ATC24 — Network Manager Trajectory Information Enhancement

The NM Trajectory information could be enhanced by using Extended Projected Profile (EPP) data. Pending further validations, NM system could be capable of receiving and processing EPP data. For increasing the accuracy of NM systems trajectory prediction, some EPP elements might be used for the tactical trajectory update in the flight post departure phase. The displaying of EPP and the EPP warning are not needed for NM, as they are pure ATC functions.

Although there is no confirmed planning for NM EPP validation activities, it should be noted that NM’s EPP implementation is not linked with the EPP display and warnings by ANSPs and therefore it will not impact their plans.

System requirements:

Network Manager should, subject to successful industrialisation target date, use some elements of the downlinked trajectories to enhance the calculation/predictions of NM systems trajectories.

NOTE FOR MILITARY AUTHORITIES: It is the responsibility of each military authority to review this Objective IN ITS ENTIRETY and address each of the SLoAs that the military authority considers RELEVANT for itself. This has to be done on top and above of the review of "MIL" SLoAs which identify actions EXCLUSIVE to military authorities.
