Abstract: A safety assessment method based on semi-physical simulation was proposed to assess airborne software safety and develop safety control technique in multi-factor coupled complex flight situation. A thought using flight simulator test to assessment software safety was introduced. Operation procedure of the safety assessment method was designed. Simulator’s main mathematics model was established. Referencing biological theory, mechanism of software fault induce aircraft accident was analyzed. Finally, embedded software of stability augmentation system was assessed safety. The result demonstrates the method proposed is feasible in project practice. The method can be used to reduce aircraft risk that induced by the airborne software fault in multi-factor coupled complex flight situation, and then improve the safety of airborne software.
