SIMULATOR MOTION EFFECTS ON A PILOT'S ABILITY TO PERFORM A PRECISE LONGITUDINAL FLYING TASK

摘要

A program was conducted on the NASA normal acceleration and pitch (NAP) simulator to determine the effect that body-motion cues have on the pilot's ability to perform a precision close-coupled tracking task. These tests were conducted with heavy stick-force gradient and with zero-stick- force gradient over a range of longitudinal stability conditions. Pilots controlled the simulator from both a fixed and a moving cockpit.nThe results indicate that there-was improvement in pilot perform¬ance due/ to motion dues over the stability range tested. The motion cues appreciably improved the performance of both pilots when the feel forces were absent. The pilots always preferred to be supplied with motion cues. In the absence of feel forces, confusion was exhibited by one pilot as to the proper direction to execute control when bodily-motion cues were not provided.
