Abstract
A computationally efficient method for automatically generating lateral resolutions for air traffic control problems for a given aircraft allows for prediction and evaluation of required separation between aircraft, between aircraft and airspace, and problems with assigned metering time. Upon a possible problem being predicted, lateral resolutions are created which provide plans to re-route the original flight trajectory of the aircraft in order to avoid a possible problem by examining the space surrounding the aircraft, iteratively adding data on each conflict encountered into a conflict database, calculating and probing maneuver trajectories for all conflicts in the conflict database, and selecting the most appropriate of the created maneuver trajectories.
Claims15
A method for generating problem resolutions for free flight operations in air traffic control, comprising the steps of:
- selecting a subject aircraft to be maneuvered;
- iteratively examining continuous space enveloping said subject aircraft for potential aircraft problems for a predetermined look-ahead time interval defining a plurality of examination passes;
- in each iterative examination pass, generating resolutions in response to all problems encountered in said examined continuous space, each resolution proposing a predefined type of maneuver for said subject aircraft;
- calculating parameters of requested maneuvers based on relative motion geometry, and
- probing each said generated resolution by examining said continuous space enveloping said subject aircraft affected by each requested maneuver applied thereto.
