  • Effect of Free Flight Conditions on Controller Performance Workload and Situation Awareness
    Effect of Free Flight Conditions on Controller Performance, Workload, and Situation Awareness
    Endsley, Mica R ;
    Mogford, Richard H
    1997-12-01 | PDF
    Free flight represents a major change in the way that aircraft are handled in the National Airspace System. It has the potential to significantly increase airspace utilization and, by doing so, improve aircraft throughput. The degree to which these objectives can be met without compromising aircraft safety will depend on appropriate changes in the ...

  • Human Factors Evaluation of Vocoders for Air Traffic Control Environments Phase II ATC Simulation
    Human Factors Evaluation of Vocoders for Air Traffic Control Environments, Phase II: ATC Simulation
    Sollenberger, Randy L ;
    La Due, James
    1997-12-01 | PDF
    Vocoders offer a potential solution to radio congestion by digitizing human speech and compressing the signal to achieve low bandwidth voice transmissions. A reduction in bandwidth will allow the addition of more communication channels to the system and reduce radio congestion. This air traffic control simulation study is the second phase of a rese ...
  • Heating Comparison of Radial and BiasPly Tires on a B727 Aircraft
    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
    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 ...
