The PJ18-W2 4D Skyway project aims to continue the research on Trajectory Management (TM) to enable the deployment of the SESAR Trajecotry Based Operations (TBO).

• Solution PJ.18-W2-53 Improved Ground Trajectory Predictions enabling future automation tools.

The solution focuses on the operational validation of improved CD&R tools. The main goal is to increase the quality of separation management services reducing controller workload and separation buffers and facilitating new controller team organisations. The foundation is the improvement of the ground TP(EPP data beyond weight and CAS, known MET data or new MET data and capabilities, etc.).

• Solution PJ.18-W2-56 Improved vertical profiles through enhanced vertical clearances.

The objective of this solution is to develop an automation support for ATCOs to issue vertical constraints that support more efficient flight profiles while ensuring separation provision. First step, for flight still in climb, enhanced prediction of vertical profile data are presented to ATCOs to facilitate decision making. In a second more advanced step, the ATC system would generate proposals for conflict-free clearances that take anticipated aircraft performance into account, which can be uplinked to the flight crew by ATCO.
