As a helicopter. The blades on the V-22 Osprey are much too long for it to land as a conventional airplane would.
They tilt the front of rotor down
The 'Osprey' has a pair of tilt-rotor propellers. Configured with one propeller on each wing, the rotors can then 'tilt' from the vertical position to the horizontal position, allowing the craft to hover or land an take-off vertically, like a helicopter. Answer: The fact that it's the only (first) tilt-rotor aircraft to enter service. The concept itself was tried and tested on numerous previous aircraft dating back to at least 1942.
A small tilt is applied to one rotor to counteract yaw from unbalanced rotor torque

The rotor blades tilt as they rotate, giving lift. The entire hub can be tilted for direction of flight.

Perhaps you are thinking of the Osprey or some other "tilt-rotor" aircraft. There is also the auto-gyro which works by propelling itself forward with a regular propeller & flies by using the lift of a windmilling main rotor.

to detect a slight rise or fall in the elevation and tilt of the land.
Vertical takeoff and landing (VTOL), usually the domain of helicopters, can also be achieved by the Harrier Jump Jet, and the Osprey tilt-rotor aircraft.
