Abstract : The dynamic visual field of view was measured from the rear seat of the U. S. Army O-1A (Bird Dog) aircraft. Subjects from the 5 and 95 percentile level sitting eye heights were used to determine the changes in field of view when the short man occupied the front seat and the tall man the rear, and vice versa. Changes occurring as a result of using a cushion, sitting in a fixed position, or moving the extent of the seat harness were also measured. Recommendations are made concerning seat adjustment characteristics, rear window design, the availability of instruments to the Instructor Pilot in the rear seat, and the weather standards for dual VFR flight.
