VTOL

VTOL stands for Vertical Take-Off and Landing, referring to an aircraft's ability to take off and land vertically without needing a runway, much like a helicopter but often with fixed wings for forward flight.

TECHNICAL DEFINITION

VTOL (Vertical Take-Off and Landing) describes an aircraft's operational capability to execute vertical launch and recovery maneuvers, obviating the need for conventional runways and employing specialized propulsion systems like tiltrotors or vectored thrust for military applications in reconnaissance, transport, and close air support.

BACKGROUND

A vertical and/or short take-off and landing (V/STOL) aircraft is an airplane able to take off or land vertically or on short runways. Vertical takeoff and landing (VTOL) aircraft are a subset of V/STOL craft that do not require runways at all. Generally, a V/STOL aircraft needs to be able to hover. Helicopters are not considered under the V/STOL classification as the classification is only used for aeroplanes, aircraft that achieve lift in forward flight by planing the air, thereby achieving speed and fuel efficiency that is typically greater than the capability of helicopters.
