Safety Analysis of Airborne Weather Radar Based on Fault- tree
摘要
Abstract
The safety of airborne weather radar (WXR) directly affects the safety of the whole aircraft and the flight. Therefore, based on the typical fault of WXR, this paper studies the fault tree analysis (FTA) method of system safety analysis. Through implementing the qualitative and quantitative analysis, this paper calculates the minimal cut sets and the probability of top event so as to provide specific quantity for the best goal of system safety control. After calculating the importance of the basic events, this paper sorts the importance values from big to small in order to establish the priorities of basic events to performing safety control. In this way, the guidelines for improving the efficiency of system safety optimization are introduced.关键词
