A controller in an unmanned aerial vehicle determines whether the unmanned aerial vehicle is beyond a visual range within which the unmanned aerial vehicle is visible to an operator. When the unmanned aerial vehicle is determined to be beyond the visual range, the controller determines whether the operator is controlling the unmanned aerial vehicle using the control device while viewing video on a head-mounted display. When the operator is determined to be controlling the unmanned aerial vehicle using the control device while viewing video on the head-mounted display, the controller controls flight of the unmanned aerial vehicle in accordance with control information for controlling the unmanned aerial vehicle. When the operator is determined not to be controlling the unmanned aerial vehicle using the control device while viewing video on the head-mounted display, the controller does not control flight of the unmanned aerial vehicle in accordance with the control information.
