Both airliners have fly-by-wire controls, which was first introduced on the A320, as well as a similar glass cockpit. Differences include four 151 kN (34,000 lbf) CFM56s instead of two high-thrust turbofans to bypass ETOPS restrictions on trans-oceanic routes, and a three-leg main landing gear instead of two for a heavier 276 t (608,000 lb) MTOW. Keeping the eight-abreast economy cross-section of the A300, the early A340-200/300 has a similar airframe to the A330.
The larger A340-500/600 were launched on 8 December 1997 the A340-600 flew for the first time on 23 April 2001 and entered service on 1 August 2002. It was certified along with the A340-200 on 22 December 1992 and both versions entered service in March 1993 with launch customers Lufthansa and Air France.
In June 1987, Airbus launched both designs with their first orders and the A340-300 took its maiden flight on 25 October 1991. In the mid-1970s, Airbus conceived several derivatives of the A300, its first airliner, and developed the A340 quadjet in parallel with the A330 twinjet. The Airbus A340 is a long-range, wide-body passenger airliner that was developed and produced by Airbus. 15 March 1993 30 years ago ( ) with Lufthansa & Air France
