The traditional test verification work of civil aircraft is facing many challenges; the virtual test technology has become the key technology of aircraft system testing and evaluation work,which is an effective supplement to the traditional physical testandverification. But the current development of the virtual test technology of civil aircraft design field in our country is not very mature, this paper discussedtheapplication goalof virtual test technology in aircraft development, from the dimension of system integration and the dimension of function application, the whole framework of virtual experiment is conceived, the key technologies to solve the current problems in virtual test are put forward, summarized the development path of civil aircraft virtual test system.
