The Airbus A340 is a long-range, four-engine, wide-body commercial passenger jet airliner developed and produced by Airbus. The A340 was assembled at Toulouse, France. It seats up to 375 passengers in the standard variants and 440 in the stretched -600 series. Depending on the model, it has a range of between 6,700 to 9,000 nautical miles (12,400 to 16,700 km). The A340 is similar in design to the twin-engined A330 with which it was concurrently designed. Its distinguishing features are four high-bypass turbofan engines and three-bogie main landing gears.
Airbus manufactured the A340 in four fuselage lengths. The initial variant, A340-300, which entered service in 1993, measured 59.39 metres (194.8 ft). The shorter -200 was developed next, and the A340-600 was a 15.91 metres (52.2 ft) stretch of the -200. The -600 was developed alongside the shorter A340-500, which would become the longest-ranged commercial airliner until the arrival of the Boeing 777-200LR. The two initial models were powered by the CFM56-5C, rated at 151 kilonewtons (34,000 lbf), while Rolls-Royce held exclusive powerplant rights to the extended-ranged and heavier -500 and -600 models, through the 267-kilonewton (60,000 lbf) Rolls-Royce Trent 500. The initial A340-200 and -300 variants share the fuselageand wing of the A330, while the -500 and -600 are longer and have larger wings.[4]
Launch customers Lufthansa and Air France placed the A340 into service in March 1993. As of September 2011, 379 orders had been placed (not including private operators), of which 375 were delivered. The most common type were the A340-300 model, with 218 aircraft delivered. Lufthansa is the biggest operator of the A340, having acquired 59 aircraft. The A340 is used on long-haul, trans-oceanic routes due to its immunity from ETOPS; however, with reliability and fuel efficiency in engines improving, airlines are starting to phase out the type in favour of more economical twinjets, such as the A330 and the Boeing 777. Airbus announced on 10 November 2011 that A340 production had been concluded. The A340 is to be succeeded by larger variants of the Airbus A350.
