AIRBUS A340
The Airbus A340 is a long-range, wide-body passenger Aeroplane designed and manufactured by Airbus. Airbus imagined various versions of the A300, its first aircraft, in the mid-1970s, and built the A340 quadjet alongside the A330 twinjet.
The Airbus A340 is a twin-aisle passenger aircraft with four turbofan jet engines that was the first long-range Airbus. It was created using technology features such as the A320 glass cockpit; it shares many components with the A330, including identical fly-by-wire control systems and wings. The four engine design avoids ETOPS requirements such as increased inspection frequency
The A340 features a low cantilever wing; the A340-200/300 wing is nearly identical to that of the A330, with both engine pylons employed, although the A330 only uses the inboard one. The two engines for each wing give a more evenly distributed weight as well as a more outboard engine weight.
The first A340, a 200, was delivered to Lufthansa on February 2, 1993, and went into service on March 15, 1993. The aeroplane with 228 seats was called Nürnberg.On February 26, Air France received the 1000th Airbus A340-300, the first of nine anticipated to be operational by the end of the year. Air France replaced its Boeing 747s with A340s on its four-times-weekly Paris–Washington D.C. service. Lufthansa planned to replace aged DC-10s on Frankfurt–New York flights with A340s.
The A340 employs a modified A320 glass cockpit with side-stick controls rather than a traditional yoke. Six screens dominate the primary instrument panel, originally cathode ray tube monitors and eventually liquid crystal displays.The Electronic Flight Instrument System (EFIS) directs flight information, whereas the Electronic Centralised Aircraft Monitor directs system information (ECAM).
The aircraft monitors multiple sensors and informs the crew if any parameters are outside of their typical range; pilots may also analyse specific systems. Instead of paper instructions, electronic manuals are utilised, with optional web-based updates. Maintenance difficulties and expense were cut in half compared to the previous and smaller Airbus A310.Improved engine control and monitoring resulted in more time on the wing. The centralised maintenance computer can send real-time data to ground facilities.Heavy maintenance, such as structural upgrades, remained intact, but cabin sophistication, such as in-flight entertainment, was improved over previous airliners.
The A340 features a low cantilever wing; the A340-200/300 wing is nearly identical to that of the A330, with both engine pylons employed, although the A330 only uses the inboard one. The two engines for each wing offer a more evenly distributed weight, as well as a more outboard engine weight for a lower wing root bending moment at equal TOW, allowing a higher wing limitation MTOW for greater range. BAe designed and built the wings, which featured a long, narrow wing with a high aspect ratio for increased aerodynamic performance.
