| Summary: | Human operating error is one of the important factors affecting the reliable operation of unmanned aerial vehicle (UAV) components, however, people always neglect human-operating-error of the existing unmanned aircraft systems and components reliability assessment methods. This article set the problem to the most important position to search, divided the scene of UAV components assignment to the Status debugging monitoring model and Preventive maintenance type. First, analysis of two scenarios UAV components made qualitative analysis of human error using the method of failure mode and effect analysis; and then put forward the two scenarios of human reliability assessment model, used to quantify the probability of human error. In example analysis, it considers the primary factors those affect humans reliability, to calculate and compare the proportion of human error at different situation. Results show that the proposed method can quantify human error probability, and quantitative characterization of human error can affect the reliability of the UAV components.
