TDI has been operational for more than 4 years in 8 airports in Switzerland and Germany.

The ATCO can select the RAP (Radar Approach Position) option at any moment. This immediately changes the system from a "Tower traffic management" tool  to an "Approach traffic management" tool together with its associated display settings.

This radar mode switching capability works as if an aircraft was visually tracked along its approach flight path thanks to an auto zoom-in or zoom-out process.

While in the RAP mode, the Controller handles the flight approaches and can also be aided by more precise measurement tools such as the grid display. The integrated flight plan information is also accessible in this configuration.

The same hardware equipment can thus be used for the 2 different applications which optimizes costs and space requirements, often critical in Towers.

The secondary radar window permanently shows the ATCO a complete overview of the current sky situation in order to provide a comfortable work environment.

Furthermore, being able to drag the windows from a screen to another considerably improves the global visibility and the HMI friendliness, something that ATCO's often attest to.

An additional benefit is that the same tool can handle the ACC Approach during daytime (heavy traffic) and the final Landing / Take-off function during nighttime (light traffic) in its RAP configuration.
 
Thanks to TDI's versatility the operational costs for personnel can easily be optimized.
