Expected Impact

AUDIO demonstrates the extension of support systems originally designed for controllers. Available local airport data will be shared and connected to onboard systems. In the case of a successful demonstration, the new functionalities are ready to be implemented in new EFB applications used in Lufthansa aircraft or other airlines, thus providing significant benefits at airports providing local data.


The demonstration is expected to show the benefit of providing local airport data to the flight crew. By providing the planned taxi route and time calculated by the A-SMGCS routing function to the cockpit, benefits are expected in terms of safety and predictability, as well as an increase in situational awareness. The safety and predictability gain is clearly relevant for passengers. For the public at large, environmental benefits are also expected. The optimised surface routing means optimised aircraft movements on the ground, with reduced fuel burn (fewer carbon emissions, less noise and less cost).


As Airspace Users will be aware of the route planning, the departure sequencing should be more stable. In providing the planned information to the cockpit, flight crews are aware of the planned trajectory and can adjust operations, which will lead to a stable sequence and more reliable meeting the TTOT.  Equipped with this additional information, on-board operations are expected to run smoother as crews are aware of the planned ground trajectory and the surrounding complex environment. This also allows them to react more easily to last-minute re-planning of routes. The results: safer ground movements, more reliable targeted take-off time and sequences, less complexity for the crew, more efficient taxiing, and fewer emissions due to lower fuel consumption.


Exchanging ground traffic information results in common situational awareness between all stakeholders. The overall safety guaranteed by Air Traffic Controllers is enhanced by pilots’ better awareness. Consequently, the number of conflicting situations during airport surface operations is expected to be reduced. Visualization of the taxi route will improve operations (reduced route deviations, enhanced predictability, reduction of potential conflicts) for Airport Operators.
