ALTITUDE EVASION IN VISUAL COLLISION AVOIDANCE.
Abstract
Findings of a program of studies and experiments conducted to determine ways to increase the col lision-avoidance capabilities of VFR aviation have implications for possible air traffic rule changes. Principally, a change in the evasion rule for converging courses appears indicated. VFR collision-avoidance depends on early detec tion and timely determination of the range and relative altitude of the other aircraft. Pilots' ability to estimate range is good and can be im proved by training. Altitude estimates are not as accurate, and training has no consistent ef fect. For night flight, an altitude-coded air craft exterior light system can effectively pro vide relative-altitude and climb/descent infor mation; pilots have quickly and accurately learned such a system. Such information could be utilized to formulate altitudinal evasion rules which pilots could use more readily than the present rules based on horizontal evasion. (Author)
