Abstract: Aircraft maintenance is an important part of the aviation safety, which requires maintenance engineers have a higher quality of professional level. Colleges and universities are to the tasks of the output of high quality maintenance engineers. In the paper, for the problem that the students of aircraft electrical maintenance major lack of engineering application ability, apply enlightenment of the five law gestalt to the actual practice teaching. Practice results show that most students estimate very well and effectively mobilize the learning enthusiasm and passion. By the processes, students can effectively combine learning theoretical knowledge and practice, enrich the professional knowledge, and even improve the ability of practical engineering application.
