Flow and Capacity Management today The European Air Traffic structure is a large, intricate network Different actors, with different and potentially conflicting interests The Flow Management system must be taken to a new level Any clear capacity breakthrough??

Pave the way for the future Introduce flexibility in the Flow Management system Do it in a collaborative Manner Involve all the relevant partners

Flexibility Airlines know better what’s good for them Local entities can take more immediate actions Implementation of new tools or operational procedures should be prototyped in small scale but real operational environment

Flights have different values to airlines Airborne Sequence Airborne Flow Management Airline-optimal Sequence

En route to en-route A sequence “contract” is defined to de-complexify C1 RTA C2 RTA C3 RTA A sequence “contract” is defined to de-complexify traffic flows Converging flows create high workload and complexity B1 RTA B2 RTA B3 RTA A1 RTA A2 RTA A3 RTA

En route to airport The station keeping contracts are passed on to upstream centres The controllers can delegate separation monitoring (station keeping) An optimal arrival sequence is calculated (*) (*) With potential input from AOS

Conclusion CDM is a part of a more global concept: . Collaborative ATM Co-operation is needed not only between different actors, but also within the same category: this is the Single Sky spirit The implementation approach should be users-oriented, validated via small-scale experiments. It is the sine qua non condition to safer and more efficient skies
