A flight test was conducted comparing a forward field of view with a combination forward-vertical field of view for visually acquiring tactical targets in a densely foliated environment. The test, using a B-50D aircraft, was conducted in the Panama Canal Zone under conditions of poor visibility overcast, rain showers. Ten subjects, tested individually, used the forward field of view. Nine different subjects used the combination forward-vertical field of view. The 11 tactical targets used bridges, huts, vehicles, etc. varied in amount of cover and offset from the flight path. All targets were visible under both fields of view. There were significant differences, both statistical and operational, in the number of targets acquired with the two fields of view. The forward-vertical field of view was superior in terms of the 11 targets detected average 7.67 vs. 5.00 in the acquisition of the 7 offset targets average 2.8 vs. 1.6 for 4 difficult targets average 3.6 vs. 2.0 and for the 4 zero to small offset targets average 4.9 vs. 3.9. These findings are discussed and recommendations are made. Author
