THE RAINBOW OPTICAL LANDING AID.
Abstract
The report describes the Rainbow Optical Landing Aid and contains a mathematical analysis of the pilot-aircraftRainbow-geometry loop. The analysis underscores the salient characteristics of the Rainbow display which lead to precise, easily controlled landings. The Rainbow Optical Landing Aid was developed to provide the pilot with quickened glide path information by means of a colorsequence coded signal. A red-white-blue sequence tells the pilot to increase his sink rate; a red-blue-white sequence indicates that a smaller sink rate is required. A steady green informs the pilot that he is within =0.1 degree of glide path. Designed for location on the carrier deck, the Rainbow is strictly an optical-geometrical system requiring no electronics or external inputs. The experimental unit has been used at ranges up to 3.5 miles in bright sunlight, weighs less than 50 pounds, and cost less than $1,000. (Author)
