Vertical Takeoff and Landing (VTOL)

A vertical take-off and landing (VTOL) aircraft is one that can hover, take off, and land vertically. This classification can include a variety of types of aircraft including fixed-wing aircraft as well as helicopters and other aircraft with powered rotors, such as cyclogyros/cyclocopters and tiltrotors.

Electric and hybrid-electric vertical takeoff and landing aircraft, or eVTOLs, are being developed in the quest for fully autonomous passenger air vehicles (PAV).
