Abstract

Investigations were conducted to determine what size (visual angle) of objects and where in the forward visual field objects should be placed to provide maximum effectiveness in a simple altitude control task. Two experiments placed between 7 and 9 degrees below the horizon enabled significantly better altitude control and induced the least tendency to drift in altitude. The two experiments investigated targets ranging from 2 to 20 degrees in horizontal visual angle. This variable did not prove to significantly affect altitude control or altitude drift. Subject variance was significant in both experiments.
