A340-200
The Airbus A340 is a long-range, wide-body passenger airliner that was developed and produced by 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 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 ...

Airbus A330
The Airbus A330 is a wide-body aircraft developed and produced by Airbus. Airbus conceived several derivatives of the A300, its first airliner in the mid-1970s. Then the company began development on the A330 twinjet in parallel with the A340 quadjet and launched both designs with their first orders in June 1987. The A330-300, the first variant, took its maiden flight in November 1992 and entered service with Air Inter in January 1994. The slightly shorter A330-200 variant followed in 1998. The A330 shares its airframe with the early A340 variants, having two main landing gear legs instead of three, lower weights, and slightly different lengths. Both airliners have fly-by-wire controls as well as a similar glass cockpit to increase the commonality. The A330 was Airbus's first airliner to offer a choice of three engines: the General Electric CF6, Pratt & Whitney PW4000, or the Rolls-Royce Trent 700. The A330-300 has a range of 11,750 km or 6,350 nmi with 277 passen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wide-body Aircraft
A wide-body aircraft, also known as a twin-aisle aircraft, is an airliner with a fuselage wide enough to accommodate two passenger aisles with seven or more seats abreast. The typical fuselage diameter is . In the typical wide-body economy cabin, passengers are seated seven to ten abreast, allowing a total capacity of 200 to 850 passengers. The largest wide-body aircraft are over wide, and can accommodate up to eleven passengers abreast in high-density configurations. By comparison, a typical narrow-body airliner has a diameter of , with a single aisle, and seats between two and six people abreast. Wide-body aircraft were originally designed for a combination of efficiency and passenger comfort and to increase the amount of cargo space. However, airlines quickly gave in to economic factors, and reduced the extra passenger space in order to insert more seats and increase revenue and profits. Wide-body aircraft are also used for the transport of commercial freight and cargo and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CFM56
The CFM International CFM56 (U.S. military designation F108) series is a Franco-American family of high-bypass turbofan aircraft engines made by CFM International (CFMI), with a thrust range of . CFMI is a 50–50 joint-owned company of Safran Aircraft Engines (formerly known as Snecma) of France, and GE Aviation (GE) of the United States. Both companies are responsible for producing components and each has its own final assembly line. GE produces the high-pressure compressor, combustor, and high-pressure turbine, Safran manufactures the fan, gearbox, exhaust and the low-pressure turbine, and some components are made by Avio of Italy and Honeywell from the US. The engines are assembled by GE in Evendale, Ohio, and by Safran in Villaroche, France. The completed engines are marketed by CFMI. Despite initial export restrictions, it is the most used turbofan aircraft engine in the world, in four major variants. The CFM56 first ran in 1974.Bilien, J. and Matta, R. (1989). ''The CFM5 ...

Rolls-Royce Trent 500
The Rolls-Royce Trent 500 is a high-bypass turbofan produced by Rolls-Royce to power the larger A340-500/600 variants. It was selected in June 1997, first ran in May 1999, first flew in June 2000, and achieved certification on 15 December 2000. It entered service in July 2002 and 524 engines were delivered on-wing until the A340 production ended in 2011. Keeping the three spool architecture of the Trent family, it has the Trent 700's 2.47 m (97.5 in) fan and a Trent 800 core scaled down. It produces up to 275 kN (61,900 lbf) of thrust at take-off and has a bypass ratio up to 8.5:1 in cruise. Development In 1995, Airbus began considering an engine for two new long-range derivatives of its four-engined A340, the A340-500/600. The existing A340-200/300 was powered by CFM International CFM56 engines. However, the CFM56 was at the limit of its development capability, and would be unable to power the new A340-500/-600. In April 1996, Airbus signed an agreement with GE Aviation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

South African Airways
South African Airways (SAA) is the flag carrier airline of South Africa. Founded in 1934, the airline is headquartered in Airways Park at O. R. Tambo International Airport in Johannesburg and operated a hub-and-spoke network, serving ten destinations in Africa. The carrier joined Star Alliance in , making it the first African carrier to sign with one of the three major airline alliances. The airline entered voluntary business rescue in December 2019 as a result of many years of financial losses, and suspended all operations the following year. In June 2021, the government announced that in an attempt to revive the airline, it had entered into a partnership with the Takatso Consortium, which would hold a 51% controlling stake. The South African Civil Aviation Authority confirmed on 4 August 2021 that SAA's air operator's certificate had been reissued with an approved fleet of eight aircraft.

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

Turbofan
The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft engine, aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the ''turbo'' portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the ''fan'', a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together; engines that use more Propelling nozzle, jet thrust relative to fan thrust are ...

ETOPS
ETOPS () is an acronym for ''Extended-range Twin-engine Operations Performance Standards''—a special part of flight rules for one-engine-inoperative flight conditions. The International Civil Aviation Organization (ICAO) coined the acronym for twin-engine aircraft operation in airspace further than one hour from a diversion airport at the one-engine-inoperative cruise speed, over water or remote lands, or on routes previously restricted to three- and four-engine aircraft. History The first heavier-than-air, non-stop transatlantic flight was made in 1919, by John Alcock and Arthur Brown, in a twin-engine Vickers Vimy, from Newfoundland to Ireland in sixteen hours. By 1936 the Bureau of Air Commerce (the precursor to the FAA) restricted operations to within of an airport, regardless of the engine number, about 60 minutes with one engine inoperative. In 1953 the FAA "60-minute rule" restricted twin-engine aircraft to a 60-minute diversion area, based on the piston engine rel ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".
