Effects of in-flight field-of-view restriction on rotorcraft pilot head movement

摘要: The work reported in this paper examines the effect of restricting visual field-of-view (FOV) on rotorcraft pilot head movement. To simulate FOVs current and future helmet mounted displays (HMDs) used for night vision pilotage, a FOV restrictor was attached to helmets test subject pilots. limited horizontal 100, 80, 60, 40, 20 degrees. Ten pilots executed set low altitude flight maneuvers an instrumented NAH-1S helicopter at NASA Crows' Landing Airfield Head movement measured with IR tracker those who flew rear seat by video camera front seat. Test data indicated that responded restriction sin changing their pattern movement, both azimuth elevation. These compensation strategies change as decreases vary from pilot. results paper, conjunction referenced outlining effects performance, handling qualities, cue ratings, give visionic system designers users predictive information workload performance.
