Cooperative traffic management

Working together to make the best use of the air traffic management resources and reducing the need for air traffic flow and capacity management regulations.

This project provides solutions for optimising the network planning, making the best use of the ATM resources and reducing the need for ATFCM regulations, through collaborative processes involving all actors and continuous information sharing of individual and local preferences, in both the planning and execution phases of ATM.

Upgrades

The following improvements to our current systems will be implemented as part of this project: 

  • short term ATFCM measures (STAM) - these system upgrades for network optimisation allow the application of targeted ATFCM measures (coordinated throughout European airspace) on the day of operations. STAM includes advanced scenario management, network impact assessment and what-if capabilities for all network actors, system based coordination, supported by wide information sharing via SWIM and automation;
  • flight plan predictability - the system upgrades support the identification of yo-yo flights, exchange of trajectory information with ATC (within and beyond Europe) and with airspace users via system-wide information management (SWIM), support to what-if reroute for ATC, integration of ADS-B data;
  • target time operations - support to Target Times for en-route and airport arrival. Integration of airports constraints and en-route constraints;
  • extended arrival management - support to ATC sequencing processes, either directly by improving predictability and smoothing the arrival sequence, or more indirectly to en-route ATC in the case of extended arrival management (AMAN) procedures. Integration between local and network demand and capacity balancing (DCB) processes through SWIM;
  • user driven prioritisation process - support airspace users to optimise departure sequences for flights affected by network constraints, by allowing swap of ATFCM slots, and by allowing Airspace Users to prioritise flights.

Benefits

A wide deployment of STAM is expected to further minimise the need for regulations. System supported ATFCM coordination processes will ensure adequate involvement of all operational partners in establishing measures. Improved predictability, required to effectively   execute ATFCM measures, will increase ATC confidence in ATFCM planning allowing a reduction of capacity margins.
