A powered lift aircraft takes off and lands vertically under engine power but uses a fixed wing for horizontal flight. Like helicopters , these aircraft do not need a long runway to take off and land, but they have a speed and performance similar to standard fixed-wing aircraft in combat or other situations.
The FAA classifies the Osprey as a model of powered lift aircraft. [15] Attempts were made in the 1960s to develop a commercial passenger aircraft with VTOL capability. The Hawker Siddeley Inter-City Vertical-Lift proposal had two rows of lifting fans on either side. However, none of these aircraft made it to production after they were ...
Powered lift; Gliders; Lighter than air; Powered parachute; Weight-shift control; Aircraft categories are also defined with respect to the certification of aircraft, to mean "a grouping of aircraft based upon intended use or operating limitations." Examples include transport, normal, utility, acrobatic, limited, restricted, and provisional. [3]
"The opportunities for the use of powered lift operations are far-reaching, from transporting passengers in urban areas and short-haul operations such as air ambulance services and cargo ...
The FAA defines a light sport aircraft as an aircraft, other than a helicopter or powered lift, that since its original certification, has continued to meet the following: [6] Max. gross takeoff weight: 1,320 lbs (600 kg) or 1,430 lbs for seaplanes (650 kg) Max. stall speed: 45 knots (83 km/h; 52 mph) CAS
The charts show the added lift benefit produced by ground effect. [3] For fan and jet-powered vertical take-off and landing (VTOL) aircraft, ground effect when hovering can cause suckdown and fountain lift on the airframe and loss in hovering thrust if the engine sucks in its own exhaust gas, which is known as hot gas ingestion (HGI).

An airline transport pilot implicitly holds an instrument rating, so the instrument rating does not appear on an ATP certificate. The FAA issues instrument ratings separately for airplane and powered lift categories and the helicopter class (INSTA and INSTH). [1]
The FAA defines a powered parachute as a powered aircraft comprised of a flexible or semi-rigid wing connected to a fuselage so that the wing is not in position for flight until the aircraft is in motion. The fuselage of a powered parachute contains the aircraft engine, a seat for each occupant and is attached to the aircraft's landing gear. [1]
