Abstract:

Three different spectral distributions of cockpit display lighting were investigated as to their effects on dark adaptation and visual acuity during night flight. These distributions were instrument and panel lighting red, tungsten clear white, and Air Force lunar blue-white. Cockpit-lighting brightness photopic luminance, color and color combinations with the addition of indicator lights were controlled, and effects on dark adaptation and distant visual acuity outside the cockpit were measured. Interactions among lighting colors, photopic and scotopic visual acuities, and luminance thresholds for objects of different sizes were shown. Results were discussed in relation to the literature on dark adaptation and night vision in flight. Author
