Airspace users share their flight plans with stakeholders on the ground so flights can be managed as closely as possible to their ideal profile. This shared business trajectory (SBT) is progressively refined prior to departure to create a RBT agreed by air traffic control and the airspace user. This becomes the flight plan that is then filed. SESAR 1 introduced an extended flight plan (eFPL) to expand the information available for this collaborative decision making process in order to improve trajectory prediction. The enriched data set is reflected in ICAO’s longterm vision of flight and fFlow information for a collaborative environment (FF-ICE).

Latest SESAR research aims to enhance further EFPL data to improve alignment of trajectories between air traffic control and airspace users. Included in this broader information exchange is the filed trajectory and agreed trajectory – with airport standard arrival and departure routes – as well as flight specific performance data, which allows air traffic control to recalculate, when needed, a trajectory closer to the preferred trajectory as would be generated by the airspace user. The activity supports trajectory-based operations by helping to align and unify air traffic control and airspace users’ trajectories in the pre-flight phase, and improves target time management for the network as a whole. The solution is part of synchronised deployment, in accordance with the PCP.
