Abstract:

The study objectives were to investigate effects of a Head-Up Display on a pilots ability to see runway lights in fog. Methods of evaluation of the Head-Up Display concept under low visibility conditions were developed. Various physical parameters were measured. Luminance of the Head-Up Display, cockpit interior, and external scent were measured with a Pritchard Telephotometer at 30 minute arc intervals. The scene was examined for glare sources and analyzed for the adaptation level which could be expected by a pilot. Under normal operating conditions with the visibility range 1200 ft, day or night, no glare sources were identified and adaptation levels were reasonable. It was concluded from these objective measurements that the Head-Up Display unit tested would not adversely affect pilots ability to see runway lights in fog. Author
