Abstract�� The aviation equipment availability analysis method was reviewed and the influential factors of aviation equipment availability were classified as three categories.The newly increased influential factors of aviation equipment availability were analyzed through analyzing in the influence of prognostics and health management (PHM) technology to the availability. These factors were specified in term of the sources as two categories: the operate factors and the design factors. Four reasonable assumptions to simplify the simulation process. were provided. Furthermore, the design factors were divided into five categories. Combined with an example, the definitions of the simulation inputs of aviation equipment availability were given with the values of them. And the output of the simulation process is the steady-state availability under given conditions. Simultaneously, the analytical algorithm of it is pressed. Then the compositions simulation program and its flow chart were detailed described. The simulation results of the example were given by graph. At the same time the processes and conclusions of univariate analysis and multi-coupling analysis were given to verify the feasibility of the analysis mentioned.
