| Abstract: | The reliability of Fly-By-Wire Flight Control System is been analyzed, and the engineering methods of reliability design are introduced.The model eliminating risk by pilot because of the failure of flight control system is established,and two methods calculating the conditional probability of eliminating risk are presented.Based on the study of the pilot-aircraft system,flying security model is built to apply Markov chains,and the calculation method of flying security evaluation for the control system failure is put forward.At last,an example taking account of horizontal sensor fault is given to evaluate flying security of a plane. |
