N2 - The integrated avionics system are widely used in large advanced aircrafts, such as A380 and Boeing 787. A perfect deign of the avionics system is very important for the reliability and safety of the aircraft. There will be many faults in the design stage of the integrated avionics system. In order to develop a good system, we should manage its plentiful fault information. According to analyzing the fault information, the failure mechanism of the avionics system can be revealed, and then we can propose corrective actions in the design stage of the avionics system. However, at present the fault management information system is mainly focus on the hardware faults and it can't cover all the fault modes emerging in the avionics system design stage. For the integrated avionics is so complex that a lot of software are using in the system, there are software faults as many as hardware faults in the system. In addition, for the different subsystems are connected through switches, a fault occurring in one subsystem may make the other subsystem not work properly, so the faults in different subsystems may not be independent. For this reason, it is difficult to use classic FMEA method to analyze the modern comprehensive integrated avionics system. We propose a network FMEA method to manage the fault information of the avionics system. We regard the avionics system as a network, and then we can analyze the relationships of faults in different parts of the avionics system. Based on the network fault characteristics, the avionics system faults can be classified as hardware function fault, performance fault and process fault. In addition, according to statistical analysis, if we classify the faults of the avionics system as above, the fault cases management system can cover all the faults emerging in the avionics system design stage. The proposed fault case management system not only can help us analyze both the hardware faults and software faults in the avionics system, but also can help us find the relationships between different faults in different parts of the avionics system. At last, the engineers can improve the system according to the fault analysis results, and then the reliability and safety of the avionics system are improved.
