Airbus is a European multinational aerospace corporation founded in 1970. In 2019, Airbus was the world's largest airliner manufacturer and took the most airliner orders.
Airbus is registered in the Netherlands; its shares are traded in France, Germany and Spain. It designs, manufactures and sells civil and military aerospace products worldwide and manufactures aircraft in the European Union and various other countries.
The company's main civil aeroplane business is conducted through the French company Airbus S.A.S., based in Blagnac, a suburb of Toulouse, with production and manufacturing facilities mostly in Europe (France, Germany, Spain, United Kingdom) but also in China, the United States and Canada.
Final assembly production is based in Toulouse, France; Hamburg, Germany; Seville, Spain; Tianjin, China; Mobile, United States; and Montreal, Canada. The company produces and markets the first commercially viable digital fly-by-wire airliner, the Airbus A320, and the world's largest passenger airliner, the A380.
Fly-by-wire (FBW) is a system that replaces the conventional manual flight controls of an aircraft with an electronic interface. The movements of flight controls are converted to electronic signals transmitted by wires (hence the fly-by-wire term) and flight control computers determine how to move the actuators at each control surface to provide the ordered response. It can use mechanical flight control backup systems (like the Boeing 777) or use fully fly-by-wire controls.
