Airbus A340 Wide-body " "1991"

The Airbus A340 is a long-range, wide-body passenger jet airliner that was developed and produced by the European aerospace company Airbus. 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. In June 1987, Airbus launched both designs with their first orders and the A340-300 took its maiden flight on 25 October 1991. 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. 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.

Design

The Airbus A340 is a twin-aisle passenger airliner, the first long-range Airbus,[67] powered by four turbofan jet engines.[68] It was developed upon earlier Airbus aircraft and their features like the A320 glass cockpit; it shares many components with the A330, notably identical fly-by-wire control systems and similar wings.[16][69] Its features and improvements were usually shared with the A330.[70] The four engines configuration avoided the ETOPS constraints such as more frequent inspections.

The A340 has a low cantilever wing; the A340-200/300 wing is virtually identical to that of the A330, with both engine pylons used while only the inboard one is used on the A330. The two engines for each wing provide a more distributed weight; and a more outboard engine weight for a lower wing root bending moment at equal TOW, allowing a higher wing limited MTOW for more range

In 1991, the A340-400X was a simple 12-frame, 20 ft 10 in (6.35 m) -300 stretch from 295 to 335 passengers with the MTOW bumped from 553,360 to 588,600 lb (251 to 267 t) and the range decreased by 1,390 to 10,930 km (750 to 5,900 nmi).[42] CFM International was then set to develop for $1–1.5 billion a new engine between the 150 kN (34,000 lbf) CFM56 and the 315–400 kN (70–90,000 lbf) GE90.[43] In 1994, Airbus was studying a heavier A340 Advanced with a reinforced wing and 178 kN (40,000 lbf) engines: the Pratt & Whitney advanced ducted propulsor, CFM International CFMXX or Rolls Royce RB411, to allow from 1996 a -300 stretch for 50 more passengers over the same range, a -300 with the -200 range and a -200 with more range.[44] In 1995, the A340-400 was slated for 2000, seating 380 passengers with a 300 t (660,000 lb) take-off weight.
