Data were obtained from a fixed base simulation of VTOL aircraft in the lateral hover mode and used to develop a technique for predicting lateral hover flying qualities. The task for the simulation was to maintain position in the presence of lateral gusts. Root-mean-square aircraft state and pilot input data were obtained and correlated with Cooper-Harper Pilot Ratings. A mathematical model for predicting the pilot rating of VTOL aircraft in lateral hover is developed. This model includes the lateral hover aircraft equations of motion a stochastic gust model a linear pilot model and a pilot rating expression that is a function of rms position error, rms lateral velocity, rms roll rate, and pilot lead terms.
