Abstract : The AH-64A employs an integrated helmet and display sight subsystem which presents night vision system and flight data to the pilot's right eye. Velocity.vector and acceleration cues tell the pilot when the aircraft is accelerating, its speed, and vector. A 6 kt cue is used for hovering; a 60 kt cue for transition. A single 20 kt cue was proposed for the AH-64D. The requirement was dropped, but the question remained as to whether the 20 kt cue provided any advantage. The experiment was conducted to answer this question. Ten AH-64A pilots performed a mission consisting of seven Aircrew Training Manual (ATM) tasks, under 1-day and 2-night conditions (6/60 kt and 20/60 kt cues) in the simulator training research advanced testbed for aviation (STRATA). The STRATA copilot-gunner station was used with a rear-projection display. Of 210 task events, 209 met ATM standards. Performance across all tasks was better in the 6/60 than in the 20/60 condition (%%.04, two-tailed). Performance on stationary hover reached significance (2%.05) and approached significance for three other hovering tasks. Results supported retention of the 6 and 60 kt cues.
