This candidate solution aims to increase the quality of separation management through the introduction of automation mechanisms while taking into account controller tasks and aircraft characteristics. SESAR is looking to reduce controller workload, reduce separation buffers, and facilitate new controller team organisation in the en-route and terminal manoeuvring areas of flight.
Controllers are assisted in their separation tasks by technical functionalities, which use advanced data to increase the quality of services provided. For example, ground trajectory prediction is improved when the ground system knows the complete flight profile through the full integration of ground trajectory constraints with the air trajectory. This includes predicted climb and descend speeds downlinked from the aircraft using automatic dependent surveillance – contract (ADS-C) and extended projected profile, as well as the integration of input data derived from meteorological services.
Potential conflicts are minimised through controllers’ obligation to confirm each recommended intervention, and to uplink ‘closed-loop’ trajectories to the aircraft, which provide a trajectory-based clearance and reduces uncertainty in a dynamic airspace management environment. Conflict resolution also takes account of the navigation capability of the aircraft.
The candidate solution considers the impact of mixed-equipment fleet, comprising non-equipped and equipped aircraft, and enhanced conformance monitoring where the shared aircraft trajectory is checked against the calculated ground system trajectory.
