Title: FLIGHT CONTROL METHOD AND SYSTEM AND UNMANNED AIRCRAFT
Abstract:
A flight control method, an unmanned aircraft and a flight control system thereof. The method comprises: acquiring current electric energy information about a battery of an unmanned aircraft (101); when the current electric energy information satisfies a first electric energy alarm condition, acquiring a current state of the unmanned aircraft (102); and according to the current state of the unmanned aircraft, controlling the unmanned aircraft in entering a corresponding safety protection mode (103). When it is detected that the unmanned aircraft is in a low electric energy situation, the unmanned aircraft is controlled in entering a safety protection mode corresponding to a current state thereof, thereby guaranteeing the flight safety of the unmanned aircraft, and reducing the crash probability of the unmanned aircraft.
