The invention provides an error analysis method for a semi-physical simulation system of an aircraft. On the basis of mathematical equations of a flight control system of the aircraft, the transfer function of a two-axis turntable and the transfer function of a three-axis turntable, and with the simultaneous aircraft and target relative kinematic equation and proportional guidance equation, mean and covariance equations are established based on the covariance analysis description function method, and the errors of the semi-physical simulation system of the aircraft are solved using the mean and covariance equations. The problem that the calculation error of the mathematical equations of the flight control system of the aircraft is not included in the existing method of missiles and other hardware-in-the-loop simulation system errors is solved. The errors obtained by the invention include the calculation errors of the mathematical equations of the flight control system, and can be usedto reveal abnormal phenom
