Trajectory-based operations (TBO) is a cornerstone of the SESAR vision paving the way for more predictable air traffic management. TBO is about sharing a common plan for a flight’s trajectory; matching that trajectory to the performance needs of the circumstances; and delivering the trajectory via ATC clearances. The project aims to deliver several solutions to enable trajectory-based operations during the planning and execution phases, taking a network view. Specifically, solutions will address flight and flow in a collaborative environment, making use of downlinked data from the aircraft (EPP) and improving both ATC and network processes through synchronisation of network and local trajectories.
