Abstract: The present disclosure provides a method for controlling a return flight of an unmanned aerial vehicle (UVA). The method includes controlling the UAV to fly to a predetermined cruising altitude, and controlling the UAV to return horizontally at the predetermined cruising altitude based on a first predetermined horizontal speed control value when determining that a remaining power of the UVA is less than or equal to a predetermined return flight power threshold; and controlling the UAV to perform a forced landing and the return flight based on the first predetermined horizontal speed control value and a predetermined descent speed control value when determining that the remaining power of the UAV is less than or equal to a predetermined descent power threshold in the process of the horizontal return at the predetermined cruising altitude.
