Airbus A330 is a large-capacity, wide-body, twin-engine, medium-to-long-range commercial passenger airliner. It was developed at the same time as the four-engined Airbus A340, and will likely be replaced by the Airbus A350.
Design and development
Airbus intended the A330 to compete directly in the ETOPS (Extended-range Twin-engine Operation Performance Standards) market, specifically with the Boeing 767. The A330 first entered service in 1987; airlines purchased it to replace the McDonnell Douglas DC-10. The A330 is 38% more fuel efficient than the DC-10.
The A330's fuselage and wings are virtually identical to those of the smaller A340 variants, although it has different engines. The A330 basic fuselage design is inherited from the Airbus A300, and the nose/cockpit section and the fly-by-wire system and flightdeck are inherited from the A320. Both the A330 and A340 are assembled on the same final assembly line at Toulouse-Blagnac, France.
