Abstract

Our recent research has shown that contrast sensitivity, not visual acuity, can predict a pilot's ability to detect an air-to-ground target in a flight simulator. Here we report a further study that shows a similar predictive power under actual field conditions. Eighty-four Air Force pilots, seated at the end of a runway, typically in groups of ten per week, reported the detection of an approaching T-39 jet aircraft under visibility conditions varying from 0.5 to over 15 miles for 10 field trials. The pilots' detection ranges were correlated with their individual contrast sensitivities and standard visual acuities. Contrast sensitivity, not visual acuity, was found to be a good predictor of detection range. These results have strong implications for the creation of performance-related vision standards.
