Abstract : Subjects operated three different sets of switches as they were flown through 0-G trajectories in a C-131B aircraft. Push-button, toggle, and rotary switches were each paired with a master push-button switch to form the three sets used to turn an indicator light on and off. The subjects were instructed to perform the task as fast as possible by alternateACTUATION OF THE TWO SWITCHES OF EACH SET. Each subject also performed in straight and level flight with each set of switches for control data. Performance data, along with aircraft accelerative forces in three dimensions, was recorded on a high-speed oscillograph. Small decrements were found in speed of operation of all three sets of switches in the 0-G environment in comparison with performance at 1-G. The toggle switch set showed the greatest decrement, the rotary switch set the least decrement. The push-button switch set was operated most rapidly in both 1-G and 0-G conditions. (Author)
