Why do pilots complete so many hours of training in a simulator? Simulators are an extremely effective means of training employees and preparing them for challenging situations. Everyone is probably familiar with the classic driving simulator. However, this concept can be applied to a wide variety of devices, vehicles or machines in order to train the handling of these, even in challenging situations. It is possible to simulate complex scenarios, even with several participants. Simulators can be created completely virtually (virtual reality) or only with virtual parts - with the help of augmented reality. In particular, the combination of real elements, such as a physical vehicle, and a digital simulation of the situation fascinates users and leads to particularly good acceptance. Another major advantage of simulations in general is that they can be repeated as often as required without using up resources.
