A STUDY OF A PILOT'S ABILITY TO CONTROL DURING SIMULATED STABILITY AUGMENTATION SYSTEM FAILURES

摘要

The results presented show the effects of failure of a stability augmentation system on the pilot's ability to control while engaged in a simple tracking task. The results of failures simulated in a fixed and moving-cab centrifuge suggest that moving cockpit flight simulators provide a more realistic evaluation of the transient effects of stability augmenter failures. In the present study, simulator motions generally interfered with the ability of the pilots to adapt to the failures. A pencil-type side-arm controller proved easier to use than a conventional center stick in coping with pitch damper failures at the higher short period frequencies. The use of simple pilot models in the analysis and prediction of the transient effects of stability augmenter failures provided encouraging results.
