1. A hybrid aircraft that flies using a plurality of rotors, the hybrid aircraft comprising:
a generator;
a battery charged with power generated by the generator;
a plurality of electric motors configured to rotate the respective rotors by the power generated by the generator and power supplied from the battery; and
a controller configured to estimate, according to a flight state of the hybrid aircraft, a power fluctuation value that is a fluctuation value of power used by the plurality of electric motors, set a target remaining capacity of the battery based on the fluctuation value of power, and control charging and discharging of the battery in a manner that a remaining capacity of the battery approaches the target remaining capacity.
