient number of taxi operations in order to develop statistically valid nominal taxi operating state source characteristics. The resulting database will remove the weakness in the current INM noise database and allow for much improved taxi noise estimates. The objective of this research is to use existing measured data, supplemented by a modest measurement program, to develop a comprehensive database of Noise/Spectral Class/Directivity characteristics for commercial aircraft operating at U.S. airports.

TI - Neuroimaging Study of Mental Fatigue
AB - The primary objective of technology development in this proposal is to develop neuroimaging technologies, based on modeling and computation, which are able to on distinguish activation brain networks and default mode brain networks in electroencephalography (EEG) data to identify different brain states. They propose to separate EEG data into components due to their temporal dynamic characterizations of statistical independence and due to their different spatial compartmentalization. The primary objective of scientific investigation in this proposal, with developed technologies, are to identify and monitoring brain states with EEG data; to quantify interference of mental fatigue on brain states due to the time-on-task effect; and to assess the recovery time after developing mental fatigues.

TI - The Role of Air Travel in the Transmission and Spread of Insect-borne Diseases
AB - Air travel has long been suspected to play a role in the transmission and spread of insect-borne diseases. Considerable resources have been devoted to addressing the phenomenon of "airport malaria" (isolated cases of malaria in the vicinity of an international airport in a region in which malaria is not typically present). The assumption is that airport malaria is transmitted when a mosquito is transported during an international flight from a malaria-endemic region and then bites a human after landing. This theory has given rise to the practice of "disinsection"--using chemical pesticides to rid arriving aircraft of insects prior to disembarkation--which currently is required as a condition of landing by 20 countries (though not by the United States). More commonly, malaria and other insect-borne diseases are imported by infected passengers. The existence of suitable habitat in non-endemic regions with competent insect vectors may lead to resurgence of not only malaria but also other devastating insect-borne diseases such as dengue and Chikungunya fever in non-tropical regions such as the U.S. The concern about the growing threat of insect-borne diseases, combined with the theory that air travel is allowing the importation (or reintroduction) of diseases in the U.S., has renewed interest in insect-control programs at airports and on aircraft. However, a more appropriate focus for controlling the introduction and spread of insect-borne disease would be the infected traveler. Research is needed to provide a better understanding of how the transmission and spread of insect-borne diseases are facilitated by air travel. Such research would provide a basis for airports, airlines, and public health officials to assess the appropriateness and efficacy of current mitigation practices. The objective of this research is to develop a user-friendly GIS-based tool on a CD-ROM to help better define the roles of airports and airlines in the transmission and spread of insect-borne human diseases. The tool should show the interrelationships among the global distribution of insect-borne infectious diseases, locations of known outbreaks, and international air service routes to identify seasonal risks of insect-borne infectious disease transmission and spread by air travel, and to help identify potential mitigation strategies.

AB - The Local Area Augmentation System (LAAS) is the United States implementation of internationally accepted standards for Ground Based Augmentation System (GBAS). GBAS augments the current Global Positioning System (GPS) service for terminal, non-precision, and Category I/II/III precision approaches in the National Airspace System (NAS). The Federal Aviation Administration (FAA) identified GBAS as an "Enabler" for the NextGen, Flexibility in the Terminal Environment Solution Set. The Houston GBAS initiative will support the early implementation of Global Navigation Satellite System (GNSS) technologies GBAS and Satellite-Based Augmentation System (SBAS), and at the same time support Houston initiatives for closely spaced parallel runway operations and wake separation research because of the GBAS linear capabilities and multiple glide path and offset touchdown capability.

TI - Alternative Fuels as a Means to Reduce PM2.5 Emissions at Airports
AB - More than sixty airports are located in non-attainment areas for PM2.5. As demand for air travel continues to grow, these airports will face increasing pressure to reduce their contribution to local emissions. Alternatives to petroleum-derived Jet Fuel A show promise in dramatically reducing the sulfur and aromatic content of jet fuel, therefore, resulting in a decrease in PM emissions from turbine-powered aircraft. Regions of the country where air quality exceeds the limits imposed by the National Ambient Air Quality Standards (NAAQS) are required to develop a plan to bring the affected areas back into attainment. This research aims to determine the degree to which introducing a low-sulfur and/or low-aromatic alternative to standard petroleum-derived Jet Fuel A at select airports within PM2.5 non-attainment areas can be an effective means of reducing PM emissions for the region. Many options (e.g., aircraft technology advancement, efficient operational procedures, use of alternative fuels, and others) are being investigated to limit airport/aircraft emissions. Evaluation of a combination of these options is necessary to address air quality-related environmental concerns effectively in the context of aviation growth forecasts. In particular, options considered should include alternatives to traditional Jet Fuel A, with special attention to use of ultra-low-sulfur jet fuel. As these options are explored, it is also important to understand and quantify changes in overall engine combustion emissions and their impact on the environment. This research will incorporate case studies at candidate airports to determine the extent to which alternatives to Jet Fuel A, including ultra-low-sulfur jet fuel, can reduce overall PM2.5 emission concentrations in a PM non-attainment area. The final report will include a framework for assessing lifecycle PM2.5 emissions that will be useful for future studies.

TI - Evaluating Alternatives For Aircraft Ground Power, Heating, and Air Conditioning
AB - Air quality (and specifically emissions) is an emerging issue that is beginning to affect airports and airlines. As such, airports are looking at alternatives for their own operations as well as for the airlines serving their airports. Aircraft auxiliary power units (APUs) are a source of emissions and noise; however, there are alternatives to APUs that provide ground power, heating, and air conditioning. These alternatives can be mobile units, terminal based, bridge based, or ramp based. Each of these alternatives has different capital and operating costs, as well as different effects on emissions. What works at one airport may not be applicable at another airport for various reasons such as different climate conditions, airline aircraft fleet, and terminal and ramp infrastructure. While airports are familiar with the range of alternatives to aircraft APUs, information is needed on their environmental benefits and other considerations (e.g., costs, funding, operational impacts, and maintenance) for selecting and implementing alternatives. Research is needed to provide such information to assist airports and airlines in evaluating APU alternatives. The objective of this research is to prepare a workbook for airport, airline, and environmental planners that can be used to evaluate alternatives to aircraft auxiliary power units (APUs) for power, heating, and air conditioning. The workbook should include tools to quantify the general emissions benefits of alternatives and to provide appropriate quantitative and/or qualitative analyses of the financial (e.g., capital, operating, and maintenance expenses) and operational implications, as well as any potential noise reductions that may occur. The workbook is intended to be a set of tools that will provide general emission information for various types of APUs, options, costs, and other considerations that can be applied.

TI - Airport-to-Airport Mutual Aid Programs
AB - Airports practice and understand working with their local community mutual aid organizations in responding to airport emergencies. However, when it comes to community-wide disasters (i.e., hurricanes, earthquakes) that adversely affect airport operations, airports may not be the first priority in the deployment of mutual aid assets. Airports are excellent resources for other airports during these disasters in that they have the exact type of asset and human resources with the knowledge to assist in the unique operating requirements of airport systems. Two grass-roots organizations have been created to provide these resources: the Southeastern Airports Disaster Operations Group (SEADOG) and the Western Airports Disaster Operations Group (WestDOG), known collectively as the DOGs. The DOGs serve as a mechanism to assist impacted airports and to coordinate with airports seeking to provide assistance, much in the same way as utility companies provide for each other. Airports are interested in participating in such groups, but with known financial, legal, and logistical hurdles, they have been hesitant to formally commit. With other industries having resolved or worked within these constraints, further research is needed to help airports develop and implement airport-to-airport mutual aid programs (MAPs). The objective of this research is to prepare a guidebook to help public airport operators of all sizes and types to develop and implement national and/or regional airport-to-airport mutual aid programs (MAPs) to plan, assess, respond, and recover from an event that adversely affects operations of the airport.

TI - Evaluation of MFAST for TARGETS
AB - Continuous Descent Arrival (CDA), also called Continuous Decent Approach, is a procedure where aircraft descend directly from a relatively high altitude without the traditional leveling off in a series of steps. Currently, CDA is implemented in conjunction with Area Navigation Standard Arrival Route (RNAV STAR) development and requires analysis and guidance for the development of the approach's vertical profile. The Federal Aviaton Administration (FAA) RNAV office has requested an additional module to its Terminal Area Route Generation Evaluation and Traffic Simulation (TARGETS) program, a requirement for RNAV procedure development. This additional module would be a procedure design tool for incorporating vertical profiles which include CDA criteria for altitude and speeds. The MITRE Corp. has proposed the development of an flight management simulation tool (MFAST) module to support the FAA RNAV office request. The FAA AEE would like to ensure that the module produces the desired criteria for the RNAV STAR vertical profiles. The goal of Project 39 was to evaluate MFAST by using output from its Tool for Analysis of Separation and Throughput.

AB - Recent increases in fuel prices have driven the commercial aviation industry to focus on fuel efficiency. The efficiency of propellers and prop-fans has produced renewed interest in advanced "open rotor" engine designs. To contribute to the design process, noise predictions need to accurately identify the issues associated with these new designs and must forecast the annoyance of the population near airports due to the new noise sources.

AB - This technical report provides a brief literature review of previous research on air traffic control concepts relevant to the Data Communications (Data Comm) program and examines the use of digital-taxi (D-Taxi) clearances for departure aircraft under three levels of data link equipage (Voice Only vs. 40% Data Comm vs. 75% Data Comm). Sixteen current controllers participated in a high-fidelity, human-in-the-loop simulation to assess the potential effects of D-Taxi on controller communications, workload, and performance. The authors collected measures of airport system efficiency and usability measures for the Tower Operations Digital Data System that enabled the D-Taxi functions and taxiway conformance monitoring. The authors examined the specific effects of taxi conformance monitoring and a complete data link system failure in an additional exploratory scenario. This report provides a detailed set of results and recommendations for future research and requirements generation that the Federal Aviation Administration should consider when implementing the Data Comm Segment 2 concepts.

TI - A Review of the Literature Related to Potential Heath Effects of Aircraft Noise
PY - 2010/07//Final Report
SP - 99p
AB - This literature survey emphasizes cardiovascular outcomes and the potential pathways from aircraft noise to health outcomes for possible cardiovascular endpoints. Two potential pathways are discussed: sleep disruption and noise-induced stress, because both have been related to possible cardiovascular outcomes. Researchers have shown nighttime aircraft noise to be more highly correlated to health impacts than twenty-four hour or daytime noise, and have found that observed effects in road noise studies have become stronger when house orientation and window opening habits at night have been taken into account. Research into health effects of industrial noise exposure as well as health effects associated with annoyance from community noise suggests that stress reactions, such as arousal of the cardiovascular system in response to a loud noise, may lead to negative cardiovascular outcomes as well. It has been proposed that repeated short-term increases of blood pressure and heart rate associated with these reactions may lead to changes in the functioning of the cardiovascular system and eventual hypertension. Thus, both sleep and stress, because they have been proposed as pathways leading from noise exposure to eventual cardiovascular outcomes, are of interest and have been focused on in this report. The last two chapters of this report include a discussion of unanswered questions and ideas and recommendations for future research that would: (1) help further elucidate the relationship between aircraft noise and health; and (2) provide decision makers with the tools that they need to optimize policy with regards to noise producing infrastructure in order to minimize negative health outcomes. Additionally, ways to conduct studies that might help address these unanswered questions and the feasibility of those approaches are also discussed.

PY - 2010/07//Final Report
SP - 70p
AB - Researchers at the Federal Aviation Administration William J. Hughes Technical Center Aviation Fuel and Engine Test Facility (AFETF) entered a Cooperative Research and Development Agreement (CRDA) with Swift Enterprises. Swift has plans to produce a high-octane, nonoxygenated, binary fuel from biomass for spark ignition, piston aircraft engines. Due to the binary nature of the fuel and the use of heavy aromatics, the Swift fuel will require engine and airframe testing to determine the performance effects of noncompliance with the current aviation gasoline specification properties regarding distillation slope. This research was performed on a Swift binary blend, manufactured in a refinery and not in bio-process, to determine whether there were any initial major engine performance-related findings that would prevent further research into the use of a Swift binary blend of these components. It is noted that trace materials found in this Swift binary blend may differ from those that arise from manufacturing of the components from a biomass fermentation process and will probably differ depending on sugar source and bio-enzymes selected. It is recommended that Swift perform additional engine, airframe, and fuel pump rig tests using a fuel made in their biomass process and perform the engine tests using a straight weight mineral oil.

AB - Traffic Collision Avoidance System (TCAS) behavior in New England airspace is being monitored and analyzed, making use of an omni-directional 1030/1090 MHz receiver. The receiver system, located in Lexington, MA, operated by M.I.T. Lincoln Laboratory, is used to record data for subsequent analysis in non-real time. One aspect of the program focuses on communication taking place during TCAS Resolution Advisories (RA's). Omni-directional receptions make it possible to examine the air-to-air messages exchanged between aircraft for coordination of RA's. Omni-directional reception rates are also being studied. The results indicate the percentage of aircraft that are TCAS equipped and the percentage of received signals that originate from TCAS and other systems. A third aspect of the program evaluates the availability of 1090 MHz Extended Squitter data for use in collision avoidance systems. Data is recorded continuously, and the busiest periods are selected for focused attention.

TI - Guidebook for Developing General Aviation Airport Business Plans
AB - Airports are not just transportation facilities; they are also a form of public and/or private business enterprise. The success, and indeed the survivability of this business enterprise, is in significant measure tied to its profitability. Profitable airports thrive; unprofitable airports often die a slow death. While considerable time and money is spent on systematic airport infrastructure planning and forecasting, many airports invest surprisingly little in systematic airport business planning. They are equally important. Airport business planning and airport master planning are essential and equal actors in planning the future of an airport. General Aviation (GA) airports are finding it more and more difficult to not only fund planned development but also to cover operational shortfalls. It is recognized that a good deal of effort and attention will be necessary to transform the airport into a revenue-producing facility. GA airports do not enjoy the economic support provided through passenger travel-related revenues and, as a result, many of these airports are not financially self-sufficient. The inherent difficulty of generating revenues from airport operations to meet both operational and capital needs is daunting, and getting more so. Investing in airport business planning is becoming essential to make airports self-sustaining. There is an immediate need at most airports to increase revenues, including potential non-aviation sources, and to scrutinize expenses for cost-savings. It is the intent of this research to document best practices for the preparation and implementation of business planning and their use as a primary fiscal tool in airport decision-making. A General Aviation Airport Business Planning Best Practices guidebook will be the result of this research project. Airport owners will be introduced to a business planning process that will enable them to objectively evaluate the business elements of the airport enterprise and then to take the necessary next steps to plan and act to achieve higher airport net revenues with an ultimate goal of reaching self-sufficiency.

TI - Winter Design Storm Factors for Airport Stormwater Management
AB - Winter storms are highly variable and present significant operational challenges for airlines and airport operators who must ensure compliance with both aircraft safety standards and environmental standards. As a result, the design of airport infrastructure to manage stormwater from aircraft deicing operations cannot be standardized from airport to airport. Development of stormwater management systems for "worst-case" deicing events could result in high cost for management of rare events. Alternatively, a stormwater management system that allows for frequent overflows could raise concerns about the ability to meet permit limits and/or water quality standards. A winter design storm is a single precipitation event or a sequence of precipitation events that a stormwater management system is designed to handle. There are various factors that are used in determining an airport's winter design storm, specifically, differences in the intensity of precipitation, the form of precipitation, the lag period between precipitation and run-off, and the need for and/or intensity of deicing activities. These factors result in large differences in the quantity and quality of run-off that requires management. The quantity and quality of run-off from aircraft deicing affects how airports are able to meet federal and state water quality standards. Determining the winter design storm is part of the process an airport must use in developing a stormwater management system to control aircraft deicing run-off, and airport operators need further guidance on how to define the relevant factors that should be considered in determining their winter design storm. The objective of this research is to develop a guidebook for airport designers and operators to define the relevant winter storm design factors and how they should be considered in determining a winter design storm for the purpose of sizing and selecting a collection, conveyance, storage, and treatment system in the management of run-off from aircraft deicing operations.

TI - Passenger Value of Time, Benefit-Cost Analysis, and Airport Capital Investment Decisions
AB - Airports invest billions of dollars in their airport infrastructure and provision of services yet they have relatively little specific knowledge of their customer's valuation of them. Similarly the Federal Aviation Administration (FAA) and Transportation Safety Administration (TSA) have limited knowledge and only rough approximations of the value that passengers, shippers, meeters and greeters, and the companies that pay for air travel place on efficient and cost-effective air transportation services. Airlines and other direct sellers of their travel services take a more direct pulse of the public's value for these services and have been unbundling some of these related services with their a la carte pricing schemes, but do not share their proprietary market valuations. The FAA uses a decade-old basis for valuing passenger time and DOT has not revised this value for use in the required cost-benefit analysis for capacity projects funded via the Airport Improvement Program (AIP). The Office of Management and Budget places major emphasis on the development of these cost-benefit studies and FAA has incorporated this requirement in the evaluation of their discretionary grants for capacity projects. Airports have relied on past planning practices or more subjective surveys of passenger satisfaction which do not yield information directly useful for rigorous investment evaluations. The estimation of capacity benefits relies principally on the service (value of time due to better and more reliable schedule and service patterns) and efficiency gains (reduced airline or operator costs), plus the informational value of understanding when the travel sequence will be accomplished, and in what steps. Airline operational and service practices have undergone major changes over the past two decades, but little research has focused on how these changes affect air passengers and their decisions. For example, passenger decisions and behavior may be influenced by current airline industry practices (e.g., hub and spoke versus direct service, reservation and booking practices, product differentiation strategies, and air alliance attributes; changes in the overall technology culture (e.g., internet and cell phone); or effects of security measures post 9/11. The purpose of this research is to provide a more current and comprehensive understanding of recent developments that would inform airports of their customers' valuations in order to make investment cases to airport managements, FAA and TSA, and the airlines or other airport users. An empirical or survey- based methodology for documenting these improved valuations will provide a basis for appropriate capital improvement plans and commitments that can pass scrutiny by FAA, GAO, and airlines and other users. Research is needed to account for how passengers value benefits associated with increased capacity and greater schedule certainty, frequency, timing, and other relevant characteristics that affect their decisions on traveling, including who, when, and what mode. This research may develop a database from a national survey of air passengers (similar to the ATA's Gallup surveys or major airport air passenger surveys) to estimate the passengers' values of time with the ability to differentiate between trip purpose, trip length, and other relevant passenger-trip and service characteristics (e.g., timing of flights, connection times, flight option redundancy, and flight frequency).

TI - Airport Ground Support Equipment (GSE) Inventory and Emission Reduction Strategies
AB - Increased levels of demand at airports in the United States have resulted in a growth in surface congestion and an associated increase in airport surface emissions. This problem is likely to worsen with the projected future increase in air transportation. Efforts are underway to decrease surface congestion. Local air quality and global climate change concerns, regulatory pressures, and the desire to be environmentally responsible have resulted in a growing number of airport programs around the United States to assess and reduce airport emissions. Although much is known about aircraft fleets, operations, and emissions, comparatively little is known about aircraft ground support equipment (GSE), a major part of airport ground operations and infrastructure and a manageable emissions source. What national GSE data are available are outdated and unreliable. Accurate GSE data are needed by the FAA and airport sponsors to plan adequately and to balance the growing air quality demands of the international community, States, regulatory agencies, and communities with the need for future airport system improvements. Although airport expansion plans to enhance system capacity in order to meet the increased demand may decrease delays and mitigate surface congestion, they will most likely exacerbate the problem of surface emissions. On the other hand, proactive strategies that limit surface emissions may help airports. This research intends to determine the locations and status of the most successful programs to limit or decrease emissions. Research will (1) identify operational approaches that have been implemented at various airports around the nation to reduce non-aircraft surface emissions and also implications of these approaches on LTO aircraft emissions; (2) examine the intended and realized benefits of these approaches within the context of present conditions and future aviation growth projections; and (3) develop strategies to address identified gaps or challenges. This project will also initiate a comprehensive and accurate GSE inventory to help the airport-industry assess the contribution of GSE to air quality impacts at airports. This information is critical to improved understanding and planning for future opportunities to convert conventionally fueled equipment (i.e., gasoline and diesel) to cleaner technology using alternative fuels. This information will be collected on an aggregated level to support national goal-setting, policymaking, and incentives-based low-emission programs, while protecting the proprietary interests of GSE owners and operators, including air carriers, FBOs, and ground handling companies. Note: Preparing an accurate and comprehensive inventory will require cooperation with third-party GSE owners and operators to undertake the labor-intensive process of identifying, categorizing, and inventorying GSE at airports across the country and putting into place a mechanism to ensure the accuracy of the data collected. Such voluntary support from GSE owners and operators may be difficult to obtain, given the current economic climate and limited resources available to devote to this volunteer effort.

TI - Information Security and Privacy Controls Over the Airmen Medical Support Systems
PY - 2010/06/18
SP - 31p
AB - This report presents the results of the U.S. Department of Transportation Office of Inspector General's (OIG's) review of the information security and privacy controls over the Federal Aviation Administration’s (FAA) Airmen Medical Support Systems (MSS). FAA requires airmen to hold a medical certification of their medical and mental fitness to operate aircraft. MSS currently stores more than 18 million medical records supporting the medical assessment of over three (3) million airmen. To ensure aviation safety and protect the privacy of airmen, it is critical that this medical information be secure. Also, coordination with other Federal agencies may improve aviation safety by identifying airmen who are receiving disability benefits and may not have disclosed potentially disqualifying medical conditions. This review was requested by the Chairmen of the House Committee on Transportation and Infrastructure and its Subcommittee on Aviation. The objectives of OIG's audit were to (1) determine if airmen’s personally identifiable information (PII) is properly secured from unauthorized use or access, and (2) assess FAA’s progress in establishing mechanisms to identify airmen holding current medical certificates while receiving disability pay. Briefly, the names, addresses, Social Security numbers, medical data, and other PII of airmen are not properly secured to prevent unauthorized access and use. OIG found serious security lapses in FAA’s management of AMEs private medical support staff access to the system. FAA has made limited progress in identifying airmen who receive disability benefits while holding medical certificates. While FAA has a draft matching agreement with the Social Security Administration (SSA) to reconcile data in MSS and SSA’s disability benefits system, it has yet to establish a target date for completing the interface. Further, FAA has yet to coordinate with other benefits providers, such as the Department of Veterans Affairs and the Department of Labor.

TI - Guidelines for Integrating Alternative Jet Fuel into the Airport Setting
AB - Virtually all of the fuel currently used in aviation operations is derived from petroleum. Petroleum fuel supply and associated pricing (both level and volatility) are key business challenges for the industry. In addition, concerns about environmental impacts compound challenges facing the aviation sector as it continues to meet demand. "Drop-in" alternative jet fuel (see Special Note A.) provides great promise for the aviation industry from an environmental, energy security, and economic perspective. Several demonstration flights during the past year have shown that technology is available to produce alternative jet fuel that can be used to safely fly existing aircraft. Key challenges to moving forward with commercial use of alternative jet fuel include formation of an effective business plan addressing production at marketable prices and quantities, deliverable at the appropriate point in the supply chain. One concept that has received significant industry interest is to locate an alternative fuel production facility on, adjacent to, or with access to an airport to take advantage of known demand. Access to a known demand at an airport could encourage investment by an alternative fuel producer in aviation fuel. In order to provide a path forward for siting an alternative fuel production facility, and associated infrastructure, research is needed to evaluate the legal, financial, environmental, and logistical considerations and opportunities associated with launching such a project. The objective of this research is to prepare a handbook for airport operators and others associated with "drop-in" jet fuel production and delivery that summarizes issues and opportunities associated with locating (on or off-airport) an alternative jet fuel production facility, and its storage and distribution requirements. The handbook will identify potential benefits; address legal, financial, environmental, and logistical considerations and opportunities; and aid in evaluating the feasibility of providing this capability.

TI - Asset and Infrastructure Management for Airports
AB - Asset and facility management is commonly used by organizations around the world to coordinate and oversee safe, secure, and environmentally sound operation and maintenance of these assets in a cost-effective manner aimed at long-term preservation of the asset value. Often, airports operate on a reactive maintenance philosophy where either (1) assets are run to failure, at which point they become a priority and are budgeted to be repaired; or (2) maintenance activities are underfunded, resulting in much more costly unplanned than planned maintenance events. The management of physical assets (their selection, maintenance, inspection, and renewal) can be key in determining the operational performance and profitability of those industries that operate assets as part of their core business. The objective of this research is to develop a guidebook for a proactive approach to airport asset management. The research will identify and define best management practices used by aviation and other industries to help formulate and develop asset management programs at various sized airports. The guidebook should encourage a proactive long-term way of thinking about facility development and ownership; focus on total cost of facility ownership, linking capital and operating costs; improve decision-making skills based on clear data and well-defined objectives; minimize economic waste; and combine environmental and financial performance.

TI - Timely Actions Needed To Advance the Next Generation Air Transportation System
PY - 2010/06/16
SP - 33p
AB - The National Airspace System handles almost 50,000 flights per day and more than 700 million passengers per year. Historically, steadily increasing levels of air traffic have resulted in increasing delays. While the current demand for air travel is down, it is expected to return, which will require better air traffic management to reduce congestion and decrease delays. To meet this anticipated demand, the Federal Aviation Administration (FAA) is developing the Next Generation Air Transportation System (NextGen) to replace the current ground-based air traffic control system with a satellite-based system. FAA’s goal for NextGen—to create a system that will handle up to three times more air traffic and reduce FAA operating costs—is ambitious and involves multibillion-dollar investments from both the Government and the airline industry. Since the effort began in 2005, the U.S. Department of Transportation Office of Inspector General (OIG) has repeatedly reported on the cost and schedule risks and operational and management challenges NextGen faces. These concerns prompted OIG to identify NextGen as one of the Department’s top management challenges. The Chairmen and Ranking Members of the House Committee on Transportation and Infrastructure and Subcommittee on Aviation requested that OIG examine FAA’s progress in transitioning to NextGen. This report provides the results of OIG's review. Specifically, it addresses (1) key actions needed to successfully implement NextGen, (2) FAA and partner agencies’ progress in leveraging resources and budgets, and (3) FAA’s efforts to engage the private sector in shaping NextGen policy issues. In addition, OIG was asked to report on FAA’s progress in implementing OIG's past NextGen-related recommendations. Briefly, a number of critical actions are still needed to move NextGen from planning to implementation. FAA has yet to establish firm requirements to help guide cost and schedule estimates for adjustments to existing projects or new acquisitions. FAA also faces challenges in developing an integrated budget to help ensure it leverages the right resources, pursues realistic goals, and secures adequate funding for projects. While FAA has made some progress in engaging the private sector to develop NextGen and shape NextGen policy issues, several challenges remain. For example, FAA is working with a Government/industry task force to gain consensus on NextGen operational improvements that can be achieved in the midterm (2012 to 2018), but significant policy issues remain unresolved.

TI - Guidebook for Selecting Methods to Monitor Airport and Aircraft Deicing Materials
AB - The management of deicer runoff at airports is an industry-wide concern. Effective management requires the ability to obtain on-site measurements of various parameters such as Total Organic Carbon (TOC), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), ammonia (NH3), pH, Dissolved Oxygen (DO), water temperature, and glycols (propylene, ethylene). In addition, measurements need to be taken at multiple locations, at differing frequencies, and across a wide range of deicer concentrations. These measurements are needed for internal runoff management as well as to meet regulatory requirements. Accurate and reliable on-site measurements also have the potential to reduce operating and infrastructure costs. Although a wide range of on-site monitoring options are available, and more are being developed, there is a relatively high degree of uncertainty regarding the potential performance of individual instruments and methods. This uncertainty makes it difficult for airports to make informed decisions regarding the selection of the most appropriate monitoring techniques to meet operational and compliance requirements. Pending environmental regulations make this issue both timely and important. Accordingly, research is needed to review and evaluate on-site monitoring options to assist in the decision-making process. The objective of this research is to prepare a guidebook to enable airports to identify, compare, and select practical on-site methods (i.e., instruments, technologies, techniques, etc.) for monitoring deicing materials in water.

TI - Operational and Business Continuity Planning for Prolonged Airport Disruptions
AB - As an integral part of the national and global infrastructure, airports have a major impact on the economic viability of not only the jurisdiction and region in which they are located, but that of all the markets they serve. In addition, hub airport closures can hamper and degrade service in all markets served by the carriers that use the facility. Airports are experts at emergency response as required by FAR 139. Most incidents experienced by airports last less than one operational period/day. However, if an airport were to experience a catastrophic event that would last several days or weeks, the impact on the local, regional, and national economy would be great. In a prolonged recovery, several weeks to possibly months, alternate business processes, work locations, alternate passenger handling facilities, and other business and operational considerations would be necessary. Given that most models of business continuity plans are based on an information technology format, it has been difficult for airport operators to translate the key roles, critical processes, and other elements to the airport environment. Elements such as alternate facility locations, remote access to critical business functions, and succession planning are among the issues that require in-depth, critical consideration. Research is needed to build a guide for airports that will allow them to consistently and effectively plan for recovery from a prolonged disaster. This guidebook would be the logical next step for airports in a comprehensive emergency and recovery plan. The objective of this project is to develop a guidebook that airport officials can use to effectively prepare and plan for the sustained ability to operate during and after a catastrophic event.

NoiseQuest provides an outreach forum for airports too small to have an established community program as well as information that supports existing outreach efforts. NoiseQuest was designed to educate and inform the public, and to provide an independent source of information that can help to contribute to improved airport-community relationships. NoiseQuest is "layered" so that information is available to people with differing interest levels. This allows users to access the amount of information they wish, so that some users are not overwhelmed by a page of text, and others are not disappointed that the information is sparse. NoiseQuest addresses the concerns of citizens in an easy to understand format.

TI - NextGen En Route Traffic Optimization to Reduce Fuel Burn and Emissions Part 2
AB - En route airspace throughput (the number of aircraft than can safely fly though a given location over a given time) can be increased by optimizing aircraft cruise altitude and speed based on the distance between their origin and destination. The increase in throughput, and the corresponding reductions in fuel burn and emissions, result when aircraft can fly closer to the optimum altitude for their performance characteristics, and from a reduction in situations where one aircraft gets "stuck" behind another with a lower optimal cruise speed.

TI - Risk Analyses to Enhance GBAS Performance for NextGen Applications
AB - The objective of the project is to address two open questions which are central to the development of CAT III Ground Based Augmentation System (GBAS). The first of these questions is whether or not existing CAT I integrity monitors, such as the Excessive Acceleration and Signal Deformation Monitors, can be adapted for use with a CAT III system, given that CAT III integrity risk requirements are stricter by two orders of magnitude. To make such adaptation possible, the research will mitigate excess conservatism that exists in prior integrity analyses, specifically, in assumptions made regarding time-correlated random noise and its impact on monitor missed-detection probabilities. The research will also address a second key open question for CAT III GBAS implementation: how to make effective use of modernized, multi-constellation Global Navigation Satellite System (GNSS) signal in GBAS.

TI - Synthesis of Information Related to Airport Problems. Topic S10-06. Investigating Safety Impacts of Energy Technologies on Airports and Aviation
AB - As the federal government increases its support for alternative energy sources such as solar panel arrays, wind turbines, and power plants, the impact of these technologies on the operational safety of airports is coming under renewed scrutiny. Solar energy is one of the more affordable and adaptable alternative energy technologies. Despite its accepted use adjacent to airports, there are numerous misconceptions that continue to preclude its development at many GA airports. There are two potential safety concerns frequently expressed regarding solar panels. The first is glare reflecting off of the panels, the second is the proper placement of the panels. Solar panel placement practice at GA airports to avoid airfield hazards, to avoid land use compatibility conflicts, and to facilitate future airport expansion is needed. There is literature on the impacts of wind turbine height published in Federal Aviation Administration Regulation Part 77. Synthesizing existing information on the extent of radar interference occurrences between wind turbine farms and various types of air traffic control radar systems would help dispel concerns and promote interagency planning collaboration. States and local governments are seeing an increase in the number of applications to locate power plants adjacent to airports. Exhaust plumes have the potential to create in-flight hazards that affect the control and maneuverability of aircraft. However, the literature that supports efficient siting of newer technology plants near airports is not available in one location in a concise format for use by airport operators, aviation land use planners, and regulators. The objective of the synthesis project is compile existing research literature and current practice on how these developing energy technologies can and do coexist with safe operations at airports. The intended audience for the report is airport operators, planning managers, and regulators responsible for considering aviation safety while facilitating alternative energy production and developing energy technologies. The synthesis report would serve as a useful tool for those involved in locating power plants generating thermal plumes, wind turbines, or solar arrays in the vicinity of airports. The report would compile the effects of solar, wind turbine, and power plant siting on airports, and assemble reviewed literature and undertake survey or case study of appropriate, Federal and state aviation agencies and other relevant organizations in order to identify common practices. Of particular interest is practice related to reflective glare from solar panels, electromagnetic interference and turbine height, and exhaust plumes from power plants, which all have the potential to interfere with a pilot's operation of an aircraft, including general aviation aircraft.

TI - Application of Enterprise Risk Management at Airports
AB - Enterprise Risk Management (ERM) is the process by which threats to and opportunities for an organization are identified, evaluated, and integrated across all disciplines in order to determine how to exploit opportunities, and mitigate, transfer, or avoid threats. Airports are conducting risk management activities, but they often aren't being coordinated on an enterprise level so that information gleaned through the process can be used in the strategic planning process, the decision-making process, and the allocation of limited resources. Other industries have implemented ERM and realized many benefits. From these experiences there are many lessons learned that can be applied at airports. ERM is not a one-time process that produces a report for the CEO or the executive management team, but rather a paradigm shift in the entire operation of an airport. Research is needed to help airport CEOs understand ERM, how it can be applied, and how to put it into practice. The objectives of this research are to develop (1) a guidebook for airport CEOs and their executive team on the application of enterprise risk management (ERM) to airports and (2) an electronic tool that can be used to prepare a risk classifications matrix. The guidebook should (a) define ERM; (b) examine the benefits, costs, and risks of implementation; (c) describe the process to implement ERM; (d) describe how the ERM process integrates with an organizational strategic planning process; and (e) describe how the information gathered through the ERM process can be used in airport organization's decision-making process. The guidebook should include forms and worksheets that can be used to implement ERM at airports.

TI - Developing and Maintaining Support for New Airport Capacity
AB - Successful delivery of new airport capacity projects (including new runways and runway extensions, airspace improvements, terminal expansion, and ground access improvements) can take many years. Such projects are most likely to succeed with steady support from airport sponsors, political constituencies, airport users, interest groups, regulatory agencies, and nearby communities. Not only is it critical for project proponents to identify, mobilize, maintain, and broaden support, they also need to deal constructively with project opposition. These efforts should start early and occur at every critical stage (i.e., conception, planning, design, regulatory approval, and financing) to the point at which project development is assured. Research is needed to examine some of the many past and ongoing airport capacity projects to identify useful lessons on developing and maintaining project support and to provide guidance for airports based on these lessons. The objective of this research is to prepare a guidebook for airports that provides strategies for developing and maintaining stakeholder support when undertaking new airport capacity initiatives. The guidebook should contain specific suggestions and checklists that can be used by airports to develop and maintain such stakeholder support.

TI - Synthesis of Information Related to Airport Problems. Topic S06-02. Airport Self-Inspection Procedures and Training Practices
AB - Self-inspection to promote airfield safety is a primary responsibility of the airport operator. Typically, self-inspections are conducted by airport employees to detect existing and potential hazards. Self-inspection is considered a critical component of airport operations, are regularly scheduled, and include the following: daily airfield inspection; continuous surveillance of certain airport activities (e.g., fueling, construction, maintenance); periodic evaluation for surveying obstructions, approach slopes and other facilities and activities not requiring daily inspection; and special inspection resulting from weather, complaints, wildlife activity, or construction activities. FAR Pt 139.303 requires personnel with access to the movement and safety areas be trained to perform duties in compliance with the requirements of the Airport Certification Manual. FAR Pt 139, Section 327 stipulates self-inspection, including timing and requirement to keep self-inspection records. Staff training to inspect, use checklists generated by the airport operations executives, report results and remedy deficiencies varies widely among airports. There are tools available to conduct training of self-inspection procedures for purchase/hire, and some airports have developed tools in-house. The objective of this synthesis project is to collect and document common self-inspection conditions reporting training practices across North America for the range from large carrier airport to general aviation airport. The target audience is airport operations managers and staff. The synthesis report will provide airport operators with the range of self-inspection conditions reporting training operation, including low tech to high tech, hired/purchased versus in-house. Note that the National Academies does not endorse products. The research will highlight common practices in training and will document the range of reasons that different airports choose the options that each has implemented.

SP - 34p
AB - This study is based on 1036 accidents (of which 672 were survivable) that occurred between 1968 and 2007 involving large transport category turbojet and turboprop western-built aircraft operating in a passenger or passenger/cargo role. Over the study period, there was a marked reduction in the total accident rate both for the world fleet and the combined U.S. and Canadian fleets. This reduction is apparent when the accident rate is measured on a per flight, per passenger, or per revenue passenger mile basis. The survivability of accidents has also shown a marked improvement over the study period with a greater proportion of accidents being survivable and a marked increase in the proportion of occupants surviving an accident. These improvements are apparent in both the world fleet and the combined U.S. and Canadian fleets. It would seem that fatalities attributable to impact represent a larger proportion of the total number of fatalities in survivable accidents than those that are caused by fire.

TI - Distribution of Oxycodone in Postmortem Fluids and Tissues
PY - 2010/06//Final Report
SP - 12p
AB - Introduction: Oxycodone is a heavily used and abused analgesic agent. Its pharmacological effects, including euphoria, respiratory depression, nausea, and drowsiness, have the potential to adversely affect performance. The postmortem distribution of oxycodone has not been well characterized, particularly at sub-lethal levels. Therefore, an attempt was made to evaluate the distribution of oxycodone in postmortem specimens collected from aviation accidents. Methods: A search of our database identified 4 oxycodone-positive fatalities from separate civil aviation accidents that occurred during a period of 6 years that had numerous biological tissues and fluids available (blood, urine, vitreous humor, liver, kidney, skeletal muscle, lung, spleen, heart muscle, and brain). These specimens were extracted using solid-phase extraction and were analyzed for oxycodone by GC/MS. Results: Oxycodone concentration ranges (μg/mL, μg/g) found in the different tissues and fluids were: blood 0.027-0.742, urine 2.20 - 12.5, vitreous humor 0.048 - 0.118, liver 0.103-3.35, lung 0.047-1.35, kidney 0.045- 3.12, spleen 0.115-2.43, muscle 0.017-0.400, brain 0.032-1.36, and heart 0.038-3.19. Conclusion: The blood concentrations found indicate that the oxycodone in these cases ranged from therapeutic to above therapeutic, but all were below lethal levels. Tissue/fluid to blood distribution coefficients were found to have large coefficients of variation (ranging from 26-128%), thereby rendering them unreliable for estimating a blood oxycodone concentration from a tissue value when no blood is available for analysis.

TI - Project 27 - Ultra Low Sulfur
AB - Aircraft emissions can reduce air quality, leading to adverse health impacts including increased risk of premature mortality. A technically viable way to mitigate the health impacts of aviation is the use of desulfurized jet fuel, as has been done with road transportation in many jurisdictions. To attain levels of 15 ppm from the current average levels of 400-800 ppm would increase the cost of jet fuel by 1.6-6.6 ¢/gal, i.e. an increase in the cost of a gallon of just over 1% at 2011 prices. Although the environmental implications are complex, research indicates transitioning to an ultra-low sulfur jet fuel is likely to prevent 1000-4000 premature mortalities per year (if implemented globally), but may increase globally averaged climate warming caused by aviation by 1-8%. Commercial aviation fuel (Jet A/A-1) contains sulfur at concentrations of 400-800 ppm, although there is significant variation. By contrast, US road transportation fuel is subject to an ultra-low sulfur fuel standard of 15 ppm, which is about 97% less than jet fuel. Other jurisdictions including Australia, Canada, New Zealand, Mexico, Japan, India, Argentina, Brazil, Chile, Peru and the European Union have instituted similar standards for road transportation. Marine fuels are being subjected to increasingly stringent standards too, but marine bunker fuels have higher sulfur content than aviation or road transportation fuels. Sulfur in fuel results in the emission of SOx (sulfur oxides) upon combustion. SOx is predominantly a gas when emitted, but gets converted in the atmosphere to a form of fine particulate matter (i.e. small particles) called sulfate. Sulfate particles predominantly scatter solar radiation, some of it back into space, therefore offsetting a fraction of global warming, although whether this is climatically beneficial or not is a subject of continuing research. A second important effect of SOx emissions is to increase the amount of fine particles that people inhale. There has been substantial quantitative evidence collected over decades that links human exposure to fine particulate matter to an increased risk of premature mortality and other adverse health effects. Finally, SOx emissions result in acid rain and associated damages. Jet fuel can be desulfurized in the same way as road transportation fuels. Jet fuel is chemically very similar to diesel and there are no significant technical challenges in doing this, although a corrosion inhibitor/lubricity improver (CI/LI) may need to be added to the resultant fuel in order to prevent excessive component wear within engine fuel pumps. This is done routinely in the military and the cost is negligible compared to the cost of desulfurization. This hydrodesulfurization process will increase the cost of fuel by just over 1% at present-day prices, which maps to an industry total $1.3-3.8bn per year (in 2006 US$) if implemented globally, or $0.5-1.4bn per year for the US alone. The dominant adverse environmental result of desulfurization is that removing sulfur from fuel results in increased CO₂ emissions because hydrodesulfurization involves the release of relatively small amounts of CO₂ and consumes additional energy. A second potentially adverse effect is that the reflection of solar radiation into space by sulfate particles would be reduced. In combination, these are estimated to increase the globally-averaged climate warming caused by the production and use of a gallon of jet fuel by 1-8% if it is desulfurized. Using benefit-cost analysis techniques, the monetized climate damage due to global implementation of ultra-low sulfur jet fuel (ULSJ) is $0.1-4.3bn per year, which is a net present value with an applied 3% discount rate. The discount rate defines the charged interest rate on a value stream, be it a cost or benefit, in one year compared to the following year. This means that the higher the discount rate, the less future costs or benefits are valued relative to the base year. The magnitude of the discount rate defines the annual percentage reduction in value a cost or benefit undergoes as compared to the previous year. Of these damages, $0.01-0.7bn is incurred in the US. If only the US implements ULSJ, the damages in the US are $0.00-0.2bn per year. ULSJ would prevent 1000-4000 premature mortalities per year globally due to a modeled reduction in ground-level fine particulate matter, of which about 5% are in the US. When US-only implementation is considered, ULSJ causes a reduction of about 80 premature mortalities per year in the United States (US). While a reduction in premature mortalities is relatively confidently predicted, the monetization of these mortalities depends on the approach. The United States Environmental Protection Agency (US EPA) recommends the use of a single (but uncertain) value of statistical life for analyses within the US. If this approach is applied to all avoided premature mortalities globally, ULSJ results in $1.2-47bn of health benefits each year globally. In the US, global implementation of ULSJ results in $0.06-2.4bn of benefits per year. If only the US implements ULSJ, the air quality benefits in the US are $0.04-1.5bn per year. Applying the US EPA value of statistical life globally means that there is an 84% chance that ULSJ is net beneficial, i.e. the public health benefits exceed the additional fuel production costs and climate damages. However, economists argue that there is no economic rationale for applying a single value of statistical life because incomes vary greatly around the world and so willingness to pay for reductions in mortality risk varies. If country-specific values of statistical life are used - which are derived considering country-specific income levels and are uncertain as well - then there is an 83% chance that ULSJ is not cost-beneficial on net. This is because the majority of mortality reduction occurs in developing countries where monetized health benefits outside the US are decreased due to lower income levels. An important point is that in all these cases the uncertainties are such that the net difference between the benefits and costs of ULSJ does not statistically differ from zero. However, the most likely scenario is that ULSJ would save thousands of lives if implemented globally, increase aviation-related globally averaged climate warming by 1-8%, and increase fuel costs by at least 1%. An argument for transitioning to an ultra-low sulfur jet fuel is that the health benefits are highly likely and the industry could work to offset the additional 1-8% of increased warming by reducing greenhouse gas emissions."

TI - Assessing and Implementing Innovative Revenue Strategies--A Guide for Airports
AB - As the domestic and world economies continue to exert stress on the economic health of the aviation industry, airports seek to reduce expenditures as well as diversify and improve their revenue streams. These efforts are apparent by the growing practice to solidify current sources of revenue while looking to improve future financial conditions in situations where financial forecasts are difficult; i.e., many airports are developing new and innovative revenue-generating techniques to supplement more traditional methods. Research is needed to collect information about and analyze the effectiveness of existing and new and innovative techniques for generating revenue for airports. Research is also needed to analyze untried ideas for capturing a reasonable percentage of the value created by airport passenger and cargo activity in order to help an airport's economic condition. The research proposed in this study would evaluate a wide range of revenue-generating tools and techniques now in practice as well as develop innovative techniques, perhaps not yet in practice. Based on the ability to measure an airport's long-term contribution to regional economic value, the study would identify alternative techniques that could capture a portion of that value as a new revenue source for airport planning, operation, expansion, environmental considerations, and overall development.

TI - Sonic Boom Metrics
AB - As demand for long range business travel increases and technologies for efficient supersonic flight mature, a market for small supersonic civil aircraft appears to be forming. However, a major remaining impediment to the operation of such aircraft is the cruise noise signature. Sonic boom noise issues are different from many other aspects of aircraft noise in that the potential annoyance occurs en route, along the flight path rather than just near airports. Maximum utility will require supersonic flight over land, currently prohibited by law. Recent research on shaped sonic booms has indicated low boom designs are possible and result in significantly less objectionable signatures than classic booms of the 1960s - 1980s. Supersonic aircraft operation and sonic boom signatures were investigated for low boom designs, as the overarching goal of Project 8.

TI - Synthesis of Information Related to Airport Problems. Topic S10-5. Ground Handling Training and Practices
AB - Traditionally, airport operators have trained personnel on ramp security and movement area safety regulations and practices. Over the past few years, airports and airlines have been asked to develop comprehensive safety and operational training programs for ramp activities, adding non-movement areas and aircraft safety envelopes and assorted ground handling equipment to the traditional airfield traffic lanes training. Many of these training programs have been developed in absence of industry standard or an assessment of effective or common practices. In fact, the Government Accountability Office has found in the Reauthorization Issues Paper that "At least 29 fatal ramp accidents have occurred since 2001. However, efforts to improve airport ramp safety are hindered by a lack of complete accident data and standards for ground handling. FAA has generally taken an indirect role in overseeing ramp safety, and there are no federal or industry-wide standards for ramp operations. Varied standards for ramp operations could lead to confusion about operating procedures and safety rules among ground handling companies that provide service to several airlines and increase the likelihood of accidents." Research is needed to collect these practices, examine the rationale for the practice and what factors influence the practice. The objective of this synthesis project is to provide airport operators and users with a summary of ground handling practices and training tool resources. The audience for this synthesis would be airport and aviation safety and training professionals. The synthesis report will provide case studies of airports, airlines and ground services operators that engage in training and have established practices. The research will highlight common elements of successful programs and training tools. The research for this project will include literature review and interview of up to ten ground handling operations organizations. Common elements of identified programs and effective practices will be identified and reported.

TI - Synthesis of Information Related to Airport Problems. Topic S03-06. Adaptive Re-use of Vacated on Airport Facilities
AB - Over the last decade, the air transport industry's financial condition has deteriorated significantly. Several air carriers and service organizations have either failed or have been forced to file for bankruptcy. During this period, a number of factors have contributed to the dramatic financial losses for airlines, particularly legacy carriers, including rapid cost escalation for fuel, employee benefits, retiree obligations, September 11 terrorism, and losses of profitable passenger and cargo component traffic. In response, air carriers and service providers have reduced their operating costs, restructured their operations, and adopted new business strategies to counter unsustainable financial losses and to achieve long-term financial viability. A core part of some business' recovery strategies have been to invalidate no-longer-needed long term facility leases with airports. Many carriers now contract for services in lower cost locations or that use non-union employees. For example, the majority of major aircraft scheduled maintenance is now undertaken through contracts with non-union maintenance centers in Asia. Airport revenues and budgets are negatively impacted when an airline or service provider vacates a long-term leased facility. When an airport tenant vacates a facility, particularly under bankruptcy protection, the airport becomes immediately responsible for closing the facility, remediating hazardous conditions left by the tenant, and implementing a reuse strategy. All of these tasks are unbudgeted expenses, and many times, difficult to implement.

AB - Birds strikes make-up 97% of the reported aircraft strikes. In the recent past, there have been many more aircraft incidents/accidents stemming from bird strikes on and off airport property. Airports are often located next to wildlife attractants such as waste management and transfer facilities, water management facilities, wetlands, agriculture, shorelines and other habitats that provide shelter, nesting area and feeding area for birds. Additionally, successful bird management and repellant techniques are location, ecosystem and species specific. The large number of bird strikes has resulted in a major effort by United States and Canadian airports officials to find ways to manage wildlife attractants in the airport environs and repel bird strike hazards.

TI - Synthesis of Information Related to Airport Problems. Topic S04-06. Current Airport Inspection Practices Regarding FOD/Wildlife Hazards
AB - Self-inspection to promote airfield safety is a primary responsibility of the airport operator. Recent events have focused increased attention on airports' responsibilities to mitigate FOD and wildlife hazards. Airports conduct airfield and mandatory runway inspections, in part to monitor for and mitigate such hazards. In addition, upon notification from air traffic control or findings from self-inspection, airports respond and remove FOD and/or animal carcasses from operational surfaces. There is wide variation in how airport operators incorporate FOD and wildlife hazard inspection into airport management. Additionally, there is no readily available compendium of current airfield and runway monitoring and inspection practices at U.S. airports from which airport operators can review and improve their own inspection practices. FAA is sufficiently concerned to have recently issued an advisory circular governing the purchase of FOD detection systems with AIP funding. They have also issued a CERTALERT emphasizing the need for timely FOD removal, and expect to issue a FOD management advisory soon. This project will synthesize current literature and FOD and wildlife hazard inspection practices across airports to develop a comprehensive compendium of current practices in this area. The report will describe the range of inspection practices, from low-tech to fully automated and high-tech, and reasons for why the practice is chosen by an airport operator, including all benefits in addition to cost. The objective of this synthesis project is to compile FOD and wildlife management inspection practices across a wide variety of North American airports. The target audience for this synthesis is airport operators responsible for FOD, wildlife hazard, and other airfield and runway safety inspections.

AB - From 1991 to 2000, the Federal Aviation Administration (FAA) conducted vertical and longitudinal and static and dynamic tests of various narrow-body transport airplane fuselage sections, which included different types of in-service overhead stowage bins. Vertical drop impact tests were conducted at the FAA William J. Hughes Technical Center, Atlantic City International Airport, New Jersey. Longitudinal, simulated impact sled tests were conducted at the Transportation Research Center, East Liberty, Ohio. This report summarizes the distribution of loads among the bin support members for both static and dynamic loading conditions, the strengths, and failure modes (if any) of various overhead stowage bins. This information will provide a basis to assess the adequacy of the design standards and regulatory requirements for overhead stowage bins.

TI - Evaluation of Retro-Reflective Beads to Increase Airport Surface Marking Conspicuity
PY - 2010/05//Technical Note
SP - 102p
AB - Manufacturers have postulated that retro-reflective beads that have a higher index of refraction increase the conspicuity of paint markings and, thus, would aid in the prevention of runway incursions. The purpose of this project was to determine the adequacy of various types of retro-reflective beads that are used to increase the conspicuity of painted markings when applied to airport surface markings. The increased conspicuity could assist in the prevention of runway incursions. Five types of retro-reflective beads were evaluated: three are currently approved by the Federal Aviation Administration (FAA) for use on airfield markings, as indicated in FAA Advisory Circular 150/5370-10D and two are the newly proposed retro-reflective beads. The beads were applied to standard paint on three types of airport pavement surfaces: hot-mix asphalt (HMA), Portland cement concrete (PCC), and aged HMA. Three test sites were chosen. Test Site One was located inside the FAA William J. Hughes Technical Center National Airport Pavement Test Facility on new HMA. Test Site Two was located at the FAA William J. Hughes Technical Center Aircraft Parking Apron on aged PCC surface. Test Site Three was on Taxiway Bravo at the Atlantic City International Airport, which is comprised of aged HMA. This evaluation covered a 1-year period starting in August 2008. This research validates previous research performed on Type I, Type III, and Type IV retro-reflective beads. No previous research was performed on the two newly proposed retro-reflective beads. The initial application tests concerning coverage, water, and pull-off strength were deemed successful. On new HMA, the test marking with Type IV retro-reflective beads remained conspicuous for the longest period of time. Type I, Type III, and Manufacturer B retro-reflective beads remained conspicuous for approximately half that time, and Manufacturer A for approximately one-quarter of the time. All the approved retro-reflective beads proved suitable for use on aged HMA and aged PCC over a 1-year period. The proposed retro-reflective beads from Manufacturer A and Manufacturer B also proved suitable for use on aged HMA and aged PCC.

TI - Full-Scale Tests on Rubblized Pavement Test Items at the National Airport Pavement Test Facility
PY - 2010/05//Technical Note
SP - 42p
AB - Rubblization is defined as the process of fracturing existing concrete pavement in-place into smaller interconnected pieces. Rubblization breaks the slab action and minimizes or prevents the occurrence of reflective cracks in the asphalt concrete overlay. This is the first study conducted on the full-scale accelerated pavement testing of rubblized concrete pavements with hot-mix asphalt overlay under heavy aircraft loading. Full-scale traffic tests were completed on three rubblized and nonrubblized rigid airport pavements overlaid with 5 inches of hot-mix asphalt at the Federal Aviation Administration National Airport Pavement Test Facility. Initially, the overlaid pavements were trafficked with a four-wheel landing gear (with wander) and a 55,000-lb wheel load. No significant distresses were observed during the first 5000 passes. The wheel load was then increased to 65,000 lb and a six-wheel landing gear was used. Test item MRC (rubblized concrete pavement on conventional base) exhibited complete structural failure. Test item MRG (rubblized concrete on grade) was suffering severe structural deterioration at the end of trafficking but retained sufficient structural capacity to support the applied load. Test item MRS (rubblized concrete over econocrete base) did not exhibit severe structural deterioration at the end of trafficking. Four trenches were excavated perpendicular to the centerline of the test items to conduct posttraffic investigation into the failure mechanism of the pavement structure. The trenching included tests for layer characterization (plate load tests, California Bearing Ratio tests, in situ densities, moisture contents, layer profile measurements, and visual evaluations) and removal of each of the pavement layers to reveal the subgrade interface and subsequent subgrade layers below. This report summarizes the results from pavement layer characterization tests, pavement structure uniformity from heavy-weight deflectometer tests, pavement performance during the traffic tests, changes in the modulus of the rubblized concrete layer with deterioration in pavement structure backcalculated using BAKFAA. The report also summarizes the results from the posttraffic tests and provides some insight into the failure mechanism of rubblized concrete airport pavements.

TI - Toxicological Findings in 889 Fatally Injured Obese Pilots Involved in Aviation Accidents
PY - 2010/05//Final Report
SP - 18p
AB - Obesity continues to be a public health concern and its impact on aviation community has not been fully evaluated. Toxicological findings in fatally injured aviation accident obese pilots were examined. The Civil Aerospace Medical Institute's (CAMI's) Scientific Information System was used to develop a dataset, entailing fatally injured obese pilots involved in aviation accidents, 1990–2005. A pilot with a body mass index (BMI) of > 30 kg·m•2 was considered obese. Toxicological results and aeromedical histories of these aviators were retrieved from the CAMI toxicology and medical certification databases, and the cause/factors in the related accidents were retrieved from the National Transportation Safety Board's aviation accident database. In 311 of the 889 pilots, carbon monoxide, cyanide, ethanol, and drugs were found, and glucose and hemoglobin A1c (HbA1c) were elevated. Many of these drugs were for treating overweight, depression, hypertension, and cardiac conditions. In a pilot (BMI: 39.33 kg·m•2) wherein phentermine was detected, vitreous and urinary glucose concentrations were 301 and 6,050 mg 11.5 dL•1, respectively; HbA1c was 12.4%. Of the 889 pilots, 107 had an obesity-related medical history. The health and/or medical condition(s) of, and/or the use of ethanol and/or drugs by, pilots were the cause/factors in 55 (18%) of the 311 accidents. Although the drugs found are commonly used in the general population, they were primarily used for treating obesity-related medical conditions. Findings emphasize monitoring of obesity and diabetes in pilots and understanding the potential implications of these health conditions in relation to flight safety.

TI - U.S. Airline Transport Pilot International Flight Language Experiences, Report
3: Language Experiences in Non-Native English-Speaking Airspace/Airports
PY - 2010/05//Final Report
SP - 44p
AB - In 1998, the International Civil Aviation Organization (ICAO) took a heightened interest in the role of language in airline accidents. Its Air Navigation Commission was directed to complete the task of strengthening relevant ICAO provisions concerning language requirements. Member states agreed to take steps to ensure air traffic control (ATC) personnel and flight crews involved in flight operations in airspace where the use of the English language is required were proficient in conducting and comprehending radiotelephony communications in English. Since then, ICAO developed its English- Language Proficiency requirements (ELP) and urged its members to document their ELP test implementation plans by March 8, 2008. Until all ATC personnel and flight crews involved in flight operations obtain a passing level of ELP, the language-based problems international pilots face is not known. This report is a compilation of written responses and comments by a group of 48 U.S. pilots of their difficulties in international operations who met with interviewers to discuss their language experiences flying into countries where English may or may not be the local or national language among its radio operators, controllers, and pilots. In this report, the pilots’ responses to questions 31-38 and their comments from discussions of those questions with interviewers are presented as a compiled narrative. The pilots’ responses had nine major thrusts: (1) Traveling into non-native English-speaking countries can be a positive learning experience leading to professional growth and development; (2) English-language proficiency varies from country to country and individual to individual; however, problems occur everywhere; (3) Hearing multiple languages on the radio restricts situational awareness and diminishes pilots’ expectations as information derived from the party line decreases; (4) Radio protocol is lost in a multilingual environment; (5) Whenever communication problems occur, flight deck operations slow down as the flight crew diverts attention away from other tasks, so more of their attention is directed to listening to what the controller said; (6) Communicating with non-native English-speaking controllers requires more effort and concentration to ensure the intent of the controller’s transmission is understood; (7) When off-normal events arise, controllers have difficulty communicating in Common English, and pilots have difficulty understanding them; (8) Voice characteristics contribute to intelligibility and the ease with which pilots and controllers understand each other; and (9) Advanced avionics such as TCAS/CDTI, FMS, and CPDLC/DataCom offer possible solutions to the language barrier.

TI - Guidelines for Airport Sound Insulation Programs
AB - To assist sponsor-approved noise programs, FAA published AC 150/5100-9A in July 1993 that announced the availability of the Guidelines for the Sound Insulation of Residences Exposed to Aircraft Operations (the Guidelines). The Guidelines themselves were published in 1992 for military and FAA airports programs to serve as a project management handbook for studying, initiating, and implementing sound insulation measures developed under airport noise compatibility programs. The Guidelines were updated in 2005 by the U.S. Navy for application at military airports. The Navy updated the guidelines to meet their current program objectives and to reflect current building codes and insulation product specifications. Research is needed to develop updated guidance for sponsors to effectively manage noise insulation programs of eligible structures in conformance with FAA Noise Compatibility Program (NCP) and Airport Improvement Program (AIP) funding requirements. The objective of this research is to develop updated guidelines for sound insulation of residential and other noise sensitive buildings for potential use by airport and non-airport sponsors to develop and effectively manage their aircraft noise insulation projects. Noise sensitive buildings are defined as "residences (single family and multi-family), schools, hospitals, churches, and other non-compatible structures identified in the sponsor's NCP and approved by the FAA as a project in the NCP," as defined in AIP Handbook FAA Order 5100.38C paragraph 812.A.

TI - Synthesis of Information Related to Airport Problems. Topic S01-03. Airport Insurance Coverage and Risk Management Practices
AB - With airport operators responsible for a wide range of activities, and the potential for litigation to arise from a variety of events occurring on and off the airport premises, airports typically purchase insurance coverage to mitigate against risk of loss, as well as self-insure or obtain specific deductibles/retentions for certain risks. Since the 9/11 terrorism attack, and in the aftermath of various hurricanes and other natural disasters, significant challenges have been posed to airport authorities with regards to their property and casualty insurance needs. Airports in some locations have experienced challenges in obtaining insurance coverage. While some airport authorities have a risk manager and established practices to determine their needs for each of these coverages, others do not. In those cases, the airport authority must rely solely on the recommendations of a hired risk management consultant or insurance broker, or to simply continue to renew insurance coverage annually without any additional analysis. The objective of this project is to synthesize current practices airport operators use in deciding insurance requirements and risk management activities.. The audience for this report is airport executives and risk managers. A synthesis of practices will review literature and survey a representative sample of airports to report on airport insurance coverages. The report will document current practices and identify the key factors for airports to consider when making decisions on their own insurance requirement needs and risk management practices.

TI - Synthesis of Information Related to Airport Problems. Topic S01-04. Airline and Airport-Airline Consortiums to Manage Terminals and Equipment
AB - Airports and airlines continue to work together to find new strategies for delivering services to passengers and maintaining operations at airports in a cost-effective manner while providing quality service to passengers or users. While frequently facilities and services at airports are managed under the control of the airport operator or individual airlines, at some airports certain services or operations are conducted through consortiums of airlines, or airlines and the airport operator. The objective of the project is to synthesize current literature and survey results from consortiums existing at airports who: (a) provide services to passengers or groups of airlines or other airport users or (b) maintain facilities at an airport. The survey will serve as an initial resource for airport operators and airlines considering the use of consortiums at their airport. The target audience for this report is airport executives responsible for airline and tenant agreements who may be interested in advocating for and supporting consortiums to provide airport services. The synthesis investigator will review literature and survey a representative sample of airport operator and consortium principals to describe the current state of the practice.

TI - Next Generation Aircraft Debris Hazard Area Calculator Requirements Definition and Prototyping
AB - The Contractor shall identify and document requirements for the next generation aircraft debris hazard area calculator. These requirements shall be based upon requirements for the Shuttle Hazard Area to Aircraft Calculator (SHAAC), developed and enhanced under multiple task orders of this contract, and the lessons learned in its design, development, testing, and operations. These requirements shall address the input, output, interface, and computational algorithm needs of a tool to support airspace management around space operations through the prediction of aircraft debris hazard areas associated with the reentries of capsule-type vehicles, such as the SpaceX Dragon and the Orbital Sciences Cygnus, and controlled reentries of other space objects, including satellites. These requirements shall address the following: (a.) The input of predicted vehicle state vector data in a format specified by the Federal Aviation Administration (FAA). (b.) The input of debris characteristics specific to the reentry vehicles being analyzed. (c.) The output of input predicted state vector data, formatted for input into existing air traffic tools such as the Display System Replacement (DSR) and NOTAM system (format templates to be provided by the FAA). (d.) The output of computed predicted debris hazard area packages, consisting of both graphical and textual representations of the computed areas, for manual entry into existing air traffic tools (format templates to be provided by the FAA). (e.) Output of additional parameters, including ---- Input trajectory and computed hazard areas in KML format ---- Fall time of debris, by class, from breakup to various altitudes, such as 60,000 ft, 18,000 ft, and surface, output in time since breakup and GMT based on both predicted and realtime input vehicle state vector data ---- Length, width, and orientation of each computed hazard area based on input predicted vehicle state vector data ---- GMT of the vehicle's entry and exit of each predicted hazard area based on input predicted vehicle state vector data ---- GMT of the beginning and end GMT at which an underlying Air Route Traffic Control Center is at risk of falling debris based on input predicted vehicle state vector data ---- Graphical representation of portions of the predicted trajectory and hazard areas that correspond geographically to input predicted times of loss of signal and acquisition of signal (f.) An interface to a realtime stream of vehicle state vector data, delivered via virtual private network (VPN) or other Internet protocol. (g.) The automated entry of state vector data received via the realtime stream into the computation of a best estimate debris hazard area. (h.) The automated graphical representation of vehicle geographical position based on input realtime state vector data. (i.) The logging of all realtime data received. (j.) The playback of logged realtime data (k.) Potential algorithm improvements needed to address failure modes associated with capsule-type vehicles and the controlled reentries of other space objects, including: ---- Realtime hazard area computation during periods of loss of signal ---- Predicted hazard area computation based on trajectory guidance and performance uncertainties, including those uncertainties associated with the performance of the deorbit burn. Prototyping of these requirements, through pseudo-code or beta-software, shall be conducted, where applicable and possible. The requirements identified shall be documented, along with their corresponding rationale, in a report suitable for distribution to AST and its Air Traffic Organization partners.

TI - Review of Screening, Placement, and Initial Training of Newly Hired Air Traffic Controllers
PY - 2010/04/01
SP - 21p
AB - This report provides the results of The U.S. Department of Transportation Office of Inspector General's (OIG's) audit of the Federal Aviation Administration’s (FAA’s) policies and procedures for screening, placing, and initially training newly hired air traffic controllers. Over the next decade, FAA plans to hire and train nearly 15,000 new controllers to replace those who were hired after the 1981 strike and are now retiring. With this large influx of new hires planned, examining and improving its processes for integrating new controllers into the current workforce will be a significant challenge for FAA. OIG's audit objectives were to (1) evaluate how FAA determines whether candidates have the requisite abilities to become successful controllers, (2) determine what procedures FAA uses to place controllers at air traffic facilities, and (3) assess whether the initial training provided by the FAA Academy adequately prepares new controllers for facility on-the-job training (OJT). Briefly, FAA’s process for selecting and placing new controllers does not sufficiently evaluate candidates’ aptitudes before placing them at facilities. Currently, FAA does not use results of its controller aptitude test (the Air Traffic Selection and Training test, or AT-SAT) to determine the level of facility in which new controllers are placed. Instead, FAA assigns new controllers to locations based primarily on their facility choice and available vacancies. As a result, new controller candidates are being assigned to some of the busiest air traffic control facilities in the Nation with little consideration of whether they have the knowledge, skills, and abilities necessary to become certified controllers at those locations. These include critical facilities within the National Airspace System, such as the Southern California Terminal Radar Approach Control and the Chicago O’Hare and Atlanta Hartsfield Air Traffic Control Towers. FAA also does not use candidates’ initial performance at the Academy to determine the level of facility in which new controllers are placed. Although all controller candidates must attend 2 to 3 months of initial training at the Academy after passing AT-SAT, controller candidates are assigned to a facility before entering Academy training. Initial training at the FAA Academy is currently focused more on short-term memorization rather than developing a long-term skill set and, according to facility managers, does not adequately prepare candidates to begin facility training at their assigned locations. Facility managers OIG spoke with stated that candidates arrive after passing Academy training unprepared to begin facility training, often requiring additional time and resources to refresh them on subjects previously taught at the Academy. FAA internal studies have noted similar concerns. In an internal analysis conducted in November 2007, FAA found that Academy training needed to focus more on basic air traffic control concepts—such as phraseology, issuing clearances, and aircraft characteristics—and less on retaining knowledge just long enough to pass a test. The study recommended numerous changes to initial training, but more than 2 years since its completion, changes have not been implemented. OIG is making recommendations to FAA on actions needed to improve its controller screening, placement, and initial training programs.

TI - Airborne Evaluation of Retro-Reflective Beads
PY - 2010/04//Technical Note
SP - 56p
AB - This project was undertaken by the Federal Aviation Administration (FAA) Airport Safety Technology Research and Development Sub-Team as part of an effort to determine the relative conspicuity, from an aircraft on approach, of Type I and Type III retro-reflective beads. Retro-reflective beads are designed to redirect and return light back to its source. The inclusion of retro-reflective beads in painted surface markings can increase their conspicuity. It has been suggested that Type III retro-reflective beads, which have a higher index of refraction (IOR) compared to Type I beads, will substantially increase the conspicuity of paint markings and could help prevent runway incursions. The FAA uses Federal Specification TT-B-1325D, “Beads (Glass Spheres) Retro-Reflective,” to specify retro-reflective beads. Previous studies by the United States Air Force and the FAA have shown that in cases where the light source is not in close proximity to the observer’s line of sight, the benefit of using higher IOR beads is negligible. Since 1994, all research on retro-reflective beads has been focused on surface markings from the ground to improve the conspicuity of taxiway hold position markings, which aid in the prevention of runway incursions. Due to advances in bead technology, it has been suggested that additional tests be conducted from the pilot’s perspective on approach to a runway. Type I and Type III retro-reflective beads were installed on the same type of airport pavement markings at opposite ends of Runway 13/31 at Atlantic City International Airport (ACY) for a period of 8 months and side by side on Runway 10 at Savannah/Hilton Head International Airport (SAV) for a period of 2 months. Subjective data was collected in the form of questionnaires completed by test subjects from aircraft approaching the runway at both locations. The test subjects were queried concerning ease of marking detection and conspicuity. Objective measurements were taken at the beginning and the end of the evaluation. The majority of the test subjects involved in the tests at both ACY and SAV stated they do not use runway markings as a visual cue on approach to a runway at night. They focus on the runway lights. Of the subjects participating, all but one reported no difference in ease of detection between Type I and Type III bead markings. The chromaticity and retro-reflectivity characteristics of the bead markings were acceptable following initial application and throughout the evaluation period. While the Type III beads had a greater retro-reflectivity reading after initial installation, the effects on conspicuity from a pilot’s perspective on approach to the runway were minimal. Also, the higher retro-reflectivity readings of the Type III beads only lasted a few months at ACY then leveled out to the same retro-reflectivity values as the Type I beads for the remainder of the markings’ useful life. This study revalidates the airborne research performed in 1994 and is consistent with other ground-based research performed to date including research completed in 2009.

TI - Development of an Improved Fire Test Method and Criteria for Aircraft Electrical Wiring.
PY - 2010/04//Final Report
SP - 95p
AB - The Federal Aviation Administration (FAA), as part of its hidden in-flight fire mitigation program, developed an improved flammability test method for aircraft electrical wiring insulation materials (including jackets and other wire protective materials). A comprehensive fire test research and development (R&D) project was conducted on aircraft electrical wiring insulation materials in an effort to continue mitigating the threat of in-flight fires. Previous work at the FAA and the National Fire Protection Association have indicated that the current FAA-required 60-degree Bunsen burner test for electric wire was inadequate to qualify wire when bundled and subjected to a severe ignition source. A literature search and in-house fire tests were conducted during this effort. The results of the literature search indicated that there was no small-scale flammability test standard available that considered radiant heat and wire bundling in its specifications or acceptance criteria that included burn length and after-flame extinguishing time; therefore, an improved flammability test standard for aircraft wiring was required. In-house fire tests were conducted to develop an improved flammability test and provide support data; tests included the current FAA-required 60-degree Bunsen burner test, the microscale combustion calorimetry test (ASTM D 7309-07), the thermogravimetric analysis (ASTM E 2550-07), the intermediate-scale fire test, and the radiant heat panel test. From this R&D effort, an alternative radiant heat panel test method was developed. This method was effective in evaluating the in-flight fire resistance qualities of aircraft electrical wiring insulation.

TI - General Unknown Screening by Ion Trap LC/MS/MS
PY - 2010/04//Final Report
SP - 22p
AB - During the investigation of aviation accidents, postmortem specimens from accident victims are submitted to the Federal Aviation Administration’s Civil Aerospace Medical Institute (CAMI) for toxicological analysis. The first, and perhaps most important, step in the analysis process is the initial screening of biological specimens for illicit, medically prescribed, and over-the-counter compounds that may be present and could have been the cause of the accident. Currently, our General Unknown Screening (GUS) procedure involves both gas chromatography/mass spectrometry (GC/MS), liquid chromatography/diode array detection (LC/DAD) and fluorescence detection techniques. Both techniques have inherent limitations that prevent the detection of certain types of compounds. LC/DAD, however, is more limited due to poor sensitivity and specificity. Therefore, our laboratory developed and validated an LC/MS/MS procedure that provides far superior sensitivity and specificity to that of LC/DAD. The combination of GC/MS with LC/MS/MS will allow for the detection of more compounds at lower concentrations than our current techniques.

TI - United States Airline Transport Pilot International Flight Language Experiences Report 2: Word Meaning and Pronunciation
PY - 2010/04//Final Report
SP - 48p
AB - In 1998, the International Civil Aviation Organization (ICAO) took a heightened interest in the role of language in airline accidents. Its Air Navigation Commission was directed to strengthen relevant ICAO provisions concerning language requirements. Member states agreed to take steps to ensure air traffic control (ATC) personnel and flight crews involved in flight operations in airspace where the use of the English language is required were proficient in conducting and comprehending radiotelephony communications in English. Since then, ICAO developed its English Language Proficiency (ELP) requirements and urged its members to document their ELP test implementation plans by March 8, 2008. Until all ATC personnel and flight crews involved in flight operations obtain a passing level of ELP, the language-based problems international pilots face is not known. This report is a compilation of written responses and comments by a small focus group of 48 U.S. pilots of their difficulties in international operations. The focus group consisted of 12 international U.S. pilots each from American, Continental, Delta, and United Airlines. Each focus group met with two interviewers to discuss their language experiences flying into countries where English may or may not be the local or national language among its radio operators, controllers, and pilots. In this report, the pilots’ responses to questions 24-30 and their comments from discussions of those questions with interviewers are presented as a compiled narrative. The pilots’ responses had eight major thrusts: (1) Once pilots get past the controller’s accented English, understanding is not a problem during routine operations; (2) the lack of standardized pronunciation of NAVAIDs, waypoints, intersections, etc. complicates understanding what was said; (3) Currency in flight time in the theater of operation is critical to understanding accented English and will influence how easily controllers from different countries are understood; (4) Poor radios and transmission quality contribute to the unintelligibility of some controller transmissions; (5) Variations in pronunciation can detract from flying, as pilots must listen intently to clearances; (6) Training is essential for crews lacking currency going into a foreign country; (7) Differences associated with U.S. and ICAO phraseology need to be resolved and procedural ambiguities eliminated; and (8) Technological advancements such as controller pilot datalink communications (CPDLC) and automatic dependent surveillance (ADS) can mitigate some of the problems associated with accented English. The authors offer 10 recommendations to improve communication practices, which include development of a standardized phraseology, its presentation, delivery technique, and meaning, training, and implementation of ICAO’s ELP by all member states.

AB - The NextGen Concept of Operations and an Enterprise Architecture have been developed to establish a framework for the future based on today's best information. These documents define two major concepts upon which NextGen will develop Four Dimensional Trajectory Based Operations (TBO) and Air Traffic Management. The four dimensionals measure spatial coordinates, altitude and time. A set of systems would collect and disseminate 4D data to provide complete situational awareness to pilots, controllers and air traffic managers. The goal is allow flights to find their best route, rather than restrict them to controlled paths. Currently the Federal Aviation Administration (FAA) controls air traffic in the National Airspace System (NAS) using defined flight paths and airspace restrictions that do not take full advantage of the capabilities of an aircraft or its systems. NextGen will transition FAA to a more collaborative environment where pilots and FAA managers work together to tailor an aircraft's route for optimum safety and efficiency.

PY - 2010/03/10/Final Report
SP - 33p
AB - The advent of suborbital transport brings promise of point-to-point (PTP) long distance transportation as a revolutionary mode of air transportation. In 2008, the International Space University (ISU) of Strasbourg, France, published a report documenting its appraisal of PTP transportation technology. This report describes the conditions that should be put in place to foster and sustain the growth of this industry from the technical, market, financial, infrastructure, safety, and legal perspectives. The ISU study calculates that transatlantic flight times for suborbital vehicles from London to New York would take less than 1¼ hours, less than one-third the travel time required by the supersonic aircraft Concorde and a fraction of that required by conventional commercial aircraft. This potential for the rapid global transport of passengers and the fast distribution of goods and services make PTP transportation an attractive space technology concept worth exploiting. Based on ISU findings, the Federal Aviation Administration (FAA) Office of the Associate Administrator for Commercial Space Transportation (AST) recognized a need to identify issues and approaches for integrating PTP systems into the National Airspace (NAS) and International Air Space (IAS). The goal of this study is to provide FAA AST with technical support in formulating effective policies and regulations that address issues associated with the air traffic management (ATM) of commercially-operated, suborbital PTP transportation focused on the long distance delivery of both humans and cargo. The Volpe Center examined the issues associated with integrating PTP Systems into the NAS and international airspace by:

TI - Future En Route Workstation Study (FEWS III): Human-in-the-Loop Simulation of Air Traffic Controller Management of Advanced Aircraft Concepts
PY - 2010/03//Technical Report
SP - 123p
AB - The Federal Aviation Administration (FAA) and the Joint Planning and Development Office have developed the Next Generation Air Transportation System (NextGen) in an effort to transform the existing air traffic system to manage anticipated increases of up to three times current traffic levels by 2025 (FAA, 2008b). In this third volume of the Future En Route Workstation Study (FEWS) series, the authors conducted a simulation with eleven en route air traffic controllers to provide an initial evaluation of three NextGen-related concepts: the increased use of Area Navigation (RNAV) routes, aircraft self-spacing (one aircraft follows a lead), and aircraft grouping (two or more aircraft fly as in military formation flight). The simulation was conducted under very high traffic conditions (two to three times current levels) using a Baseline system that simulated the En Route Automation Modernization (ERAM) system and using the FEWS system that added features and capabilities to support controller tasks. The authors found many benefits for the FEWS system. The participants managed more aircraft, held traffic less, and reported lower workload and higher performance when they used the FEWS system. The authors also found benefits for the use of RNAVs that implemented both lateral and vertical conformance constraints. The participants managed more aircraft and issued fewer voice clearances to aircraft. The authors found few objective benefits of self-spacing and grouping. The participants commented favorably on self-spacing, but they commented negatively on grouping.

TI - Symbols for Cockpit Displays of Traffic Information
PY - 2010/03
SP - 78p
AB - A web-based study assessed pilots ability to learn and remember traffic symbols that may be shown on a Cockpit Display of Traffic Information (CDTI). These displays convey data obtained from Automatic Dependent Surveillance-Broadcast (ADS B) and related Aircraft Surveillance Applications System (ASAS) technologies, as well as other surveillance data sources. Three aspects of using the traffic symbols were evaluated: intuitiveness, ease of learning, and ease of remembering the symbols. Four symbol sets were tested, each with approximately 22 symbols. Each participant saw only one of the four symbol sets. The sets used different visual features of the traffic symbol to represent the Directionality, Data Quality, Air/Ground State, Alert Level, Selection State, and Pairing State of nearby aircraft. A total of 623 pilots with a broad range of experience participated. Results showed that while some conventions are well understood, such as the use of red and yellow for warnings and cautions (respectively), other conventions may be confusing and should be avoided. Results of the study were considered by a Federal Advisory Committee that develops standards for these traffic displays (RTCA Special Committee 186).

TI - Effects of Video Weather Training Products, Web-Based Preflight Weather Briefing, and Local Versus Non-Local Pilots on General Aviation Pilot Weather Knowledge and Flight Behavior, Phase 2
PY - 2010/03//Final Report
SP - 30p
AB - This research had two main phases. Phase 1 investigated three major questions, one of which was whether or not video weather training products could significantly affect general aviation (GA) pilot weather knowledge and flight behavior in marginal meteorological conditions. Fifty GA pilots took a general weather knowledge pre-test, followed by exposure to either one of two weather training videos (the Experimental groups) or to a video having nothing to do with weather (the Control group). They next took a post-test to measure knowledge gain induced by the training product. Finally, they planned for and flew a simulated flight mission through marginal weather from Amarillo, TX, to Albuquerque, NM. Multivariate modeling implied that a combination of higher pilot age, receiving either weather training product, and takeoff hesitancy could significantly, correctly predict 86.7% of diversions from deteriorating weather and 77.8% of full flight completions. The question then became whether or not this model would be robust over time. In the present study (Phase 2), after a time lapse of 3-4 months, 44 of the 50 original Phase 1 pilots returned for further testing. Again, they were tested for weather knowledge and flew a simulated flight mission similar to Phase 1’s. No significant change in weather knowledge was evident from Phase 1 to 2, nor were any significant differences seen between the three treatment groups. Additionally, the 3-factor model of Phase 1 failed to significantly predict flight diversions or flight completions in Phase 2. The combined results of Phases 1 and 2 imply that the effects on weather knowledge and flight behavior of a single 90-minute training video seem minimal in comparison to the complexities of weather itself and flight into weather. This is consistent with intuition. Moreover, what small effects are produced seem to decay with time. None of this is unexpected. It merely means that weather is complex, and effective weather training must be intensive to begin with and ongoing to remain effective.

TI - Evaluation of the Effects of Hydrogen Peroxide on Common Aircraft Electrical Materials
PY - 2010/03//Final Report
SP - 22p
AB - Aircraft can be contaminated with unwanted chemical or biological elements. For years, hydrogen peroxide has been used to disinfect equipment in the medical community. The diluted vapor form of hydrogen peroxide is being considered for use as a decontaminant/disinfectant/sanitizer of transportation vehicles aircraft, buses, subway trains, ambulances, etc. Previous work showed that STERIS Corporation’s Vaporized Hydrogen Peroxide (VHP®) technology could be used successfully in complex transportation vehicles. However, the compatibility of the process with typical aircraft avionics has not been established. This report documents a preliminary evaluation of the effects of hydrogen peroxide exposure on avionics (i.e., avionics wires, active circuit boards, and dummy circuit boards).

TI - Trajectory Management - Arrivals (RNAV/RNP w/ 3D and Required Time Arrival)
AB - This project will ensure that the safe and efficient transition of aircraft from en route to terminal airspace with appropriate sequencing and spacing. Several key mechanisms will be necessary to support this more efficient transition. Required Navigation Area Navigation/Required Navigation Performance (RNAV/RNP) procedures with vertical constraints and required time of arrival will provide the precision necessary to avoid using extra separation between aircraft. Use of metering times at key merge points will be used by air traffic managers as used today in Center-TRACON Automation System Traffic Management Advisory (CTAS TMA). In this type of operation, an aircraft's meter point time (MPT) is used to determine when it enters into the TRACON airspace and is given clearance to continue to the assigned runway. Metering must take into account runway load balancing and will serve to reduce (but not eliminate) the need for delay absorption needed inside the TRACON.

TI - Quick Response for Special Needs. Task 18. Primer on Carbon Credits and Revenue Opportunities for Airports
AB - The growing concern for the impact of CO2 emissions on the environment has led to policies and regulations designed to control and limit greenhouse gas (GHG) emissions. One outcome of these regulations has been the development of carbon markets, where carbon credits are bought, sold, and traded. As airports evaluate their options in the new market and regulatory environment, there may be potential for them to generate revenue by generating and selling credits in the carbon market. However, as the carbon credit market continues to evolve, there are many questions regarding airport participation, including the kind of credits airports can create or trade, who can take credit for various actions at an airport, the minimum level of credits needed to be marketable, and how carbon trading would affect airport compliance obligations, including grant assurances made to the federal government. Research is needed to provide the airport community with current, relevant information on the carbon trading market and potential opportunities and/or challenges to their participation in this market. The objective of this research is to prepare a primer for airports that describes the carbon credit market and outlines potential opportunities for and challenges to airport participation.

TI - Quick Response for Special Needs. Task 17. Risk Assessment of Proposed ARFF Standards
AB - Federal legislators are considering issues that could eventually lead to a change in aircraft rescue and firefighting (ARFF) requirements at airports. To date discussion has centered on "voluntary consensus standards" promulgated by the National Fire Protection Association (NFPA), although there are International Civil Aviation Organization (ICAO) standards as well. The practical effects of a change to the federal requirements could include (1) an increase in ARFF staffing, (2) a reduction in ARFF response times, (3) increases in the airport area that must be served within the response time, and (4) increases in ARFF equipment. Airport operators, ARFF professionals, and federal regulators need a fuller understanding of each of these potential effects, as well as the potential safety effects of the proposed changes. ACRP's Web-Only Document 7: How Proposed ARFF Standards Would Impact Airports (http://onlinepubs.trb.org/onlinepubs/acrp/acrp_webdoc_007.pdf.) describes current NFPA and ICAO standards for ARFF at airports. This research, led by GRA, Incorporated, examined the cost implications if airports adopted these standards. To assess potential benefits, the researchers analyzed 10 years' of accident data and National Transportation Safety Board (NTSB) reports to estimate whether or not, if the proposed standards had been implemented previously, there would likely have been a change in the survivability. As a result of the information presented in ACRP Web-Only Document 7, airport practitioners have requested an in-depth examination of the NFPA and ICAO standards. This research will expand the analysis of historical accident data within the context of specific NFPA and ICAO changes to ARFF staffing, reduction in ARFF response time, increase in the airport area to be served within the response time, and increase in ARFF equipment. Specifically, the question is: to what extent could the proposed ARFF standards be expected to mitigate risks and accident fatalities at airports? This research should include either a statistical analysis or another modeling method to assess how each element in the NFPA and ICAO standards differs from current FAA regulations and the potential impact such differences might have made to accident history. At a minimum, 20 years of accident data should be used in conducting a statistical analysis of the proposed standards in terms of how such standards could prevent or reduce the number of injuries/fatalities. Then, using information obtained from ACRP Web-Only Document 7 and other relevant literature in the area of assessing the value of mitigating a human fatality or serious injury, the researchers should assess the economic costs and benefits of the proposed changes.

PY - 2010/02//Final Report
SP - 25p
AB - Wildlife collisions (wildlife strikes) with aircraft pose a serious risk to aircraft and cost civil aviation in the United States an estimated $490 million annually. Traditional putrescible-waste landfills are very attractive to and are used by many birds, especially gulls, creating a hazard to aircraft if located near airports. The Federal Aviation Administration currently recommends that the location of municipal solid waste landfills and trash-transfer facilities should not be within 5 statute miles of an airport. Little information is available regarding the attractiveness of trash-transfer facilities to wildlife and the potential risk to aviation, particularly on a national scale. The objectives of this study were to (1) document wildlife use of trash-transfer facilities and (2) determine if the building design or the on-site management characteristics of trash-transfer facilities influence their attractiveness to wildlife species. Twenty-nine trash-transfer facilities and four control sites, located in seven states (representative of various U.S. geographical regions) were studied. Wildlife (primarily birds) abundance and activity were quantified at each facility and control site twice per week for one year.

AB - As part of a multiple-year Federal Aviation Administration (FAA) Airport Safety Technology Research and Development Program, avian radar units were deployed at the Seattle-Tacoma International Airport and the Naval Air Station Whidbey Island, Oak Harbor, Washington, by the University of Illinois Center of Excellence in Airport Technology. The deployment activities included identification and selection of radar vendors and products, contracting for radar system deployment, site selection for radar placement, completion of FAA obstruction and frequency applications, installation, and operation of the radar systems. Although this document provides a general protocol for avian radar deployment and addresses a wide range of issues associated with radar use in the complex environment of a typical civil airport, the actual activities that must be completed for avian radar deployment will be site- and situation-specific.

TI - Estimation of Landing Stopping Distances from Flight Data
PY - 2010/02//Final Report
SP - 26p
AB - The need for improved capacity at airports to accommodate the rapid growth of air traffic has led to the investigation of operational landing performance as a safe and feasible means to increase the traffic flow. While the capacity issue becomes important, it is imperative that the increase in capacity does not let safety decline. A key task is to investigate the airplane landing performance to provide operations safety guidelines for reducing the risks of incidents and accidents associated with new technologies and procedures. For this, a clear knowledge of the day-to-day landing operations is required. The objective of the present study was to derive and analyze methods for calculating the full-stop landing distance from flight operational data. In total, eight methods have been defined to calculate the ground distance from actual landing data. All these variants have been implemented in the processing software. After reprocessing all available cases, the statistical properties and possible correlations of each variant were investigated and presented. Based on these results, it was concluded that ground stopping distances obtained with the maximum instantaneous deceleration approach may be considered as the most useful or realistic candidate to serve as an indicator for the actual airplane landing performance.

AB - The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) is used by the Federal Aviation Administration to assess psychopathology in air traffic control specialist applicants after a conditional offer of employment is extended. Two groups are compared in this study on their level of Scale K, which is used as a measure of defensiveness (putting one’s best foot forward – “faking good”), but which may be influenced by socioeconomic status and education. Group 1 had already been hired and took the MMPI-2 as part of a voluntary research protocol while in training. Group 2 took the MMPI-2 as part of their medical screening process for hiring. There was a significant difference between the two groups (2 indicated a higher level of K than 1) on the level of K, suggesting that K is likely measuring defensiveness. Group 1 faced no consequences for their results, while Group 2 faced potential additional psychological assessment as a consequence of their MMPI-2 performance, and possibly even ultimate medical disqualification. While the hypothesis that groups would differ on K as a function of testing circumstances was supported, the hypothesis that K would rise as a function of education was not.

TI - False Carbamazepine Positives Due To 10,11-Dihydro-10-Hydroxycarbamazepine
Breakdown in the GC/MS Injector Port
PY - 2010/02//Final Report
SP - 12p
AB - During the investigation of aviation accidents, postmortem specimens from accident victims are submitted to the Federal Aviation Administration’s Civil Aerospace Medical Institute (CAMI) for toxicological analysis. A case recently received by CAMI screened positive for the anticonvulsant medication carbamazepine (Tegretol®) by gas chromatography/mass spectrometry (GC/MS). The carbamazepine found during the routine screening procedure was subsequently confirmed using a carbamazepine-specific GC/MS procedure. Concurrently, it was discovered that the accident victim had been prescribed oxcarbazepine (Trileptal®). Oxcarbazepine is nearly structurally identical to carbamazepine and is metabolized by cytosolic enzymes in the liver to the active compound 10,11- dihydro-10-hydroxycarbamazepine. The carbamazepine initially found in this case was present due to the breakdown of the active oxcarbazepine metabolite in the GC/MS injector port. In the current study this conversion is investigated, the percentage of carbamazepine formed at various injector port temperatures is determined, and these three compounds are quantified in nine fluid and tissue specimens from the case in question. Lastly, liquid chromatography/mass spectrometry (LC/MS) was used to demonstrate the absence of carbamazepine, and its formation, in the same specimens.

TI - Considering and Evaluating Airport Privatization
AB - Interest in airport privatization is increasing, especially as local and regional governments look for ways to make their airports as efficient, competitive, and financially viable as possible. Consideration by communities, governing boards, airport officials, and other stakeholders on whether to privatize all or part of an airport is a significant decision with long-term impacts. As such, the decision-making process must ensure that a thorough and complete review is undertaken, so financial and other implications of privatization are fully understood and, hence, an informed, transparent decision can be made. Experience in the United States with the wide range of options for full and partial privatization of airports is limited. Private-sector participation in airports--through ownership, management, or new investment programs--can take many forms, including outright sale of assets; management contracts; public-private partnership (P3) agreements; long-term leases; design-build-finance-operate; and other private finance initiatives. Airport privatization has been adopted or considered in various forms at many foreign and a limited number of U.S. airports. The Airport Privatization Pilot Program, under 49 U.S.C. Section 47134, provides a limited number of airports in the United States with a vehicle for airport privatization and continues to generate discussion among airport operators and owners, governing boards, and airport officials. Some airport proprietors have prepared applications to participate in the program using various models for the privatization of U.S. airports. As the discussion of these issues continues, U.S. airport stakeholders require an objective presentation of the international experience with airport privatization and the relative advantages and disadvantages of privatization for U.S. airports. The objective of this research is to develop a guidebook on airport privatization that assists airport proprietors, policymakers, and other relevant stakeholders as they consider and analyze the potential advantages and disadvantages of implementing various approaches to airport privatization.

AB - Applied Pavement Technology, Inc., with assistance from Robinson Engineering Company, updated the airport pavement management system (APMS) for the Iowa Department of Transportation. During this project, pavement conditions at Estherville Municipal Airport were assessed in September 2009 using the pavement condition index (PCI) procedure. During a PCI inspection, the types, severities, and amounts of distress present in a pavement are quantified. This information is then used to develop a composite index that represents the overall condition of the pavement in numerical terms, ranging from 0 (failed) to 100 (excellent). The PCI number provides an overall measure of condition and an indication of the level of work that will be required to maintain or repair a pavement. The distress information also provides insight into what is causing the pavement to deteriorate, which is the first step in selecting the appropriate repair action to correct the problem.

TI - Calibration of Faarfield Rigid Pavement Design Procedure
PY - 2010/01//Final Report
SP - 73p
AB - The Federal Aviation Administration (FAA)-developed Rigid and Flexible Iterative Elastic Layer Design (FAARFIELD) is a computer-based thickness design procedure for airport pavements. For rigid pavements and overlays, the procedure combines a three-dimensional finite element analysis of the rigid pavement system with a performance/failure model based on full-scale traffic tests. For flexible pavements, FAARFIELD uses the same structural response and failure models as LEDFAA version 1.3. The updated rigid pavement failure model in FAARFIELD is based on full-scale tests results from the National Airport Pavement Test Facility and a re-analysis of historical full-scale tests conducted by the U.S. Army Corps of Engineers prior to the 1970s. The FAARFIELD design procedure is intended to supersede the pavement thickness design curves in FAA Advisory Circular (AC) 150/5320-6D. The design curves are considered adequate for traffic mixes including aircraft up to dual-tandem aircraft gears, including the Boeing 747, but cannot be used for newer models with more complex gear geometries. Since it is desirable that rigid pavement thickness designs performed using FAARFIELD not deviate too greatly from equivalent designs using the existing design charts when the design aircraft mix is restricted to the older models, a calibration study was performed. Based on this study, a calibration factor equal to 1.12 was applied to FAARFIELD design stresses to ensure that FAARFIELD rigid pavement design thicknesses are compatible with the earlier procedure for aircraft traffic up to and including the B747. An additional analysis was performed comparing the calibrated FAARFIELD designs with designs based on a modification of the AC 150/5320

TI - Effects of Video Weather Training Products, Web-based Preflight Weather Briefing, and Local Versus Non-Local Pilots on General Aviation Pilot Weather Knowledge and Flight Behavior, Phase 1
PY - 2010/01//Final Report
SP - 46p
AB - This research has two main phases. Phase 1 investigated three major questions: 1) Do video weather training products significantly affect general aviation (GA) pilot weather knowledge and flight behavior in marginal meteorological conditions? 2) How are modern Web-based weather products used during GA preflight briefing? 3) Do local Oklahoma GA pilots differ appreciably from other pilots in either weather knowledge or weather-related flight behavior? Fifty GA pilots took a general weather knowledge pre-test, followed by exposure to either one of two weather training videos (the Experimental groups) or to a video having nothing to do with weather (the Control group). They next took a post-test to measure knowledge gain induced by the training product. Finally, they planned for, and flew, a simulated flight mission through marginal weather from Amarillo, TX, to Albuquerque, NM. Question 1: Few highly significant, direct effects were found for the two 90-minute video weather training products all by themselves. Follow-up multivariate modeling implied that a combination of higher pilot age, receiving either weather training product, and takeoff hesitancy could significantly, correctly predict 86.7% of diversions from deteriorating weather and 77.8% of full flight completions. However, we must conservatively conclude that weather knowledge and GA weather flying behavior are complex and unlikely to be profoundly changed by a single, brief training product. Phase 2 will address this issue. Question 2: The data-collecting emulation of www.aviationweather.gov suggested that mere time spent on preflight briefing was not a good predictor of either quality of preflight briefing or subsequent flight safety. Nonetheless, these data are just an opening look at what should eventually be a far more intensive study of modern weather briefing and its relation to flight safety. Question 3: No important differences were seen between local and non-local pilots. These findings imply that CAMI studies are likely to be generalizable to the national population of U.S. GA pilots.

TI - Examining Smoking-Induced Differential Gene Expression Changes in Buccal Mucosa
PY - 2010/01//Final Report
SP - 30p
AB - Gene expression changes resulting from conditions such as disease, environmental stimuli, and drug use can be monitored in the blood. However, a less invasive method of sample collection is of interest because of the discomfort and specialized personnel necessary for blood sampling, especially if multiple samples are being collected. Buccal mucosa (cheek swabs) are easily collected and may be an alternative sample material for biomarker testing. A limited number of studies, primarily in the smoker/oral cancer literature, address this tissue’s efficacy as an RNA source for expression analysis. The current study was undertaken to determine if total RNA isolated from buccal mucosa could be used as an alternative tissue source to assay relative gene expression. In this study, qPCR and microarray analyses were used to evaluate gene expression in buccal cells. Initially, qPCR was used to assess relative transcript levels of four genes from whole blood and buccal cells collected from the same seven individuals at the same time. The RNA isolated from buccal cells was degraded but was of sufficient quality to be used with RT-qPCR to detect expression of specific genes. Second, buccal cell RNA was used for microarray-based differential gene expression studies by comparing gene expression between smokers and nonsmokers. An amplification protocol allowed use of 150-fold less buccal cell RNA than had been reported previously with human microarrays. The authors report here the finding of a small number of statistically significant differentially expressed genes between smokers and nonsmokers, using buccal cells as starting material. Gene Set Enrichment Analysis confirmed that these genes had a similar expression pattern as results from another study. The results suggest that despite a high degree of degradation, RNA from buccal cells from cheek mucosa could be used to detect differential gene expression between smokers and nonsmokers. However, the RNA degradation, increase in sample variability, and microarray failure rate show that buccal samples should be used with caution as source material in expression studies.

TI - Effect of Deicing and Anti-Icing Chemicals on HMA Airfield Runways
PY - 2010
SP - 16p
AB - The purpose of Airfield Asphalt Pavement Technology Program (AAPTP) Project 5-3 was to investigate the performance of hot-mix asphalt (HMA) airfield pavements subjected to deicing and anti-icing chemicals (DIAIC). The most commonly used DIAICs include potassium acetate, sodium acetate, urea, and ethylene and propylene glycol. Recently, several Nordic countries have reported what appears to be damage in HMA pavements related to the use of DIAICs. The exact mechanism of this damage is not clear, although it appears to be a form of moisture damage accelerated by the low surface tension and relatively high density of many DIAIC solutions. DIAIC-related damage does not appear to be common in airfield pavements in the U.S. and Canada. If it is suspected that an HMA mixture is susceptible to DIAIC-related damage, a simple procedure called the immersion tension test can be used to perform an evaluation. In cases where DIAIC-related damage is a problem, mixture performance can be improved by using a stiffer binder and/or by incorporating hydrated lime into the mixture. When an HMA mixture prone to DIAIC-related damage is used in an airfield pavement, it is essential to thoroughly compact the pavement to reduce the air voids to the lower end of the specified range.

TI - Guidelines for Use of Highway Specifications for HMA Airport Pavements
PY - 2010
SP - 16p
AB - Airfield Asphalt Pavement Technology Program (AAPTP) Project 06-05 called for the development of guidelines to be used by practicing airport pavement design engineers on the utilization of state highway hot mix asphalt specifications for use in airport pavements. Federal Aviation Administration (FAA) specifications (P-401, P-401 Superpave and P-403) were first reviewed for current criteria acceptance ranges. State specifications were gleaned to identify general topical areas. Interviews were conducted with each FAA Region Engineer and select State Aviation Offices to gain a better insight as to when, how, which and where state specifications were utilized for airfield projects. Public Law and FAA Orders pertaining to the use of state specifications for airfields were also reviewed. From the above reviews and interviews, a draft guideline document in the language and format of a draft FAA Engineering Brief (EB) was developed that an experienced engineer could use to develop a state standard airport pavement (SSAP) specification for airports <60,000# aircraft gross weight (AGW). In the draft EB-XX, critical elements were listed as well the recommended approach of how each was to be addressed in order to ensure equal quality and performance as expected with a P-401 mix. The critical elements were traffic, materials, composition, construction, acceptance, quality control, measurement and payment. The draft EBXX was continually refined through a series of test cases on 10 different state specifications, representing a variety of FAA regions and climatic environments.

TI - Hybrid Reflective-Crack Relief System at Greater Peoria Regional Airport: A Case Study
PY - 2010
SP - 17p
AB - Reflective cracking continues to be a major contributor to premature deterioration of asphalt overlays. The design methodologies for asphalt overlays are predominantly empirical, hindered by a lack of fundamental understanding of reflective cracking mechanisms and a shortage of validated damage models. This paper describes a comprehensive reflective cracking study involving instrumented field sections, laboratory testing, and advanced numerical modeling techniques. In coordination with the Illinois Division of Aeronautics, a series of test sections were constructed at the Greater Peoria Regional Airport (GPRA) in central Illinois. In particular, a novel high-performance, partial-depth composite patching method was developed for retardation of reflective cracking over an existing pavement with 50 mm wide thermal cracks. A hybrid reflective crack relief system was designed and installed, which involved a combination of a strain tolerant interlayer mixture used in conjunction with a fiberglass reinforcement grid applied in wide strips. Fundamental laboratory tests, including low-temperature creep, strength, and fracture tests were conducted on overlay and interlayer materials. Finite element analyses of field test sections were conducted, including viscoelastic bulk material modeling and cohesive zone fracture modeling. Results of parametric analyses conducted to calibrate the numerical models to measured responses caused by thermal cycling are presented. Field performance data is also presented and compared to historical performance data relating to traditional overlay systems used at GPRA, showing a significant increase in performance for the new hybrid interlayer system. The comprehensive lab, field, and modeling study provides significant new insight towards the mechanisms of reflective cracking in airfield pavements and its mitigation.

TI - Delamination Detection of HMA Airport Pavements with NDT Devices
PY - 2010
SP - 16p
AB - Sufficient bonding between the hot mix asphalt (HMA) layers is essential to ensure the desired structural capacity of a pavement. Delamination or debonding problems are particularly more severe on airfield pavements, due to higher traffic loads applied by aircrafts. Further progression of delamination may result in stripping of the lower layers due to the intrusion of moisture or may develop other dangerous distresses such as foreign object debris (FOD). Rapid nondestructive test (NDT) methods to determine the existence and extent of delamination in asphalt pavements are needed. In this paper, the existing NDT procedures and equipment that have the potential to address the problem were identified and their effectiveness and potential for success were evaluated. The identified NDT methods, which included the Ground Penetrating Radar, Thermography, sonic/seismic and impulse response, were evaluated on a controlled pavement section that was specifically constructed with various levels of debonding at different depths and with different asphalt mixes. The theoretical and practical strength and limitations of different methods are discussed in this paper.

PY - 2010
SP - 19p
AB - This paper describes an outdoor full-scale test led by Airbus S.A.S in partnership with the French authorities DGAC-STAC, LCPC, LRPC-T, MICHELIN and VANCOUVER² to improve experimental and theoretical knowledge related to the effects of aircraft internal tire inflation pressure on the behavior of and damage to flexible pavement. Since some modern aircraft have tire pressures exceeding 15 bar, the tests focus on pressures from 15 bar to 17.5 bar. The experimental pavement located on the Toulouse-Blagnac airport in France includes up to seven different test sections, representative of current airfield flexible pavement worldwide. Variant parameters from one section to another are thickness of AC surface layer and its performance in respect of rutting, and surface treatment as grooving. The aircraft simulation vehicle drives four dual-wheel gears sufficiently spaced enough in order to prevent from any interaction between them, making it possible to test two different tire pressures (15 and 17.5 bar) and two weights per wheel (ultimate weights, 28.5 and 33.2 tons) simultaneously. The seven test sections are instrumented to measure resilient strains, and resilient and permanent displacements (rutting). The structure has been initially designed according to the French airport pavement design method, for 10,000 passes of B747-400 gear. Tests will continue until the simulator runs are no longer possible due to the high rut depth level.

PY - 2010
SP - 15p
AB - As a preliminary to a project to measure pilot’s subjective response to vertical cockpit vibrations in ground maneuvers, the software of the Boeing 737 full-motion simulator located at the on Federal Aviation Administration (FAA) Mike Monroney Aeronautical Center in Oklahoma City has been modified to enhance the representation of cockpit response to pavement roughness. Modifications made to the software include the ability to load longitudinal elevation profiles measured on airport pavements, suppression of the generic roughness simulation models, and the addition of flexible body modes to the flight system dynamic simulation model. The modifications are described, together with the procedure used to transfer the computed vertical cockpit accelerations to the motion system. Cockpit accelerations computed in response to a number of test profiles are compared with accelerations measured with a physical accelerometer positioned below the pilot’s seat in the simulator cockpit. Comments made by two test pilots regarding the fidelity of the cockpit acceleration responses during taxiing, takeoff, and landing are reported. The pilots considered the responses to feel realistic except for the representation of background roughness, induced tire noise and the absence of responses to passing over centerline lights and concrete pavement joints.

In the past, the tools available to airport personnel were limited to human observation, which documented species and numbers, followed by scientific analysis. With the advent of radar technologies and the availability of relatively inexpensive radar systems, a new tool was introduced to airport safety management systems. Avian radar provides an opportunity to extend observational capabilities to 24/7 time frames and the ability to expand spatial coverage in both distance and altitude.

TI - A Case Study - Upgrade of the Terminal Apron at Mumbai International Airport
PY - 2010
SP - 16p
AB - Chattrapati Shivaji International Airport (CSIA) at Mumbai, India, currently handles in excess of 21 million passengers and 465,000 metric tonnes (512,500 Tons) of cargo per annum. These figures are forecast to grow to 40 million passengers and 1 million metric tonnes (1.1 million Tons) of cargo per annum by 2015. In April 2006, Mumbai International Airport Private Limited (MIAL) signed an Operational, Management and Development Agreement with the Airports Authority of India (AAI) to operate, maintain, develop, design, construct, upgrade, modernize, finance and manage the airport for a period of 30 years, with an extension option for a further 30 years. In 2007, Larsen & Toubro Limited, ECC Division (L&T) were awarded a contract by MIAL to upgrade the airport as part of the CSIA Expansion and Renovation Program. MIAL is a joint venture company owned by a GVK Group consortium and Airports Authority of India (AAI). As part of the CSIA Expansion and Renovation Program, the existing international terminal and the associated aprons are being replaced. The project consists of the replacement of approximately 540,000 m2 of existing rigid pavements with over 950,000 m2 of new pavement. The aprons will be in use throughout the 3 year construction period, and are currently operating near saturation traffic levels. Detailed staging has been implemented to achieve a balance between the operational use of the aprons and adequate work faces to achieve construction efficiency. The project timeline is further complicated by an annual monsoon period of four months duration. The reconstructed aprons have been designed to International Civil Aviation Organization (ICAO) standards utilizing FAARFIELD software for pavement design. Geometric and pavement designs were designed in accordance with ICAO Annex 14 and ICAO Aerodrome Design Manual Parts 1, 2 and 3. FAA Advisory Circular 150/5320-6E was used as a guide for pavement designs and detailing. The forecast usage for each apron taxilane and aircraft stand was analyzed and pavement thicknesses were determined using FAARFIELD. The aircraft parking stands were designed using fewer departures but with correction factors to cater for reduced wander. Both designs gave similar results, hence a uniform pavement thickness was adopted throughout. The majority of the new apron footprint rests over existing concrete and flexible pavements which will be used as a foundation for the new rigid pavements to economize the design and expedite construction. The apron requires vertical shape correction which leads to varying degrees of cut and fill over the existing surface. The existing apron pavement will be reused in a number of ways, including rubblization of the existing concrete pavements, recycling of other concrete pavements for use as subbase where rubblization is not feasible, and removal of the existing wearing courses and utilization of the underlying pavement courses as subbase. Where none of this is possible due to inadequate cover over subgrade, new full depth pavements have been adopted. The subbase for the new concrete pavements is therefore a mixture of rubblized concrete, existing subbase and new subbase. Utilizing rubblised concrete as a subbase for new rigid pavements is a highlight of the project.

TI - High Tire Pressure and Temperature Effects on Hot Mix Asphalt Concrete Permanent Deformation Using Customized Asphalt Pavement Analyzer (APA)
PY - 2010
SP - 14p
AB - New pavement standards are needed due to the advent of newer aircraft exceeding the current International Civil Aviation Organization (ICAO)’s 217 psi (1.50 MPa) tire pressure limit. The Federal Aviation Administration (FAA) owns a customized Asphalt Pavement Analyzer (APA) which can apply higher tire pressures and loads for aircraft loading conditions. Cores with 6 inches (152 mm) diameter by 3 inches (76 mm) high were taken from the FAA’s National Airport Pavement Test Facility (NAPTF) high tire pressure area and prepared for tests at two different contact pressures of 100 psi and 250 psi using the customized APA. The test was also performed at two different temperatures of 70°F and 140°F. The APA test results were analyzed in terms of rut depth and rut slope with different tire pressures and temperatures. The recorded rut depth measurements by the APA were compared and confirmed by manual measurements after the testing. The gradation of the Hot Mix Asphalt (HMA) mix in the cores is provided with test results. The results show that the rut depth increased significantly with higher contact pressures and temperatures. Also, the permanent deformation was more sensitive to temperature than to the contact pressure changes.

TI - Managing Data from Avian Radar Systems
PY - 2010
SP - 12p
AB - Avian radar systems have been deployed to several airports in a performance assessment program developed by the University of Illinois Center of Excellence for Airport Technology Airport Safety Management Program (CEAT) for the Federal Aviation Administration Research and Development Branch, AJP63. As part of the CEAT Performance/Capability Assessment Program for Avian Radar Systems at Civil Airports, avian radar deployment began in 2006 with the acquisition of radar units and completion of initial calibration testing and licensing. The deployments were intended to assess this new technology at civil airports, exploring a wide range of technical and operational issues, including issues of data and data management. Data generated by avian radar can support airport safety management systems by improving the understanding of the movements and the timing of movements of birds on and around an airport. Even when avian radar cannot be monitored in real-time, the analysis of archived data can support directed management efforts to reduce or eliminate bird hazards through such applications as evaluating avian risks on or around the airport or predicting hazardous events at specific locations. Thus, the ability to review such archived data is essential to the successful use of avian radar as a tool for improved airport safety. However, the magnitude of data produced by the radar can create an obstacle to achieving this goal. Under normal operation, a single radar will produce approximately 150 gigabytes (GB) of processed data a year, consisting of plots-and-tracks files that support a range of post-processing options. In addition, records of raw radar data, which provide maximum opportunity for post-collection analysis, can require many GB of data storage in a very short time. After the initial deployment of an avian radar system at the Naval Air Station Whidbey Island, Oak Harbor, WA (NASWI) and a second system at the Seattle Tacoma International Airport (SEA), radar data was generated, and data analysis and management became a major and continuing effort in the performance assessment program. Although the basic data products of avian radars are well understood, the format and complexity of the data stream and the methods for management of high-frequency and long-term data were not well-defined for this technology and for application in an airport environment. Beginning with the acquisition of the first radar units, data issues were explored by CEAT and procedures were developed to acquire, process, analyze, and interpret radar data. Based on this experience, CEAT developed a comprehensive data management system that has evolved from on-site recording of radar data to a networked system that automatically processes and displays data, including a real-time display of radar detections. This paper will review the general characteristics of radar data generation with particular focus on plots-and-tracks information used in post-processing. Post-processing will be reviewed, illustrating the information products developed by CEAT.

AB - The site selection process is a critical element of eventual avian radar performance on a civil airport. Finding an acceptable site requires prioritizing identified needs and then carefully analyzing competing issues. From a wildlife detection perspective, the most important criteria for site selection are providing good detection capability for known critical areas on the airport. Critical areas are those locations where observational data suggests a high hazard potential due to site attractants or the actual use of the area known from observations. From a radar operations perspective, the most critical criterion is minimizing clutter interference for critical areas. These two factors can generally be accommodated by several locations. The final location can then be determined by considering infrastructure needs, such as the enclosures needed for the radar system (including towers or other structures required for the radar antenna), power supply, and the availability of high speed connectivity. Finding the correct balance between these components is the first step in bringing an avian radar system on-line at any civil airport, and each component creates unique challenges to the siting process. The process is further complicated by the requirement for Federal Aviation Administration (FAA) Form 7460 approval, which addresses issues of possible obstructions and frequency interferences and is required prior to the placement of the radar on the airport.

TI - General Safety Management Systems Gap Analysis Survey for US Airport
PY - 2010
SP - 15p
AB - The cost of accidents has become critical for the aviation industry; however, currently, most airports deal with safety issues in a reactive manner and without a systematic approach to optimize available resources and to minimize risk. Moreover, the International Civil Aviation Organizations (ICAO’s) Contracting States have agreed to that the implementation of Safety Management Systems (SMS) will become an international standard effective in November 2010. This decision represents one of the most significant changes in the regulatory framework for the operation of airports in recent years. The Federal Aviation Administration (FAA) is strongly supporting the adoption of such an international standard and intends to implement SMS at U.S. airports in a way that complements the requirements of 14 CFR Part 139, Certification of Airports. The FAA is now evaluating the best way to introduce an SMS requirement and plans to issue a notice of proposed rulemaking (NPRM) about SMS in the near future. As part of the actions already taken in that direction, the FAA has developed an SMS advisory circular for airports, initiated the second SMS Pilot Study and is sponsoring the development of additional guidance, which this research is a part of. As part of an Airport Cooperative Research program (ACRP) project to develop a Guidebook on Airport Safety Management Systems, two surveys were conducted to compile the perceptions of airport personnel. The first survey had the objective to identify the SMS elements in place at Part 139 airports. The second survey was conducted in the form of interviews with key personnel of airports participating in the 1st FAA Pilot Project on Airport SMS. The latter had the objective of obtaining feedback for a draft Guidebook prepared by the research team. These interviews offered another opportunity to conduct a general gap analysis with 15 participating airports. An analysis of the data gathered from the airport surveys was performed to assist in determining what SMS strengths and weaknesses exist within US airports. Based on the analysis, an assessment is made on existing SMS elements available at US airports, and the Guidebook on airport SMS (ASMS) should address these differences. As a secondary benefit, the results of the survey provided insight, although with limitations, into the present safety culture at different airport locations, airport types and for the airport community as a whole. This paper presents a summary of the results obtained from the airport surveys. The analysis of survey responses and interviews provided a general gap analysis for ASMS on Part 139 airports.

TI - Design of Hot Mix Asphalt for Airfield Pavements Using the Superpave Gyratory Compactor
PY - 2010
SP - 16p
AB - Approximately 90 percent of America’s paved runways are paved with hot mix asphalt (HMA). However, only a small percentage of the total HMA placed in the United States is used for airfields. Historically, HMA for airfield pavements has been designed using the Marshall mix design method. Conversely, the vast majority of non-airfield HMA pavements placed during the last 5 to 7 years have been designed using the Superpave mix design system. The percentage of HMA that is being designed using the Superpave mix design system is increasing every year. Therefore, mix design experience is being gained by HMA contractors, commercial labs, and industry personnel in the area of Superpave. Since the Marshall mix design procedure is becoming the exception to the rule, industry personnel are becoming increasingly unfamiliar with the Marshall mix design method. As such, the airfield industry needs to implement the Superpave mix design system in airfield pavements in order to benefit from the industry’s experience with Superpave.

The Flight Safety Foundation has indicated that as air traffic is on the rise, issues such as mitigating human error and training are critical to continuing to ensure safe working environments, not to mention the need to adopt new technologies to enhance safety and support an economically viable industry. As such, new tools and resources to help manage the workload and improve its efficiency, while maintaining and or enhancing safety, are appreciated by airport operators.

TI - Guidelines for Airfield Rubblization
PY - 2010
SP - 16p
AB - Airfield Asphalt Pavement Technology Program (AAPTP) Project 04-01 called for the documentation of the state of the art in rubblization technology for airfield pavements and for developing guidelines covering project feasibility, thickness design/material characterization, quality assurance criteria and methods, and construction/equipment issues. The AAPTP 04-01 Final Report can be found at www.aaptp.us. This paper is an abbreviated description of the key findings from that report. An extensive review of the literature on rubblization for both highways and airfields was conducted under this project. A comparison of current rubblization specifications was provided, along with a summary of all airfield rubblization projects known to date. The combination of thin slabs (less than 9-inches) and weak underlying support (little to no subbase and soft subgrade that is often saturated) can produce marginal stability and difficulty in effectively rubblizing the portand cement concrete (PCC) to specified criteria. A suggested criteria and protocol was developed for assessing the suitability of rubblization as a rehabilitation technique if the concrete slabs are less than 9 inches thick and have weak underlying support. Even when a significant portion of a project is assessed with a moderate to high level of risk, there are a number of recommendations and considerations in the planning, design and construction stages to optimize success. Structural characterization of the rubblized layer is covered; along with other thickness design considerations such as minimum overlay thickness. To determine appropriate design modulus values for a rubblized layer, the literature was reviewed for studies where back-calculated modulus values of rubblized layers (Erub) were determined. In addition, new back-calculations were performed for several projects, providing a total of 17 unique rubblized sections. The average in-place Erub value was 205 ksi, with the absolute range being 100-430 ksi. Quality control and assurance of the rubblization process is addressed, providing recommendations regarding test strips, test pits and particle-size acceptance criteria. Guidance on equipment and other issues are also covered.

PY - 2010
SP - 14p
AB - The complete failure of a concrete pavement can be divided into three stages: from brand new to a crack initiated; from the first crack initiation to full depth and full length; and from one crack to many cracks those lead to end of pavement service life. The validation of “fatigue failure” concept embedded in Federal Aviation Administration (FAA) design specifications since 1970’s was based on an assumption: the concrete pavement strength is relatively close to the concrete beam flexural strength following ASTM C78. In past ten years, this assumption has been repeatedly verified by the full scale tests for different pavements under static and slow rolling loads at the Federal Aviation Administration’s (FAA’s) National Airport Pavement Test Facility (NAPTF). However, different conclusion was obtained recently based on experimental studies in [8] and [9]: the pavement strength is 2.8 times in average higher than the beam flexural strength. Their test procedures were reviewed and data were re-analyzed. It has been found that the test results themselves are reliable, but the analysis procedure leads to an overestimate of pavement strength. Three-stage failure was clearly recorded from the tests. The response at the end of second stage was analyzed using linear-elastic model that is only valid in the first stage. After the data is reanalyzed up to the end of the first stage, the conclusions by the FAA become similar.

AB - Budget cuts and decreased airline capacity have caused most airports to scale back their capital programs. Still, over the past few years more and more airport owners have been looking for new methods of designing and building facilities quickly and economically. One project delivery method that is gaining popularity across North America is Design/Build (D/B). D/B projects combine the design and construction phases into one contract that is awarded to a single entity, usually a joint venture made up of consultants and contractors. In D/B projects, the design firms’ role may be significantly different than traditional design/bid/build (D/B/B) projects. These role changes can create significant opportunities for airport consultants and project sponsors, but they can also pose challenges and risks. This paper summarizes the findings of the Innovative Pavement Research Foundation research report IPRF 01-G-002-06-1 Using Design/Build Acquisition for Airfield Pavements including best practices for the successful use of the D/B method for airport pavements.

TI - Bird-Aircraft Strike Threat Assessment Using Avian Radar Information
PY - 2010
SP - 12p
AB - Bird-aircraft collisions or bird strikes have been a major concern to aviation safety since the early days of aviation. The number of bird strikes has increased sharply over recent years and is expected to keep increasing in the United States (US) and perhaps throughout the world due to the increasing air traffic and bird population. More than 12,500 bird strikes occur every year to US civil and military aircraft, as reported in Richardson. Richardson's financial evaluation shows that bird strikes cost the U.S. commercial aviation over $600 million every year. Birds near the airport post serious threat to the aircraft. Statistical analyses in Transport Canada, Cleary et al. and Federal Aviation Administration (FAA) show that about 91% of departure collisions and 83% of arrival collisions occur within 5 nautical miles (9260 meters) of the airport and 92% of all bird strikes happen below 3000 feet (914.4 meters) relative to ground level. Because there is no effective way to influence bird activity in the air, the only chance to minimize the threat of bird strikes is to avoid flying through regions with high bird density. Therefore, evaluating bird strike threats to aircraft near the airport is a very critical element in programs to reduce bird strikes. Bird strike threat is directly influenced by bird activity in terms of bird density (bird count/area), bird body mass, collision speed and flight direction as mentioned in Tedrow, Dolbeer and Transport Canada. Although the threat is generally assumed to be higher in areas where bird densities are high, the result may not be consistent with the assumption because of the area location (e.g. close to or far away from aircraft flight routes), bird species and bird flight behavior. Collision speed is important where more damage is likely at higher speeds, so collisions at higher altitude may be more damaging because speeds are greater. It is more meaningful to evaluate bird strike threat in some critical target areas inside and outside the airport where bird strikes mostly occur. Radar has been proven to be a useful and effective tool in bird movement study since the 1960s in Eastwood and Gauthreaux et al. With radar, information collected for a target can include velocity, heading direction, latitude, longitude and altitude. Radars function around the clock and operate effectively under poor hearing and viewing conditions. Advancement in radar and processing technology support analysis of bird movement dynamics. In this study, the authors use radar to collect bird activity data to further evaluate bird strike threats to aircraft operations at the Naval Air Station Whidbey Island (NASWI), located in Oak Harbor, Washington. The overall wildlife management program at NASWI is designed to improve safety through bird hazard management. The NASWI installation has two sections: Ault Field, which is the focus of aircraft operations, and the Seaplane Base, which provides administration and housing support for NASWI staff. The threat analysis focuses on Ault field, located on the Strait of Juan de Fuca. The Strait of Juan de Fuca is a large water body connecting the Georgia Strait and Puget Sound to the Pacific Ocean. The geographical location of Ault Field is 48° 21' 8" N, 122° 39' 15" W. As shown in Figure 1, there are two runways that form an "X" pattern: runway7/25 is oriented east/west and runway 14/32 is oriented north west/southeast. There are also several taxiways connecting runways and the military aircraft ramp areas. The Strait attracts many seabirds, and there is a large bird community that includes raptors, passerines, and waterfowl in the area. The authors objective was to evaluate bird strike threat in critical target areas on and around Ault Field using a threat assessment model.

PY - 2010
SP - 10p
AB - As part of a comprehensive performance assessment of Foreign Object Debris (FOD) detection systems at civil airports, assessments of a radar system and a hybrid electro-optical and radar detection system was conducted by the Center of Excellence for Airport Technology (CEAT). The radar-based sensor was the QinetiQ TarsierTM FOD detection system. The hybrid sensor was the Xsight FODetectTM FOD detection system. The performance assessments were designed to provide a rich data resource that could assess the performance of both individual sensors and combined sensor systems. Targets included a variety of items, some with known detection characteristics, such as radar cross sectional area (RCS) for radar-based sensors and color and surface condition for electro-optical systems. Targets also had different shapes and sizes and were made of different materials to provide target characteristics that would challenge detection systems. Assessment campaigns were scheduled over a 12-month period with the intent of testing under varied weather conditions. The performance assessment of the radar-based TarsierTM FOD detection system was initiated in 2004. It included a preliminary test at John F. Kennedy International Airport (JFK) in January 2005 and an assessment of an operational system from June 2007 to March 2008 on an entire runway at Providence’s John F. Green International Airport (PVD). The assessment of the Xsight FODetectTM FOD detection system (a hybrid sensor) began in early 2008; the Xsight FODetectTM system was installed at Boston’s Logan International Airport (BOS). This installation provided partial runway coverage with a total of five sensor units. The BOS studies were initiated in June 2008 and ended in March 2009.

AB - The uniformity of concrete material properties, particularly strength, is important to the performance of concrete infrastructure elements, and in particular airfield pavements. Since airfield pavement design methods rely on assumptions about concrete flexural strength as a primary level input, it is vital that the actual in-place concrete comply with these assumptions. In addition, to achieve consistent performance and avoid random performance problems associated with variation in the actual concrete placed, it is important that the material used be uniform in strength and other properties directly related to performance. Consequently, the airfield industry has relied upon flexural strength testing as the means for specifying and accepting airfield concrete,

Test data from full-scale aircraft gear loading conducted at the FAA’s National Airport Pavement Test Facility (NAPTF) were used to investigate the effects of wander (offset loads) on the deformation behavior of unbound aggregate layers in asphalt pavement test sections. The overall objective was to develop a better understanding of the complex rebound (recovered) and residual (unrecovered) deformation trends of granular materials due to passing of each of the 6-wheel B777 type and the 4-wheel B747 type gears for various combinations of applied load magnitudes and loading sequences (stress history effects), traffic directions, and wander positions and sequences. The NAPTF rutting performance data for the CC1 flexible pavement test sections were gathered for transverse pavement surface profiles and the individual deformations in the P209/P154 granular base/subbase layers indicated by the Multi-Depth Deflectometer (MDD) data. The unique analyses of the MDD data pioneered the use of critical transverse profile points and critical point multiplication factors to calculate individual pass residual transverse profiles. It then combined the individual profiles through an entire wander pattern to simulate the actual applied traffic on NAPTF sections and determine the creation of the residual deformation basin and the final transverse profile.

AB - Prediction and simulation of load-related reflective cracking in airfield pavements require three-dimensional models in order to accurately capture the effects of gear loads on crack initiation and propagation. In this paper, the authors demonstrate that the Generalized Finite Element Method (GFEM) enables the analysis of reflective cracking in a three-dimensional setting while requiring significantly less user intervention in model preparation than the standard FEM. This novel computational tool is used to simulate a full scale reflective cracking simulator being considered for the National Airport Pavement Test Facility (NAPTF). This paper demonstrates how numerical simulations enable the evaluation of three-dimensional crack behavior, particularly the study of vertical crack propagation versus crack channeling. These findings lead to a better understanding of the mechanisms controlling reflective cracking and help test designers in the selection of test simulator geometry, boundary conditions, and in selecting sensor types and locations.

TI - Development of Residual Stress Measurement for Concrete Pavements through Cantilevered Beam Testing
PY - 2010
SP - 11p
AB - Knowledge of residual stresses is important in understanding and predicting the performance of concrete pavements. However, there is not a standard pavement test to determine these stresses. Prior pavement research was inspired by the hole-drilling strain-gage method used in metals. This method involves drilling a small hole into the specimen and measuring the resulting stress relaxation near the hole with strain gages. The strain change is then used to calculate the residual stresses in the metal. The pavement research at the Federal Aviation Administration’s National Airport Pavement Test Facility showed the promise of using core rings to create a similar stress relaxation in cantilevered concrete beams. Testing at the University of Illinois continued the use of core rings and cantilevered beams and also introduced a method using notches. Strain gages on each beam measured the strain relaxation due to a core ring, one notch, or many notches. Strain relaxation was clearly seen in the core ring and notch beam tests, and this relaxation was most pronounced with the notch tests. Sawing a notch on both sides of a strain gage was able to relax all of the strain induced by the cantilever loading, making the residual stress calculation quite simple. A two-dimensional finite element analysis was used to parallel the testing and to learn more about the stress distributions in notched cantilevered beams.

TI - Batching Effects on Properties of Recycled Concrete Aggregates for Airfield Rigid Pavements
PY - 2010
SP - 13p
AB - The use of recycled concrete aggregates (RCA) as a substitute for natural aggregates in new concrete produces both economic and environmental advantages. The majority of recycled concrete aggregate applications for pavements have been primarily applied to support layers for roads and airfields. This paper summarizes initial work completed in partnership with the O’Hare Modernization Program to examine the effect of recycled concrete aggregates (RCA) on the concrete’s fresh and strength properties for airfield rigid pavement applications. A recent method proposed for batching and mixing recycled concrete aggregate called the two-stage mixing approach (TSMA) was evaluated in order determine its effect on the concrete’s fresh and strength properties relative to virgin aggregate concrete (VAC). The principle process for the TSMA is initially coating the recycled aggregates with cementitious paste to improve the uniformity and strength of the interfacial transition zone. This paper reports the results of an experimental program in which different percentages of recycled coarse aggregates were substituted for virgin coarse aggregates. After employing the TSMA, the workability of RCA concrete was similar to the virgin aggregate concrete. Based on the compressive and the splitting tensile strength results, the RCA should meet current strength requirements for construction of airfield concrete pavements.

PY - 2010
SP - 12p
AB - The airport pavement project requires, in general, the mass of the critical take-off aircraft; particularly it uses the load transmitted by one of the main landing rear gears; in fact the contemporary presence of two main gears on the same slab is rare. The anterior or secondary gear has essentially directional functions and it is not considered in the calculation because the load that transmits to the aircraft pavement is negligible. In this research, instead, the anterior gear of the Airbus 380 (nicknamed Super Jumbo) is examined. The Airbus A380 have all the typologies of landing gear with which the modern commercial aircrafts are equipped: directional anterior twin wheels (Nose Landing Gear - NLG), rear double tandem bearing wheels (Wing Landing Gear - WLG) and rear tridem bearing wheels (Body Landing Gear - BLG). Through a computational code FEM (Finite Element Analysis) and the predisposition of numerous models, the authors show that, for particular conditions of static load, the NLG, often neglected in the airport pavement design, determines tensile stress more elevated than those activated by the bearing rear gears WLG and BLG.

PY - 2010
SP - 17p
AB - This paper describes the use mechanistic-empirical pavement analyses together with material properties determined from laboratory tests to design and evaluate performance of thick lift hot mix asphalt (HMA) pavements for large commercial aircraft loadings. Key material properties for the HMA are obtained from shear (AASHTO T-320, ASTM D-7312) and flexural fatigue (AASHTO T-321, ASTM D-7460) tests. Use of shear test data to establish mix performance criteria for taxiways at the San Francisco International Airport (SFO) and mix design for the HMA used as the surface course for New Doha International Airport are briefly described. Examples of full depth HMA structural section design for wide body heavy aircraft (e.g., Boeing 747-400, Boeing 777-800, Airbus 380-800, and Airbus 350-800) are included. The long life pavement designs include use of conventional and modified binders for the HMA, rich bottom layers in the pavement sections, and flexural strain criteria based on laboratory fatigue tests for the HMA mixes. Associated with the design methodology is a discussion of construction considerations. Mix quality control including compaction requirements and limits on binder content and layer thickness variability as well as the use of tack coats for HMA multiple lift construction are discussed. In addition, preparation of the upper portion of the subgrade to insure proper HMA construction is discussed.

TI - Rubber Tire Buildup Removal at Hartsfield-Jackson Atlanta International Airport
PY - 2010
SP - 17p
AB - Landing areas on each of the five parallel runways at Hartsfield-Jackson Atlanta International Airport experience heavy rubber tire buildup. Ranked as one of the world’s busiest airports for more than a decade, the runways experience numerous aircraft landings each day (1,400 operations represent the peak daily arrivals in 2009). The rubber tire buildup caused by these frequent landings causes the surface frictional characteristics to creep towards unsafe conditions, requiring an aggressive maintenance plan. To combat this, the airfield operations unit conducts skid tests every two weeks, and removal of the rubber tire buildup occurs when minimum threshold values are measured. Currently the two primary arrival runways are being cleaned every four months. Throughout the years, the airfield maintenance unit has removed rubber tire buildup in different ways. From the late 1960’s to the mid 1990’s, waterblasting was the most utilized method. In the mid 1990’s, the use of steel shot blasting became more common. While readily removing rubber tire buildup and restoring safe friction values to the runway surface, both waterblasting and steel shot abrasion have had detrimental affects on the micro-texture, macro-texture and grooves of the concrete pavement. The runway pavements range from 3 years old to nearly 40 years old. Each runway is concrete-surfaced, and each has subtle differences in the concrete mix constituents comprising the concrete. These differences consist of cementitious materials and proportioning (Portland cement, fly ash, slag cements), mineral aggregates (manufactured sand and natural sands) as well as admixtures. Two of the runways have been regrooved within the last five years due to damage from the rubber removal process. Each concrete surface might perform differently under the different maintenance treatments utilized to remove the rubber buildup from the surface. Presently, the use of chemicals is used as the primary means of removal. A discussion of advantages and disadvantages of each method is summarized based on cost and schedule impacts as well as the historical friction values and pavement surface loss.

TI - Superpave Gyratory Compaction Requirements for FAA’s Hot Mix Asphalt Specification
PY - 2010
SP - 11p
AB - Superpave mix design technology for hot mix asphalt (HMA) is commonly used by the highway industry; however, HMA mix design methods for civil airport pavements are still based on the Marshall method, as included in Federal Aviation Administration's (FAA’s) P-401 specification. With the shift in the industry away from the Marshall methods, the equipment and expertise required for the Marshall designs are becoming less common. As a result, it has become necessary for the FAA to establish their specifications and mix design methods on Superpave methods using the Superpave Gyratory Compactor (SGC). For the Superpave methods to produce results and performance equivalent to the Marshall method, the volumetric mix properties must be established at a requisite number of gyrations. The primary focus of the first phase of this research, which is the subject of this paper, is to establish the number of gyrations needed to produce mixes with volumetric properties (e.g., air voids, VMA and VFA) equivalent to well performing Marshall mixes. An equivalent compaction level of 70 gyrations is proposed to replace the 75 blow Marshall compaction method in the FAA’s P401 specification. Phase II of this research, currently underway, will compare the performance of mixes designed using these two compaction methods.

PY - 2010
SP - 19p
AB - The Pavement Condition Index (PCI) procedure is a well-documented standard used by the aviation industry to visually assess pavement condition. During a PCI survey, visible signs of deterioration are observed and recorded by distress type, severity, and quantity. The results, aggregated into a score from 0 to 100, are widely acknowledged to be a consistent, objective, and repeatable tool that can be used to represent and communicate the overall condition of a pavement. When regularly applied to all of the pavements in a defined network, the PCI becomes an important tool in the management of that network. However, a significant shortcoming of the PCI procedure is that it does not adequately address materials-related distress (MRD). Without going into great detail on the development and progression of different types of MRD, there are several aspects of MRDs that affect the evaluation and management of affected pavements.

PY - 2010
SP - 11p
AB - The U.S. Army Engineer Research and Development Center (ERDC) conducted a series of full-scale traffic experiments on flexible pavement test sections to evaluate design criteria for military pavements. The experimental research objectives were to evaluate the minimum thickness of asphalt surfacing for the F-15 and C-17 aircrafts, evaluate the performance of marginal base materials in flexible pavements, and evaluate the newly developed thickness criteria for flexible pavements. Standard triaxial and repeated-load triaxial tests were conducted on the 5 granular materials used in the test sections. These tests were also conducted on CH subgrade clay having California Bearing Ratio (CBR) values of 4, 10, and 15. By closely following the protocol described in the National Cooperative Highway Research Program Report 453 for the development of laboratory test procedures for evaluating the quality of granular materials, ERDC developed test protocols to evaluate the resilient modulus and shear strength of the materials being tested. This paper presents the test protocols, example material test results, and a proposed procedure for analysis of the material test data.

AB - In 2003, the Airports Authority of Trinidad and Tobago (AATT) began construction of hot mix asphalt (HMA) overlay for Runway 10-28 at Piarco International Airport, Port of Spain, Trinidad. Due to problems with aggregate quality, overlay placement and pilot complaints on runway roughness, the paving works were suspended and the Trinidad and Tobago Civil Aviation Authority (CAA) requested that the U.S. Federal Aviation Administration (FAA) conduct a roughness survey using their airport pavement inertial profiler with their PROFAA analytical software to quantify the extent of the roughness. That survey confirmed that the pavement was rough as characterized by several commonly used roughness indexes, including simulated straight-edge, Boeing Bump Index (BBI), aircraft response, International Roughness Index (IRI), and simulated California Profilograph Index (PI). The FAA also identified several other issues associated with HMA production and placement and recommended that remedial actions be initiated to correct the problems.

PY - 2010
SP - 16p
AB - The Engineered Material Arresting System (EMAS) was jointly developed by the Federal Aviation Administration (FAA), The Port Authority of New York and New Jersey (PANYNJ), and Engineered Arresting Systems Corporation (ESCO-ZA) in the 1990’s as an alternate means of providing overrun safety when the mandated 1,000-foot-long Runway Safety Area (RSA) could not be economically achieved. The current EMAS system, EMASMAX®, manufactured (ESCO-ZA), is currently the only system that meets the requirements of FAA Advisory Circular AC150/5220-22A and is installed at 30 airports in the U.S. To date, the system has successfully arrested six overrunning aircraft, and has proven to be a reliable, efficient remedy for length-deficient runway end safety areas. Due to a lack of historical data, there have been some questions regarding EMAS’ long-term durability. In particular, there was of a lack of data regarding the ability of the system to maintain performance and survive for up to 20 years in extreme cold environments, or any quantitative method to evaluate the condition of the installed systems. This paper discusses two studies conducted by the FAA and ESCO-ZA to answer these questions: Extreme Cold Weather Testing and Development of a Field Strength Test Method. The results of the cold weather study have shown that EMAS is unaffected by extreme cold and temperature cycling, and can be expected to be durable for up to 20 years or more in extreme cold climates, while the development and certification of a field test method now provides a way to test the viability of installed beds. Combined, these studies result in a higher confidence that properly-maintained EMAS systems can survive harsh runway environments for up 20 years.

PY - 2010
SP - 13p
AB - Project sustainability is many times, if not always, linked to the U.S. Green Building Council (USGBC) Leadership in Energy and Environmental Design (LEED) certified criteria, better known as green building. But for airport pavement rehabilitation projects, the LEED certification is not available. However, sustainable construction practices have been and are currently implemented in airports around the U.S. Commercial airports such as Boston Logan and Chicago O’Hare have developed successful sustainable construction practices in their rehabilitation projects. Many engineers and contractors are already using sustainable design and construction practices in airport pavement rehabilitation projects, but may not be aware of the benefits and positive environmental impacts of their practices. This paper will highlight sustainable construction practices used at airport pavement rehabilitation projects including asphalt reclamation, concrete pavement recycling, and the traditional LEED registered process for airport buildings. The practices applied by Kimley-Horn and other aviation design professionals have been implemented in general and commercial aviation projects not only for the goal of being sustainable, but as a cost savings technique. For example, the reduction of project truck hauling has resulted in less pollutant emissions and material waste. This paper will also outline the findings of Kimley-Horn’s internal research on airport sustainable projects and the available resources for the aviation engineer.

TI - Techniques for Mitigation of Reflective Cracks
PY - 2010
SP - 16p
AB - Reflective cracks are a major concern to airport management personnel, because they can significantly reduce the service life of hot mix asphalt (HMA) overlays of airside airport pavements. Reflective cracks also pose safety problems for airfield pavements because of their potential to cause Foreign Object Debris (FOD), and loss of ride quality or smoothness. These reflective cracks have to be maintained to prevent the generation of loose aggregate and increased roughness that can be detrimental to aircraft operations. The purpose of Airport Asphalt Pavement Technology Program (AAPTP) Project 05-04 was to provide guidance for designing rehabilitation strategies of airside pavements to mitigate the occurrence of reflective cracks in HMA overlays of rigid and flexible pavements. The technical approach and data sources used to determine the effectiveness of different treatment methods was extracted from three areas: information and data included in the literature (including the comparative field studies), data and information obtained from airfields and roadway projects that have placed one to multiple treatment methods, and information from detailed site visits. The probability of success and risk factors were used to rate the reflective cracking mitigation methods. The overall rating of a mitigation method was simply determined by multiplying its probability of success and risk values. Decision trees were prepared for selecting appropriate reflective cracking mitigation techniques and methods that depend on the type and condition of the existing pavement. The decision trees were prepared based on the results from previous research studies, forensic investigation of rehabilitation strategies for the methods identified, a detailed survey of various projects, and experience documented in the literature. This paper overviews the decision tress and recommendations from AAPTP Project 05-04 for mitigation of reflective cracks in HMA overlays.

TI - Joint Load Transfer Efficiency of Rigid Pavement Considering Dynamic Effects under a Single Moving Load
PY - 2010
SP - 12p
AB - The mechanistic analysis presented in this paper is only a beginning of new approach for understanding the real joint load transfer capability on airport and highway concrete pavements. It gives up the two major assumptions those have been popularly adopted by hundreds of published papers: the load is transferred under a wheel with zero speed and with fixed position. The real load transfer in field is always under wheels with non-zero speed and with varied position at any moment. The objective of this study focuses on quantifying the dynamic effects of a moving wheel while it is crossing a joint on a pavement. The analysis is conducted using a model of two-slab system on Kelvin foundation under a moving wheel with variable speed v, different pavement damping Cs, foundation reaction modulus k and foundation damping Ck. The dynamic joint load transfer efficiency is temporarily and empirically defined by the peak strain ratio LTE(S) on the two sides of a joint. The primary findings include: (1) The higher speed of a moving wheel leads to the higher LTE(S); (2) The larger the pavement damping Cs leads to the higher LTE(S); (3) The numerical ratio c(=LTE(S)dynamic/ LTE(S)static) varies in the range 1 to 2 mainly depending on speed v and damping Cs; (4) The LTE(S )dynamic is not sensitive to foundation reaction modulus k and foundation damping Ck. Further researches are needed for appropriate applications of the new model in practice.

PY - 2010
SP - 14p
AB - As part of a comprehensive performance assessment of Foreign Object Debris (FOD) detection systems at civil airports, assessments of an electro-optical, intelligent vision system was conducted by the Center of Excellence for Airport Technology (CEAT). The performance assessments of FOD detection technologies were designed to provide a rich data resource that could assess the performance of both individual sensors and combined sensor systems. Targets included a variety of items, some with known detection characteristics, such as radar cross sectional area (RCS) for radar-based sensors and color and surface condition for electro-optical systems. Targets also had different shapes and sizes and were made of different materials to provide target characteristics that would challenge detection systems. Assessment campaigns were scheduled over a 12-month period with the intent of testing under varied weather conditions. The electro-optical FOD detection system that was the subject of this assessment was the iFerret™ FOD detection system developed by Stratech Systems, Ltd.

PY - 2010
SP - 11p
AB - The Federal Aviation Administration (FAA) has developed and continues to develop and refine NonDestructive Testing (NDT) technologies to assess airport pavement condition. Recent advances in computer hardware and software and data acquisition systems have significantly improved NDT effectiveness and value. The FAA has developed back calculation software to collect and interpret data from Falling/Heavy Weight Deflectometer equipment. This software, titled BAKFAA, was developed by the FAA and has been available for several years. Results obtained from BAKFAA can provide information on the structural capacity of the pavement layers from measured deflection basins and assuming uniform layer thickness. In addition, the FAA has developed ProFAA, an airport pavement profile evaluation program. ProFAA and BAKFAA are both available to the public at no charge with access to the source code for local modification. The most recent FAA software program currently under development is an internet based computer program for use as an Airport Pavement Management System (APMS). This software is called FAA PAVEAIR and its development is discussed below.

TI - Evaluation of Stone Matrix Asphalt (SMA) For Airfield Pavements
PY - 2010
SP - 16p
AB - Stone Matrix Asphalt (SMA) was developed in Germany over 30 years ago. Its success has led to its usage throughout Europe on both highway and airfield pavements. In 1990, an American Association of State Highway and Transportation Officials (AASHTO) led European Asphalt Study Tour introduced SMA to the United States (U.S.) SMA has demonstrated good performance on highway pavements in the U.S., but has seen little use on airfields. Recently, there has been resurgence in interest in SMA in the U.S. as a more durable paving option than Superpave or other dense-graded mixes. SMA is a gap-graded asphalt mixture with a high percentage (> 70 percent) of coarse aggregate. Gap-graded refers to the fact that SMA mixtures typically have very little material retained on the sand size sieves (e.g. between 2.36 mm and 0.075 mm). SMA is differentiated from dense-graded mixes by its coarse aggregate skeleton, consisting of a limited number of particle sizes, which carries the load. Mastic, consisting of mineral filler, fibers, and asphalt binder, fills the voids between the coarse aggregate skeleton. The percentage by weight passing the 0.075 mm sieve is typically greater than 8 percent. Asphalt contents range from 6 to 7.5 percent by weight of total mix. Fiber, either cellulose or mineral, is generally added to prevent draindown of the binder during construction. SMA has been used extensively on airfields in both China and Norway. Additionally, airfields have been constructed using SMA in Australia, Belgium, Germany, Italy, Mexico, and the United States (U.S.). Additional details on specifications and individual projects are provided in reference. The U.S. Air Force constructed SMA runways in Germany and Italy.

TI - Adaptation of the French Rational Road Design Procedure to Airfield Pavement: the Alize-Airfield Software
PY - 2010
SP - 12p
AB - Alize-Lcpc is the reference software for roads and motorways pavement design in France since more than thirty years. It is a rational method, based on the computation of the resilient stresses and strains in roadways by the classical multi-layer elastic linear model. The design is carried out by comparing these calculated values in all the layers, to the admissible stresses and/or strains values which are evaluated according to the fatigue characteristics of the materials (bounded materials) or their rutting behavior due to plasticization (untreated materials and soils), taking into account the cumulative traffic specified for the pavement. In France, the adaptation of the road design approach to airport pavement is now in progress, leading to the development of a specific version of Alize-Lcpc software dedicated to the design of both flexible and rigid airport pavements. This paper firstly sums up the basis of the French rational pavement approach. It describes the possibilities of the new software, which are illustrated by an example of thickness design for a flexible pavement.

TI - Use of the Superpave Gyratory Compactor as a Predictor of Field Performance of Unbound
Material
PY - 2010
SP - 10p
AB - With continuous and repeated loading of runways and the introduction of larger planes, such as the Boeing-747 and Airbus A380, which weighs approximately 1.3 million pounds, a runway’s ability to resist rutting becomes even more critical. The Federal Aviation Administration (FAA) has been testing airport pavements under heavy aircraft loading with a wander pattern at the National Airport Pavement Test Facility (NAPTF) in order to improve airport pavement design for these heavy planes. The loads and the load wander of these large aircrafts have a dramatic effect on the stability and strength of the unbound aggregate layers because it causes constant particle rearrangement and compaction. In earlier testing cycles of the pavement systems, the subbase layer compacted excessively past the maximum Modified Proctor Density (ASTM D1557) during the simulated trafficking. The densification of this material caused the pavement system to rut. In order to monitor the performance of the runway, stress, strain, deflection, temperature, and other environmental gauges have been placed in the various layers of the pavement. Another problem that has been encountered during the previous construction cycles is moisture migration to the subgrade layer. Moisture migration causes a shear slip plane between the subbase and subgrade layer. The shear failure can increase the rate of deformation in the runway pavement. This study is focused on studying the compaction characteristics of the subbase material during aircraft trafficking using a combination of laboratory tests and field data.

TI - Backcalculation of Airfield Pavement Structures Based on Wave Propagation Theory
PY - 2010
SP - 17p
AB - Nondestructive testing equipment called FWD (Falling Weight Deflectometer) has been widely utilized for structural evaluation of pavement. This paper presents backcalculation of multilayered pavement layer parameters from FWD tests by using dynamic backcalculation software which authors have recently developed. The theoretical solution for a system of axisymmetric wave propagation equations was developed using Hankel transform in radial direction and Fast Fourier Transform in time domain and was implemented into this backcalculation software. This software is called Wave_BALM (Wave propagation based Back Analysis for Layer Moduli). The viscoelastic model used herein is called the Voigt solid (or Kelvin solid). The validity of this software was examined by using FWD time history data of airfield pavement provided by Federal Aviation Administration (FAA). Reliability of the results was confirmed by the following observations, 1) Backcalculation was conducted by using fifty sets of randomly generated seed values and the variation of the results was found small. 2) Excellent agreement between computed and measured deflections is confirmed.

PY - 2010
SP - 23p
AB - In the United States (US), FAARFIELD is now the new standard Federal Aviation Administration (FAA) design software for airfield pavements. In France, the Alizé-Airfield pavement program, developed by the Laboratoire Central des Ponts et Chaussées (LCPC) under a cooperative agreement with the Service Technique de l’Aviation Civile (STAC), is intended to become the reference design software. A similar rational approach to design is used in these two programs. It consists in comparing computed strains induced by traffic loads at critical levels of the designed structure to allowable strains. This paper deals with the comparison of US and French procedures for the design of flexible airfield pavements. It is aimed at describing the specifics of each of the two computer programs (e.g., model hypotheses, probability considerations, use of conservative parameters). A sensitivity study is conducted so as to quantify the change in output data with respect to the change in input parameters in both software programs. The versions used for comparison are FAARFIELD version 1.302 and Alizé-Airfield pavement 4.1.0. This parametric study concerns the influence of various input parameters (subgrade and asphalt moduli, gross weight, number of passes, layer thicknesses) on flexible thickness design for both isolated aircraft and traffic mixes, and considering both asphalt and subgrade failure criteria. A comparison of computed mechanical values obtained from FAARFIELD output files and Alizé-Airfield pavement charts is also presented.

PY - 2010
SP - 13p
AB - Criteria for overload evaluation of airport pavements are contained in International Civil Aviation Organization (ICAO) documents Annex 14, Attachment A and the Aerodrome Design Manual Part 3, and are stated in terms of the amount the ACN of an overload airplane can exceed the listed PCN of the pavement. But most modern airport pavement design procedures define the level of pavement deterioration in terms of cumulative damage factor (CDF). A mathematical relationship between an increment of ACN and an increment of CDF is derived so that overload operations evaluated by a CDF-based design procedure can be compared directly with the ICAO criteria. The relationship states that, if the allowable value of the ACN of an overload aircraft relative to the PCN of the pavement is taken to be given by, for example, a ratio of 1.1, then this represents an allowable change in CDF of approximately 0.5 due to the addition of an overload aircraft relative to the design condition of CDF = 1. The numerical value of the ratio of change of CDF to change of ACN varies with the sensitivity of the CDF-based design procedure to changes in airplane loading. The relationship can be calibrated for the CDF-based design procedure if desired.

PY - 2010
SP - 16p
AB - Heavy Weight Deflectometer (HWD) is the international reference device to assess the bearing capacity of airport pavements. Usual processing methods are based on static elastic models and backcalculations from the pseudo-static deflection bowls. These bowls are reconstituted from the deflection peak values measured on each geophone. These methods have shown their limits. This is the reason why interest for dynamic methods has been growing for a few years. The French civil Aviation technical Centre (STAC) is developing a finite element dynamical model taking into account the whole force signal applied on the load plate. That makes it possible to model the impact of the falling weight on the structure and the resulting deformations. Dynamic backcalculations allow determining the elastic modulus and damping in the pavement materials. The fitting includes the entire temporal signal of each geophone. This paper describes the developed theoretical model and presents a full-scale experiment performed on the STAC’s flexible testing facility in order to assess its appropriateness. Results of dynamical backcalculation are compared to pseudo-static backcalculation results (modulus of each material) and to experimental data obtained from laboratory tests performed on materials (modulus and damping factor). This paper includes three parts: (1) First, description of the experiment. (2) Second, presentation of the theoretical model and backcalculation procedure. (3) Third, comparison with pseudo-static results and in-situ validation.

TI - Development of Criteria for Using the Superpave Gyratory Compactor to Design Airport Pavement Mixtures
PY - 2010
SP - 16p
AB - It is important that the Superpave asphalt mix design method be adopted as an option for airfield pavements. The design of asphalt mixtures for airfields has been accomplished using the Marshall method since the 1940’s. The Superpave design method was developed and adopted by state department of Transportation's (DOTs) beginning in the mid 1990’s and, currently, most transportation departments have adopted this concept. Since most of the paving work by the asphalt industry is funded by state DOTs and private work (which typically use DOT criteria), it is becoming more difficult to find laboratories and contractors that continue to use the Marshall method. This study evaluated the number of gyrations for a number of mixtures required to provide a density equal to 75 blows with the Marshall hammer. Since the 75 blow Marshall mixture had performed well in the past it was believed that providing a density with the gyratory compactor equal to that obtained with Marshall compaction would be a good way to adopt Superpave and still have confidence of good performance. This paper describes the details of the study and provides a recommended number of gyrations with the Superpave gyratory compactor to provide a mixture that will perform similar to 75 blow Marshall mixture.

TI - Report to Congress: National Plan of Integrated Airport Systems (NPIAS), 2011-2015
PY - 2010
SP - 100p
AB - The National Plan of Integrated Airport Systems (NPIAS) for Fiscal Years (FY) 2011 to 2015 is submitted to Congress in accordance with Section 47103 of Title 49 of the United States Code. A national airport plan has been prepared at regular intervals since the mid-1940s. The plan identifies 3,380 public-use airports (3,332 existing and 48 proposed) that are significant to national air transportation and, therefore, eligible to receive grants under the Federal Aviation Administration (FAA) Airport Improvement Program (AIP). The development data contained in this report were largely compiled in 2009. The report estimates that over the next 5 years, there will be $52.2 billion of AIP eligible infrastructure development for all segments of civil aviation. This is an increase of 5 percent ($2.5 billion) over the last report issued 2 years ago. This report reflects an increase in development estimates for all categories of airports, except large hubs and new airports which are predicting slight decreases in AIP eligible development over the next 5 years. Airport capital development needs are driven by traffic growth resulting in the need to expand facilities, rehabilitation or reconstruction of infrastructure due to use and age of facilities, and changing aircraft technology requiring airports to update or replace equipment and infrastructure. The NPIAS is used by FAA in administering the AIP. It supports the goals identified in the FAA Flight Plan for safety and capacity by identifying airports and airport improvements that will help achieve those goals. Fifty-seven percent of the development is intended to rehabilitate existing infrastructure and keep airports up to standards for the aircraft that use them. Forty-three percent of the development in the report is intended to accommodate growth in travel, including more passengers, cargo and activity, and larger aircraft. This report includes a section on the condition and performance of the national airport system, highlighting six topics: safety, capacity, pavement condition, financial performance, surface accessibility, and environment. The findings are favorable indicating that the system is safe, convenient, well maintained, and largely supported by nonfederal revenue (rents, fees, and taxes paid by users).

TI - FAA Aerospace Forecast, Fiscal Years 2010-2030
PY - 2010
SP - 106p
AB - This years forecast confirms what we already know: Aviation is a business subject to highly volatile and unpredictable external influences. Whether it is the economy, the global political climate or environmental concerns, our industry is affected at every level. The good news is that aviation has shown time and time again that it can adapt and meet those challenges while continuing to provide safe, efficient transportation. This years forecast anticipates that these challenges will remain for at least 20 more years. But it also shows our confidence this industry will not only face these challenges head on, but will thrive. Aviation has been especially hard hit by the turbulence that has rocked our economy. As the economy dipped, airline demand fell sharply. Airlines have tightened their belts, passengers have modified their traveling habits, and our airports have had to adapt. But, economic growth will return along with passengers and increasing operations. We expect to see changes in the industry as it rebounds over the next several years, with international markets growing faster than domestic markets, and large airports growing faster than smaller ones. We also expect the trend toward larger regional jets to continue while most of the smaller regional jets will be retired from the fleet. For the remainder of 2010, we expect that last years trends will continue before the industry turns the corner. But we do expect growth in the longer-term. For the short-term, we will continue to see declines in both domestic and international capacity as carriers respond to the impacts of the economic downturn. The airlines will continue to make adjustments to fleets and operations to match changing demand.

TI - Answering the Call to Action on Airline Safety and Pilot Training
PY - 2010
SP - 201p
AB - The most important job of the U.S. Department of Transportation (DOT) and the Federal Aviation Administration (FAA) is to protect the safety of the traveling public. The authors aim to achieve this goal through ensuring that operators provide effective and high quality training to flight crews and other personnel; identifying and implementing most effective practices; maintaining and improving critical infrastructure; ensuring compliance with laws and regulations; developing new laws and regulations when appropriate; and working collaboratively with all interested parties. On February 12, 2009, a Colgan Air Bombardier Dash-8 Q400, operating as Continental Connection Flight 3407, crashed while on approach to Buffalo, New York. The National Transportation Safety Board (NTSB) conducted a public hearing on this accident from May 12-14, 2009. During that hearing and subsequent congressional hearings on June 10 and June 11, 2009, several issues came to light regarding pilot training and qualifications, flight crew fatigue, and consistency of safety standards between operators.

TI - Quick Response for Special Needs. Task 15. Aviation-Industry Issue Familiarization and Training for Part-time Airport Policymakers
AB - Few airports have adequate budgets with which to train the part-time policymaking leadership and key policy stakeholders on issues that affect airport policy decisions. Many airports are unable send part-time commissioners, board members, new policy leaders, or other policy-related stakeholders to conferences or seminars to learn and discuss the regulatory or national-political framework within which airports must operate. The Federal Aviation Administration (FAA), responsible for providing regulatory oversight for all airports, cannot interpret all nuances of their regulations to fit individual airport governance, purpose, or motivation models. It is understood that part-time airport policy leadership may not need to know much of this information to the degree of those who are working full-time within the terminal or airfield environment, on a technical or managerial basis. However, an overview of policy issues affecting airport administrative and operational decisions would provide airport policy leaders, stakeholders, and policy-related decision-makers a common framework to understand administrative and operational necessity, and thereby make better informed policy decisions. The target audience for this project would be airport executives and their part-time policy leaders, and key policy-making stakeholders. The project will include a review of current Airport Cooperative Research Program (ACRP) research, current literature, and industry practices related to airport-policy issues that are typically discussed with members of airport boards, part-time commissioners, policy-reviewing advisory committees, city councils, city managers, and other key participants in airport policy discussions. The research team will survey airports, interview FAA Airport District Office managers, and key industry associations. The project will assess all collected material and produce a concise summary of key policy issues (A Primer), as well as (stand-alone) recommendations of best practices for conveying information to the part-time policy makers, and recommend an agenda or syllabus for presenting key policy issues.

TI - Airport Leadership Development Program
AB - Future airport leaders require a deeper understanding of current issues and critical concerns as seen from the top of an airport organization. There are few low-risk settings where airport executives can exercise self-evaluation of leadership and decision-making skills with a group of their peers and mentors, and further develop the business acumen needed to direct public- and private-sector organizations in the airport industry. Airport leadership development programs exist in the industry but many have broader goals or present fundamental knowledge to entry-level executives. Research is needed to assist existing and future airport leaders to assess, obtain, and refine their individual leadership skills. Such programs exist in other industries and participants frequently derive long-lasting resource relationships from contact with other participants and instructors that will benefit continued growth. Moreover, such experiences and the skills that are developed are often portable throughout the industry. The objective of this research is to design, develop, pilot-test, and evaluate a complete airport leadership development program that can be used by others to assist existing and future airport leaders assess, obtain, and refine airport-industry leadership skills.

TI - Legal Aspects of Airport Programs. Topic 3-06. An Index and Digest of Decisions in LRD 1
AB - The Airport Cooperative Research Program (ARCP+ Legal Research Digest 1, Compilation of Airport Law Resources (January 2008) ("Digest 1") provides a comprehensive listing of airport-related legal resources, including judicial decisions, government publication, scholarly journals and other periodicals. The listing of judicial decisions is extensive and sorted by subject area. The indexing of judicial decisions in this manner makes the Compilation a useful tool for airport management and airport lawyers. However, people using the journal must still review an individual decision listed to determine the holding and its relevance to a particular legal issue that they face. Airport lawyers and airport management would benefit if they had access to single source document that not only listed judicial decisions relating to a particular legal issue but that also provided a summary of relevant holdings and a link to the source document itself. ACRP Research Digest 4, Compilation of Department of Transportation (DOT) and Federal Aviation Administration (FAA) Airport Legal Determinations and Opinion Letters Through December 31, 2007 (2008) ("Digest 4") provides an index similar to Digest 1, as well as summaries and links to source documents for DOT and FAA administrative decisions, determinations and legal opinions. A similar compilation of judicial decisions (with summaries and links to source documents) would complement the information contained in Digest 4, by providing comparable information about adjudications that did not involve Federal administrative determinations and about subsequent judicial determinations on administrative decisions that were challenged in court. The objective of this research project is to make these judicial decisions readily and inexpensively available to airport attorneys, the public and other researchers. Ideally, the product of this research, if all phases are implemented, would be a web-based searchable database containing the full text of each document as well as a short summary of the outcome. The database should allow searches by topic, court, and airport involved. The final research report should be a legal research digest similar in form, organization and content to Digest 4. Where applicable, the summary should identify by case name the administrative decision being reviewed. The summary should be in sufficient detail to serve as a research guide addressing all major holdings.

TI - Voice Over Internet Protocol: Speech Intelligibility Assessment
PY - 2009/12//Technical Note
SP - 36p
AB - In this study, the authors examined the speech intelligibility of five codecs and parameter settings to determine their suitability for Air Traffic Control use. These codecs (g711r64, g726r32, g729r8, g723r53, and g726r16) convert analog communications to digital communications. Standard intelligibility tests were used − the Modified Rhyme Test (MRT) and the Message Completion Task (MCT) − to examine intelligibility differences. For the MRT, codec type had an effect on intelligibility. Performance in an uncompressed audio condition was the best, followed by codecs g711r64 and g726r32, then g729r8, and then g723r53 and g726r16, respectively. Reaction times were consistent with the performance data, with the better performing codecs having shorter reaction times. Subjective intelligibility and acceptability ratings matched the performance and reaction time data. For the MCT, the intelligibility and acceptability ratings for all codecs were high, but no clear pattern was found in the performance data. The authors recommend that the National Airspace System Voice Switch (NVS) program further evaluate the three best performing codecs, g711r64, g726r32, and g729r8. These codecs delivered the best performance, the shortest reaction times, and the most positive feedback. It is also recommended that the NVS Program Office investigate the effect of channel noise, ambient noise, and level of network utilization on the intelligibility of different codecs.

TI - Evaluation of Human Performance While Wearing Respirators
PY - 2009/12//Technical Report
SP - 56p
AB - The goal of this study was to assess the feasibility of respirator use in Air Traffic Control and Technical Operations. The authors evaluated several models of Powered Air Purifying Respirators (PAPRs) and N95 respirators for usability, effects on human performance, and effects on the wearer’s well-being. The authors found that binoculars could not be used with any of the PAPRs. Wearing a PAPR affected communication, but the characteristics of the respirator, especially the sound level and frequency spectrum of the noise, played a significant role in determining the extent of the effect and the subjective experience of wearing it. The accuracy levels of face-to-face communication were below those that were considered to be minimally acceptable. For the N95 respirators, we found negative effects on face-to-face communication and observed obstructiveness during simulated maintenance.

AB - Civil aviation has become a vital component of todays lifestyle and of modern economic life. Just as Thomas Friedman asserts that cheap and ubiquitous telecommunications have lowered impediments to international competition and innovation, the airline industry has shattered barriers of distance that once limited many global economic transactions. More and more households and businesses have become reliant on the advantages and cost effectiveness of air transportation. Like the Internet and new laborsaving technologies, the growth and maturation of the aviation industry, and civil air transport in particular, is truly a modern marvel. Even during these turbulent economic times, aviation remains a unique link for commerce that contributes to the revitalization of the economy.

TI - Flight Attendant Fatigue, Part I: National Duty, Rest, and Fatigue Survey
PY - 2009/12//Final Report
SP - 28p
AB - Today’s aviation industry is a 24/7 operation that produces a variety of challenges for cabin crew members including extended duty periods, highly variable schedules, frequent time zone changes, and increased passenger loads. While these operational requirements may be necessary, they are far from ideal with respect to the human body’s biological rhythms for managing sleep and alertness. In fact, acute sleep loss, sustained periods of wakefulness, and circadian factors resulting from this form of misalignment all contribute to fatigue and fatigue-related mishaps (Caldwell, 2005; Rosekind et al., 1996). This survey study was conducted to identify the specific operational factors that may contribute to fatigue in cabin crew operations. A retrospective survey was disseminated to flight attendants representing 30 operators (regional = 17, low-cost = 7, and network = 6). The survey addressed 7 main topics: work background, workload and duty time, sleep, health, fatigue, work environment, and general demographics. Participants were 9,180 cabin crewmembers who voluntarily and anonymously completed the survey and met the criteria to be included in the report (i.e., active flight attendant that had flown the previous bid period with their current airline). This report outlines the results of this survey and provides specific recommendations regarding fatigue issues in cabin crew operations.

PY - 2009/12//Final Report
SP - 37p
AB - A study was conducted in the mid-1990s to determine the level of participation of airports and other aviation safety stakeholders in the Federal Aviation Administration voluntary wildlife strike reporting system. A statistical analysis of reported strikes resulted in findings that only a certain percentage of wildlife strikes were actually being reported. According to data collected since 1990, the number of reported strikes has increased. Researchers are certain that several factors have contributed to that increase, including broader participation in the reporting process, increased number of hazardous species, a steady increase in the number of aircraft in the sky, and changes in reporting statistics. These factors were recently verified by Part 1 of a two-part study into the reporting trends titled Wildlife Strike Reporting, Part 1, Trends 1990-2008. This report represents Part 2 of that study. The objectives of Part 2 were to (1) summarize trends in persons and other entities that report wildlife strikes and in methods used to report or obtain this strike information, (2) identify sources of data presently not used that might supplement the number of strikes captured, and (3) provide recommendations for enhancing the reporting of strikes or entry of strike information collected in other data sources to correct deficiencies.

PY - 2009/12//Final Report
SP - 25p
AB - The purpose of this project was to evaluate how smoke detection times are affected when the same quantity of smoke is released in either an empty or fully loaded cargo compartment. It also evaluated the effect on smoke detection times from active cargo containers that produce additional airflow patterns. Active containers are equipped with climate control systems that maintain the containers temperature and humidity for the duration of the flight. Tests were conducted in the main deck cargo compartment of a Boeing 727 and in the aft, below-floor cargo compartment of a B-747SP. Although there was some variability in the test results, in general, the smoke detectors alarmed quicker in loaded compartments than in empty compartments. In addition, the operation of the active cargo containers did not have a consistent influence on smoke detection times for the airflow conditions tested.

A statistical analysis of reported strikes resulted in findings that only a certain percentage of wildlife strikes were actually being reported. According to data collected since 1990, the number of reported strikes has increased. Researchers are certain that several factors have contributed to that increase, including broader participation in the reporting process, increased numbers of hazardous species, a steady increase in air traffic, and a change in reporting statistics. The primary objective of this analysis was to examine the trends in strike reporting from 1990-2008 to determine if the percentage of strikes reported to the FAA for inclusion in the National Wildlife Strike Database is increasing. A second objective was to document trends in the percent of strikes reported to the FAA that can identify the species of the wildlife struck, which is the most critical piece of data in a strike report. Based on the findings of the first two objectives, a third objective was to assess if the data presently collected under a voluntary system are adequate for understanding the problem of wildlife strikes in the United States, or if additional measures, such as mandatory strike reporting, should be taken. This report is the first of a two-part study focused on the subject of reporting wildlife strikes with civil aircraft in the U.S. Part 1 examines current strike reporting trends to determine if the current voluntary system is providing a sufficient quantity of data to support an accurate, statistical understanding of the national wildlife strike issue. Part 2 focuses on determining if changes are needed in the way wildlife strike data are collected by the FAA, and in particular if a mandatory reporting system needs to be implemented.

TI - Online Course and Regional Laboratory Development in Composite Maintenance Education, Including Training Repair Manual
PY - 2009/12
SP - 89p
AB - The major objective of this study was to develop and assess the feasibility of teaching an online class, combined with a regional laboratory that is consistent with industry training standards published as part of a Cooperative Agreement in a Federal Aviation Administration report and Commercial Aircraft composite Repair Committee SAE Aerospace Information Report document. These standards consist of terminal course objectives and teaching points. This development represented an application of online teaching methodologies, commonly used in the social sciences such as business management and mathematics, into engineering technology. Engineering courses have not typically used the latest teaching technologies, and this approach will provide specific advantages not commonly achieved in traditional classroom frameworks. In addition, a training repair manual was developed as an important training tool for the laboratory portion of the class to expose students to the importance and use of authoritative documentation in the conduct of composite materials maintenance. Advantages of the online course approach were demonstrated as follows: (1) Greatly reduced education costs due to limited travel expenses; (2) Ability for the student to fit classroom activities within busy schedules due to the asynchronous nature of online learning; (3) Independence of global time zone effects; (4) Ability to involve experts in the composites' field to participate to a wide student audience, providing access to considerable knowledge and experience which is not as accessible in the traditional classroom; and (5) Broader student participation, mandated by the online methodology. Three major sections of the course were addressed, annotated by the number of students completing each in the prototype class: (1) a prerequisite course to bring students to a common level of understanding before taking the awareness course, (2) the awareness course, which represents the industry standard developed in earlier phases of this Cooperative Agreement, and (3) a hands-on laboratory.

TI - Evaluation of the Effects of Hydrogen Peroxide on Common Aviation Structural Materials
PY - 2009/12//Final Report
SP - 24p
AB - Infected passengers can unintentionally contaminate the interior of aircraft; deliberate biological contamination from criminals and international adversaries is also possible. Previous work has provided information regarding the delivery mechanism and capability of STERIS Corporation's Vaporized Hydrogen Peroxide (VHP * ) technology as a decontaminant/disinfectant/sanitizer for transportation vehicles like aircraft, buses, subway trains, ambulances, etc. The present report documents a materials compatibility evaluation of the effects of hydrogen peroxide exposure on the physical and mechanical properties of the following commercial grade structural materials: 2024-T351, 2024-T6 and 7075-T6 aluminum, 304 stainless steel, carbon fiber/epoxy composites and glass fiber/epoxy composites, including FR4 laminate materials widely used for printed circuit boards. Measurements of changes in sample weights due to absorption, oxidation, or corrosion were made as were evaluations of changes in tensile and flexural mechanical properties. The tensile properties of samples of the metallic samples were unaffected by exposures to either vapor phase or 35% liquid phase hydrogen peroxide. In addition, the carbon fiber/epoxy, glass fiber/carbon fiber epoxy, and the FR4 printed circuit board materials exhibited no significant changes in flexural strength or strain at peak load after 10 VHP exposures. However, some mechanical degradation in the composite samples was observed after 168 hour exposure to 35% liquid hydrogen peroxide. It is recommended that condensation be avoided during application of vapor phase hydrogen peroxide. *VHP is a registered trademark of the STERIS Corporation, Mentor, OH.

TI - Flight Attendant Fatigue, Part IV: Analysis of Incident Reports
PY - 2009/12//Final Report
SP - 40p
AB - Voluntary safety reporting is one method by which aviation personnel can report safety issues to their airline and the Federal Aviation Administration. The Aviation Safety Reporting System (ASRS) is a program managed by the National Aeronautics & Space Administration (NASA) Ames Research Center. This study reviewed flight attendant reports from the ASRS database to identify the frequency of fatigue reports and the conditions under which fatigue occurred. During June 2008, 2,628 cabin crew reports were downloaded from the NASA ASRS Web site for reports made between January 1990 and December 2007. CAMI researchers reviewed each full-form report narrative for possible contributors to fatigue, or indicators of fatigue. Although the overall number of flight attendant ASRS reports for which full-form coding was completed has decreased over the last 3 years, both total flight attendant reporting and the number of full-form narratives related to fatigue have increased substantially. This voluntary data allows regulators and operators to discover potential problems in the aviation industry before they result in a mishap. The results of this review indicate that flight attendant fatigue may be occurring more frequently and warrant more attention.

TI - Legal Aspects of Airport Programs. Topic 3-05. Analyses of State and Federal Regulations that May Impede State Initiatives to Reduce an Airport's Carbon Footprint
AB - There is a growing movement among State and Federal agencies to focus on transportation systems, including airports, in the ongoing efforts to reduce carbon emissions. In California, for example, the Governor signed Assembly Bill 32 (AB32), the Global Warming Solutions Act of 2006. AB 32 calls for a reduction by 2020, of greenhouse gas emissions (GHG emissions) in the State of California to levels recorded in 1990. The San Diego Airport's Master Plan became the subject of focus by the California Attorney General who sought to have the Airport's Master Plan environmental review address the impact of the expansion plan on GHG emissions, pursuant to its obligations under AB32. The Attorney General and the San Diego Airport entered into an MOU that specifies the measures the Airport will take to reduce GHG emissions. However, under federal law, only the U.S. Environmental Protection Agency and the Federal Aviation Administration have authority to regulate aircraft emissions. It can be expected that ongoing state and federal mandates to reduce GHG emissions will have an impact on Airports nationwide as the EPA and States seek ways to accomplish GHG reductions. It would be helpful to airport lawyers to have a digest of airport initiatives and state and federal laws and regulations that govern an airport's ability to implement GHG reduction efforts consistent with their concurrent obligation to permit aviation activity as mandated by federal statutes, regulations, and the FAA. The intent of this ACRP Legal Topic is to survey and categorize airport efforts to reduce GHG emissions and to summarize state and federal laws that affect an airport's ability to implement GHG reductions. A compilation of carbon reduction initiatives at airports which categorize the efforts in terms of distinguishing between green building requirements and other building code directives (for example, enegy efficiency initiatives, lighting and HVAC efficiency improvements, and use of solar energy), and efforts directed at reducing aircraft GHG emissions (for example by use of preconditioned air units and aircraft tugs, or limits on engine idling). The Consultant shall survey existing literature, research state and federal statutes, case law, and survey airport proprietors, and other knowledgeable persons in order to identify initiatives and GHG reduction trends as described above. Of particular interest should be state legislation which specifically requires airport GHG impacts to be addressed in any expansion plan environmental reviews. The report should synthesize the literature, statutes, regulations, and case law gathered by the Consultant's research efforts. The primary data collected through surveys and interviews should be tabulated and presented to supplement the legal synthesis.

TI - Flight Attendant Fatigue, Part V: A Comparative Study of International Flight Attendant Fatigue Regulations and Collective Bargaining Agreements
PY - 2009/11//Final Report
SP - 19p
AB - In 2008, Congress directed the Civil Aerospace Medical Institute (CAMI) to conduct follow-on studies of six recommendation areas noted in an integrated report by the National Aeronautics and Space Administration (NASA) and CAMI regarding flight attendant fatigue. The report concluded that some degree of fatigue-related performance affects were likely under current prescriptive rules. Internationally, fatigue risk is managed almost solely through prescriptive rules based on the maximum hours of work and minimum hours of rest. Traditional prescriptive rules, however, have limited applications to round-the-clock operations, often excluding fatigue-contributing factors such as time zone transitions, layover and recovery, time of day, and circadian rhythms (Cabon et al, 2009). Prescriptive rules directly affect crew scheduling and are critical to operator viability; however, due to economic recession, operators are routinely scheduling up to the regulation limits, which could result in an increased likelihood of fatigue and fatigue-related mishaps (Nesthus, Schroeder, Connors, et al., 2007). In the present study, the authors obtained regulations (n=38) and collective bargaining agreements (CBA) (n=13) regarding flight attendant duty time and rest from International Civil Aviation Organization (ICAO) member states using several resources: Civil Aviation Authority Web sites, an international cabin safety symposium, Web-based ICAO information exchange, and FAA international field offices and aviation safety inspectors. They analyzed each regulation and CBA to identify duty time and rest rules related to working hour limits, sleep and rest requirements, circadian rhythms, and other factors. When comparing the United States (U.S.) maximum hours of work and minimum hours of rest with other countries, the authors concluded that U.S. prescriptive rules are among the least restrictive, representing a greater than typical risk for fatigue related incidents. They recommend the U.S. establish a sanctioned fatigue workgroup of subject matter experts, aviation stakeholders, medical and research scientists, and aviation Safety Management System experts to evaluate current regulations and develop an adaptive fatigue mitigation safety system combining scientific principles and knowledge with operational support.

TI - Testing MiniSTR Primers for Addition to a PCR-Based Forensic Specimen
Identification Protocol
PY - 2009/11//Final Report
SP - 10p
AB - An assay has been developed for polymerase chain reaction (PCR)-based human identity testing using the Federal Bureau of Investigation’s human Combined DNA Identity System (CODIS) primers. Recent forensic literature has identified difficulties using these primers due to amplicon size and the degraded nature of DNA from forensic samples. Primers termed mini Short-Tandem Repeat (STR) primers targeted to the same loci as the CODIS primers but which have smaller amplicons have been developed. Two of the three miniSTR primer pairs examined with our established assay were successfully tested with forensic DNA. This allowed the substitution of new primers for detection of a locus, D16S539, which was poorly defined in our assay and the addition of a primer pair for a locus, FGA, not previously included. The replacement of the D16S539 CODIS primers with the miniSTR primers will provide more accurate results for this locus. The addition of the FGA mini STR primers to the core set of tested loci will increase the overall power of discrimination of our assay.

TI - Federal Aviation Administration Aging Mechanical Systems Program: Emergency Evacuation System
PY - 2009/11//Final Report
SP - 92p
AB - The Federal Aviation Administration (FAA) was tasked to determine if material degradation in emergency evacuation systems (EES) was a major mode of failure for the air operators. The FAA Aging Mechanical Systems Program was established to examine the current reported problems with EES, to investigate the adequacy of the current testing standard, and to identify potential long-term material problems. The current reported problems with EES, EES testing, and material-related issues were evaluated. EES-related reports and incidents, covering 1 January 1999 to 31 August 2006, were categorized and summarized into a database. Mechanical attachment problems were the primary source of the EES reported incidents, regardless of the aircraft model. This issue must be addressed by the aircraft manufacturers, since the EES manufacturers do not have design responsibility for this portion of the EES system, except for the Boeing 777. Material-related EES reports were mainly due to corrosion, failure, or wearing of mechanical attachment components. Reported slide abrasions, seam tears, punctures, or holes were probably due to improper handling during assembly or improper packing. A small and limited number of slide entries could be associated with material degradation or seam separation. The requirements for EES qualification tests need to be clarified. Some airlines report an inadvertent deployment as a successful test meeting the requirement of testing one slide per door per aircraft type in their fleet every 3 years. While an inadvertent deployment may serve as a go-no-go qualification test, it does not provide sufficient information regarding time of inflation or deflation. Southwest Airlines interpretation of Title 14 Code of Federal Regulations 121.703 (17) for a reportable Service Difficulty Report is distinctly different from the rest of the industry. It is recommended that the FAA review the requirements and provide guidance to the airlines and maintenance operations for the correct interpretation of this regulation.

TI - Workstation and Workplace Ergonomics at Federal Aviation Administration Operations Control Centers: Phase 1 - Evaluation of Ergonomic Issues
PY - 2009/10//Technical Report
SP - 56p
AB - The purpose of this study was to collect data on current workplace ergonomic conditions at Federal Aviation Administration Operations Control Centers. Ergonomic issues and associated work-related musculoskeletal disorders can arise due to a combination of factors including environmental conditions, workstation design, frequency and duration of tasks, and psychosocial considerations. In order to create a comprehensive picture of Operational Control Center ergonomics, researchers collected a range of data. Researchers collected data on the workplace environment, including temperature, lighting, and noise. They collected workstation data, measuring the dimensions and features of the desks and chairs and comparing them to standards. Researchers observed and recorded the frequency and duration of user activities during periods of typical work. Finally, they collected data through a questionnaire, which allowed the participants to provide feedback and ratings on their current level of discomfort and on various aspects of their work environment. The research team identified instances where measurements of the current workplace did not meet recommended standards, including temperature, lighting, and workstation adjustability. These deficiencies could result in increased ergonomic risk to the users, a concern that was reflected in the questionnaire results. Questionnaire responses also identified potential ergonomic issues beyond the physical workstation, including psychosocial and organizational factors. These issues and some potential solutions are discussed in detail in this report.

AB - Following the record-breaking flight delays of summer 2007, the Secretary of Transportation established the Aviation Rulemaking Committee (ARC) to identify ways to reduce delays and congestion at the New York (NY) area airports. The Federal Aviation Administration (FAA) has stated that NY delays impact the entire national airspace system due to those airports' high volume, complex traffic patterns, and airspace management problems. On December 13, 2007, the ARC issued its report highlighting 77 initiatives for improving aviation operations and infrastructure. This report presents the results of our review examining FAA's actions in response to the ARC's recommendations. The authors conducted this audit at the request of the Chairman of the House Subcommittee on Aviation, who expressed the Subcommittee's concern about the effectiveness of delay-reduction efforts at the NY airports. Our audit objective was to examine FAA's progress in implementing the 77 ARC initiatives.

We observed from archived radar data that while rarer than single-threat encounters, multiple threat encounters occur more frequently than originally expected. The multi-threat logic has not been analyzed in the past using encounter models. To generate multi-threat encounters, this report extends the statistical techniques used to develop pairwise correlated encounters. We generated and simulated a large number of multi-threat encounters using the TCAS logic imprlementad in Lincoln Laboratory's Collision Avoidance System Safety Assessment Tool.

TI - Modeling Wing Tank Flammability
PY - 2009/10//Final Report
SP - 116p
AB - An investigation into the fire safety of a wing fuel tank has been performed to aid in the effort to eliminate or reduce the possibility of a wing fuel tank explosion in a commercial aircraft. A computational model is built to predict the generation of flammable mixtures in the ullage of wing fuel tanks. The model predicts the flammability evolution within the tank based on in-flight conditions of a wing fuel tank. The model is validated through supporting experiments performed in an altitude chamber, the wind tunnel facility as well as data obtained from flight tests. The results from the experiments are compared to the computational results. Computational results from the altitude chamber follow the general trend of the experimental results, but produce them at a different flash point. This is due to the replenishment of species with lower flash point at the surface of the fuel which emulates the flash point of the entire fuel to be lower. Experimental results for the aluminum wing tests from the wind tunnel experiments are in good agreement with the computational results as well. A simpler model is developed from a program that calculates fuel air ratio within the ullage of fuel tanks in order to reduce the required number of inputs to the model. This model is applied to the data sets for the experiments performed in the altitude chamber and wind tunnel. For the tests conducted in the altitude chamber, the correlation estimates the hydrocarbon concentrations extremely well during ascent and descent. During the on-ground condition the estimation is good, but not as accurate as the ascent or descent conditions. For the tests conducted in the wind tunnel, the computational values follow the general trend of the experimental values, but the computational values estimates the total hydrocarbon concentration approximately 10% lower than the experimental value consistently. Flammability studies are also performed in order to track the effects of temperature, pressure, and oxygen concentration on the upper and lower flammability limits. For the temperature and pressure profiles considered in this work, it is found that the temperature and pressure effects on the flammability limits are minimal. In contrast, the oxygen concentration has a significant effect on the flammability limits of the vapor; the flammable region narrows with a decrease in oxygen concentration.

PY - 2009/10//Final Report
SP - 111p
AB - Exposure to carbon monoxide (CO), which is formed by the incomplete combustion of carbon-containing materials such as aviation fuels, is associated with headache, dizziness, fatigue, and at elevated doses, death. Exhaust system failures in general aviation (GA) aircraft can result in CO exposure. When this occurs in an aircraft, the end result could be an accident. This research on detection and prevention of CO exposure in GA aircraft addressed the following objectives: (1) to identify protocols to quickly alert users to the presence of excessive CO in the cabin and (2) to evaluate inspection methods and maintenance practices with respect to CO generation. These objectives were accomplished by review of (1) the National Transportation Safety Board database for CO-related incidents/accidents, (2) current CO detector technology, and (3) industry inspection and maintenance practices, Advisory Circulars, and FAA regulations with respect to GA exhaust systems.

TI - Flight Attendant Fatigue, Part VI: Fatigue Countermeasure Training and Potential Benefits
PY - 2009/10//Final Report
SP - 20p
AB - Today’s aviation industry is a 24/7 operation that produces a variety of challenges for cabin crew members, including extended duty periods, highly variable schedules, and frequent time zone changes. While these operational requirements may be necessary, they are far from ideal with respect to the human body’s biological rhythms for managing sleep and alertness. In fact, acute sleep loss, sustained periods of wakefulness, and circadian factors resulting from this form of misalignment are all contributors to fatigue and fatigue-related mishaps (Caldwell, 2005; Rosekind et al., 1996). The strategic management of fatigue is necessary for safety improvement throughout the industry. Employee educational programs regarding the dangers of fatigue, the causes of sleepiness, and the importance of proper sleep hygiene to improve sleep quality may be critical for effective fatigue management (Caldwell, 2005). This report outlines specific recommendations regarding fatigue countermeasures training and its potential benefits to flight attendant operations.

TI - Application of DNA Profiling in Resolving Aviation Forensic Toxicology Issues
PY - 2009/10//Final Report
SP - 18p
AB - Biological samples from the victims of aviation accidents are submitted to the Civil Aerospace Medical Institute (CAMI) for toxicological evaluation. Body components of aviation accident fatalities are often scattered, disintegrated, commingled, contaminated, and/or putrefied at accident scenes. These situations may impose difficulties in victim identification and tissue matching, thereby in the toxicological analysis of authentic samples and the interpretation of the associated analytical results. The use of DNA typing has been exemplified in the literature to resolve the sample misidentification issue. However, the prevalence of this type of issue in relation to aviation accident forensic toxicology has not been well-established. Therefore, the CAMI toxicology database was searched for the period of 1998−2008 for those accidents/cases wherein DNA profiling was performed. During this period, samples from 3523 accidents were received by CAMI. Of these, there were 3366 aviation accidents wherein at least one fatality had occurred. Biological samples from a total of 3319 pilots were received. Of these, 3275 were fatally injured. The 3319 pilots translated into the equivalent number of aviation accidents. Of the 3319 accidents, there were only 15 (≈ 0.5%) accidents wherein DNA profiling was performed on the biological samples. Six occupants (four fatalities and two injured victims) were involved in one accident and five (two fatalities and three injured victims) in another. Three fatalities occurred in three accidents each, two fatalities in eight accidents each, and one fatality in one accident. In one accident, there were two occupants with non-fatal injuries. DNA profiling was conducted upon the requests of families in two accidents, of accident investigators in three, and of pathologists in four. In six accidents, contradictory toxicological findings—such as selective presence of analytes in samples—led the CAMI laboratory to initiate DNA profiling. The requests made by families and investigators were primarily triggered by the inconsistency between the toxicological results and the history of the use of the drugs by the victims, while by the pathologists because of the commingling of samples. In three (20%) of the 15 accidents, at least one submitted sample was misidentified or mislabeled. The low number of the accident cases requiring DNA profiling suggests that the sample-submitting agencies take extensive precautionary measures to ensure that the origin of the submitted biological samples are correctly identified. Furthermore, the present study confirms that DNA typing can be used as a tool for establishing the authenticity of the aviation biosamples, thereby their associated toxicological conclusions.

TI - Recycling Strategies for the Airport Industry
AB - Recycling is a critical aspect of ongoing efforts at airports and airlines to reduce environmental impacts. As airports throughout the country continue to implement and expand recycling programs, consideration should be given to their compatibility with airline recycling programs and the potential for increased recycling of materials from aircraft. Identifying practices and opportunities to improve the types and amount of material recycled from onboard aircraft will serve to further both airlines' and airports' environmental sustainability objectives. Cost-effective recycling of materials from onboard aircraft presents many challenges. From an airline perspective, there are logistical challenges associated with collecting, separating, and storing materials onboard for removal and recycling on the ground. Likewise, airport recycling programs are complicated by varying state and local requirements, local recycling capabilities, airport infrastructure, waste hauling contracts, and airside safety concerns, among other factors. As a result of these complexities, airport recycling programs across the country can vary significantly. The objective of this research is to analyze current airport recycling programs to identify practices to improve the recycling of materials from onboard aircraft, including suggested improvements to increase the amount and type of materials that may be cost-effectively recycled. The research will include consultation with airport and airline environmental managers and research into innovative recycling practices. Given the increased focus on accounting for improved environmental performance, the research should also identify suggested methods to properly allocate credit and economic benefit for recycled materials among the entities engaged in recycling at an airport. The resulting product will be a reference guide for airports contemplating initiating or improving a recycling program that identifies specific measures that can be taken to improve the potential for increased recycling from onboard aircraft.

TI - Developing a Database-Driven Web Application for Benchmarking Airport Performance
AB - Benchmarking is the process of identifying best practices in a particular organization or industry and using measures to track performance against an organizational or industry level of quality or excellence. Benchmarks have various purposes. They can be used to measure progress within a particular organization or to compare performance among similar or competing organizations. At airports, benchmarks have frequently been used to measure financial and operational performance. Recently they have also been used to relate levels and types of commercial services with customer satisfaction. Five recognized basics of benchmarking are (1) deciding what and how to measure performance, (2) identifying and analyzing key performance metrics, (3) determining peers for performance comparisons, (4) refining performance goals, and (5) monitoring progress and communicating results to decision makers. Benchmarking is most valuable when used as a catalyst to increase performance to that of leading organizations, which have similar demographic, economic, or operational characteristics. For airports, such peer comparisons can help place performance into perspective and improve the understanding of airport performance.

TI - Photoluminescent Material Evaluation
PY - 2009/09
SP - 22p
AB - The fundamental principle of photoluminescent technology is the ability of the photoluminescent material to absorb and store ambient ultraviolet light energy from its surroundings and then emit the stored energy as visible light. Two particular photoluminescent pigments have been used in the development of marking systems: zinc sulfide and strontium aluminate. Both afford a pale, flat, yellow-green color when viewed in lighted conditions; in darkness, the zinc sulfide material glows with a more yellow-tinged light compared to the greener emission of the strontium aluminate. While neither of these pigments provide significant levels of illumination, these markers are used for low-location lighting and escape route marking systems onboard aircraft. As a result of these developments, manufacturers of the photoluminescent materials approached the Federal Aviation Administration (FAA) to allow these materials to be used for airport markings, reflectors, signs, and construction barricades as well. The manufacturers were asked to provide specific information about their products, such as suggested paint application thickness, area covered per gallon, useful light emission duration, serviceable life, and longevity/durability data. The luminance characteristics of the photoluminescent materials were evaluated at the FAA William J. Hughes Technical Center to assess their suitability in an airport environment. The initial illumination, duration of useful light, and emission decay rate of the test samples were measured at predetermined intervals during photometric and subjective visual tests.

TI - Safety Risk Analysis of Unmanned Aircraft Systems Integration Into the National Airspace System: Phase 1
PY - 2009/09//Final Report
SP - 84p
AB - This report describes the system-level development of a hazard taxonomy for Unmanned Aircraft Systems (UAS). The taxonomy is termed the Hazard Classification and Analysis System (HCAS) and was developed by researchers at Rutgers University through a cooperative agreement with the Federal Aviation Administration (FAA). It was particularly emphasized that this study should remain focused at the systems level and not become operational in perspective. The Rutgers Phase 1 approach is based on the FAA regulatory perspective (i.e., Title 14 Code of Federal Regulations chapters on Aircraft, Airmen, Certification/Airworthiness, Flight Operations, and others). Such an approach uniquely distinguishes the HCAS taxonomy from all other UAS hazard analyses being performed by the Department of Defense, the RTCA-Special Committee 203, etc. The Phase 1 research goal was to develop a generalized taxonomy of system-level UAS hazards that would have broad applicability across FAA part types. The intent was that this Phase 1 study would lead to general research recommendations and guidelines in high-level support of the FAA UAS Program Office. The report describes the developmental steps leading to the HCAS taxonomy.

PY - 2009/09//Final Report
SP - 24p
AB - A program to simulate the performance of aircraft composite material as uncontained engine fragment barriers has been initiated and supported by the Federal Aviation Administration (FAA). Computational constitutive models of the shields are an important part of that program. An important initial step in the FAA program was the determination of the lamina properties of a representation carbon-fiber composite panel. BMS 8-212 lamina properties for use in the computational modeling of aircraft shielding systems were determined in this study. The carbon-reinforced BMS 8-212 composite lay-ups that were tested were unidirectional, 0.351 inches thick (45-ply) flat panels. The mechanical responses of the flat panel unidirectional specimens were assumed to be representative of the behavior of the matrix-dominated compressive BMS 8-212 lamina responses in the transverse and normal directions. The rate sensitivity of the flat-panel specimens was determined for loading rates between 0.001 s-1 and 1000 s-1. In that regime, the transverse and normal failure stresses were found to increase by approximately 1.5.

PY - 2009/09//Final Report
SP - 63p
AB - At some airports, Engineered Material Arresting Systems (EMAS) are used in runway safety areas at to provide a mechanism for decelerating aircraft in the event of a runway overrun. The main component of an EMAS is energy-absorbing cellular concrete material that is relatively delicate. A system of sealants, coatings, and outer layers protect the cellular concrete from environmental conditions such as weather and jet blast. A research study was conducted to ascertain an EMASs durability in cold climates where temperatures cycle between freezing and thawing. Four series of tests were performed, including (1) thermal cycling on a large-scale EMAS bed, (2) temperature and humidity cycling on 1-cubic-foot EMAS samples, (3) adhesion tests on EMAS sealant materials, and (4) durability tests on the materials that comprise the top protective layer of EMAS blocks. The large-scale EMAS bed was thermally cycled from -20 degrees F to room temperature for 20 cycles over a 9-month period. Qualitative condition assessments were performed during the cycling, and quantitative post-cycling punch tests were performed and compared to the pre-cycling punch tests.

TI - Redeployment of the New York TDWR: Technical Analysis of Candidate Sites and Alternative Wind Shear Sensors
PY - 2009/09
SP - 106p
AB - The John F. Kennedy International Airport (JFK) and LaGuardia Airport (LGA) are protected from wind shear exposure by the New York Terminal Doppler Weather Radar (TDWR), which is currently located at Floyd Bennett Field, New York. Because of a September 1999 agreement between the Department of the Interior and the Department of Transportation, this location is required to be vacated not later than January 2023. Therefore, a study based on model simulation of wind shear detection probability was conducted to support future siting selection and alternative technologies. A total of 18 candidate sites were selected for the analysis, including leaving the radar where it is. (The FAA will explore the feasability of the latter alternative; it is included in this study only for technical analysis.) The 18 sites are: Six candidate sites that were identified in the initial New York TDWR site-survey studies in the 1990s (one of which is the current TDWR site), a site on Staten Island, two Manhattan skyscrapers, the current location of the WCBS Doppler weather radar in Twombly Landing, New Jersey, and eight local airports including JFK and LGA themselves. Results clearly show that for a single TDWR system, all six previously surveyed sites are suitable for future housing of the TDWR. Unfortunately, land acquisition of these sites will be at least as challenging as it was in the 1990s due to further urban development and likely negative reaction from neighboring residents. Evaluation results of the on-airport siting of the TDWR (either at JFK or at LGA) indicate that this option is feasible if data from the Newark TDWR are simultaneously used. This on-airport option would require software modification such as integration of data from the two radar systems and implementation of 'overHead' feature detection.

TI - Modular, Portable, and Reconfigurable Wireless Sensing System for the Aircraft Cabin
PY - 2009/09//Final Report
SP - 21p
AB - This paper describes the design and prototyping of a modular, portable, reconfigurable, and wireless multipurpose sensor system for monitoring and recording environmental conditions in aircraft cabins. The objective of this small, portable embedded sensing system is to record aircraft cabin conditions on flights of convenience to generate a large database for determination of normal conditions. By designing a sensor system that can be easily reconfigured for different needs (with the ability and flexibility to accommodate different/extra sensors), the system can be used to measure parameters that meet multiple research requirements. Through design considerations such as generalized signal interface and hierarchical code structure that can be easily reworked for new sensors, this sensor system has been developed for optimum usefulness in aircraft environment research. In the current setup, the system is configured with temperature, humidity, sound level, carbon dioxide, and pressure sensors. The system has been calibrated in the laboratory without the use of a pressure chamber. Data from six flights are presented in this report.

TI - An Experiment to Evaluate Transfer of Upset-Recovery Training Conducted Using Two Different Flight Simulation Devices
PY - 2009/09//Final Report
SP - 20p
AB - Air transport training programs provide simulator-based upset-recovery instruction for company pilots. However, no prior research demonstrates that such training transfers to an airplane in flight. The authors report on an FAA-funded research experiment to evaluate upset-recovery training transfer. Two groups of participants were given simulator-based training in upset-recovery, one in a high-end centrifuge-based device, the other using Microsoft Flight Simulator running on desktop computers. A third control group received no upset-recovery training at all. All three groups were then subjected to serious in-flight upsets in an aerobatic airplane. Pilots from both trained groups significantly outperformed control group pilots in upset-recovery maneuvering. However, performance differences between pilots from the two trained groups were less distinct. Moreover, pilot performance in both trained groups fell well short of the performance exhibited by pilots experienced in all attitude flight. Although the authors conducted flight testing in a general aviation airplane, their research has important implications for heavy aircraft upset-recovery trainers.

TI - Applying Intelligent Transportation Systems to Improve Airport Traveler Access Information
AB - Many airports have developed elaborate and often highly sophisticated programs for providing travelers with ground access information, but there is no common format for presenting this information to the public, either on airport websites or via other electronic media. As U.S. airports consider making new or expanding existing capital investments to improve public access, there is increasing interest in the potential for creating a consistent format for quickly and effectively presenting information on viable ground access travel options using Intelligent Transportation Systems (ITS) technology. In the broadest sense, ITS encompass a range of wireless and wired communications-based information and electronics technologies. Although many metropolitan areas are developing traveler information systems, few existing systems address ground access requirements specific to airport travelers. Airport travelers have become accustomed to attaining necessary information using technology. In addition, travelers to and from airports, both resident and non-resident, often need real-time information about parking availability, access delays, and alternative travel modes. Research is needed to provide uniform guidance to assist airports in providing pre-trip planning and real-time information in a consistent or similar format. The objectives of this research are to (1) describe opportunities for using Intelligent Transportation Systems (ITS) technology to help travelers simply, efficiently, and interactively evaluate their airport ground transportation options; and (2) prepare a guidebook for use by airport operators (in cooperation with transportation service providers) to develop and implement ITS solutions specific to their environment. The guidebook should encompass existing and emerging technologies for presenting useful information, addressing all forms of ground transportation available to travelers to and from the airport. The guidebook should (1) identify options for providing interactive pre-trip planning using real-time information on ground access services and facilities and (2) provide functional specifications for and a mock-up of a web-based or other technology-based information delivery system for trip planning, adaptable for use at a wide variety of airports with a reasonable degree of commonality. The guidebook should also include a CD containing a downloadable version of the mockups and an interactive demonstration using a suitable application platform. The ITS approach should consider how desired traveler information can be provided using a framework similar in content yet customizable by individual airports.

TI - Legal Aspects of Airport Programs. Topic 03-02. Compilation of State Aviation Authorizing Legislation
AB - Each state has enacted legislation creating and empowering governmental entities such as state agencies, municipalities, airport authorities, joint power organizations, etc. to plan, design, construct, operate, and protect public airports. As a result, there is a national patchwork of legislation pursuant to which these airports operate. There is also considerable diversity from state to state in the breadth and specificity of legislation empowering airport owners and operators. It would be useful for policy-makers, airport operators, and other practitioners to have available a convenient and synthesized resource of all states' airport-specific legislation. The objective of this research project is to compile, review and summarize in digest form, each state's airport-specific legislation, including, but not limited to, laws establishing, developing, operating, expanding, and funding airports. The compilation should be limited to legislation expressly applicable to public airports rather than legislation applicable to local governments generally. The report should also compare and contrast the legislation concerning specific categories of statutory powers and limitations, such as: (1) Zoning and land use; (2) Purchasing authority; (3) Commercial operations and permitted uses; (4) Ground transportation access; (5) Public access and use; (6) Funding & taxing authority; (7) Land acquisition and divestment (sale, lease or exchange); (8) Law enforcement; (9) Right to sue and be sued; and (10) Grant of immunities, including sovereign, antitrust, and tort immunities. The compilation should be sufficient to provide airport operators with a useful guide to the various state enacted approaches to specific subjects.

TI - Legal Aspects of Airport Programs. Topic 3-01. Fair Disclosure of Airport Impacts in Real Estate Transfers
AB - The purpose of fair disclosure laws is to provide prospective home buyers with sufficient information to make informed decisions about the purchase of property. Airport operators are particularly interested that home buyers obtain information about the noise and flight paths associated with airport operations before prospective buyers make decisions about purchasing property located near an airport. In too many cases property is purchased near airports without full disclosure of the nature of airport operations and thus the potential for purchaser remorse based on the lack of disclosure of airport noise and operations. In some cases, the adoption of fair disclosure laws that include the disclosure of the potential impacts of aviation operations has been impeded by the fear of some homeowners, local officials, and representatives of the real estate industry that such disclosure may provide an exaggerated impression of the significance of aviation related impacts and thereby impair property values. Proponents of such disclosure laws maintain that the real estate market takes account of any aviation related impacts regardless of fair disclosure laws. Still others argue that existing fair disclosure laws are adequate to address issues that arise regarding the disclosure of airport noise and operations in the area where a home is purchased. The intent of this ACRP Legal Topic is to survey existing fair disclosure laws among the states, determine if and how existing fair disclosure laws are meeting the need for a disclosure to prospective purchasers of airport-related conditions and operations, and to develop an annotated model fair disclosure law. The model fair disclosure law developed for this topic should be in a form that is appropriate for consideration by state legislatures and local governments. The Consultant shall survey existing literature, research state laws, case law, and survey airport proprietors, trade associations, and other knowledgeable persons in order to identify circumstances and occurrences involving the issues described above. Of particular interest should be legislation or case law which specifically requires the disclosure of airport noise and operations in the area where a home is located. The report should synthesize the literature, statutes, regulations, and case law gathered by the Consultant's research efforts. The primary data collected through surveys and interviews should be tabulated and presented to supplement the legal synthesis. The report shall include an analysis of the essential features required for effective fair disclosure of aviation related impacts. The report should also develop a model fair disclosure law and a set of best practices for use by airport operators and local government land use regulatory agencies in implementing fair disclosure laws and ordinances in a manner that requires the full disclosure to prospective home buyers of airport-related conditions and operations.

TI - Runway Status Lights: Takeoff Hold Lighting System Evaluation
PY - 2009/08//Technical Note
SP - 40p
AB - Takeoff hold lights (THL) are positioned along the runway centerline, and when illuminated, they are visible to an aircraft pilot at the beginning of the runway preparing for takeoff. Normally, these lights are off. A Runway Status Light (RWSL) System monitors the runway occupancy status and conveys this information to the pilots, ground vehicle operators, and others using special lighting components such as the THLs. Specifically, when a runway is occupied, the RWSL System turns on the THLs and provides a conspicuous visual warning to pilots preparing for takeoff that they should not continue. Project personnel from the Federal Aviation Administration (FAA) Airport Safety Technology Research and Development Subteam evaluated four THL configurations on Runway 13 at the Atlantic City International Airport. Three configurations contained a double row of red lights and one contained a single row of red lights. Project personnel collected data on the appearance of each configuration and recorded their findings on questionnaires. The results of this evaluation validated previous findings by the FAA Airport Safety Technology Research and Development Subteam that the double-row THL configuration spaced 6 ft from the runway centerline was more effective than the other three configurations. The 6-ft spacing created very distinct lines that did not, at any time, blend with the runway centerline fixtures. As a result, this configuration created a more conspicuous signal that was easily acquired by the pilots. Using double-row THLs significantly enhanced the THL system.

TI - Towbarless Towing Vehicle Operations - Evaluation of Braking Action and Vehicle Conspicuity
PY - 2009/08//Technical Note
SP - 34p
AB - General guidance on the operation of towbarless towing vehicles (TLTV) on airport operation areas is discussed with respect to braking during towing emergencies, painting, and lighting the TLTV and the aircraft being towed. Evaluations and recommendations are also given with regard to the topics discussed in the report. The braking evaluation was prompted by a runway incursion involving a Goldhofer AST-2 tractor and a Boeing 777 aircraft in which the 777 had none of its systems operational and no personnel present in the cockpit. A simulation analysis, conducted as part of the evaluation, indicates that a person in the cockpit qualified to apply the aircraft brakes probably could have stopped the TLTV/aircraft combination before the hold line and excessive damage would not have been caused to the nose gear of the aircraft during the aircraft braking action. This finding cannot be applied to other TLTV/aircraft combinations without analysis specific to that combination. The evaluation of painting and lighting (conspicuity) concerns was prompted by a number of airports reporting difficulty in seeing aircraft when being towed at night, particularly when the aircraft systems are not operational. The evaluation determined that TLTV/aircraft conspicuity may be increased by using brighter paint colors, reflective tape along the lower body panels of the TLTV, and additional warning lights on the body of the TLTV.

PY - 2009/08//Final Report
SP - 28p
AB - This report summarizes the results of three investigations of the use of the National Center for Atmospheric Research (NCAR) Snow Machine in anti-icing fluid endurance time tests. The first investigation focused on its performance for ethylene glycol-based Type II and Type IV fluids; the second examined its suitability for testing Type I fluids, and the third examined its suitability for testing at temperatures near and above 0 degrees C. Endurance time tests of Type II and IV fluids conducted in 2004 using the snow machine showed that it gave results that generally compared well with results from outdoor tests at the same conditions for all fluids except the only ethylene glycol-based fluid tested, ULTRA+. However, the number of tests was limited, and some had highly varying conditions. This report presents the results of subsequent ULTRA+ tests conducted to determine if the poor performance was more likely due to factors such as variable wind speed or direction, snowfall rate, or possibly experimental error, or to an inherent flaw in the snow machine for this particular fluid type.

TI - Toxicological Findings of Pilots Involved in Aviation Accidents Operated Under Title 14 CFR Part 135
PY - 2009/08//Final Report
SP - 12p
AB - Introduction: Under the United States Code of Federal Regulations (CFR), aircraft flown under Title 14 (Aeronautics and Space) Part 135 are operated as either commuter or on-demand flights. The rules governing the operation of and the crewmembers on board such aircraft are detailed within these regulations. Aircraft operated under 14 CFR Part 135 include medical flights, on-demand cargo flights, on-demand air-taxis, and scheduled/non-scheduled domestic passenger flights with or without air cargo. Pilots operating under these regulations carry with them the added responsibility of passenger safety or, for those involved in emergency medical flights, the importance of their role for the survivability of patients in critical condition. The purpose of this study was to examine the toxicological findings of pilots involved in aircraft accidents operated under 14 CFR Part 135. Methods: Toxicological and aeromedical findings from Part 135 pilots that were involved in fatal accidents between the years 1997 and 2007 were collected. Toxicological information was obtained from the Civil Aerospace Medical Institute’s (CAMI’s) Bioaeronautical Sciences Research Laboratory. Accident information and the probable cause and/or factor(s) of these accidents were obtained from the National Transportation Safety Board (NTSB). Results: Between the years 1997 and 2007, CAMI received biological samples of 142 pilots operating under Part 135 who had been involved in aviation accidents. Of these 142 pilots, 139 had sustained fatal injuries. Of the 139 fatalities, 33 (23%) were found to have taken at least one drug and/or had consumed alcohol prior to the accident. The compounds detected in these pilots ranged from the benign (such as acetaminophen) to illicit compounds (such as cocaine and marijuana). The NTSB attributed either the cause and/or a factor in the accident to drugs and/or alcohol use in 6 of these 33 accidents. Conclusion: Over the examined time period, aviation accidents operated under these regulations accounted for ~4% of all fatal aviation accidents received at CAMI for toxicological analysis. Generally, these aircraft were operated without harm to crewmembers, passengers, or bystanders. When accidents did occur, the majority were not the result of drug or alcohol impairment but, instead, were due to mechanical malfunctions, pilot error, and/or operation of aircraft in adverse weather conditions.

TI - Effects of Hydrogen Peroxide on Common Aviation Textiles
PY - 2009/08//Final Report
SP - 30p
AB - Modern transportation systems are subject to unintentional contamination from infected passengers, as well as deliberate contamination from criminals and political adversaries. Hydrogen peroxide has been used for years as a disinfectant in the medical community and is under consideration in the dilute vapor form as a decontaminant/disinfectant/sterilant for transportation vehicles like aircraft, buses, subway trains, ambulances, etc. Although the biological efficacy of STERIS Corporation’s Vaporized Hydrogen Peroxide (VHP® a registered trademark of the STERIS Corporation, Mentor, OH) technology has been demonstrated elsewhere, the compatibility of the process with typical aircraft materials has not been rigorously established. The present report documents a materials compatibility evaluation involving the effects of hydrogen peroxide exposure on the mechanical properties and flammability of the following commercial-grade textile materials: wool, nylon, polyester, Nomex®, and leather.

TI - Eliminating or Reducing the Need for Baggage Recheck for Arriving International Passengers
AB - International passengers arriving in the United States and connecting to another destination collect their baggage after they clear U.S. Immigration and before clearance by U.S. Customs and Agriculture with the exception of pre-cleared passengers. Non-cleared passengers reclaim their baggage before carrying it through to an area for inspection. At the same time, passengers are potentially monitored or questioned by federal officials with respect to various issues relating to their trip purpose and duration. During this process, the airline handles the passenger baggage several times. In reality, only a very small percentage of passengers are subjected to secondary processing. If the baggage for these passengers could be quickly identified and retrieved at the request of federal officials, this would permit other passengers to continue their journey unimpeded through the terminal without having to wait for and recheck their baggage. If this streamlining were possible, there could be a potential for improving operations with cost savings. The objectives of this research are to (1) identify potential alternative procedures that could be implemented to reduce or eliminate the need for the recheck of baggage for arriving international passengers at U.S. airports; (2) describe in detail the benefits and costs associated with these alternative procedures to airports, airlines, and federal agencies; and (3) compare and contrast potential alternative procedures with current practices.

TI - A Handbook for Developing, Implementing, and Overseeing Airport Capital Plans
AB - Airport capital improvements are dynamic and involve many elements, including phasing, financing, planning, design, and construction. Incorporating these various elements into a single plan, and then managing, overseeing, and communicating these multiple elements is a daunting task for airports and their interested stakeholders. Airport capital plans involve various stakeholders during their development, management, and oversight of the program. Capital plans change over time as projects move from planning to implementation, requiring updates to the scope, budget, financing, and schedule of those individual projects. Airport staff members from many different departments (e.g., planning, engineering, and finance), consultants, and outside agencies are involved in the project administration, each with their own set of priorities and responsibilities. The airlines and the FAA also have an interest in receiving timely and accurate information and have certain criteria that they are seeking when reviewing or evaluating the capital plan. It is not uncommon for roles and responsibilities to be misunderstood that inhibit effective communication. A collaborative business process that (1) describes all stakeholders and their respective roles, responsibilities, expectations, and information requirements and (2) identifies procedural steps is needed. This process can then be implemented at airports to facilitate communication among multiple stakeholders to ensure a successful capital plan. With many off-the-shelf or customizable software programs, capital plan information can be tracked overall or on an individual project basis. A defined process by which to best capture and communicate information used to administer the capital plan through a technological solution is also needed. This technological process is an important aspect of successfully maintaining the capital plan. This process is even more important once a project leaves the "planning" stage and enters the "implementation" stage. The objective of this research is to develop a handbook that identifies best management practices in all phases of development, management, financing, and oversight of airport capital plans and includes those elements, steps, and key milestones that are necessary to create a collaborative business process that ensures the consistent flow of information and maintains the capital plan. This includes reporting, updating, and tracking financial and individual project information and identifying the processes that facilitate communication between internal and external stakeholders (e.g., airlines, FAA, local and state officials). The handbook should also identify and translate the elements of the collaborative business process so that it can be incorporated into an information technology solution. This handbook will be developed for those individuals at an airport who have a responsibility in the development, financing, management, or oversight of the airport capital plan or who have information that is required to maintain and ensure the capital plan is current and up to date (e.g., project managers, CFOs, COOs, engineers). For the purposes of this project, an airport capital plan includes the capital improvement programs (i.e., individual projects) and the finance plan to support implementation.

TI - Practical Greenhouse Gas Emission Reduction Strategies for Airports
AB - There is increasing concern over aviation's contribution to greenhouse gas (GHG) emissions and associated environmental impacts affecting airports and the aviation industry. As environmental pressures continue to increase nationwide, it is imperative that airports take every opportunity to reduce their carbon footprint. Research is needed to assist airports, in cooperation with airlines and airport tenants, in reducing their GHG emissions by identifying practical, low-cost solutions that will assist them in better serving their passengers, customers, and host communities. By fostering the exchange of ideas and experiences through the development of a handbook and other tools that identify and evaluate best practices, airports can voluntarily commence implementation of such practices. The objective of this research is to develop a handbook and supporting application(s) that can assist airports in identifying, evaluating, and implementing practical, low-cost strategies to reduce and manage GHG emissions. The supporting application(s) should include an interactive companion application and a presentation that can be used by airports to educate and inform stakeholders. The handbook and supporting application(s) should address a range of strategies that can be implemented by all types of airports either directly or in partnership with airport stakeholders, including airlines, airport tenants, and host communities.

TI - Economic and Environmental Effects of the Introduction of a Cap and Trade Policy in Aviation
AB - Project 31 analyzed the effects of a potential introduction of a cap-and-trade policy in the aviation industry. Analyses were conducted through the joint application of the Aviation Environmental Portfolio Management Tool, in particular the APMT Economics module, and a global model of economic growth and greenhouse gas emissions, the MIT Emissions Prediction and Policy Analysis (EPPA) model. Where the EPPA model's outputs provide information on the world economy, changes of greenhouse gas emissions and the expected cost of carbon, APMT Economics focused on the airline industry, and provided outputs such as operating costs of airlines, demand, or airline fleets. While the project focused initially on the implications of a cap-and-trade policy, the tools enabled the study of a variety of other mitigation options -- for example, the extent to which mandates for renewable fuels in one sector can influence price and availability in other sectors, or the relative economic efficiency of sector-based regulations and standards versus broader economy-wide measures.

The efficiency of propellers and prop-fans has produced renewed interest in advanced "open rotor" engine designs. To contribute to the design process, noise predictions need to accurately identify the issues associated with these new designs and must forecast the annoyance of the population near airports due to the new noise sources.

TI - Legal Aspects of Airport Programs. Topic 3-03. Survey of Minimum Standards Commercial Aeronautical Activities at Airports
AB - Sponsors of airports that have received Federal Airport Improvement Program grants are under a federal obligation to operate their airport in a safe and efficient manner, while allowing access to all categories of aeronautical users on reasonable terms without unjust discrimination. The FAA encourages airport sponsors to adopt appropriate minimum standards for commercial use of the airport to help meet these potentially conflicting obligations. A compendium of comparative minimum standards would assist airport management and airport lawyers in developing appropriate standards that comply with their federal obligations. Currently, there is no comprehensive source of information to which airport lawyers can turn for minimum standards on commercial aeronautical activities at airports. The objective of the research is to identify commercial aeronautical activities (e.g., full service FBO or avionics repair) that are customary at airports, and rank them according to frequency of occurrence. The research should also identify minimum standards typically applied to these activities, and categorize minimum standards by type of commercial activity and by subject area, e.g., minimum insurance requirements or minimum square footage.

TI - Review of Aircraft Self-Spacing Concepts: Implications for Controller Display Requirements
PY - 2009/07//Technical Note
SP - 30p
AB - This report summarizes the concepts and the simulations conducted on pilot self-spacing and self-separation between 2005 and 2007 and focuses on the implications for air traffic control information needs and display enhancements. It follows a previous literature review on these concepts by McAnulty and Zingale (2005). In 2007, air traffic levels were predicted to double or triple by the year 2025. To manage this increase, the Federal Aviation Administration (FAA) has been planning to modernize the National Airspace System and to develop new concepts, procedures, and tools that will alter the roles and responsibilities of pilots and controllers. These concepts include the delegation of some responsibilities and procedures to the flight deck of appropriately equipped aircraft. It is anticipated that not all aircraft will be equipped to conduct these procedures at the same time. Therefore, some aircraft will be able to conduct such procedures as self-spacing and self-separation earlier than others, resulting in a mixed-equipage environment. Based on the level of traffic management required, controllers will need information to differentiate aircraft. The FAA must conduct extensive testing on these concepts and on the type of support provided to controllers to ensure that efficiency goals are realized while risks are minimized.

TI - Comparing the Tower Operations Digital Data System to Paper Flight Progress Strips in Zero-Visibility Operations
PY - 2009/07//Technical Report
SP - 116p
AB - The current experiment used a high-fidelity, human-in-the-loop simulation to compare the Tower Operations Digital Data System (TODDS) to paper flight progress strips (FPSs) during zero-visibility Airport Traffic Control Tower operations. Sixteen current controllers participated in groups of two. Each group received touchscreen and TODDS training before completing eight practice and eight test scenarios. The participants worked at both the ground and local control positions under four experimental conditions. The participants used either the Integrated TODDS (electronic flight data integrated with surface surveillance, weather information, and digital-taxi communications), FPSs with Airport Surface Detection Equipment – Model X (ASDE-X), Perceptual-Spatial TODDS (electronic flight data integrated with weather information and digital-taxi communications, but no surface surveillance), or FPSs only, to control airport traffic. The participants had a Standard Terminal Automation Replacement System (STARS) display in all four conditions, but did not have an out-the-window view. Dependent measures included the number and duration of airport operations, number and duration of communications, TODDS usability, and participant opinion. The data revealed advantages for surface surveillance and TODDS. The Integrated TODDS provided additional benefits that may help reduce the risk of runway incursions, ease the flow of surface operations, and support the Staffed Virtual Tower concept.

TI - Operational Usage Information for a Commuter Propeller
PY - 2009/07//Final Report
SP - 70p
AB - Wichita State University (WSU) supports the Federal Aviation Administration (FAA) research in the area of Operational Loads Measurement of commuter and general aviation aircraft. This research is aimed primarily at acquiring and reducing typical in-service usage data for the purpose of better understanding the flight loads experienced by the airframe. The program includes developing improved methods and criteria for processing and presenting large amounts of data. These activities result in information that can (1) lead to the understanding of the service-related factors affecting the operational life of the aircraft and (2) allow the FAA to reassess continued suitability of existing certification criteria. The University of Dayton Research Institute (UDRI) published the results from the processing and analysis of digital flight recorder data obtained from 910 flights of 30 BE-1900D aircraft during typical operational usage by a single commuter airline. These aircraft employ propellers with composite structures. The data used by UDRI also contained some information on engine and propeller usage, such as engine revolutions per minute (rpm) and torque and time at propeller reversal. This report documents the efforts of WSU to derive statistical summaries of aircraft usage data, ground operations data, and flight operations data pertaining to the propellers from this database. Statistical data are presented for parameters such as torque correlated with rpm, time in propeller reversal, alpha, and unsteadiness in alpha due to gust velocities. The scope of activities performed encompasses the service-related factors that affect the operational life of the propeller, as defined by the propeller manufacturer. WSU has generated the processed data in statistical formats that can enable the FAA, the propeller manufacturer, and the airline to better understand and control those factors that influence the structural integrity of these components.

TI - Roadmap for Weather Integration into Traffic Flow Management Modernization (TFM-M)
PY - 2009/07
SP - 142p
AB - This report provides recommendations for aligning new Collaborative Air Traffic Management Technologies (CATM-T) with evolving aviation weather products to improve NAS efficiency during adverse (especially severe) weather conditions. Key gaps indentified Include: Improving or developing pilot convective storm avoidance models as well as models for route blockage and capacity in severe weather is necessary for automated congestion prediction and resolution; forecasts used to characterize uncertainty that can be used by CATM tools, and, explicitly forecast key parameters needed for translation of weather to capacity impacts; time based flow management will require substantial progress in both the translation modeling and in predicting appropriate storm avoidance trajectories; near term efforts should focus on integration of the Traffic Management Advisor (TMA) with contemporary severe weather products such as the Corridor Integrated Weather System (CIWS); Human factors studies on product design to improve industrial decision making; Improved Collaborative Decision Making in 'difficult' situations, and the use of the probabilistic products are also essential; studies need to be carried out to determine how well en route and terminal capacity currently is being utilized during adverse weather events as to identify the highest priority areas for integrated weather-CATM system development.

TI - Validating Information Complexity Questionnaires Using Travel Web Sites
PY - 2009/07//Final Report
SP - 26p
AB - With the prevalent use of visual interfaces and the increasing demand to display more information, information complexity in human-computer interfaces becomes a major concern for technology designers. Complex interfaces affect the effectiveness, efficiency, and even the operational safety of a system. Previously, researchers at the Federal Aviation Administration developed two questionnaires to evaluate information complexity of air traffic control displays. This study adapted the questionnaires for commercial computer interfaces and validated them with two types of tasks on three travel Web sites. The results demonstrated that both questionnaires had acceptable reliability, validity, and sensitivity.

TI - Evaluation of Next-Generation Vision Testers for Aeromedical Certification of Aviation Personnel
PY - 2009/07//Final Report
SP - 36p
AB - Introduction: The Federal Aviation Administration (FAA) allows the use of a variety of vision screening devices to evaluate a pilot applicant’s vision performance for medical certification purposes. This study compares human subject test scores obtained using two new vision testing instruments (Optec 5000 and Titmus i400) with those from previously approved counterparts (Optec 2000 and Titmus 2A), which have been discontinued by their manufacturers. Method: Testing included near, intermediate, and distant visual acuity, when appropriate, as well as heterophoria and color perception. Aside from color vision deficiencies, visual performance for all subjects was within the minimum Federal Aviation Regulations (FAR) vision requirements for Class II airmen. The test subject population included 36 individuals who ranged in age from 18 to 66 (34.4 ± 14.2). Six subjects were 50 years of age or over, requiring intermediate vision testing and 12 were color deficient. Analysis was designed to detect statistically significant differences between the test scores obtained with the new instruments vs. the older models. Results: The results of this study indicate that both new instruments provided visual acuity and heterophoria scores that are statistically equivalent to the older models. Color vision test scores for the Titmus i400 were found to be statistically equivalent to those of the Titmus 2A, with little or no change in failure rate. Although the color vision scores of the Optec 5000 were statistically equivalent to those of the Optec 2000, it failed 50% of the color normal subjects in the study. Conclusion: FAA approval is recommended for the Titmus i400 for use in all applicable aviation vision tests. Conditional approval is recommended for the Optec 5000, provided the Aviation Medical Examiner has an appropriate alternate color vision test should individuals be identified as color deficient during the certification exam.

TI - Evaluating Airfield Capacity
AB - Airport capacity and its related implementation is a critical evaluation component of most airport planning projects; therefore, it is important that appropriate guidance be available to the aviation industry on measuring capacity and delay. While airport sponsors often employ more sophisticated methods for evaluating capacity, the FAA's Advisory Circular 150/5060-5 Airport Capacity and Delay (AC) is the formal Federal Aviation Administration (FAA) guidance on this topic. To use the AC or the Airport Capacity Model (ACM), airport planners must choose one or more runway nomographs that, singly or collectively, most closely match the airport's runway layout. There are also complex, higher fidelity simulation models which can be resource and data intensive, such as SIMMOD and TAAM. With the many current and evolving factors and limitations that influence capacity at a given airport, there is a need to enhance capacity modeling tools and techniques to provide the accuracy appropriate to make timely and cost-effective critical project funding decisions. The objective of this research is to develop a guidebook to assist airport planners with airfield and airspace capacity evaluation. The guidebook will address airport airfield and airspace capacity planning at all tyes of airports. The term "airfield" capacity refers to runways, taxiways, apron areas, and aircraft parking positions. "Airspace" capacity for this research is defined as the approach and departure procedures in the immediate vicinity of an airport that directly affects airfield capacity.

TI - Air Traffic Control: Potential Fatigue Factors
PY - 2009/06/29
SP - 22p
AB - This report presents the results of The U.S. Department of Transportation Office of Inspector General's (OIG's) audit of fatigue factors that could impact air traffic controllers. OIG conducted this review at three Chicago area air traffic control facilities: Chicago O’Hare International Airport Air Traffic Control Tower (Chicago O’Hare), Chicago Terminal Radar Approach Control Facility (Chicago TRACON), and Chicago Air Route Traffic Control Center (Chicago ARTCC). These 3 facilities are among the top 10 busiest air traffic control facilities in the United States. Nationwide, during 2007, Chicago O’Hare was the second busiest air traffic control tower with 927,000 airport operations, Chicago ARTCC the fourth busiest air route traffic control center with 2.8 million operations, and Chicago TRACON the sixth busiest TRACON with 1.4 million operations. OIG conducted this audit at the request of Senator Richard Durbin of Illinois. Senator Durbin expressed specific concerns that staffing shortfalls, longer hours on the job, and a growing shortage of certified controllers may be causing controller fatigue at these critical facilities. He asked that OIG review factors that could potentially cause controller fatigue at these locations. Consistent with Senator Durbin’s request, OIG's audit objectives were to (1) identify and evaluate key factors that could cause controller fatigue at Chicago O’Hare, Chicago TRACON, and Chicago ARTCC and (2) identify what measures FAA has taken to mitigate potential controller fatigue at these locations. OIG conducted its audit between January 2008 and February 2009 in compliance with generally accepted government auditing standards. Briefly, OIG identified a number of factors at Chicago O’Hare, Chicago TRACON, and Chicago ARTCC that could create potential fatigue conditions for controllers. These factors include minimal hours between shifts and counter rotational shifts with progressively earlier start times; scheduled overtime; and on-the-job training (OJT), which requires a high level of concentration and focus. OIG also found that overtime hours at Chicago O’Hare and Chicago TRACON had increased significantly between fiscal year (FY) 2006 and FY 2007 (by 75 percent and 67 percent, respectively). However, the potential impact on fatigue was negligible because controllers did not always work all days of a scheduled 6-day (i.e., overtime) work week. While all three facilities have high traffic volumes and complex airspace, their staffing levels exceeded established staffing ranges for those locations. Those ranges do not, however, consider the ratio of trainees to certified controllers. Fatigue can have serious safety implications and has been identified by the NTSB as a potential contributing factor in several operational errors (where controllers fail to maintain required distances between aircraft). Yet, FAA does not consistently address human factors issues, such as fatigue and situational awareness, during either the preliminary or final operational error investigation process. FAA is taking several actions at the national level to address NTSB recommendations regarding fatigue. These actions include amending FAA Order 7210.3 to (1) increase the time available for rest (between shifts) from 8 hours to 10 hours, (2) increase the time available for rest after working a midnight shift on the fifth day of the week from 12 hours to 16 hours for facilities that utilize a 6-day work week, and (3) allow controllers to sleep or rest when not controlling traffic.

TI - Use of Near-Term Operational Changes to Mitigate Environmental Impacts of Aviation
AB - Concerns about the aviation's environmental impact have prompted research efforts around the world. Much of this research has focused on changes to future aircraft and engine designs: although these hold the prospect of significant environmental impact reductions on a per flight basis, it will take a long time for them to be developed and propagate through the operational fleet in sufficient numbers to have a significant impact on overall emission levels. Until then, strategies that reduce the environmental impacts of existing aircraft are needed. Therefore, there is a need to identify and evaluate ways to reduce the environmental impacts of aviation in the near term. Such changes would involve minor adjustments to operating procedures or limited equipment/infrastructure changes. The goal of Project 32 was to systematically evaluate and rank all the potential near-term operational changes against a common set of environmental impact and feasibility criteria, and hence make it possible to determine the relative potential of the various options and to understand which ones should be given priority.

TI - Understanding Airport In-Terminal Concession Programs
AB - Airport in-terminal concessions provide an important passenger service amenity but also can provide significant financial benefits to the airport. During the past 10 years, many airports have evolved from generic non-branded food and news locations into shopping mall centers throughout the airport featuring national and regional food concepts and a wide variety of specialty retail brands. With the shift in approach, the planning for concessions and the business terms for concession agreements have changed dramatically. The objective of this research is to develop a resource manual that summarizes the considerations in concessions program planning, customer service standards, and business terms development. The project will also include a survey of the rental terms and total occupancy costs for major classifications of airport concessions at a comprehensive sample of large, medium, and small airports across the nation. Concession program planning will include issues related to selection of brands, local concepts, and analyzing passenger flows and adjacencies. Rules of thumb with respect to the amount of space dedicated to concessions by categories and general achievable expectations for sales per enplaned passenger and per square foot should also be developed. Best practices in customer service standards should be outlined. The project deliverables will also include a survey tool and an on-line database that can be updated on an ongoing basis to reflect changing occupancy costs to serve as an interactive tool for detailed comparison of approaches by airports.

TI - Decision-Making Tool for Evaluating Passenger Self-Tagging
AB - The evolution of self-service passenger processing over the last 10 years has had a significant impact on airport terminal facility design and operation. Airport terminal departures halls are no longer vast spaces with linear ticket counters staffed by an army of airline agents. Today, passengers are immediately greeted by a field of self-service kiosks that provide more choices and reduce queuing time. The recently opened Terminal 5 at London Heathrow was specifically designed around self-service check-in options, including passenger self-tagging, based on the target of accommodating 80 percent of originating passengers with self-service and the remainder with traditional full-service check-in options. As self-service check-in continues to evolve, the next logical step is for passengers, who are checking baggage for transport in the aircraft's cargo hold, to apply bag tags and place their checked bags on the conveyor belt for induction into the baggage handling system. While this activity is currently prohibited in the United States by Transportation Security Administration regulations, other North American cities, such as Montreal, as well as several European countries are allowing it. Passenger self-tagging has the potential to not only provide more check-in choices and expedite the process but also to greatly impact airport terminal facility design by increasing the capacity of existing facilities and reducing the space requirements for new facilities. However, the implications (positive or negative) of passenger self-tagging are not widely understood. With baggage handling and screening systems becoming an increasingly more important factor in airport terminal design and operation and passenger self-empowerment becoming a key method for increasing passenger level of service, further investigation is required to help operators and regulators in the U.S. aviation industry to better understand the future implications for passenger self-tagging. The objective of this research is to establish the current status of passenger self-tagging in the locations where it is allowed, identify the future implications for passenger self-tagging in the United States, and make recommendations for accommodating passenger self-tagging. Part 139 of title 14, Code of Federal Regulations, requires airports that serve: 1) scheduled passenger-carrying operations of an air carrier operating aircraft designed for more than 9 passenger seats; and 2) unscheduled passenger-carrying operations of an air carrier operating aircraft designed for at least 31 passenger seats, to receive operating certificates from the Federal Aviation Administration (FAA). Operators of Part 139 airports are also required to meet certain aircraft rescue and fire fighting (ARFF) standards. In March 2001, the FAA tasked the Aviation Rulemaking Advisory Committee (ARAC) to develop a Notice of Proposed Rulemaking to identity ARFF requirements that should be added, modified or deleted. Despite the ongoing rulemaking process, some aviation stakeholders are recommending that airports comply with certain National Fire Protection Association (NFPA) standards and other NFPA-related requirements or International Civil Aviation Organization (ICAO) fire fighting standards.
Frequently, commercial airport operators are asked to estimate the magnitude of toxic emissions from airport-related sources. These requests may come from government officials, courts or concerned community groups. One of the key categories of potentially toxic emissions is Hazardous Air Pollutant (HAP) emissions and the most important source of airport related HAPs compounds at most commercial airports is idling jet engines. This is because the HAPs emissions of modern jet engines are very small at power settings greater than idle. It is therefore critical to understand the rate of HAPs emissions at low power settings. These emissions will vary as a function of thrust setting, environmental variables (especially temperature) and engine type. In order to properly estimate airport HAP emissions it is necessary to better understand the aircraft engine emission factors as a function of these variables.
It is important for the aviation industry and airports in particular, to better understand the potential impact of airfield and aircraft deicers on the environment. EPA made an initial estimate in 2000 indicating nearly 21 million gallons of aircraft deicers where used in the
This task was to identify issues associated with the visibility of airfield signs and markings.

However, if the intensity of the internal standard (IS) is low, indicating interference factors, the test could be considered “inconclusive.” A quantitative hypothesis, A = (R×I×S)/L, serves as the “cutoff” for the acceptable signal-to-noise (S/N) ratio for the IS in making “negative/inconclusive” decisions, where A: acceptable S/N ratio for internal standard; R: relative response of the IS and the analyte (same concentration); I: concentration of the IS; S: (minimal S/N ratio); and L: limit of detection. The hypothesis was empirically tested using 9-carboxy-11-nor-Δ9-tetrahydrocannabinol (THC-COOH) analyte, THC-COOH-d3 IS, and ibuprofen and hydrogen peroxide (H2O2) as interference factors. Urine specimens containing 0–5 ng/mL of THCCOOH were spiked with various quantities of ibuprofen or H2O2, followed by liquid-liquid extraction, derivatization, and GC-MS analysis under selected-ion-monitoring mode. Among the “adulterated” test specimens evaluated, those with a S/N for the internal standard below the acceptable IS S/N “A,” the quantitative criterion was indeed found to provide a useful guide for making negative/inconclusive decisions. This equation could be programmed into the instrument software to flag results as being inconclusive when they do not meet the criteria described in this paper.

Color has been shown to aid operators in search and organization tasks; however, it can also cause cognitive tunneling and add to task complexity. This paper details the results from an experiment designed to evaluate increasing color categories in an attempt to objectively measure how the use of color in air traffic control-related displays affects performance. Results showed that the use of six color categories, as compared to three, significantly improved subjects’ accuracy in performing search and problem-solving tasks. However, beyond six color categories, performance accuracy was not significantly aided and was possibly degraded. In addition, errors of omission significantly increased when the number of color categories increased from six to nine. This study demonstrated that, especially under high workloads, color categorization beyond six groupings added to overall task complexity as a function of workload, even more than an environmental complexity factor that depends on task requirements.

However, a major remaining impediment to the operation of such aircraft is the cruise noise signature. Sonic boom noise issues are different from many other aspects of aircraft noise in that the potential annoyance occurs en route, along the flight path rather than just near airports. Maximum utility will require supersonic flight over land, currently prohibited by law. Recent research on shaped sonic booms has indicated low boom designs are possible and result in significantly less objectionable signatures than classic booms of the 1960s - 1980s. Supersonic aircraft operation and sonic boom signatures were investigated for low boom designs, as the overarching goal of Project 8.

ATC facilities are required to log all Traffic Management Initiatives (TMIs), coordinate the implementation of some initiatives with the Air Traffic Control System Command Center, and communicate TMIs to Traffic Management Specialists at all affected facilities and to the controllers within their facility. The Federal Aviation Administration developed the National Traffic Management Log (NTML) to provide a single system for automated coordination, logging, and communication of TMIs throughout the National Airspace System. This report describes the results of an empirical comparison of TMI processing with and without the NTML. Researchers observed benefits in completion times, potential for user error, and workload. Furthermore, the completion time and potential for error remained relatively unaffected by TMI complexity. These results suggest that the NTML will continue to provide benefits as ATC complexity increases in the future.

Wrong Runway Departures PY - 2007/07 SP - 68p AB - In light of the recent crash of Comair, Inc. (doing business as Comair Airlines doing business as Delta Connection), flight 5191 in Lexington, Kentucky, the Federal Aviation Administration's Aviation Safety Information Analysis and Sharing center conducted a review of event reports that involved airplanes departing from or taxiing into position on a wrong runway. The review involved gathering data from multiple databases (1981 through 2006); identifying event reports of interest; reviewing those reports to find contributing factors; identifying, assigning, and scoring mitigations. The review showed that wrong runway events occurred at many airports and under varying circumstances; however, they occurred most frequently at four airports: Cleveland Hopkins International Airport, Houston Hobby Airport, Salt Lake City International Airport, and Miami International Airport. These airports share the following common elements or contributing factors: (1) Multiple runway thresholds located in close proximity to one another; (2) A short distance between the airport terminal and the runway; (3) A complex airport design; (4) The use of a runway as a taxiway, and (5) A single runway that uses intersection departures.

In support of a Department of Homeland Security project, the transmittance properties of aircraft windscreens were measured at the Federal Aviation Administration’s (FAA´s) Civil Aerospace Medical Institute (CAMI) for both visible and invisible optical radiation. This paper focuses on windscreen transmittance in the ultraviolet (UV) (< 380 nm) and visible (380-780 nm) portions of the optical spectrum. Transmission measurements were performed on eight aircraft windscreens. Three windscreens were from large commercial jets (MD 88, Airbus A320, and Boeing 727/737); two from commercial, propeller-driven passenger planes (Fokker 27 and the ATR 42); one from a small private jet (Raytheon Aircraft Corporation Hawker Horizon); and two from small general aviation (GA), single-engine, propeller-driven planes (Beech Bonanza and Cessna 182). The two GA aircraft windscreens were plastic (polycarbonate); the others were multilayer (laminated) composite glass. UV transmittance for both glass and plastic windscreens was less than 1% for UV-B (280-320 nm) radiation. In the UV-A portion (320-380 nm) of the spectrum, transmittance differences increased from 0.41% to 53.5%, with plastic attenuating more UV radiation than glass. For visible light, average transmittance from 400-600 nm (violet to orange) was similar (82.8% ± 4.6%) for both windscreen materials, while from 625 to 775 nm (orange to red), the difference in average transmittance increased from 9.1% to 40.0%, respectively, with plastic transmitting longer wavelengths more efficiently. Both types of windscreens blocked most of the more harmful UV-B radiation; however, glass laminate windscreens allowed higher levels of potentially damaging UV-A radiation to be transmitted than did plastic. Professional pilots who routinely fly at higher altitude for longer periods of time than private pilots should take special precautions to protect their eyes from UV exposure.

In a 2003 study, 4 SSRIs—citalopram, fluoxetine, paroxetine, and sertraline—were found in 61 pilot fatalities of civil aviation accidents that occurred during 1990–2001. However, it was not known whether these pilots had had disqualifying psychological conditions, including depression, and had properly reported the use of the antidepressants. The aeromedical history of the pilots was retrieved from the Federal Aviation Administration's (FAA's) Medical Certification Database; additional pilot medical information and the cause/factor of the accidents were obtained from the National Transportation Safety Board's (NTSB's) Aviation Accident Database. Fifty-nine pilots had medical records in the FAA's Certification Database. The database did not contain medical records of 2 pilots—1 had never received a medical certificate and another had a Canadian pilot and medical certificate. Although driving under the influence was self-reported by 22 of the 59 pilots during their past aeromedical examinations, disqualifying psychological conditions were self-reported in the past examinations of only 7 (12%) of the 59 pilots, and the use of an SSRI was reported by 3 of the 7 pilots. In later examinations, 6 of the 7 indicated that they were free from the conditions and not taking SSRIs; thus, they were reissued medical certificates. Such conditions and/or drug use were not self-reported in the aeromedical records of the 52 (88%) pilots. Nevertheless, the NTSB investigations revealed that 12 (20%) of the 61 pilots had a history of a psychological condition and/or an SSRI use, as suggested by their personal medical records. Psychological conditions and/or the use of drugs were determined to be the cause or a factor in 19 (31%) of the 61 accidents. These findings reconfirm that SSRIs were used by the aviators but were not reported in their last aeromedical examinations.

Average Control Duration, Aircraft Mix Index, Average Lateral Distance, Average Vertical Distance, Number of Handoffs, Number of Point Outs, Number of Transitioning Aircraft, and Number of Heading Changes were used as predictors in two stepwise logistic regression analyses conducted for the high-altitude and low-altitude sectors. In the high-altitude sample, variables included in the final model (Number of Heading Changes, Number of Transitioning Aircraft, and Average Control Duration) accurately classified OE and RO samples for 80% of the cases. In the low-altitude sample, variables included in the final model (Number of Point Outs, the Number of Handoffs, and the Number of Heading Changes) accurately classified OE and RO samples for 79% of the cases. Although logistic regression cannot be used to determine causation, it effectively identified variables that predicted the occurrence of OEs.

The NASA Ames Research Center Fatigue Countermeasures Group (FCG) was contracted by CAMI to conduct the study. To meet the goals of the study, this report contains a literature review on fatigue as potentially experienced by flight attendants, an evaluation of currently used (actual vs. scheduled) flight attendant duty schedules, and a comparison of these schedules to the current CFRs. The report additionally reviews fatigue-related incident/accident information from the Aviation Safety Reporting System (ASRS) and the NTSB database. One report section describes the application of three different performance and fatigue models to assess how flight attendant duty schedules contribute to increased levels of fatigue and predicted changes in performance. The report concludes with 6 recommendations concerning issues that require further evaluation, including: (1) Survey of Field Operations. To assess the frequency with which fatigue is experienced, the situations in which it appears, and the consequences that follow; (2) Focused Study of Incident Reports. To better understand details of the incidents; (3) Field Research on the Effects of Fatigue. To explore physiological and neuropsychological effects of fatigue, sleepiness, circadian factors, and rest schedules on flight attendants; (4) Validation of Models for Assessing FA Fatigue. An important step to understanding whether and how models could be used in conjunction with field operations; (5) International Carrier Policies and Practices Review. To learn how other countries address these issues and with what results; and (6) Training. FAs could benefit from information on fatigue, its causes and consequences, its interaction with circadian disruption, and how and when to employ countermeasures (e.g., scheduled naps, physical activity, social interaction, caffeine).

Specifically, (a) security screening requirements have altered passenger flows and the desirability of locating commercial activities beyond the security checkpoints; (b) electronic check-in, both in terminal and before arrival at the airport, are totally changing requirements for the public counter and back office space for the check-in process; (c) the growth of low-cost carriers is having a strong effect on the criteria for design, in terms of level of service standards and space configurations desired by the airline customers; and (d) the newer pattern of quick turn-arounds for aircraft, which increases the use of each gate, is increasing the space requirements beyond check-in, as more people have to be accommodated in the gate areas in any given period. The planning and design for the new JetBlue terminal at New York/Kennedy airport illustrates these points. The increased pressure for "low-cost terminals" accentuates the importance of proper airport terminal planning. Planners and designers for all sizes of airports are struggling with how to make passenger terminals that provide good value and level of service efficiency that meet the criteria of the new range of stakeholders in airport terminals (e.g., TSA, low-cost carriers, concessionaires) and the new range of security and electronic procedures. Up-to-date, practical information is needed that not only can address the current issues but will provide the flexibility to accommodate emerging trends and issues. Often airport managers, public officials, and planners do not necessarily have the breadth of knowledge or experience about the many factors, nuances, and alternatives to be considered in planning and designing an airport passenger terminal. This is especially true at smaller agencies with limited staff. It would be useful for them to have a guidebook that can be used when planning and designing the various components of a passenger terminal. This guidebook would facilitate discussion during the planning process and allow an airport manager to ask an airport planner or designer "Has this possibility been addressed?" or to respond to public inquiries such as, "Did you think of this idea?" An FAA document on the subject, "Planning and Design Guidelines for Airport Terminal Facilities" (AC 150/5360-13) was prepared in 1988. Airport passenger terminal planners and designers need up-to-date information on how to provide good value and efficiency to meet needs of stakeholders and accommodate changing technologies, materials, regulations, and operational factors for both large and small airports. The objective of this project is to produce an Airport Passenger Terminal Planning Guidebook. The guidebook should include sections (a) describing the airport passenger terminal planning process and (b) identifying current and future issues, trends, impacts, and solutions in airport passenger terminal planning.

When referring to airport capacity, the focus is usually placed on runway and airspace capacity. However, the last few years have seen rapid changes in airport terminals as more space is being taken up by security processing requirements, and restored growth in passenger traffic is further stressing terminal facilities. In planning for efficient passenger flow and passenger queuing space in an airport terminal, limited work has been performed to understand the unique Level of Service (LOS) requirements and space requirements of passengers. In fact, much of the research that is commonly used as reference for understanding passenger behavior does not even come from the aviation environment, but rather from terminal studies conducted at the Port Authority Bus Station and the Penn Train Station in New York City by John J. Fruin back in the early 1970's. The airport passenger differs from the commuter passenger observed by Fruin since an airport passenger is more likely to be carrying baggage, traveling with associates or family, and spending longer dwell times in the terminal. A rigorous study of passenger movement and queuing characteristics in congested terminals is needed to help to provide guidance to planners updating terminal facilities to meet future levels of demand. The objective of this research is to develop accurate guidelines for planners and other aviation professionals regarding planning requirements for passenger movement and queuing characteristics in an airport environment.

Yet, air service development teams have little practical guidance on what techniques exist, and which are effective. Air service development (ASD) includes the attraction, initiation, expansion, retention, or any improvement of air service and can include changes in pricing, frequency, capacity, hub-connectivity, or the number of destinations. ASD techniques can include incentives; subsidies; guarantees; changes to rates and charges; marketing; cost-reduction measures; airport-community-airline partnerships; reducing third-party costs, such as ground handling or fueling services; or any other approach taken to encourage development of air service. Currently no single resource document summarizes experience to date in ASD or offers guidance as to when and how different techniques should be used. The objective of this project is to develop a guide that describes techniques that airports and communities can employ in their efforts to develop passenger air service. The guide should include fundamental information to assist airports and the communities they serve to understand the nature of ASD within the general context of the airport, community, and airline business perspectives.

About 30 APM systems are operating at airports worldwide; roughly one-half of these systems are at U.S. airports. APM systems are implemented at airports to facilitate passenger and employee movement, generally within the confines of the airport. They typically operate from passenger check-in areas to airplane gates and between gates, allowing more people to move more quickly over longer distances, connecting large, often dispersed airline terminals. More recently, APM systems have been designed to connect airport terminals with parking facilities, car rental services, regional transportation services, hotels, and other related employment and activity centers. APMs are vital to the operation of many airports, in that they provide the fastest and sometimes the only means to travel within an airport. Serious problems arise for APM passengers and for an entire airport when an airport APM system does not operate well or stops entirely. Operators of APMs at airports routinely collect data and develop performance measures to monitor and manage their performance. These measures typically address service availability, service reliability, cost, and operation and maintenance contract compliance. Operators of APM systems at airports would like to make meaningful comparisons of their performance with that of APMs at other airports to assess and improve their performance. A key challenge to conducting meaningful comparisons is that no two airport APM systems are identical. For example, the systems have different sizes, configurations, technologies, maintenance provisions, ages, and operating environments. In addition, performance comparisons must be based on comparable performance measures using comparable data. Currently, there are no performance measures or data-collection practices common to all airport APMs, and research is needed to develop meaningful tools for measuring and comparing performance. The objective of this research is to develop a user-friendly guidebook for measuring performance of automated people mover (APM) systems at airports. The guidebook should identify a set of performance measures and associated data requirements for APM operators at airports to assess and improve performance, compare APM systems, and plan and design future APM systems. The performance measures should address the efficiency, effectiveness, and quality of APM systems at airports, particularly focusing on impacts on APM passengers and on airport performance.

Planes are larger and many airports have changed their character and configuration, becoming far bigger and more complex. Some new airport designs include more and larger terminals and facilities that may be spread over large areas. As a result, these airports have become much less walkable with long distances between facilities and services. Because airline travel is very time-sensitive, it is critical that passengers and employees, of all ages and physical abilities, be able to travel efficiently with luggage, strollers, wheelchairs, or other encumbrances. Recognizing the importance of mobility to passengers and employees, some airports have planned or implemented automated people mover (APM) systems. APMs are systems with fully automated operations, featuring vehicles that on guideways with an exclusive right-of-way. These systems have been developed and implemented in various sizes and configurations beginning in the 1970s and installed in about 120 locations worldwide, including airports, leisure facilities, institutions, and urban areas. APM systems are distinct from traditional, heavy and light rail public transportation, in that they operate without drivers or station attendants. Typically, APM systems use a narrower right-of-way and smaller vehicles than traditional public transportation services. The advent of computerized operations and increased congestion, along with a desire for improved mobility and integration of activities, has spurred the development of APM systems. About 30 APM systems are operating at airports worldwide; roughly one-half of these systems are at U.S. airports. APM systems were implemented to facilitate passenger and employee movement generally within the confines of an airport, generally from passenger check-in areas to airplane gates and between gates, allowing more people to move more quickly over longer distances, connecting large, often dispersed airline terminals. More recently, APM systems have been designed to connect airports terminals with parking facilities, car rental services, regional transportation services, hotels, and other related employment and activity centers. Planning tools are needed (1) to assist airports in considering the feasibility of these systems and (2) to plan and implement APM systems, when appropriate. Research is also needed to provide a historical perspective of APM systems at airports worldwide, a review of existing APM systems at airports, a discussion of available and evolving APM technologies, and a summary of alternative APM service configurations. Research results should be presented in a guidebook that provides practical methodologies and planning criteria for conceptual development and evaluation of airport APM systems. Finally, the guidebook should address implementation of APM systems at airports. The objective of this research is to prepare a comprehensive guidebook for planning and implementing APM systems at airports. The guidebook should include, as appropriate, a CD-ROM with interactive tools that will assist airports to plan and implement an APM system. The scope of this research includes APM systems that provide transportation on airport grounds as well as access to remote facilities (e.g., airport parking, car rental facilities, hotels, off-airport public transportation, and other related activity centers).

The computer models used for these analyses are either based on simple procedures using widely available spreadsheets (hereinafter referred to as spreadsheet models) or sophisticated, discrete event models that often include animated outputs (hereinafter referred to as discrete event models). The discrete event models are usually created on proprietary software. Although some situations require the use of discrete event models, often good preliminary and, in some cases, final answers to many terminal planning and design issues can be obtained using spreadsheet models. Development of user-friendly spreadsheet models to analyze common issues related to airport terminal planning and design would benefit employees of airport operators by providing them with tools they can immediately use, without having to "reinvent the wheel" as they confront issues that are new to them but have been solved elsewhere. In addition, despite widespread use of computers, the profession has not developed a widely available compendium of computer-based models to advance the capability of airport staff and airport planners in general. The objectives of this research are to (1) develop a user-friendly spreadsheet model (or models), with an accompanying manual, to analyze issues common to airport passenger terminal planning and design and (2) produce a compendium that identifies the types, scopes, and availability of spreadsheet and discrete event models that can be used by airport operators for airport passenger terminal planning and design. The prime users of this project's products are intended to be employees of airport operators who are involved in terminal planning and design.
