The solution optimises the Target Time of Arrival (TTA) management at an airport to better integrate the out-of-area inbound flights.

TTAs for long-haul flights departing from airports outside of the European Regulation Area are computed by the FMP at the arrival TMA relatively to the Estimated Times of Arrival provided by the FOC before departure, for the aircraft to adjust their take-off time. Once the aircraft is airborne, the FMP at the arrival TMA receives a new TTA though the FOC. If needed, a revised TTA is sent though the FOC to the aircraft for the aircraft to adjust their speed in flight.

NM is in the loop all along this process, thereby ensuring that the network always has the most up-to-date information from long-haul flights:

  • Estimated Time Over (ETOs) received from long hauls outside IFPS zone are sent via B2B uplink channel to the NM to update ETFMS flight profiles;
  • Target Time Over (TTOs) are sent via B2B uplink channel to update ETFMS flight profiles and for NM to have full awareness of the airport targeted landing sequence;
  • Archive flight data from NM is retrieved via B2B downlink to establish a post-analysis treatment and presentation for statistics and analysis purposes.

Note: Out-of-area flights refer to flights departing from airports outside the European Regulation Area and arriving at European Regulation Area airports. The solution enables sequencing of the aircraft before their entry into lower airspace in order to optimize flight profiles, reducing vectoring, holding and fuel consumption, in particular in those periods where there are night curfew regulations in place and a demand-and-capacity imbalance at the time the airport opens caused by unregulated flights having departed from outside the European Regulation Area can result in long holding times. The solution takes also in consideration airspace user’s preferences (whenever it is possible) and Airspace Users having more than one flight in the sequence are able to swap their flights and exchange TTAs for specific flights. The solution is supported by a dedicated arrival management tool that computes the local TTAs and transfers them to the Airlines.
