Airport landing method for vertical take-off and landing fixed-wing unmanned aerial vehicle

The invention relates to the technical field of unmanned aerial vehicle landing, and discloses a vertical take-off and landing fixed-wing unmanned aerial vehicle airport landing method, which comprises the following steps that S1, an unmanned aerial vehicle determines a landing airport according to the remaining endurance mileage and the airport distance; s2, when the unmanned aerial vehicle arrives above the landing airport, landing guidance is carried out on the unmanned aerial vehicle; s3, performing height acquisition on the unmanned aerial vehicle through a data acquisition module of the unmanned aerial vehicle and a guiding module of a landing airport, and correcting a flight path of the unmanned aerial vehicle at any time according to a landing identifier on the ground; s4, when the height of the unmanned aerial vehicle descends to a certain height, opening the vertical take-off and landing fixed wings, and then closing the propulsion motors, so that the purpose of slow descending is achieved; and S5,
