The report summarizes that portion of a research program on visual mid-air collision avoidance techniques which deals with the feasibility and efficacy of various optical aids. Literature relevant to promising optical aids is reviewed, including that on sunglasses, visors, goggles, telescopes, binoculars, periscopes, sighting levels, collimated reticles, rear-view mirrors, and closed-circuit television. No one optical aid can provide adequate assistance over the entire range of visual conditions found in flight. Sunglasses provide a number of advantages including the reduction of glare and the immediate and cumulative effects of exposure to high brightness levels. Telescopes and binoculars can assist in making inferences about detected aircraft, but will not materially assist in searching. Rear vision may be increased by mirrors, but mirror vibrations and vibrations acting upon the pilot degrade visual performance.
