COMPARISON OF PERCEPTUAL WORK LOAD IN FLYING STANDARD INSTRUMENTATION AND THE CONTACT ANALOG VERTICAL DISPLAY
BELL HELICOPTER TEXTRON INC FORT WORTH TX
Pagination or Media Count:
The study reported in this document was an experimental approach to the comparison of visual free time that results in the pilot task when flying standard instruments and when flying the contact analog vertical display. The investigation was conducted under the direction of the Joint Army Navy Aircraft Instrumentation Research Program and funded under ONR Contract Nonr-167000. The standard instrumentation used in the study was an instrument panel composed of an airspeed indicator, an altimeter, a compass, an attitude indicator, a rate of climb meter, and a cross pointer position indicator. The contact analog vertical display investigated was built to BellJANA IR specifications by the Norden Division of United Aircraft Corporation for the JANAIR program. The task, performed in the Bell Helicopter Company dynamic flight simulator, required pilot Ss to fly a command altitude, heading, course, and airspeed. This was performed with both flight display systems. In addition, the pilot was required to read digits which were programed to appear on a separate display at varying rates. An index of the visual time available was obtained by the ability to read these digits in addition to performing the flight task.
