The latest controller decision support tools help to ensure safe separation between aircraft during en-route flight phases as well as in the terminal manoeuvring area. As a consequence, 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, and reducing the need for so many tactical interventions. By enhancing the accuracy of conflict detection, SESAR aims to improve the provision of separation services in all phases of flight.

The enhanced ground-based tools being researched by SESAR include conflict detection and resolution featuring what-if or what-else scenarios; and flight conformance monitoring service, which can detect non-compliance with air traffic control instructions and issue alerts. Further data inputs include the use of aircraft enhanced flight plan data, improved weather information such as wind data, enhanced surveillance data based on Mode S transmissions and aircraft-derived data (ADS-C). Research into the use of these advanced support tools is being carried out in the free route airspace environments and in conjunction with extended air traffic control planning activities such as collaborative control, described in the previous solution #PJ.10-01c, and the multi sector planning position and extended ATC planning role described in solution #PJ.10-01a and #PJ.09-02.
