Abstract : The FP-50 flight display unit is designed to provide a visual display of aircraft attitude and certain tactical information to the pilot. A cathode ray tube (CRT) is used to display the information. It was anticipated the FP-50 display lighting in the cockpit would affect the pilot's outside visual performance during night flight. The report summarizes both photometric measures and human factors experiments on the FP-50 with pilot subjects. Results indicated that the white light of the display had negligible effects on dark adaptation and visual acuity when operated at suitable low-level brightness for night flight. It was discovered, however, filters enhanced contrast of the display by three or four times at these low luminances. (Author)
