Selection of Wiring Environment and Failure Rate Comparison Analysis in Aircraft Wiring Risk Assessment

There has been a greater understanding of the importance of EWIS in aircraft safety in recent years. The expert opinion, a formal pair comparison experiment is applied to acquire wiring failure rate data. The selection of wiring environment and failure rate comparison is critical in doing the pair comparison experiment. Combined with a certain aircraft model, this paper studies the principles to choose wiring environment and the methods of failure rate comparison for aircraft risk assessment.
