Description

 

   The Airbus A340 is a long-range, wide-body commercial 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.

     Keeping the eight-abreast economy cross-section of the A300, the early A340-200/300 has a similar airframe to the A330. 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. Both airliners have fly-by-wire controls, which was first introduced on the A320, as well as a similar glass cockpit. The later A340-500/600 have a larger wing and are powered by 275 kN (62,000 lbf) Rolls-Royce Trent 500 for a heavier 380 t (840,000 lb) MTOW.

     The shortest A340-200 measured 59.4 m (195 ft), and could cover 12,400 km / 6,700 nmi with 210-250 seats in 3-class. The most common A340-300 reached 63.7 m (209 ft) to accommodate 250-290 passengers and had a 13,500 km / 7,300 nmi range. The A340-500 was 67.9 m (223 ft) long to seat 270-310 over 16,670 km / 9,000 nmi, the longest-range airliner at the time. The longest A340-600 was stretched to 75.4 m (247 ft), then the longest airliner, to accommodate 320-370 passengers over 14,450 km / 7,800 nmi.

     As improving engine reliability allowed ETOPS operations for almost all routes, more economical twinjets have replaced quadjets on many routes. On 10 November 2011, Airbus announced that the production reached its end, after 380 orders have been placed and 377 of these have been delivered from Toulouse, France. The A350 XWB is its successor; the MD-11 and the Boeing 777 were its main competitors. Lufthansa is the largest operator and the largest customer with 62 aircraft in total. As of April 2020, it continues to operate 24 aircraft.

 A340 variants

There are four variants of the A340. The A340-200 and A340-300 were launched in 1987 with introduction into service in March 1993 for the -200. The A340-500 and A340-600 were launched in 1997 with introduction into service in 2002. All variants were available in a corporate version.

A340-200

The -200 is one of two initial versions of the A340; it has seating for 261 passengers in a three-class cabin layout with a range of 13,800 kilometres (7,500 nmi) or seating for 240 passengers also in a three-class cabin layout for a range of 15,000 kilometres (8,100 nmi). This is the shortest version of the family and the only version with a wingspan measuring greater than its fuselage length. It is powered by four CFMI CFM56-5C4 engines and uses the Honeywell 331–350[A] auxiliary power unit (APU). It initially entered service with Air France in May 1993. Due to its large wingspan, four engines, low capacity and improvements to the larger A340-300, the -200 proved heavy and unpopular with mainstream airlines. Only 28 A340-200s were produced. The closest Boeing competitor is the Boeing 767-400ER.

One version of this type (referred to by Airbus as the A340-8000) was ordered by the prince Jefri Bolkiah requesting a non-stop range of 15,000 kilometres (8,100 nmi). This A340-8000, in the Royal Brunei Airlines livery had an increased fuel capacity, an MTOW of 275 tonnes (606,000 lb), similar to the A340-300, and minor reinforcements to the undercarriage. It is powered by the 150 kilonewtons (34,000 lbf) thrust CFM56-5C4s similar to the -300E. Only one A340-8000 was produced. Besides the -8000, some A340-200s are used for VIP or military use; users include Royal Brunei Airlines, Qatar Amiri Flight, Arab Republic of Egypt Government, Royal Saudi Air Force, Jordan and the French Air Force. Following the -8000, other A340-200s were later given performance improvement packages (PIPs) that helped them achieve similar gains in capability as to the A340-8000. Those aircraft are labeled A340-213X. The range for this version is 15,000 kilometres (8,100 nmi).

As of April 2020, all active remaining A340-200s still flying are VIP or government planes, except the sole A340-200 operated by Conviasa. This aircraft is also the last A340-200 in commercial airline service.

A340-300

The A340-300 flies 295 passengers in a typical three-class cabin layout over 6,700 nautical miles (12,400 km). This is the initial version, having flown on 25 October 1991, and entered service with Lufthansa and Air France in March 1993. It is powered by four CFMI CFM56-5C engines and uses the Honeywell 331–350[A] APU, similar to the -200. The A340-300 is superseded by the A350-900. Its closest competitor is the Boeing 777-200ER.A total of 218 -300s were delivered.

The A340-300E, often mislabelled as A340-300X, has an increased MTOW of up to 275 tonnes (606,000 lb) and is powered by the more powerful 34,000 lbf (150 kN) thrust CFMI CFM56-5C4 engines. Typical range with 295 passengers is between 7,200 to 7,400 nautical miles (13,300 to 13,700 km). The largest operator of this type is Lufthansa, who has operated a fleet of 30 aircraft. The A340-300 Enhanced is the latest version of this model and was first delivered to South African Airways in 2003, with Air Mauritius receiving the A340-300 Enhanced into its fleet in 2006. It received newer CFM56-5C4/P engines and improved avionics and fly-by-wire systems developed for the A340-500 and -600.

As of July 2018, there were 96 Airbus A340-300s in airline service.

A340-500

Slightly longer than the -300, the -500 has a larger wing, larger Trent 500 turbofans and three 4-wheel bogies for the main landing gear, it was introduced by Emirates in 2003.

When the A340-500 was introduced, it was the world's longest-range commercial airliner. It first flew on 11 February 2002 and was certified on 3 December 2002. Air Canada was supposed to be the launch customer, but filed for bankruptcy in January 2003, delaying delivery to March. This allowed early deliveries to the new launch customer, Emirates, allowing the carrier to launch nonstop service from Dubai to New York—its first route in the Americas. The A340-500 can fly 313 passengers in a three-class cabin layout over 16020 km (8650 nm). Compared with the A340-300, the -500 features a 4.3-metre (14.1 ft) fuselage stretch, an enlarged wing, significant increase in fuel capacity (around 50% over the -300), slightly higher cruising speed, a larger horizontal stabilizer and a larger vertical tailplane. The centerline main landing gear was changed to a four-wheel bogie to support the additional weight. The A340-500 is powered by four 240 kN (54,000 lbf) thrust Rolls-Royce Trent 553 turbofans and uses the Honeywell 331–600[A] APU.

Designed for ultra long-haul routes, the -500 has a range of 9,000 nautical miles, where the Boeing 777-200LR have an 8,555 nmi range,[114] 445 fewer. Due to its range, the -500 is capable of travelling non-stop from London to Perth, Western Australia, though a return flight requires a fuel stop due to headwinds.[115] Singapore Airlines used this model (initially in a two-class 181-passenger layout, later in a 100-passenger business-only layout) between early 2004 and late 2013 for its Newark–Singapore and Singapore–Newark nonstop routes SQ21 and SQ22. The former was an 18-hour, 45-minute 'westbound' (actually a polar route northbound to 130 km (70 nm) abeam the North Pole, then south across Russia, Mongolia and the People's Republic of China) and the latter was an 18-hour, 30-minute eastbound, 15,344 kilometres (8,285 nmi) journey. At the time, the flight was the longest scheduled non-stop commercial flight in the world. Singapore Airlines even added a special compartment to the aircraft to store a corpse if a passenger were to die during the flight, though it was reported it had not been necessary. Singapore Airlines suspended operating the flight from 2013 onwards partly due to high fuel prices then and returned its aircraft to Airbus in exchange for ordering new Airbus A350 aircraft.[116] The SQ21/SQ22 route was eventually resumed, flown by A350-900ULR aircraft.

The A340-500IGW (Increased Gross Weight) version has a range of 17,000 km (9,200 nmi) and a MTOW of 380 t (840,000 lb) and first flew on 13 October 2006. It uses the strengthened structure and enlarged fuel capacity of the A340-600. The certification aircraft, a de-rated A340-541 model, became the first delivery, to Thai Airways International, on 11 April 2007. Nigerian airline Arik Air received a pair of A340-542s in November 2008, using the type to immediately launch two new routes, Lagos–London Heathrow and Lagos–Johannesburg; a non-stop Lagos–New York route began in January 2010. The A340-500IGW is powered by four 250 kN (56,000 lbf) thrust Rolls-Royce Trent 556 turbofans.

Like the A340-200, a shortened derivative of the -300, the -500 was unpopular. The -500 series was considered "very inefficient for how few seats they have because they still carry most of the guts of the larger airplanes [the A340-600] from which they were shrunk". Also the ultra long-haul market was a niche that was difficult to profit from, due to the amount of fuel that had to be carried. In addition, the -500 could not meet its maximum range without carrying a reduced load of passengers, so several operators reconfigured their -500s from a mix of business and premium economy to an all-business-class with 100 seats.[citation needed] As of March 2020, there were 2 A340-500s in airline service, both with Azerbaijan Airlines.

A340-600

Designed to replace early-generation Boeing 747 airliners, the A340-600 is capable of carrying 379 passengers in a three-class cabin layout 13,900 km (7,500 nmi). It provides similar passenger capacity to a 747 but with 25 percent more cargo volume, and at lower trip and seat costs. The first flight of the A340-600 was made on 23 April 2001.[124] Virgin Atlantic began commercial services in August 2002. The variant's main competitor is the 777-300ER. The A340-600 was replaced by the A350-1000.

The A340-600 is 12 m (39 ft 4.4 in) longer than a -300, more than 4 m (13 ft 1.5 in) longer than the Boeing 747-400 and 2.3 m (7 ft 6.6 in) longer than the A380, and has two emergency exit doors added over the wings. It held the record for the world's longest commercial aircraft until the first flight of the Boeing 747-8 in February 2010. The A340-600 is powered by four 250 kN (56,000 lbf) thrust Rolls-Royce Trent 556 turbofans and uses the Honeywell 331–600[A] APU. As with the -500, it has a four-wheel undercarriage bogie on the fuselage centre-line to cope with the increased MTOW along with the enlarged wing and rear empennage. Upper deck main cabin space can be optionally increased by locating facilities such as crew rest areas, galleys, and lavatories upon the aircraft's lower deck. In early 2007, Airbus reportedly advised carriers to reduce cargo in the forward section by 5.0 t (11,000 lb) to compensate for overweight first and business class sections; the additional weight caused the aircraft's centre of gravity to move forward thus reduce g cruise efficiency. Affected airlines considered filing compensation claims with Airbus.

The A340-600HGW (High Gross Weight) version first flew on 18 November 2005 and was certified on 14 April 2006. It has an MTOW of 380 t (840,000 lb) and a range of up to 14,630 km (7,900 nmi), made possible by strengthened structure, increased fuel capacity, more powerful engines and new manufacturing techniques like laser beam welding. The A340-600HGW is powered by four 61,900 lbf (275 kN) thrust Rolls-Royce Trent 560 turbofans. Emirates became the launch customer for the -600HGW when it ordered 18 at the 2003 Paris Air Show; but postponed its order indefinitely and later cancelled. Rival Qatar Airways, which placed its order at the same airshow, took delivery of only four aircraft with the first aircraft on 11 September 2006. The airline has since let its purchase options expire in favour of orders for the Boeing 777-300ER.

As of July 2018, there were 60 A340-600s in service with six airlines worldwide
