From the flight evolution data it collects, the Enhanced Tactical Flow Management System (ETFMS) knows which flights are airborne. This makes it possible to identify flights which were planned to take off and those that are currently still on the ground.
The Flight activation monitoring (FAM) function enables us to:
- shift flights in time that are not reported as airborne after their expected take-off time;
- possibly suspend those flights which are still not reported as airborne after a certain time parameter;
- inform the aircraft operator and the departure tower of this development, prompting their reaction.
This improves network predictability.
