If electronic devices should fail, pilot of spacecraft would have to depend upon direct visual sensing of important parameters, such as range and range rate, to complete his mission; cue for judgments of changes in range might be derived from associated changes in brightness of beacon light located on vehicle with which pilot was attempting to rendezvous; this report describes study of effects, on such judgments, of four variables -- beacon flash rate, beacon "on" time, beacon intensity, and rate of vehicle closure.
