The advantage of such a 3D virtual aircraft is that it is usable both for theoretical and for practical training. In principle, NLR is able to model all complex mechanical systems in the aircraft, including systems that normally cannot be demonstrated in an aircraft on the ground, such as the landing gear. It is also possible to simulate normal and abnormal aircraft behaviour. What’s more, a virtual aircraft is available any place, any time, and nothing can wear out. The intention is for students to be able in future to exercise in making repairs by means of the 3D model without anything getting broken. And because a physical aircraft is no longer necessary, normal flight operations can continue as usual. Consideration is further being given to using HoloLens as performance support in carrying out tasks on a real aircraft during a mechanic’s normal work. Instructions about the actions required will be projected visually on to the aircraft.
