Method and device for controlling auto-stop of aircraft, and aircraft

Provided are a method and device for controlling the auto-stop of an aircraft, and an aircraft. The method comprises: detecting an operating state of an aircraft (S101); and if the detection result is that the aircraft is in a landing state, triggering the shutting down of the power output of the aircraft, so that the aircraft completes auto-stop after landing (S102). By means of the method or device, whether an aircraft has already landed can be accurately detected, and the power output of the aircraft is automatically shut down after the landing is detected, thereby saving the energy of the aircraft, and satisfying the automation and intellectualization requirements of users for the power shut-down control of the aircraft.
