SYSTEM AND METHOD FOR DETERMINING AN ALTERNATIVE FLIGHT ROUTE BASED ON SECTOR GEOMETRY

A flight routing system (10) for determining an alternative route for an aircraft (20) based on an airspace (42) partitioned into a plurality of sectors (40), and an original flight route (30) having an initial point of takeoff (32) and a destination point is disclosed (54). The flight routing system (10) includes a processor (320) and a memory (330) storing instructions executable by the processor to perform operations including determining a plurality of points within each of the plurality of sectors. The plurality of points are each located along an edge (62) of one of the plurality of sectors (40). The processor (320) also performs operations including determining at least one connecting arc for each sector, where the connecting arc connects a first point with another point within each sector. The processor (320) further performs operations for determining a complete time-based airspace (150) network based on at least a forecast capacity.
