Based on the aerodynamic mechanism of the influence of ground effects on aircraft near ground flight,a longitudinal small disturbance equation is established by taking the motions on the gliding line of ship-based aircraft FCLP training as the reference,in which the ground effect is transformed into disturbance input,and the errors caused by ground effects in FCLP training are simulated and analyzed.Combined with the control characteristics of pilots in this stage,measures to reduce the influence of ground effects are discussed.This paper has reference significance for precise and safe ship-based flight training.
