Abstract : Evaluation was made of the pilot's ability to land, takeoff, hover and navigate a helicopter using television for visual contact with the ground. The effects of two experimental variables were investigated. These were the position of the forward looking TV camera (on the landing skid as compared to being at the pilot's eye level) and camera movement (fixed as against movable in pitch). Evaluation of the operations was also made under VFR as a control procedure. Measurement was made of airspeed, altitude, heading fore-aft and lateral position errors. In general, the TV condition did not compare favorably with the VFR situation in precision of control but the operations were usually successful and always safe. It was found that camera mobility facilitated the landings but was of less consequence for the other operations. It was concluded that TV, while useful, will not prove completely adequate for night flights. It is recommended that it be used in concert with the contact analog vertical display. (Author)
