The self-repairing flight control system maintenance diagnosis information source is the fault detection, but its shortcoming is that the real-time control and the detection accuracy are difficult to coordinate.The direct self-repairing flight control system cancels the fault detection module, but needs to carry on the control system breakdown confirmation. In this paper, the compensation information of direct self-repairing flight control system is used to train the neural network to identify the fault and identify the secondary faults, so that the fault recognition algorithm is in the real-time level of the alarm, so as to improve the accuracy of the verification.The fault self-healing flight simulation results show that, The neural network fault identification method is effective.This flight simulation system has passed the verification of the self-repairing flight simulation platform, which provides a new idea for the flight maintenance diagnostic information acquisition and driver alarm
