Virtual reality(VR) technology is a comprehensive technology rising in the 20th century. With the development of science and technology, VR has been rapidly developed and widely used. Aiming at the problems existing in traditional civil aircraft training such as boring courses, low training efficiency and high cost, VR technology has been gradually applied to civil aircraft training, and has been greatly developed. This paper introduces the VR training system built by a civil aircraft training center, including three VR training systems: large-scale immersion VR, helmet VR and desktop VR, and details the software and hardware composition of the above three VR training systems, including display system, interactive equipment and development software; The advantages and disadvantages of the three VR training systems are briefly summarized. Aiming at the complex and tedious problems in the process of developing training content, this paper introduces the development process of non programming courseware based on Unity 3D, which is applicable to three VR training systems. Finally, the development direction of VR technology in civil aircraft training was prospected.
