Abstract:

Zonal safety analysis (ZSA) is important to system safety analysis, and it is especially required for the safety design of large airplanes now being developed in China. As the present ZSA method is not specific or definite enough to implement, an improved ZSA method was proposed in this paper. It first made definite how the results of FMEA and FMECA are input to ZSA in the traditional operation process, which made the method more practicable in the field of engineering.
