1. A computer-implemented method of managing airspace through which a plurality of aircraft are flying, comprising:
- receiving, from the aircraft, user preferred aircraft intent data that unambiguously defines the user preferred trajectory of each aircraft;
calling an initial conflict detection procedure comprising;
calculating the corresponding user preferred trajectories from the user preferred aircraft intent data; and
comparing the user preferred trajectories so as to identify one or more conflicts between trajectories and to identify conflicted aircraft predicted to fly the identified conflicting trajectories;
calling an initial conflict resolution procedure comprising;
selecting one or more identified conflicts, characterising the selected conflict and responsively revising the user preferred aircraft intent data of one of the aircraft involved in the selected conflict in a way that should remove the conflict;
after calling the initial conflict resolution procedure, calling a further conflict detection procedure comprising;
calculating revised trajectories from the corresponding revised aircraft intent data;
comparing the user-preferred trajectories for aircraft not subject to revised aircraft intent data and revised trajectories for the aircraft subject to revised aircraft intent data so as to identify one or more conflicts between trajectories and to identify still-conflicted aircraft predicted to fly the identified conflicting trajectories; and
if conflicts are identified during the further conflict detection procedure, calling a further conflict resolution procedure,wherein the further conflict resolution procedure comprises selecting one or more identified conflicts, characterising the selected conflict and responsively revising the user preferred aircraft intent data or revised aircraft intent data of one of the aircraft involved in the selected conflict in a way that should remove the conflict, and calling the further conflict detection procedure;
orif no conflicts are identified during the further conflict detection procedure, continuing to the step of sending the revised aircraft intent;
sending the revised aircraft intent data to the corresponding conflicted aircraft; and
managing the airspace by ordering at least one of the aircraft to alter course.

Abstract
A method of detecting conflicts between aircraft passing through managed airspace, and resolving the detected conflicts strategically. The method may include obtaining intended trajectories of aircraft through the airspace, detecting conflicts in the intended trajectories, forming a set of the conflicted aircraft, calculating one or more revised trajectories for the conflicted aircraft such that the conflicts are resolved, and advising the conflicted aircraft subject to revised trajectories of the revised trajectories.
