Control apparatus, aircraft control method, and non-transitory computer-readable medium

A control apparatus includes a decision unit, a destination point determination unit, and an aircraft control unit. The decision unit decides, when an aircraft flies by using a battery unit as a power source, whether a remaining quantity of the battery unit is equal to or less than a reference value. The destination point determination unit estimates, when it is decided that the remaining quantity of the battery unit is equal to or less than the reference value, a location where a light quantity is equal to or more than a reference by using information from various types of sensors mounted on the aircraft. Then, the destination point determination unit determines, as a destination point of the aircraft, the estimated location. The aircraft control unit controls a mechanism of the aircraft so as to move the aircraft to the destination point determined by the destination point determination unit.
