A control method for takeoff/landing of a vertical takeoff/landing aircraft, the control method comprising:
- causing an automatic takeoff/landing system of the vertical takeoff/landing aircraft, which executes takeoff/landing control for takeoff/landing of the vertical takeoff/landing aircraft at a landing target point provided on a moving object, to execute
- acquiring a direction of a relative wind in the moving object,
- acquiring a ship heading of the moving object,
- causing an aircraft heading of the vertical takeoff/landing aircraft to face the direction of the relative wind based on the acquired direction of the relative wind and the ship heading of the moving object, controlling the flight such that an aircraft heading of the vertical takeoff/landing aircraft becomes a direction by adding the ship heading of the moving object to the direction of the relative wind, in a state in which the aircraft heading of the vertical takeoff/landing aircraft faces the direction of the relative wind, and
- causing the vertical takeoff/landing aircraft to takeoff/land at the landing target point.
