Widespread adoption of continuous descent approaches, rather than conventional stepped approach paths, is helping to reduce fuel consumption and noise during arrival and departure phases of flight. Efficiency can be further improved by support tools on the ground, which help to manage continuous trajectories, especially in dense and complex terminal environments. SESAR tools are designed to access relevant information such as speed advisories, which are calculated by the arrival sequencing manager, as well as a coordination tool, which facilitates the exchange of data between ATC sectors or ATC centres to share information about flight paths. The candidate solution also explores ways to improve the aircraft’s knowledge on its downstream profile while it is vectored.

Further development includes improving the situational awareness of the controller when both continuous descent and continuous climb operations are taking place. A decision support tool can assist with conflict detection, while a departure manager (DMAN) can help to manage events such as start-up, taxiing, and take-off time. This contributes to more accurate trajectory prediction and timing, and allows the controller to provide a conflict-free rate of climb or rate of descent rather than stepped flight paths.

The candidate solution is supported by standard arrival and departure routes, which comply with performance-based navigation principles. It addresses the dynamic use of lateral routes, but does not concern the management of the transition in and out of the terminal manoeuvring area, or with free route airspace.
