Safety analysis of airborne weather radar based on failure mode, effects and criticality Analysis

摘要：

The safety of the Airborne Weather Radar (WXR) will directly affect the safety of the whole aircraft and the flight.Taking the WXR as an illustrative system, the Failure Modes, the Effect and the Criticality Analysis (FMECA) methods in the safety analysis of system are firstly investigated in this paper, and the criticality of each failure mode is estimated.Secondly, the criticality matrix is applied to classify the failure modes.At last, all the failure modes are ranked based on their criticality to find out the critical failure modes or components, which can offer some instructional advices to enhance the efficiency of the safety optimization of the system.
