  • The effect of increased monitoring load on vigilance performance using a simulated radar display
    The effect of increased monitoring load on vigilance performance using a simulated radar display.
    Thackray, Richard I. ;
    Bailey, J. Powell
    1977-07-01 | PDF
    The present study examined the extent to which level of target density influences the ability to sustain attention to a complex monitoring task requiring only a detection response to simple stimulus change. The visual display was designed to approximate a futuristic, highly automated air traffic control radar display containing computer-generated a ...

    Rasmussen, P.G.
    1977-07-01 | PDF
    Readability data of alphanumeric characters that vary in figure-to- ground contrast ratio were obtained from 36 subjects; 12 subjects were placed in each of three age groups (20-25 yr, 40-45 yr, and 60-65 yr). Minimum illuminance required to identify all contrast combinations was determined at a viewing distance of 40 cm (15.7 in) under dim white a ...

  • Perceived orientation of a runway model in nonpilots during simulated night approaches to landing
    Perceived orientation of a runway model in nonpilots during simulated night approaches to landing.
    Mertens, Henry W.
    1977-07-01 | PDF
    Illusions due to reduced visual cues at night have long been cited as contributing to the dangerous tendency of pilots to fly too low during night landing approaches. The cue of motion parallax (a difference in rate of apparent movement of objects in the visual field) is frequently suggested as contributing to visual judgments of glide path but has ...

    Objective methods for developing indices of pilot workload.
    Chiles, W. Dean
    1977-07-01 | PDF
    This paper discusses the various types of objective methodologies that either have been or have the potential of being applied to the general problem of the measurement of pilot workload as it occurs on relatively short missions or mission phases. Selected studies that have dealt with the workload measurement problem or some similar problem are rev ...

    This study involved a census of 4,491 general aviation accident-involved airmen records for the year 1974 to obtain relevant occupation, age, exposure, and other epidemiologic profile information of a descriptive nature. Population comparison data for occupation, age, and exposure were obtained from a sample of 9,414 currently certified airmen medi ...
  • A study of effects of hyperthermia on large shorthaired male dogs a simulated air transport environmental stress
    A study of effects of hyperthermia on large, short-haired male dogs : a simulated air transport environmental stress.

    Higgins, E.A.
    1977-03-01 | PDF
    When dogs are shipped by air transport, they can encounter environmental temperatures as high as 130.0 F during the summer months. Heat- induced hyperthermia can be a major problem in dogs.To assess some aspects of the heat stress problem, 20 dogs were exposed to an ambient temperature of 130.0 F for 30 minutes--10 dogs at 15% relative humidity and ...

    Hoffman, S.M.
    1977-02-01 | PDF
    Data obtained from sleep logs maintained for a period of 5 weeks by 185 air traffic controllers indicate that on a weekly basis there is no significant difference in the amount of sleep obtained by controllers working the 2-2-1 rotation pattern and that obtained by those on the 5-day rotation pattern. Controllers working the 2-2-1 rotation pattern ...
