Abstract: Provided is a vertical take-off/landing aircraft controlling a tilt angle of a main rotor, based on a vertical posture control signal during low-speed flight, wherein, when an aircraft steering signal including a vertical posture control signal for changing the pitch posture angle of the vertical take-off/landing aircraft by a first pitch posture angle is obtained, a flight controller determines a tilt angle of the main rotor with reference to the first pitch posture angle and generates a tilt angle control signal for the main rotor based on the determined tilt angle.

Abstract: A method and a system for landing an Unmanned Aerial Vehicle (UAV) are provided. The method for landing the UAV includes recognizing a mark installed to the UAV through a plurality of vision sensors installed around a landing point of the UAV, and calculating a relative location of the UAV based on the landing point using the mark recognized by the vision sensors. Hence, the plurality of the sensors installed near the landing point can calculate more precise location and position of the UAV using the relative location of the UAV and the absolute location of the landing point by recognizing the mark attached to the UAV, and thus the UAV can land on the landing point accurately.
