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 global 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;
using the comparison of the user preferred trajectories to identify conflicted aircraft and to place the conflicted aircraft into conflict dependent networks such that each conflict dependent network contains a set of all aircraft in conflict with each other, either directly or indirectly, such that each conflicted aircraft can be a member of one conflict dependent network only;
for each conflict dependent network, calling an initial conflict resolution procedure comprising;
revising the user preferred aircraft intent data of one or more of the conflicted aircraft of the conflict dependent network to produce revised aircraft intent data defining a corresponding revised trajectory in a way that should remove conflicts from within that conflict dependent network; and
sending the revised aircraft intent data to the corresponding conflicted aircraft.

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.

20. A system for managing airspace through which a plurality of aircraft are flying, the system comprising:
-
a computer apparatus; a non-transitory computer readable medium comprising instructions stored thereon, that when executed by the computer apparatus, causes the computer apparatus to; receive, from the aircraft, user preferred aircraft intent data that unambiguously defines the user preferred trajectory of each aircraft; call an initial global 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; use the comparison of the user preferred trajectories to identify conflicted aircraft and to place the conflicted aircraft into conflict dependent networks such that each conflict dependent network contains a set of all aircraft in conflict with each other, either directly or indirectly, such that each conflicted aircraft can be a member of one conflict dependent network only; for each conflict dependent network, calling an initial conflict resolution procedure comprising; revising the user preferred aircraft intent data of one or more of the conflicted aircraft of the conflict dependent network to produce revised aircraft intent data defining a corresponding revised trajectory in a way that should remove conflicts from within that conflict dependent network; and send the revised aircraft intent data to the corresponding conflicted aircraft. - View Dependent Claims (21, 22, 23)

receive, from the aircraft, user preferred aircraft intent data that unambiguously defines the user preferred trajectory of each aircraft; call an initial global 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; use the comparison of the user preferred trajectories to identify conflicted aircraft and to place the conflicted aircraft into conflict dependent networks such that each conflict dependent network contains a set of all aircraft in conflict with each other, either directly or indirectly, such that each conflicted aircraft can be a member of one conflict dependent network only; for each conflict dependent network, calling an initial conflict resolution procedure comprising; revising the user preferred aircraft intent data of one or more of the conflicted aircraft of the conflict dependent network to produce revised aircraft intent data defining a corresponding revised trajectory in a way that should remove conflicts from within that conflict dependent network; and send the revised aircraft intent data to the corresponding conflicted aircraft.
