Under the background of educational informatization reform, combined with the needs of "new engineering" construction, AABI (Aviation Accreditation Board International) certification and the development of civil aviation industry, an experimental teaching system based on virtual simulation technology is constructed, experimental projects are designed for practical engineering problems, and the whole process maintenance of aircraft fuel system is the main design line.By establishing the support matrix of talent training target points, the experimental needs and optimizing the experimental design are analyzed, the teaching implementation effect is good.
