Abstract:
1. A method of managing airspace through which a plurality of aircraft are flying, comprising: obtaining user preferred aircraft intent data that describe unambiguously user preferred trajectories to be flown by each aircraft through the airspace; obtaining a user preferred time of arrival for each aircraft; calculating the user preferred trajectories from the user preferred aircraft intent data; detecting one or more conflicts in the user preferred trajectories, and identifying the conflicted aircraft predicted to fly the detected conflicting trajectories; revising the user preferred aircraft intent data of at least one of the conflicted aircraft to produce revised aircraft intent data having a corresponding revised trajectory; for each revised trajectory, calculating a penalty function value, wherein the penalty cost function comprises a function of, for each of the plurality of aircraft, a corresponding revised flight duration, a corresponding fuel consumption, a corresponding user preferred value for flight duration, and a corresponding user preferred value for fuel consumption, and further revising the revised aircraft intent data of at least one aircraft to produce a corresponding trajectory such that the penalty function values are distributed among the conflicted aircraft subject to revised trajectories more equitably or more fairly; sending revised aircraft intent data to the corresponding conflicted aircraft; and ordering a change of at least one of speed and direction of the corresponding conflicted aircraft.
