S-AF4.3 — CTOT to TTA for ATFCM

Target Times (TT) shall be applied to selected flights for ATFCM purposes to manage ATFCM at the point of congestion rather than only at departure. Where available, the Target Times of Arrival (TTA) shall be derived from the Airport Operations Plan (AOP). TTAs shall be used to support airport arrival sequencing processes in the en-route phase.

Deployment Target Date


System Requirements

- Network Manager's systems shall support target time sharing. Systems shall be able to adjust Calculated Take- off Times (CTOTs) based on refined and agreed TTAs at the destination airport; TTAs shall be integrated into the AOP for subsequent refinement of the NOP
- Flight data processing systems may need to be adapted in order to process downlinked trajectory data (ADS-C EPP)

Geographical Scope

Network Collaborative Management shall be deployed in the EATMN. In ATC centres in Member States where civil-military operations are not integrated (Austria, Belgium, Bulgaria, Czech Republic, France, Ireland, Italy, Portugal, Romania, Slovakia and Spain), Network Collaborative Management shall be deployed to the extent required by Regulation (EC) No 552/2004, point 4 of Part A of Annex II.
