Abstract: Electro-mechanical actuation system failure often leads to disastrous consequences. Using a top-down design idea, this paper proposes electro-mechanical actuation system analysis approach of the impact on flight safety. This paper combines electro-mechanical actuation system failure mode and the flight control system failure model together. It obtains failure modes and effects analysis of electro-mechanical actuation system. It uses the Monte-Carlo method to obtain the electromechanical actuation system failure probability. Application of extreme value theory is used to calculate the flight safety probability. Simulation experiments demonstrate that this method can be used as the basis for security monitoring.
