Current air traffic management is based on a filed flight plan and tactical interventions by ATC as the flight progresses. The idea behind trajectory-based operations (TBO) is to enable the ATM system to know and, where
appropriate, modify the flight’s planned and actual trajectory, before or during flight, based on accurate information that has been shared by all stakeholders. This will lead to efficiency gains for both individual aircraft and for the network as a whole.

TBO calls for full integration of flight information in order to create a synchronised view of flight data by all actors involved. This shared information also includes any constraints imposed by the various ATM stakeholders.
SESAR is addressing the operational and technical procedures needed to manage this shared information, and the scenarios where a stakeholder is allowed to update a trajectory, including any potential collaborative decision making, ahead of any change in the reference business trajectory (RBT). The research covers air/ground exchanges for RBT management, task management by planning controllers, as well as cockpit display tools. Sharing a single flight data set amongst all actors will improve the performance of the network as a whole and
enable user-specific needs to be accommodated.
