How will Arrival Management change in SESAR?
Arrival management in the future (a significant evolution from today’s AMAN) will consider traffic much earlier for the preparation of the sequence and required spacing to enable an optimal approach to be flown. The aim is to ensure an efficient descent portion of the RBT, undisturbed by tactical actions that might jeopardise the lateral or vertical efficiency of the arrival. In the future scenario the airport will be served by a set of optimised arrival routes. The arrival manager function will be able to allocate arrival routes and set constraints such as Controlled Time of Arrival (CTA) on merging points with the objective of building an optimum sequence. The CTA technique fits well with Time Based Spacing (TBS) which would follow on after passing the CTA point.
