1. A method to wirelessly charge an urban air mobility, the method comprising:
acquiring, by a vehicle control unit, location information of a supply device supplying wireless power;
moving, by the vehicle control unit, the urban air mobility to the supply device based on the location information;
sensing, by the vehicle control unit, a sensor signal of the supply device based on a distance between the urban air mobility and the supply device becoming equal to or smaller than a first distance;
performing, by the vehicle control unit, first charging in which the urban air mobility moves to the supply device based on the sensed sensor signal, stops and performs wireless charging with first power;
performing, by the vehicle control unit, fine alignment based on a wireless charging efficiency calculated during the first charging;
performing, by the vehicle control unit, second charging in which wireless charging with second power is performed based on completion of the fine alignment;
analyzing, by the vehicle control unit, a beam pattern based on the first power received from the supply device during the first charging; and
wherein the fine alignment is performed based on the analyzed beam pattern.
