摘要

To quantitatively evaluate the flight test risk after a flight control system failure, a flight risk assessment method is proposed. The pilot-aircraft-environment model and flight control system failure model are developed. Based on the limitations of the critical parameters and Monte Carlo simulations, the classification method for the failure effect level and the flight test risk assessment method are proposed. Finally, one-side aileron jam failure is taken as an example to demonstrate the method.
