A variable strategy pilot model for carrier landing approach was presented. The model was integrated by two components: a discontinuous component of the acquisition strategy for a large deviation of glide path and a continuous component of pursuit tracking strategy for a small deviation. The variable structure model was based on the sliding mode control theory to switch different control strategies of acquisition and pursuit tracking. Parameters of switching surface were extracted from literature of pilot training and pilot experience. The continuous component was constructed by classical models of pilot transfer functions and the parameters were evaluated in accordance with the crossover model theory. The simulation results of a carrier landing approach show that the model is of rationality and validity.
