A rotary-wing aircraft is a broad category of any aircraft with a moving wing, including helicopters and autogyros. This is to distinguish from fixed-wing aircraft. A third type, tilt-wing (or tilt-rotor) aircraft, are a mix of the two, as the lift surfaces in vertical flight are rotary, but stationary in forward flight.

An autogyro is an aircraft supported in flight by a rotor driven solely by aerodynamic forces. ... An Air France Boeing 777, a modern passenger jet. ... The Bell-Boeing V-22, an example of a tiltrotor aircraft A tiltrotor aircraft combines the vertical lift capability of a helicopter with the speed of a turboprop aeroplane. ...

This downward deflection causes an opposite lifting force on the wing (described by Newton's third law) and a lower pressure on the upper surface, higher pressure on the lower surface.
In the cross system, the rotarywingaircraft resembles a traditional fixed-wing airplane, with the two main rotors mounted at the extremities of its wings.
Such helicopters are rare, because structural integrity of the wings is difficult to maintain against the amplified resonance of far off-board rotor-turbine units.
A conventional aircraft is able to fly because the forward motion of its angled wings forces air downwards, creating an opposite reaction called lift that forces the wings upwards.
A small, fixed wingaircraft can be stable enough that a pilot can let go of the controls while looking at a map or dealing with a radio, and the plane will generally stay on course.
Tension is maintained on the cable as the helicopter descends which assists the pilot with accurate positioning of the aircraft on the deck; once on deck locking beams close on the probe, locking the aircraft to the flight deck.
