The avionics system is one of the most vital factors which can affect performance of modern planes and it is very important for research of the fault prognostic and health management(PHM)technology to ensure the safety of the avionics sys?tem and the whole plane. According to the integrated modular development tendency of the avionics system,a PHM system is proposed for open type and modular architecture. The hierarchical function allocation of avionics system is utilized in this paper to design the architecture of the PHM system and the related technology detail by the analysis of the critical subsystems. The analysis result shows that the designed PHM system can meet the demands of standardization,hierarchy,modularization and openness of avionic systems.
