Description
Summary:Review of the literature in aviation and in vision, and consideration of photometric methods available, raise a number of fundamental questions about cockpit lighting. Dark adaptation and acuity must be examined in relation to the total cockpit light flux, the ambient illumination outside the cockpit, and the spectral composition of the light flux. Furthermore, the aircraft mission requirements must be incorporated into design decisions. The program of research recommended has a character consistent with that proposed by Bartelt, Twist and Lazo (1966). Photopic and scotopic luminance, photometric and radiometric methods, color coding and contrast, and acuity at low luminances are reviewed. Analytic methods are described, and areas requiring fundamental human factors research are indicated. (Author) See also part 2, AD-678 560.
