Abstract: A method for supporting aerial operation over a surface includes obtaining a representation of the surface that comprises a plurality of flight sections, and identifying a flight path based on the representation of the surface. The flight path allows an aircraft, when following the flight path, to conduct an operation over the flight sections.

Abstract: A method for supporting aerial operation includes obtaining a real-time location of an aircraft, obtaining a location of a supply station, obtaining a location of a next waypoint, and controlling the aircraft based on a status parameter related to a flight status of the aircraft associated with the real-time location of the aircraft. Controlling the aircraft includes controlling, in response to the status parameter satisfying a first preset condition, the aircraft to fly to the next waypoint; and controlling, in response to the status parameter satisfying a second preset condition, the aircraft to fly to the supply station.
