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.

Includes a fully-functional VC, 15 March 1993 28 years ago ( ) with Lufthansa & Air France. This is one of the most emblematic planes of the Argentinian company, and has been in service since 1999, one of the few A340-200 that were ever produced and are still flying.It was a smaller aircraft that would be developed into the long-range Airbus A310. A tenth variation, conceived in 1973, later the first to be constructed, was designated the A300B10. Prior to the service introduction of the first Airbus airliners, Airbus had identified nine possible variations of the A300 known as A300B1 to B9. From the moment of formation, Airbus had begun studies into derivatives of the Airbus A300B in support of this long-term goal. As of April 2020, it continues to operate 24 aircraft.Compared to the A340 quadjet (flying), the lighter A330 (on ground) has two engines and no centre-line wheel bogieWhen Airbus designed the Airbus A300 during the 1970s it envisioned a broad family of airliners to compete against Boeing and McDonnell Douglas, two established US aerospace manufacturers. Lufthansa is the largest operator and the largest customer with 62 aircraft in total.The A300B11 was joined by another design, the A300B9, which was a larger derivative of the A300. It was deemed a replacement for the less-efficient Boeing 707s and Douglas DC-8s still in service. Using four engines, it would seat between 180 and 200 passengers, and have a range of 11,000 kilometres (6,000 nmi). As the SA or "single aisle" studies (which later became the successful Airbus A320) underwent development to challenge the successful Boeing 737 and Douglas DC-9 in the single-aisle, narrow-body airliner market, Airbus turned its focus back to the wide-body aircraft market.The A300B11, a derivative of the A310, was designed upon the availability of "ten ton" thrust engines. The decision to work on the A320, instead of a four-engine aircraft proposed by the Germans, created divisions within Airbus.
The B9 was therefore considered a replacement for the DC-10 and the Lockheed L-1011 Tristar. The B9 offered the same range and payload as the McDonnell Douglas DC-10, but it used between 25% to 38% less fuel. It was targeted at the growing demand for high-capacity, medium-range, transcontinental trunk routes. It was essentially a stretched A300 with the same wing, coupled with the most powerful turbofan engine available at the time. Free roofing softwareIn Europe, opinion was split between the two. Airbus vice president for strategic planning, Adam Brown, recalled,North American operators were clearly in favour of a twin, while Asians wanted a quad. Another factor was the split preference of those within Airbus and, more importantly, prospective airliner customers. The adoption of a common wing structure also had one technical advantage: the TA11's outboard engines could counteract the weight of the longer-range model by providing bending relief. In an effort to save development costs, it was decided that the two would share the same wing and airframe the projected savings were estimated at US$500 million (about £490 million or €495 million). ![]() A340 800 Series Allowed OperatorsAirbus estimated this would yield a 2% improvement in aerodynamic efficiency. Studies were carried out by British Aerospace (BAe) at Hatfield and Bristol. Components were modular and also interchangeable with other Airbus aircraft where possible to reduce production, maintenance and operating costs.The A330/A340 shares a common flight deck with the A320.Airbus briefly considered a variable camber wing the concept was that the wing could change its profile to produce the optimum shape for a given phase of flight. The TA11 and TA12 would use the front and rear fuselage sections of the A310. Adopting a common cockpit across the new Airbus series allowed operators to make significant cost savings flight crews would be able to transition from one to another after one week of training. ![]() The later, longer-range versions, namely the A340-500 and -600, are powered by Rolls-Royce Trent 500 engines.On 27 January 1986, the Airbus Industrie Supervisory Board held a meeting in Munich, West Germany, after which board-chairman Franz Josef Strauß released a statement, "Airbus Industrie is now in a position to finalise the detailed technical definition of the TA9, which is now officially designated the A330, and the TA11, now called the A340, with potential launch customer airlines, and to discuss with them the terms and conditions for launch commitments". As a result of the superfan cancellation by IAE, the CFM56-5C4 was used as the sole engine choice instead of there being an alternate option as originally envisioned. The engine nacelles of the superfan engine consisted of provisions to allow a large fan near the rear of the engine.
