Head Movements during Contour Flight

摘要

This head movement study was conducted to measure pilot head rotational movements during contour flights. The head movement data were collected from five subjects as each flew a modified UH-1M over a 15-mile contour course. The subject pilots also were required to visually search for an 'enemy' aircraft while flying the contour course. A helmet-mounted sight was used to measure the pilots' head movements. The head position data indicate the pilots looked forward most of the time, even though the scenario required a broad range of head movements. The data also suggest pure head-neck movements without torso participation. The head velocity data indicate symmetrical azimuth and elevation head movement components. Approximately 97 percent of the head movements were equal to or less than 120 deg/sec, although some movements exceeded 200 deg/sec.
