Abstract : The development of target tracking weaponry on the Army's Advanced Attack Helicopter (AAH) allows directional tracking with FLIR imagery at large angles from the longitudinal axis. A flight simulation using a helmet mounted display w as conducted to quantify head tracking performance and to identify off-axis tracking limits for the aircraft's Pilot Night Vision Sensor. The experimental parameters included varying flight trajectories (hover, rectilinear, and curvilinear paths) and the target velocities and ranges. This paper details the design efforts in creating tracking scenarios in the simulator and the head tracking algorithms used to generate command profiles for perfect line of sight tracking performance. Confidence in the algorithms for tracking data calculations was essential to experimental conclusions on human tracking behavior and performance. The successful attempt to replicate the night vision system of the AAH is also discussed. (Author)
