Abstract : A method for predicting the performance of the total pilot-vehicle system has been developed for the lateral dynamics of Class 4 airplanes. This method, which is based on pilot model theory and multiloop analysis, predicts tracking errors for command tracking tasks and also for attitude hold tracking tasks in turbulence. The predictions are in terms of root mean square time domain statistics and are obtained by means of a fully automated multiloop analysis performance prediction program available from the United States Air Force. Thus, system performance can be evaluated analytically in terms of familiar time domain root mean square statistics. The validity and accuracy of this method have been ascertained by means of moving base simulation on the Northrop Large-Amplitude Flight Simulator operating in five-degree-of-freedom motion.
