The approach simulator guarantees good operational training and ensures that the air traffic controllers can maintain their qualifications and skills with regard to radar control, methods, procedures, etc., as well as training in new functions before they are introduced to the ATC systems for operational use.
The approach simulator uses the same HMIs (Human/Machine Interfaces) that are used in the operational systems. Recorded and/or simulated flight plan and radar data is used to give as realistic training as possible.
