<span class="mw-page-title-main">Cessna</span> Aircraft manufacturing subsidiary of Textron

Cessna is an American brand of general aviation aircraft owned by Textron Aviation since 2014, headquartered in Wichita, Kansas. Originally, it was a brand of the Cessna Aircraft Company, an American general aviation aircraft manufacturing corporation also headquartered in Wichita. The company produced small, piston-powered aircraft, as well as business jets. For much of the mid-to-late 20th century, Cessna was one of the highest-volume and most diverse producers of general aviation aircraft in the world. It was founded in 1927 by Clyde Cessna and Victor Roos and was purchased by General Dynamics in 1985, then by Textron, Inc. in 1992. In March 2014, when Textron purchased the Beechcraft and Hawker Aircraft corporations, Cessna ceased operations as a subsidiary company, and joined the others as one of the three distinct brands produced by Textron Aviation.

<span class="mw-page-title-main">VTOL</span> Aircraft takeoff and landing done vertically

A vertical take-off and landing (VTOL) aircraft is one that can take off and land vertically without relying on a runway. This classification can include a variety of types of aircraft including helicopters as well as thrust-vectoring fixed-wing aircraft and other hybrid aircraft with powered rotors such as cyclogyros/cyclocopters and gyrodynes.

<span class="mw-page-title-main">Ultralight aviation</span> Aviation field involving lightweight aircraft

Ultralight aviation is the flying of lightweight, 1- or 2-seat fixed-wing aircraft. Some countries differentiate between weight-shift control and conventional three-axis control aircraft with ailerons, elevator and rudder, calling the former "microlight" and the latter "ultralight".

<span class="mw-page-title-main">AeroVironment</span> American unmanned aerial vehicle manufacturer

AeroVironment, Inc. is an American defense contractor headquartered in Arlington, Virginia, that designs and manufactures unmanned aerial vehicles (UAVs). Paul B. MacCready Jr., a designer of human-powered aircraft, founded the company in 1971. The company is best known for its lightweight human-powered and solar-powered vehicles. The company is the US military's top supplier of small drones —notably the Raven, Switchblade, Wasp and Puma models.

<span class="mw-page-title-main">Sonex Aircraft Sonex</span>

The Onex, Sonex, Waiex and Xenos are a family of lightweight, metal, low-wing, two seat homebuilt aircraft. Kits are produced and marketed by Sonex Aircraft, a small manufacturer based in Oshkosh, Wisconsin. By 2014, 500 customer built aircraft had been completed. The Sonex can also be built from plans.

<span class="mw-page-title-main">Personal air vehicle</span> Type of aircraft

A personal air vehicle (PAV) is a proposed class of passenger aircraft providing on-demand air transport.

<span class="mw-page-title-main">Electric aircraft</span> Aircraft powered directly by electricity, with no other engine needed

An electric aircraft is an aircraft powered by electricity. Electric aircraft are seen as a way to reduce the environmental effects of aviation, providing zero emissions and quieter flights. Electricity may be supplied by a variety of methods, the most common being batteries. Most have electric motors driving propellers or turbines.

Pipistrel d.o.o Ajdovščina is a Slovenian light aircraft manufacturer established in 1989 by Ivo Boscarol and based in Ajdovščina. Its facilities are located in Ajdovščina, Slovenia, and near Gorizia, Italy. By March 2019, Pipistrel had produced more than 2000 aircraft.

The Electric Aircraft Corporation ElectraFlyer Trike is an ultralight trike fitted with an electric motor, instead of a traditional gasoline engine.

The Yuneec International E430 is a Chinese two-seat electric aircraft that was designed for commercial production by electric model aircraft manufacturer Yuneec International. The first flight of the E430 took place from the Yuneec factory near Shanghai, China on June 12, 2009.

<span class="mw-page-title-main">Pipistrel Taurus</span> Type of aircraft

<span class="mw-page-title-main">IFB-Stuttgart E-Genius</span> Type of aircraft

The e-Genius is a crewed electric airplane developed by the Institute of Aircraft Design at the University of Stuttgart, which first flew in May 2011.

Aircraft have different ways to take off and land. Conventional airplanes accelerate along the ground until reaching a speed that is sufficient for the airplane to takeoff and climb at a safe speed. Some airplanes can take off at low speed, this being a short takeoff. Some aircraft such as helicopters and Harrier jump jets can take off and land vertically. Rockets also usually take off vertically, but some designs can land horizontally.

<span class="mw-page-title-main">Pipistrel Alpha Trainer</span> Slovenian light-sport aircraft

The Pipistrel Alpha Trainer is a Slovenian two-seat, single-engine light-sport aircraft intended specifically for flight training, designed and produced by Pipistrel in Gorizia, Italy.

<span class="mw-page-title-main">Synergy Aircraft Synergy</span> Type of aircraft

The Synergy Aircraft Synergy is a proposed five-seat, single-engine, kit aircraft, designed by John McGinnis of Kalispell, Montana and intended for production by his company, Synergy Aircraft.

Urban air mobility (UAM) is the use of small, highly automated aircraft to carry passengers or cargo at lower altitudes in urban and suburban areas which have been developed in response to traffic congestion. It usually refers to existing and emerging technologies such as traditional helicopters, vertical-takeoff-and-landing aircraft (VTOL), electrically propelled vertical-takeoff-and-landing aircraft (eVTOL), and unmanned aerial vehicles (UAVs). These aircraft are characterized by the use of multiple electric-powered rotors or fans for lift and propulsion, along with fly-by-wire systems to control them. Inventors have explored urban air mobility concepts since the early days of powered flight. However, advances in materials, computerized flight controls, batteries and electric motors improved innovation and designs beginning in the late 2010s. Most UAM proponents envision that the aircraft will be owned and operated by professional operators, as with taxis, rather than by private individuals.

Bye Aerospace is an American aircraft manufacturer based in unincorporated Arapahoe County, Colorado. The company specializes in the design and manufacture of electric aircraft, including unmanned aircraft for geospatial role and light aircraft for the flight training role. The company was founded by George E. Bye, who remains the CEO.

<span class="mw-page-title-main">Joby Aviation</span> American aviation company

Joby Aviation is a United States venture-backed aviation company, developing an electric vertical takeoff and landing (eVTOL) aircraft that it intends to operate as an air taxi service. Joby Aviation is headquartered in Santa Cruz, California, and has offices in San Carlos, California; Marina, California; and Munich, Germany.

eVTOL Type of aircraft

An electric vertical take-off and landing (eVTOL) aircraft is a variety of VTOL aircraft that uses electric power to hover, take off, and land vertically. This technology came about owing to major advances in electric propulsion and the emerging need for new aerial vehicles for urban air mobility that can enable greener and quieter flights. Electric and hybrid propulsion systems (EHPS) have also the potential of lowering the operating costs of aircraft.
