The reliability level of flight control system directly affects the flight safety and the mission realization of the aircraft. With the surging complexity of flight control system, the traditional methods are more time-consuming and error-prone to support the mission reliability analysis. In this paper, a new mission reliability analysis method of flight control system based on AltaRica language is proposed. With early functional and architectural design information, a comprehensive model of system normal function and fault behavior is built based on AltaRica language. By semantic mapping, the comprehensive model could be automatically transformed to fault tree models, which describe the logical relation of mission and fault modes, to implement reliability qualitative analysis and quantitative evaluation with all the failure mode distribution information. At the end of this paper, a typical flight control system comprehensive model is built as an example to execute the corresponding analysis, so as to prove the availability and simplicity of the reliability analysis method, which improves the accuracy and efficiency of mission reliability analysis.
