Abstract : A mathematical model for predicting the pilot rating of an aircraft in a pitch tracking task is described. The model includes the longitudinal-directional aircraft equations of motion, a stochastic gust model, a pilot model with two free parameters, and a pilot rating expression that is a function of rms pitch angle, rms pitch rate, and the pilot lead time constant. The pilot parameters are then adjusted to provide at least a 20% stability margin, and the adjusted pilot parameters are used to compute a Flypaper Pilot rating of the aircraft/gust configuration. The Flypaper Pilot rating was computed for 32 aircraft/gust configurations. A range of actual ratings from 2 to 8 was encountered and the Flypaper Pilot ratings agree quite well with the actual ratings. (Author)
