The invention provides an airplane deviation characteristic prediction method with a control system, and the method comprises the steps: building an airplane deviation prediction criterion according to a deviation motion mechanism, a system stability theory of an airplane kinetic equation, and a flight control system principle, wherein the aircraft deviation prediction criterion comprises a dynamic yaw divergence parameter criterion and a lateral control deviation parameter criterion; coupling the control influence of transverse course stability augmentation, transverse course cross-linking coupling and a multi-control-surface control distribution strategy contained in a flight control system into an airplane deviation prediction criterion; and carrying out deviation characteristic prediction evaluation by utilizing the coupled aircraft deviation characteristic prediction criterion with the control system. According to the method provided by the invention, course stability augmentation, transverse course cross-linking coupling and multi-manipulation control distribution strategies in the flight control law are expanded to the aircraft deviation characteristic criterion, and the technical basis is provided for the aircraft high-attack-angle control strategy by introducing the analytical relationship between the deviation criterion and the control system, so that the aircraft safety is effectively ensured, and the risk is reduced.
