CONTRAST SENSITIVITY PREDICTS PILOTS' PERFORMANCE IN AIRCRAFT SIMULATORS

Abstract
Contrast sensitivity was better than visual acuity for predicting a pilot''s ability to detect a small, semi-isolated air-to-ground target. Eleven instructor pilots had their acuity measured by both conventional and contrast sensitivity methods. Scotopic contrast sensitivity showed the highest correlation with slant detection range (0.83). Conventionally determined visual acuity proved to be a poor predictor of a pilot''s ability to detect a small low contrast target.
