An aircraft includes a rotary wing comprising a main rotor and a tail rotor, a drive unit configured to rotate the rotary wing, an information acquirer for acquiring position information of an obstacle relative to the aircraft, a display, and a controller including at least one processor and at least one memory coupled to the processor. The processor executes processing including deriving a direction, a horizontal distance, and a vertical distance of the obstacle with respect to the aircraft, based on the position information of the obstacle, determining, for one or both of the main rotor and the tail rotor, whether the direction, the horizontal distance, and the vertical distance satisfy a first distance condition, and displaying an index corresponding to the vertical distance at a display position on the display when the first distance condition is satisfied, the display position being identified by the direction and the horizontal distance.

Aircraft

A rotary-wing aircraft includes a fuselage, and an external device. The fuselage is provided with a rotary wing. The external device is mounted on the outside of the fuselage. The external device includes a mounting device, a mass variation device, and a damper. The mounting device is fixed to the fuselage and disposed so as to project in a lateral direction of the fuselage. The mass variation device is mounted on the mounting device and has mass that varies as the mass variation device is used. The damper couples the fuselage to the mounting device and supports the mounting device. The damper includes a stiffness variable mechanism configured to change stiffness of the damper in response to variation in the mass of the mass variation device.
