Abstract: The flight verification is an important means to improve the technical and operational reliability of the aerospace components. In the context of the the key electronic components and their key technical parameters, the flight verification mainly concerns those mechanisms that would significantly affect the functions and the performance of the key components, the component application reliability and the operational strategy. This paper first analyzes the test requirement and the work flow of the flight verification, then explains the design principle of a flight verification device, with suggestions of the test data analysis combined with the work practice.
