  • Development of Airport Active Runway Vehicle Lighting
    Development of Airport Active Runway Vehicle Lighting
    Patterson, James W.
    2004-05-01 | PDF
    Runway incursions are a leading cause of airport ground accidents and usually result from the presence of unauthorized ground vehicles within the active runway area. In many cases, air traffic control personnel can become confused by the numerous flashing lights and various colors of lights on vehicles operating on the airport and because of this, ...
  • Behavior of Bromotrifluoropropene and Pentafluoroethane When Subjected to a Simulated Aerosol Can Explosion
    Behavior of Bromotrifluoropropene and Pentafluoroethane When Subjected to a Simulated Aerosol Can Explosion
    Reinhardt, John W.
    2004-05-01 | PDF
    This technical note presents the data from simulated aerosol can explosion tests while using bromotrifluoropropene (BTP) and pentafluoroethane (HFC-125) as fire suppression agents for aircraft cargo compartments. These explosion tests were conducted at below inert volumetric concentrations to determine the agent’s explosion attenuation performance. ...
  • Effects of Collocation and Reduced Lateral Separation Standards in the New York integrated Control Complex
    Effects of Collocation and Reduced Lateral Separation Standards in the New York integrated Control Complex
    Truitt, Todd R ;
    McAnulty, D. Michael
    2004-03-01 | PDF
    The authors used a high fidelity, human-in-the-loop simulation in two experiments examining the concept of the New York Integrated Control Complex (NYICC). The first experiment examined the potential effects of collocation alone and collocation with expanded terminal separation standards on the arrival traffic flow into Newark. The second experimen ...
  • The Effect of Voice Communications Latency in High Density CommunicationsIntensive Airspace Phase 2 Flight Deck Perspective and Comparison of Analog and Digital Systems
    The Effect of Voice Communications Latency in High Density, Communications-Intensive Airspace Phase 2: Flight Deck Perspective and Comparison of Analog and Digital Systems
    Zingale, Carolina ;
    McAnulty, D. Michael
    2003-11-01 | PDF
    The FAA Next Generation Air-Ground Communications (NEXCOM) program plans to replace the aging analog air traffic communications system with a Very High Frequency (VHF) Digital Link Mode 3 (VDL3) system. VDL3 provides increased channel capacity, can transmit both voice and data, and compensates for known limitations in the analog system through feat ...
  • Auditory Alarms in an Airway Facilities Environment
    Auditory Alarms in an Airway Facilities Environment
    Ahlstrom, Vicki ;
    Panjwani, Gulshan
    2003-11-01 | PDF
    This report describes a study on auditory alarms in Airway Facilities (AF). There are two parts of the study. The first part of the study presents a baseline of current auditory alarms and the current acoustical environment at AF operational sites. A research team from the William J. Hughes Technical Center visited Service Operations Centers at sev ...
  • Study of Bird Ingestions Into Aircraft Turbine Engines December 1968December 1999
    Study of Bird Ingestions Into Aircraft Turbine Engines (December 1968-December 1999)
    Lewis, Chester M. ;
    Tritz, Terrance G.
    2003-09-01 | PDF
    The Canada goose population has been on the increase, causing concern over the possibility of increased dual-engine ingestions and potential dual-engine power loss. This report summarizes a review of the historical data concerning bird ingestions in turbofan engines and includes extrapolations of the data needed to forecast future dual-engine inges ...
  • Limiting Oxygen Concentration Required to Inert Jet Fuel Vapors Existing at Reduced Fuel Tank Pressures
    Limiting Oxygen Concentration Required to Inert Jet Fuel Vapors Existing at Reduced Fuel Tank Pressures
    Summer, Steven M.
    2003-08-01 | PDF
    This report discusses experiments to determine the reduction in oxygen concentration required to prevent a fuel tank explosion. A simulated aircraft fuel tank containing JP-8 fuel of an amount equivalent to a mass loading of approximately 4.5 kg/m3 was used to determine the limiting oxygen concentration (LOC) at pressures corresponding to altitudes ...
  • A Description and Analysis of the FAA Onboard Oxygen Analysis System
    A Description and Analysis of the FAA Onboard Oxygen Analysis System
    Burns, Michael ;
    Cavage, William M.
    2003-07-01 | PDF
    The Federal Aviation Administration (FAA) is planning a series of ground and flight tests with Airbus to prove the concept of a simplified fuel tank inerting system, which has been developed by the FAA. The FAA has also developed an onboard oxygen analysis system to measure the oxygen concentration in the aircraft fuel tank during the testing. To h ...
  • Human Factors Design Standard for Acquisition of CommercialofftheShelf Subsystems NonDevelopmental Items and Developmental Systems
    Human Factors Design Standard for Acquisition of Commercial-off-the-Shelf Subsystems, Non-Developmental Items, and Developmental Systems
    Ahlstrom, Vicki ;
    Longo, Kelly
    2003-05-01 | PDF
    The Human Factors Design Standard (HFDS) provides reference information to assist in the selection, analysis, design, development, and evaluation of new and modified Federal Aviation Administration (FAA) systems and equipment. This document is based largely on the 1996 Human Factors Design Guide (HFDG) produced by the FAA in 1996. It converts the o ...

    Ground Tests of Aircraft Flight Deck Smoke Penetration Resistance
    Blake, David
    2003-04-01 | PDF
    This report documents a series of tests to determine the amount of positive pressure differential between the flight deck and surrounding areas necessary to prevent smoke from penetrating into the flight deck. The testing also explored methods to demonstrate the effectiveness of those ventilation conditions. The tests were conducted on the ground i ...

    Paint markings on runways, taxiways, and ramps play an important role in preventing runway incursions. Paint markings, however, deteriorate in terms of their conspicuity and must be replaced over time. Presently, the conspicuity is determined by visual inspections of segments of these markings, but the validity of these inspections cannot always be ...
