Furthermore, the large size of the desktop enables the instructor to access information about the simulation while preparing a drive or evaluating lessons. Each screen covers several functions: the left-hand screen allows the instructor to follow the actions of the trainee, to provoke events, to change perspectives, to log  sequences, and to watch replays, while the right-hand screen covers administrative tasks. It shows data and results of the trainee's progress, and can be used to prepare new scenario sequences for future lessons. A copy of the main-screen scenario can be proceeded to a projector to be used in a classroom.
