This Solution was formerly part of PJ.10-02a2-W1

Controllers rely on a high number of tactical interventions and use multiple radar vectors, stepped climbs and descents in order to maintain separation between aircraft in high traffic situations. SESAR is looking at ways of delivering more accurate predictions of present and future aircraft positions through the use of aircraft-derived data in order to reduce the need for so many tactical interventions. By enhancing the accuracy of conflict detection, SESAR aims to improve the provision of separation services during en-route phases of flight and in the terminal manoeuvring area.

This candidate solution aims to provide the planning controller or tactical controller with conflict detection and resolution tools based on enhanced ground predicted trajectory obtained using improved aircraft data. This can include aircraft trajectory information downlinked via ADS-C, aircraft extended projected profile (EPP), electronic flight plan data (eFPL) and recent meteorological data. Additional trajectory information may also be made available using air/ground data link exchanges using real recorded downlinked ADS-C data.

Research into the use of these advanced support tools is being carried out in the free route airspace environment in conjunction with extended air traffic control planning activities such as collaborative control described in solution PJ.10-W2-73 CC, and the multi-sector planning position and extended ATC planning role developed in wave 1.
