Abstract : A mathematical model for predicting the pilot rating of a fighter aircraft in a precision heading task is described. The model includes the lateral-directional aircraft equations of motion, a stochastic gust model, a pilot model with four free pilot parameters, and a pilot rating expression that is a function of rms heading angle, rms yaw rate, and rms roll rate. The pilot gains and lead time constants are selected to minimize the pilot rating expression. The resulting minimum is used to compute a heading paper pilot rating. The heading paper pilot rating was computed for 32 flight conditions at different gust intensities for the F-5 and A-7 aircraft. Heading paper pilot ratings agree well with the actual ratings for the F-5, but are low for the A-7. In addition, there is good correlation between computed and actual rms heading angle, rms yaw rate, and rms slideslip. (Author)
