JANAIR: JOINT ARMY-NAVY AIRCRAFT INSTRUMENTATION RESEARCH, INVESTIGATION OF AUDITORY DISPLAYS.
Abstract
A feasibility study was performed to examine the use of acoustic displays in aircraft longitudinal control. Emphasis was given to carrier landing. Initial experiments examined control compatibility of certain acoustic codes, together with their information carrying capability in representative noise. Frequency level and modulation characteristics were explored, together with compensatory and 'pursuit' characteristics. Specific codes were compared, in a major carrier landing simulation, against conventional visual display techniques. Display quickening was introduced and evaluated. A pulse-frequency modulated code at low relative signal level and high relative frequency characteristics, was developed and tested during simulation for speed-angle-of-attack through stick and throttle manipulation, were examined. Dual channel acoustic presentation combining speed-angleof-attack and height display were explored to a limited extent. Favorable conclusions were made concerning acoustic longitudinal control display. (Author)
