    Heating Comparison of Radial and Bias-Ply Tires on a B-727 Aircraft
    Cavage, William M.
    1997-11-01 | PDF
    Aircraft taxi tests were conducted to compare the heating correlation of radial and bias-ply tires. The tires were tested on a Boeing 727-200QC, owned and operated by the Federal Aviation Administration (FAA) for the purpose of aircraft safety research. The aircraft was taxied at two different tire loads, at three different speeds, and for a given ...

    Human Factors Evaluation of Vocoders for Air Traffic Control Environments, Phase I: Field Evaluation
    LaDue, James ;
    Sollenberger, Randy L
    1997-09-01 | PDF
    Communication congestion is a major problem facing the air traffic control system. Vocoders offer a potential solution to this problem by compressing a digitized human speech signal to achieve low bandwidth voice transmissions. Air traffic controllers and pilots must find new systems usable and acceptable before the FAA authorizes implementation. T ...

    Several dual color (red/blue) edge lighting configurations used to define the pre-threshold and post-runway end segments of declared distance runways were evaluated at four different airports. At three airports, Binghamton Regional Airport, Baltimore-Washington Airport, and Atlantic City International Airport, the lighting configurations were in ac ...
  • FollowOn Friction Testing of RetroReflective Glass Beads
    Follow-On Friction Testing of Retro-Reflective Glass Beads
    Bagot, Keith
    1996-07-01 | PDF
    In 1993 and 1994 the FAA Technical Center conducted an evaluation of retro-reflective beads in airport pavement markings. That study proved that the addition of glass beads greatly enhanced the conspicuity of the surface markings. In the study the beaded stripes had a silica (sand) friction enhancement added to the paint. A concern arose as to ·the ...
  • Estimated Detection System False Alarms from Cargo Compartment Fire Extinguisher Discharge Statistics
    Estimated Detection System False Alarms from Cargo Compartment Fire Extinguisher Discharge Statistics
    Eklund, Thor I.
    1996-05-01 | PDF
    Data on aircraft fleet service difficulties between 1988 and 1990 were used to estimate fire detector false alarms in the domestic commercial jet fleet. For Class C cargo compartments, data on fleet composition and utilization were used to establish false alarm rates using two levels of analytical detail. False alarms for engine nacelles, auxiliary ...
  • JAA Airport Lighting System Requirements Simulator Evaluation

    Katz, Eric S.
    1996-04-01 | PDF
    The European Joint Aviation Authority (JAA) introduced its Joint Airworthiness Requirements for Operations (JAR-OPSl) in April 1995. In general, the airport lighting system requirements and associated operating minima authorized by the JAA for use during low-visibility takeoff and landing operations are lower than that used by the United States (U. ...
  • Continued Fireworthiness of Aircraft Interior Materials
    Continued Fireworthiness of Aircraft Interior Materials
    Cahill, Patricia
    1996-04-01 | PDF
    Vertical flammability tests specified by the Federal Aviation Administration (FAA) under FAR 25.853 were performed on a variety of interior materials removed from surplus DC-IO, B-707, and B-747 aircraft in order to verify their continued fireworthiness. It was determined that the large majority of materials were in conformance with the test requir ...
  • Aircraft Cabin Smoke Control with ConvergingDiverging Nozzles

    Eklund, Thor I.
    1996-04-01 | PDF
    The characteristics of converging-diverging nozzles are compared to those of converging nozzles for use in aircraft cabin smoke control. The peak flow flight regimes for the two different nozzles are compared by means of test data taken on a Boeing 757. The converging-diverging nozzle is shown as capable of maintaining peak volumetric flow over a w ...

    Evaluation of L-804 Elevated Runway Guard Light Fixtures
    Katz, Eric S.
    1996-03-01 | PDF
    The number of inadvertent runway incursions has grown during recent years, increasing the importance of protective visual guidance systems for incursion prevention. One such visual system is the L-804 elevated runway guard light fixture. Also known as a wig-wag light, these fixtures contain two alternately flashing yellow lights and are used to hel ...
  • Tire Test Correlation Radial Versus BiasPly Tires

    Stein, Earl S.
    1995-09-01 | PDF
    Air traffic control (ATC) is conducted by men and women of the Federal Aviation Administration's (FAA) air traffic service. Controllers do an excellent job of keeping aircraft separated and safe. However, they do make mistakes. Many of these errors are caused by the limitations of working memory, which controllers continuously use to maintain situa ...
