Application of Weibull Analysis in the Optimization of Civil Aviation Aircraft Engineering Reliability Management

Reliability management is one of the basic work to protect the safety of civil aviation. At present, more and more domestic passenger planes are invested, but due to the low availability of data and limited number of aircraft, there are few studies on reliability management of domestic civil aviation aircraft. In this paper, the three-parameter Weibull distribution is used to analyze the small sample problem, and Take reliability management of pitot tube of domestic ARJ21 fleet as the research object, and the application of Weibull in the reliability management optimization of civil aviation aircraft engineering is explored.
