Abstract:

An investigation was made of the ability of ground observers, unaided by optical or electronic devices, to detect visually each of six reconnaissance aircraft. Calculations are made for a variety of conditions, in altitudes, speeds, and visibilities. Among several conclusions are 1 the probability of visual detection falls off rapidly as aircraft altitude is decreased below 2000 ft 2 increasing speed is an effective way to reduce detectability 3 contrast is a critical factor in determining detectability but is difficult to predict or control.
