Test and calibration is the basis for achieving accurate and consistent measurements of performance parameters of airborne equipment, ensuring product quality and improving the efficiency of equipment support. Scientific and reasonable requirement analysis is the prerequisite for efficient test and calibration. Due to the lack of standards and guidebooks, there are many problems in the practice, such as incomplete requirement, unclear parameter definition and unreasonable index requirements, etc. This paper discusses the connotation and present situation of test and calibration requirement analysis, puts forward a reasonable method, work flow and some suggestions, which can be directly applied to engineering practice.
