The invention provides an aircraft ground maintenance virtual training device comprising three displayers, an operating terminal and a server. The three displayers are respectively a dynamic schematic diagram displayer, a three-dimensional virtual cabin displayer and a three-dimensional outer scene auxiliary training displayer, and the three displayers and the operating terminal are bidirectionally connected with the server and the three displayers are connected with the operating terminal. Besides, the operating terminal is internally provided with a virtual training program used for aircraft ground maintenance virtual training. The virtual training program is externally connected with a given preset fault program so as to cultivate students to master the capacity of handling similar problems in the actual maintenance process. Furthermore, real support equipment can be directly used after learning through virtual common ground support equipment so as to enhance the working efficiency. Life loss and fuel consumption of the aircraft engine and main equipment caused by real equipment training can be greatly reduced by using the desktop type virtual training equipment so as to save large amount of maintenance training expenditure.
