DCB-0215 — Consolidation of imbalances and arbitration of Trajectory Management solutions

Measures from Airports (including Multi-APOC), ACCs, AUs and NM will be integrated and coordinated within SBT and RBT mechanisms to ensure the stability and performance of the network. The integration of these 4D constraints issued from multiple sources will be managed through new rules and mechanisms (including AU priority and preference, 4D Targets and Tolerance Windows, arbitration of TM solutions) that will replace current slot allocation (based on first planned/first served principle). SBT planning and trajectory management will rely on dynamically updated 4D constraints providing a common baseline for AU and ATM Network operations to reach agreement on the SBT and the required SBT tolerances
