  • Modeling Performance and Noise of Advanced Operational Procedures for Current and Future Aircraft
    Modeling Performance and Noise of Advanced Operational Procedures for Current and Future Aircraft
    Thomas, Jacqueline ;
    Hansman, R. John
    2017-02-01 | PDF
    Increasing concerns regarding aircraft noise has encouraged the push to reduce noise via operational adjustments. The objective here is thus to expand analysis capabilities to enable modeling of the impact on aircraft noise due to advanced operational approach procedures, such as delayed deceleration approaches and thrust cutback scheduling on take ...

  • Microphysical Modeling Analysis of ACCESS 2 Aviation Exhaust Observations
    Microphysical Modeling & Analysis of ACCESS 2 Aviation Exhaust Observations
    Jacobson, Mark Z. ;
    Lele, Sanjiva K.
    2016-12-15 | PDF
    As the popularity of and global access to air travel expands, quantifying its impact on climate and air pollution becomes increasingly important. However, the spatial-temporal distribution of aircraft emissions and their byproducts span many orders of magnitude, as contrail development begins within seconds, but can spread to the kilometer-scale an ...

  • Low Temperature Autoignition of Conventional Jet Fuels and Surrogate Jet Fuels With Targeted Properties in a Rapid Compression Machine
    Low Temperature Autoignition of Conventional Jet Fuels and Surrogate Jet Fuels With Targeted Properties in a Rapid Compression Machine
    Valco, Daniel J ;
    Min, Kyungwook
    2016-10-01 | PDF
    The autoignition characteristics of conventional jet fuels (category A) and alternative fuels with targeted properties (category C) are investigated using a rapid compression machine and the direct test chamber charge preparation approach. The category C fuels were purposefully built to anticipate special property variations that generally occur in ...
  • Designing Flightdeck Procedures
    Designing Flightdeck Procedures
    Mauro, Robert ;
    Barshi, Immanuel
    2016-09-07 | PDF
    Aviation professionals have long understood that having safe and effective standard operating procedures for flightcrews is vitally important for conducting safe and efficient operations. Failing to follow flightcrew procedures or having inadequate procedures is consistently cited as a major cause of airline accidents and incidents, and has been ci ...
  • FAA Center of Excellence Alternative Jet Fuels Environment Annual Technical Report 2016 For the Period October 1 2015 September 30 2016
    FAA Center of Excellence Alternative Jet Fuels & Environment : Annual Technical Report 2016 : For the Period October 1, 2015 - September 30, 2016
    ASCENT Aviation Sustainability Center
    2016-09-01 | PDF
    This report covers the period October 1, 2015 through September 30, 2016. The Center was established by the authority of FAA solicitation 13-C-AJFE-Solicitation. During that time the ASCENT team launched a new website, which can be viewed at https://ascent.aero/. The next meeting will be held September 26 - 27, 2017 at the Embassy Suites in Alexand ...
  • Effects of Nocturnal Air and Rail Traffic Noise on Sleep
    Effects of Nocturnal Air and Rail Traffic Noise on Sleep
    Müller, Uwe ;
    Elmenhorst, Eva-Maria
    2016-09-01 | PDF
    Undisturbed and sufficiently long sleep is a prerequisite for a healthy life as well as for the prevention of fatigue-induced accidents. Especially the increasing air and freight rail traffic is more and more shifted to shoulder and night-time hours due to missing capacity and infrastructure during daytime. Thus, the sleep of residents near airport ...
  • TASOPT Engine Model Development A PARTNER Project 48 Report
    TASOPT Engine Model Development: A PARTNER Project 48 Report
    Pantalone, Giulia ;
    Blanco, Elena de la Rosa
    2016-09-01 | PDF
    This report describes the development of a new engine weight surrogate model and High Pressure Compressor (HPC) polytropic efficiency correction for the propulsion module in the Transport Aircraft OPTtimization (TASOPT) code. The goal of this work is to improve the accuracy and applicability of TASOPT in conceptual design of advanced technology, hi ...
  • Project 23 Analytical Approach for Qualifying Noise from Advanced Operational Procedures
    Project 23 Analytical Approach for Qualifying Noise from Advanced Operational Procedures
    Morris, Philip J. ;
    Hansman, R. John
    2016-08-01 | PDF
    Noise analysis is one important component of environmental evaluation for new flight procedure design. Communities, airports, regulators. Currently, the Aviation Environmental Design Tool (AEDT) is the primary tools used to evaluate new procedures and traffic intensity levels for calculating noise impact footprints near airports. AEDT noise calcula ...
  • Pilot Sleep Study near Philadelphia International Airport ASCENT Project 17 Report
    Pilot Sleep Study near Philadelphia International Airport — ASCENT Project 17 Report
    Basner, Mathias ;
    McGuire, Sarah
    2016-08-01 | PDF
    New field studies need to be conducted in the US to acquire current data relative to varying degrees of noise exposure to provide information on the effect of noise on sleep. As studies may need to investigate samples around multiple airports it will not be possible to use polysomnography to monitor sleep, as it has a high methodological cost. Inst ...
