Abstract:

An evaluation was conducted on an annunciator display designed to be readable in direct sunlight. The color of the luminous legend was aviation red. The type of display evaluated is currently being used in commercial and military aircraft. Photometric and spectroradiometric measurements were taken in dark ambient lighting and in solar ambient lighting direct sunlight conditions. The red luminous legend was confortably readable in direct sunlight even though the luminance contrast was below the 50 percent recommended by MIL-STD-1472B.
