AUO-0223 — Harmonised and improved integration of airspace and ATC constraints/procedures in trajectories calculated by FOCs and NM

This OI contributes to the progressive alignment of the AU and NM calculated 4D trajectories in planning phase. This alignment will be improved by clarifying and harmonizing airspace/route constraints publication and interpretation and agreeing on ATC constraints and procedures (in particular LOAs represented by PTRs in current Network operations) needed to be taken into account to generate the SBT/RBT. This OI addresses ATC constraints published either statically or activated dynamically with sufficient notice to be considered in AU flight planning. This OI is a key step toward the implementation of the SBT concept and will allow improving predictability both at AU and ATM sides as well as enabling fine-tuned trajectory management processes.
