A twinjet or twin-engine jet is a jet aircraft powered by two engines . A twinjet is able to fly well enough to land with a single working engine, making it safer than a single-engine aircraft in the event of failure of an engine. Fuel efficiency of a twinjet is better than that of aircraft with more engines. These considerations have led to the widespread use of aircraft of all types with twin engines, including airliners , fixed-wing military aircraft , and others.
160-578: The Airbus A300 is Airbus' first production aircraft and the world's first twin-engine , double-aisle (wide-body) airliner . It was developed by Airbus Industrie GIE , now merged into Airbus SE , and manufactured from 1971 to 2007. In September 1967, aircraft manufacturers in France , West Germany and the United Kingdom signed an initial memorandum of understanding to collaborate to develop an innovative large airliner. The French and West Germans reached
320-637: A Neutrality Pact in April 1941, and Japan adopted the doctrine of Nanshin-ron , promoted by the Navy, which took its focus southward and eventually led to war with the United States and the Western Allies. In Europe, Germany and Italy were becoming more aggressive. In March 1938, Germany annexed Austria , again provoking little response from other European powers. Encouraged, Hitler began pressing German claims on
480-564: A cautious French probe into the Saarland . The Western Allies also began a naval blockade of Germany , which aimed to damage the country's economy and war effort. Germany responded by ordering U-boat warfare against Allied merchant and warships, which would later escalate into the Battle of the Atlantic . On 8 September, German troops reached the suburbs of Warsaw . The Polish counter-offensive to
640-625: A great circle route. Hence, in case of an engine failure in a twinjet (like Boeing 777 ), the twin-jet could make emergency landings in fields in Canada , Alaska , eastern Russia , Greenland , Iceland , or the British Isles . The Boeing 777 has also been approved by the Federal Aviation Administration for flights between North America and Hawaii , which is the world's longest regular airline route with no diversion airports along
800-510: A podded engine usually mounted beneath, or occasionally above or within, each wing. Most notable examples of such a configuration are the Boeing 737 and Airbus A320 . The second has one engine mounted on each side of the rear fuselage, close to its empennage , used by many business jets , although some airliners like the Fokker 70 , Douglas DC-9 and COMAC ARJ21 utilise such a design as well. In
960-671: A firm agreement on 29 May 1969, after the British withdrew from the project on 10 April 1969. A new collaborative aerospace company , Airbus Industrie GIE , was formally created on 18 December 1970 to develop and produce it. The A300 prototype first flew on 28 October 1972. The first twin-engine widebody airliner, the A300 typically seats 247 passengers in two classes over a range of 5,375 to 7,500 km (2,900 to 4,050 nmi; 3,340 to 4,660 mi). Initial variants are powered by General Electric CF6-50 or Pratt & Whitney JT9D turbofans and have
1120-522: A flight deck upgrade based around Honeywell Primus Epic avionics; new displays and flight management system (FMS), improved weather radar , a central maintenance system, and a new version of the current enhanced ground proximity warning system . With a light usage of only two to three cycles per day, it will not reach the maximum number of cycles by then. The first modification will be made at Airbus Toulouse in 2019 and certified in 2020. As of July 2017, there are 211 A300s in service with 22 operators, with
1280-581: A further £35 million loan from the West German government, on the machine tooling to design and produce the wings. On 29 May 1969, during the Paris Air Show , French transport minister Jean Chamant and German economics minister Karl Schiller signed an agreement officially launching the Airbus A300, the world's first twin-engine widebody airliner. The intention of the project was to produce an aircraft that
1440-656: A high level of technology, which would serve as a decisive advantage over prospective competitors. For this reason, the A300 would feature the first use of composite materials of any passenger aircraft, the leading and trailing edges of the tail fin being composed of glass fibre reinforced plastic . Béteille opted for English as the working language for the developing aircraft, as well against using Metric instrumentation and measurements, as most airlines already had US-built aircraft. These decisions were partially influenced by feedback from various airlines, such as Air France and Lufthansa , as an emphasis had been placed on determining
1600-603: A high-lift system. This was done to improve performance when operating at high-altitude airports, where the air is less dense and lift generation is reduced. The variant had an increased MTOW of 142 t (313,000 lb) and was powered by CF6-50C engines, was certified on 23 June 1976, and entered service with South African Airways in November 1976. CF6-50C1 and CF6-50C2 models were also later fitted depending on customer requirements, these became certified on 22 February 1978 and 21 February 1980 respectively. The A300B2-320 introduced
1760-498: A multinational airliner project to invigorate its aircraft industry, which had declined considerably following the Second World War . During the mid-1960s, both Air France and American Airlines had expressed interest in a short-haul twin-engine wide-body aircraft , indicating a market demand for such an aircraft to be produced. In July 1967, during a high-profile meeting between French, German, and British ministers, an agreement

The United Kingdom responded with an ultimatum for Germany to cease military operations, and on 3 September, after the ultimatum was ignored, Britain and France declared war on Germany. During the Phoney War period, the alliance provided no direct military support to Poland, outside of
2080-715: A pretext to worsen relations. On 29 August, Hitler demanded that a Polish plenipotentiary immediately travel to Berlin to negotiate the handover of Danzig , and to allow a plebiscite in the Polish Corridor in which the German minority would vote on secession. The Poles refused to comply with the German demands, and on the night of 30–31 August in a confrontational meeting with the British ambassador Nevile Henderson , Ribbentrop declared that Germany considered its claims rejected. On 1 September 1939, Germany invaded Poland after having staged several false flag border incidents as
2240-520: A recambered trailing edge, the incorporation of simpler single-slotted Fowler flaps , the deletion of slat fences, and the removal of the outboard ailerons after they were deemed unnecessary on the A310. The variant made its first flight on 8 July 1983, was certified on 9 March 1984, and entered service in June 1984 with Saudi Arabian Airlines . A total of 313 A300-600s (all versions) have been sold. The A300-600 uses
2400-469: A secret protocol that defined German and Soviet "spheres of influence" (western Poland and Lithuania for Germany; eastern Poland , Finland, Estonia , Latvia and Bessarabia for the Soviet Union), and raised the question of continuing Polish independence. The pact neutralised the possibility of Soviet opposition to a campaign against Poland and assured that Germany would not have to face the prospect of
2560-521: A similar high-lift system to what was later fitted to the A300B2-200. The variant made its maiden flight on 26 December 1974, was certified on 26 March 1975, and entered service with Germanair in May 1975. The A300B4-200 had an increased MTOW of 165 tonnes (364,000 lb) and featured an additional optional fuel tank in the rear cargo hold, which would reduce the cargo capacity by two LD3 containers. The variant

The Soviet Union invaded Finland in November 1939, and was subsequently expelled from the League of Nations for this crime of aggression. Despite overwhelming numerical superiority, Soviet military success during the Winter War was modest, and the Finno-Soviet war ended in March 1940 with some Finnish concessions of territory . In June 1940,
2880-408: A specified distance from an available diversion airport. Overwater flights near diversion airports need not be ETOPS/LROPS-compliant. Since the 1990s, airlines have increasingly turned from four-engine or three-engine airliners to twin-engine airliners to operate transatlantic and transpacific flight routes. On a nonstop flight from America to Asia or Europe, the long-range aircraft usually follows
3040-420: A three-crew flight deck. The improved A300-600 has a two-crew cockpit and updated CF6-80C2 or PW4000 engines; it made its first flight on 8 July 1983 and entered service later that year. The A300 is the basis of the smaller A310 (first flown in 1982) and was adapted in a freighter version. Its cross section was retained for the larger four-engined A340 (1991) and the larger twin-engined A330 (1992). It

The MD-11's long range advantage was brief as it was soon nullified by the Airbus A330-300 and the extended-range Boeing 767-300ER and Boeing 777-200ER. The Airbus A320 twinjet stands out as the most produced jet airliner. The Boeing 777X is the world's largest twinjet, and
3360-519: A two-front war, as it had in World War I. Immediately afterwards, Hitler ordered the attack to proceed on 26 August, but upon hearing that the United Kingdom had concluded a formal mutual assistance pact with Poland and that Italy would maintain neutrality, he decided to delay it. In response to British requests for direct negotiations to avoid war, Germany made demands on Poland, which served as

Glass cockpit flight instrumentation, which used cathode-ray tube (CRT) monitors to display flight, navigation, and warning information, along with fully digital dual autopilots and digital flight control computers for controlling
3680-497: A vital market that was ready to be opened up and believed Korean Air to be the 'key'. Airlines operating the A300 on short-haul routes were forced to reduce frequencies to try and fill the aircraft. As a result, they lost passengers to airlines operating more frequent narrow-body flights. Eventually, Airbus had to build its own narrowbody aircraft (the A320 ) to compete with the Boeing 737 and McDonnell Douglas DC-9 / MD-80 . The saviour of
3840-424: Is also the basis for the oversize Beluga transport (1994). Unlike most Airbus products, it has a yoke , not using a fly-by-wire system. Launch customer Air France introduced the type on 23 May 1974. After limited demand initially, sales took off as the type was proven in early service, beginning three decades of steady orders. It has a similar capacity to the Boeing 767 -300, introduced in 1986, but lacked
4000-474: Is not an issue, as one of the engines is more than powerful enough to keep the aircraft aloft (see below). Mostly, ETOPS certification involves maintenance and design requirements ensuring that a failure of one engine cannot make the other one fail also. The engines and related systems need to be independent and (in essence) independently maintained. ETOPS/LROPS is often incorrectly thought to apply only to long overwater flights, but it applies to any flight more than
4160-408: Is powered by a pair of underwing turbofan engines, either General Electric CF6 or Pratt & Whitney JT9D engines; the sole use of underwing engine pods allowed for any suitable turbofan engine to be more readily used. The lack of a third tail-mounted engine, as per the trijet configuration used by some competing airliners, allowed for the wings to be located further forwards and to reduce the size of

Its advanced autopilots are capable of flying the aircraft from climb-out to landing, and it has an electrically controlled braking system. Later A300s incorporated other advanced features such as the Forward-Facing Crew Cockpit (FFCC), which enabled

It would have a 10-abreast economy like the 777; its 565 m (6,081 sq ft) wing, slightly more than the 747-8, would have an 80 m (262 ft) span, as wide as the A380 , for a 892,900 lb (405 t) MTOW compared to 775,000 lb (352 t) for
4640-588: The Anglo-German Naval Agreement and the German–Polish declaration of non-aggression . The situation became a crisis in late August as German troops continued to mobilise against the Polish border. On 23 August the Soviet Union signed a non-aggression pact with Germany, after tripartite negotiations for a military alliance between France, the United Kingdom, and Soviet Union had stalled. This pact had

The basic fuselage of the A300 was later stretched ( A330 and A340 ), shortened (A310), or modified into derivatives ( A300-600ST Beluga Super Transporter ). In 2006, unit cost of an −600F was $ 105 million. In March 2006, Airbus announced the impending closure of the A300/A310 final assembly line, making them
4960-399: The Boeing 777 , Boeing 787 and Airbus A350 have matched or surpassed older quad-jet designs such as the Boeing 747 and Airbus A340 in these aspects, and twinjets have been more successful in terms of sales than quad-jets. In 2012, Airbus studied a 470-seat twinjet competitor for the Boeing 747-8 with lower operating costs expected between 2023 and 2030, revived after Boeing launched

Soon the United Kingdom and France followed the appeasement policy of British Prime Minister Neville Chamberlain and conceded this territory to Germany in the Munich Agreement , which was made against the wishes of the Czechoslovak government, in exchange for a promise of no further territorial demands. Soon afterwards, Germany and Italy forced Czechoslovakia to cede additional territory to Hungary, and Poland annexed

Although all of Germany's stated demands had been satisfied by the agreement, privately Hitler was furious that British interference had prevented him from seizing all of Czechoslovakia in one operation. In subsequent speeches Hitler attacked British and Jewish "war-mongers" and in January 1939 secretly ordered a major build-up of the German navy to challenge British naval supremacy. In March 1939, Germany invaded

On 7 July 1978, the A310 (initially the A300B10) was launched with orders from Swissair and Lufthansa. On 3 April 1982, the first prototype conducted its maiden flight and it received its type certification on 11 March 1983. Keeping
10880-401: The Airbus consortium via British Aerospace , which Hawker Siddeley had merged into, which acquired a 20 per cent stake in Airbus Industrie with France and Germany each reducing their stakes to 37.9 per cent. Airbus Industrie was initially headquartered in Paris , which is where design, development, flight testing, sales, marketing, and customer support activities were centred; the headquarters
11040-409: The Allies were attempting to cut off . Denmark capitulated after six hours , and despite Allied support , Norway was conquered within two months. British discontent over the Norwegian campaign led to the resignation of Prime Minister Neville Chamberlain , who was replaced by Winston Churchill on 10 May 1940. On the same day, Germany launched an offensive against France . To circumvent
11200-400: The Axis war against the Soviet Union, in Romania's case partially to recapture territory ceded to the Soviet Union . In early June 1940, the Italian Regia Aeronautica attacked and besieged Malta , a British possession. From late summer to early autumn, Italy conquered British Somaliland and made an incursion into British-held Egypt . In October, Italy attacked Greece , but the attack
11360-421: The Blitz , but largely ended in May 1941 after failing to significantly disrupt the British war effort. Using newly captured French ports, the German Navy enjoyed success against an over-extended Royal Navy , using U-boats against British shipping in the Atlantic . The British Home Fleet scored a significant victory on 27 May 1941 by sinking the German battleship Bismarck . In November 1939,
11520-645: The British Government's support for the Airbus, which coincided with its refusal to back BAC's proposed competitor, the BAC 2–11, despite a preference for the latter expressed by British European Airways (BEA). Another parameter was the requirement for a new engine to be developed by Rolls-Royce to power the proposed airliner; a derivative of the in-development Rolls-Royce RB211 , the triple-spool RB207, capable of producing of 47,500 lbf (211 kN). The programme cost
11680-659: The European Axis declaring war on the US. Japan conquered much of coastal China and Southeast Asia , but its advances in the Pacific were halted in mid-1942 after its defeat in the naval Battle of Midway ; Germany and Italy were defeated in North Africa and at Stalingrad in the Soviet Union. Key setbacks in 1943—including German defeats on the Eastern Front, the Allied invasions of Sicily and
11840-602: The FAA 60-minutes rule for twin-engine airliners which existed at the time, Asian airlines used A300s for routes across the Bay of Bengal and South China Sea . In 1977, the A300B4 became the first ETOPS compliant aircraft, qualifying for Extended Twin Engine Operations over water, providing operators with more versatility in routing. In 1982 Garuda Indonesia became the first airline to fly
12000-674: The French possessions of Syria and Lebanon , assisted by the Free French . With the situation in Europe and Asia relatively stable, Germany, Japan, and the Soviet Union made preparations for war. With the Soviets wary of mounting tensions with Germany, and the Japanese planning to take advantage of the European War by seizing resource-rich European possessions in Southeast Asia , the two powers signed
12160-480: The Germans, and the last large operational unit of the Polish Army surrendered on 6 October . Despite the military defeat, Poland never surrendered; instead, it formed the Polish government-in-exile and a clandestine state apparatus remained in occupied Poland. A significant part of Polish military personnel evacuated to Romania and Latvia; many of them later fought against the Axis in other theatres of
12320-505: The Nationalists. Both Germany and the Soviet Union used this proxy war as an opportunity to test in combat their most advanced weapons and tactics. The Nationalists won the civil war in April 1939; Franco, now dictator, remained officially neutral during World War II but generally favoured the Axis . His greatest collaboration with Germany was the sending of volunteers to fight on the Eastern Front . In July 1937, Japan captured
12480-487: The RB207's development had been slow for some time, the firm having suffered due to funding limitations, both of which had been factors in the engine switch decision. On 10 April 1969, a few months after the decision to drop the RB207 had been announced, the British government announced that they would withdraw from the Airbus venture. In response, West Germany proposed to France that they would be willing to contribute up to 50% of
12640-505: The Royal Navy putting three Italian battleships out of commission after a carrier attack at Taranto , and neutralising several more warships at the Battle of Cape Matapan . Italian defeats prompted Germany to deploy an expeditionary force to North Africa; at the end of March 1941, Rommel 's Afrika Korps launched an offensive which drove back Commonwealth forces. In less than a month, Axis forces advanced to western Egypt and besieged
12800-584: The Soviet Union occupied the entire territories of Estonia, Latvia and Lithuania, as well as the Romanian regions of Bessarabia, Northern Bukovina, and the Hertsa region . In August 1940, Hitler imposed the Second Vienna Award on Romania which led to the transfer of Northern Transylvania to Hungary. In September 1940, Bulgaria demanded Southern Dobruja from Romania with German and Italian support, leading to
12960-735: The Soviet Union , opening the Eastern Front and initially making large territorial gains. Japan aimed to dominate East Asia and the Asia-Pacific , and by 1937 was at war with the Republic of China . In December 1941, Japan attacked American and British territories in Southeast Asia and the Central Pacific , including Pearl Harbor in Hawaii , which resulted in the US and the UK declaring war against Japan, and
13120-520: The Soviet Union and Mongolia . The Japanese doctrine of Hokushin-ron , which emphasised Japan's expansion northward, was favoured by the Imperial Army during this time. This policy would prove difficult to maintain in light of the Japanese defeat at Khalkin Gol in 1939, the ongoing Second Sino-Japanese War and ally Nazi Germany pursuing neutrality with the Soviets. Japan and the Soviet Union eventually signed
13280-738: The Soviet Union should be eliminated and aimed for the conquest of Ukraine , the Baltic states and Byelorussia . However, other senior German officials like Ribbentrop saw an opportunity to create a Euro-Asian bloc against the British Empire by inviting the Soviet Union into the Tripartite Pact. In November 1940, negotiations took place to determine if the Soviet Union would join the pact. The Soviets showed some interest but asked for concessions from Finland, Bulgaria, Turkey, and Japan that Germany considered unacceptable. On 18 December 1940, Hitler issued
13440-700: The UK, and Sud Aviation of France, had ambitions to build a new 200-seat airliner for the growing civil aviation market. While studies were performed and considered, such as a stretched twin-engine variant of the Hawker Siddeley Trident and an expanded development of the British Aircraft Corporation (BAC) One-Eleven , designated the BAC Two-Eleven , it was recognized that if each of the European manufacturers were to launch similar aircraft into
13600-402: The US dropped the first atomic bombs on Hiroshima and Nagasaki on 6 and 9 August. Faced with an imminent invasion of the Japanese archipelago , the possibility of further atomic bombings, and the Soviet declaration of war against Japan and its invasion of Manchuria , Japan announced its unconditional surrender on 15 August and signed a surrender document on 2 September 1945 , marking
13760-568: The United Kingdom and France guaranteed their support for Polish independence ; when Italy conquered Albania in April 1939, the same guarantee was extended to the Kingdoms of Romania and Greece . Shortly after the Franco - British pledge to Poland, Germany and Italy formalised their own alliance with the Pact of Steel . Hitler accused the United Kingdom and Poland of trying to "encircle" Germany and renounced
13920-538: The United Kingdom attacked on 3 July in an attempt to prevent its seizure by Germany. The air Battle of Britain began in early July with Luftwaffe attacks on shipping and harbours . The German campaign for air superiority started in August but its failure to defeat RAF Fighter Command forced the indefinite postponement of the proposed German invasion of Britain . The German strategic bombing offensive intensified with night attacks on London and other cities in
14080-455: The United Kingdom. The Germans turned south against the weakened French army, and Paris fell to them on 14 June. Eight days later France signed an armistice with Germany ; it was divided into German and Italian occupation zones , and an unoccupied rump state under the Vichy Regime , which, though officially neutral, was generally aligned with Germany. France kept its fleet, which
14240-640: The United States was assisting China and the Western Allies, and had amended the Neutrality Act to allow "cash and carry" purchases by the Allies. In 1940, following the German capture of Paris, the size of the United States Navy was significantly increased . In September the United States further agreed to a trade of American destroyers for British bases . Still, a large majority of the American public continued to oppose any direct military intervention in
14400-590: The Yellow River ; this manoeuvre bought time for the Chinese to prepare their defences at Wuhan , but the city was taken by October. Japanese military victories did not bring about the collapse of Chinese resistance that Japan had hoped to achieve; instead, the Chinese government relocated inland to Chongqing and continued the war. In the mid-to-late 1930s, Japanese forces in Manchukuo had sporadic border clashes with
14560-451: The aging DC-9s and 727-100s but in smaller numbers, while being a twinjet sized between the Tristars and 727-200s, and capable of operating from short runway airports with sufficient range from New York City to Miami. Borman proceeded to order 23 A300s, becoming the first U.S. customer for the type. This order is often cited as the point at which Airbus came to be seen as a serious competitor to
14720-538: The aircraft the ability to climb faster and attain a level cruising altitude sooner than any other passenger aircraft. It was later renamed the A300B. Perhaps the most significant change of the A300B was that it would not require new engines to be developed, being of a suitable size to be powered by Rolls-Royce's RB211, or alternatively the American Pratt & Whitney JT9D and General Electric CF6 powerplants; this switch
14880-478: The airliner. The second prototype was leased to Trans European Airways in 1974. Responding to a need for more seats from Air France , Airbus decided that the first production variant should be larger than the original prototype A300B1. The CF6-50A powered A300B2-100 was 2.6 m (8.5 ft) longer than the A300B1 and had an increased MTOW of 137 t (302,000 lb), allowing for 30 additional seats and bringing
15040-456: The capital Nanking in December 1937. After the fall of Nanking, tens or hundreds of thousands of Chinese civilians and disarmed combatants were murdered by the Japanese . In March 1938, Nationalist Chinese forces won their first major victory at Taierzhuang , but then the city of Xuzhou was taken by the Japanese in May. In June 1938, Chinese forces stalled the Japanese advance by flooding
15200-598: The company had achieved a 26 per cent market share in terms of dollar value, enabling Airbus to proceed with the development of its second aircraft, the Airbus A310 . The Airbus A300 is a wide-body medium-to-long range airliner ; it has the distinction of being the first twin-engine wide-body aircraft in the world. In 1977, the A300 became the first Extended Range Twin Operations (ETOPS)-compliant aircraft, due to its high performance and safety standards. Another world-first of
15360-403: The conflict well into 1941. In December 1940, Roosevelt accused Hitler of planning world conquest and ruled out any negotiations as useless, calling for the United States to become an " arsenal of democracy " and promoting Lend-Lease programmes of military and humanitarian aid to support the British war effort; Lend-Lease was later extended to the other Allies, including the Soviet Union after it
15520-450: The consequences of this expedition, it had allegedly brought the A300 to the attention of Frank Borman , the CEO of Eastern Airlines , one of the "big four" U.S. airlines. On 15 March 1974, type certificates were granted for the A300 from both German and French authorities, clearing the way for its entry into revenue service. On 23 May 1974, Federal Aviation Administration (FAA) certification
15680-515: The creation of a " New Roman Empire ". Adolf Hitler , after an unsuccessful attempt to overthrow the German government in 1923, eventually became the Chancellor of Germany in 1933 when Paul von Hindenburg and the Reichstag appointed him. Following Hindenburg's death in 1934, Hitler proclaimed himself Führer of Germany and abolished democracy, espousing a radical, racially motivated revision of
15840-739: The dissolution of the Austro-Hungarian, Ottoman, and Russian Empires. To prevent a future world war, the League of Nations was established in 1920 by the Paris Peace Conference . The organisation's primary goals were to prevent armed conflict through collective security, military, and naval disarmament , as well as settling international disputes through peaceful negotiations and arbitration. Despite strong pacifist sentiment after World War I , irredentist and revanchist nationalism had emerged in several European states. These sentiments were especially marked in Germany because of
16000-637: The end of May completed the German conquest of the Balkans. Partisan warfare subsequently broke out against the Axis occupation of Yugoslavia , which continued until the end of the war. In the Middle East in May, Commonwealth forces quashed an uprising in Iraq which had been supported by German aircraft from bases within Vichy-controlled Syria . Between June and July, British-led forces invaded and occupied
16160-463: The end of the war. World War II changed the political alignment and social structure of the world, and it set the foundation of international relations for the rest of the 20th century and into the 21st century. The United Nations was established to foster international cooperation and prevent conflicts, with the victorious great powers—China, France, the Soviet Union, the UK, and the US—becoming
16320-497: The first Airbus aircraft to be discontinued. The final production A300, an A300F freighter, performed its initial flight on 18 April 2007, and was delivered to FedEx Express on 12 July 2007. Airbus has announced a support package to keep A300s flying commercially. Airbus offers the A330-200F freighter as a replacement for the A300 cargo variants. The life of UPS's fleet of 52 A300s, delivered from 2000 to 2006, will be extended to 2035 by
16480-538: The first being the Anglo-French Concorde . Under the terms of the memorandum, the French and British were to each receive a 37.5 per cent work share on the project, while the West Germans would receive a 25 per cent share. Sud Aviation was recognized as the lead contractor for the A300, with Hawker Siddeley being selected as the British partner company. At the time, the news of the announcement had been clouded by
16640-418: The first prototype A300 began. On 28 September 1972, this first prototype was unveiled to the public, it conducted its maiden flight from Toulouse–Blagnac International Airport on 28 October that year. This maiden flight, which was performed a month ahead of schedule, lasted for one hour and 25 minutes; the captain was Max Fischl and the first officer was Bernard Ziegler, son of Henri Ziegler. In 1972, unit cost
16800-566: The first step of what its government saw as the country's right to rule Asia , staged the Mukden incident as a pretext to invade Manchuria and establish the puppet state of Manchukuo . China appealed to the League of Nations to stop the Japanese invasion of Manchuria. Japan withdrew from the League of Nations after being condemned for its incursion into Manchuria. The two nations then fought several battles, in Shanghai , Rehe and Hebei , until
16960-480: The flight testing of the A300B2, Airbus held a series of talks with Korean Air on the topic of developing a longer-range version of the A300, which would become the A300B4. In September 1974, Korean Air placed an order for four A300B4s with options for two further aircraft; this sale was viewed as significant as it was the first non-European international airline to order Airbus aircraft. Airbus had viewed South-East Asia as
17120-843: The former Chinese imperial capital of Peking after instigating the Marco Polo Bridge incident , which culminated in the Japanese campaign to invade all of China. The Soviets quickly signed a non-aggression pact with China to lend materiel support, effectively ending China's prior cooperation with Germany . From September to November, the Japanese attacked Taiyuan , engaged the Kuomintang Army around Xinkou , and fought Communist forces in Pingxingguan . Generalissimo Chiang Kai-shek deployed his best army to defend Shanghai , but after three months of fighting, Shanghai fell. The Japanese continued to push Chinese forces back, capturing
17280-458: The fuselage, Hawker Siddeley would manufacture the wings, while German companies would produce the forward, rear and upper part of the center fuselage sections. Additional work included moving elements of the wings being produced in the Netherlands , and Spain producing the horizontal tail plane. An early design goal for the A300 that Béteille had stressed the importance of was the incorporation of
17440-479: The introduction of ETOPS rules that allowed twin-engine jets to fly long-distance routes that were previously off-limits to them, Airbus was able to further develop the A300 as a medium- to long-range airliner to increased sales; Boeing launched its widebody twinjet, the Boeing 767 , in response. In the 1980s the Boeing 727 was discontinued, as its central engine bay would require a prohibitively expensive redesign to accommodate quieter high-bypass turbofans, and it
17600-512: The invasion of the Ethiopian Empire (also known as Abyssinia ) by the armed forces of the Kingdom of Italy ( Regno d'Italia ), which was launched from Italian Somaliland and Eritrea . The war resulted in the military occupation of Ethiopia and its annexation into the newly created colony of Italian East Africa ( Africa Orientale Italiana , or AOI); in addition it exposed the weakness of
17760-467: The large American aircraft-manufacturers Boeing and McDonnell Douglas . Aviation author John Bowen alleged that various concessions, such as loan guarantees from European governments and compensation payments, were a factor in the decision as well. Although the A300 was originally too large for Eastern's exiting routes, Airbus provided a fixed subsidy for a 57% load factor which decreased for every percent above that figure. The Eastern Air Lines breakthrough
17920-449: The largest cargo aircraft capable of transporting outsize cargo , including strategic airlifters . Twin-jets tend to be more fuel-efficient than trijet (three engine) and quad-jet (four engine) aircraft. As fuel efficiency in airliners is a high priority, many airlines have been increasingly retiring trijet and quad-jet designs in favor of twinjets in the twenty-first century. The trijet designs were phased out first, in particular due to
18080-402: The largest operator being FedEx Express with 68 A300-600F aircraft. The A300B1 was the first variant to take flight. It had a maximum takeoff weight (MTOW) of 132 t (291,000 lb), was 51 m (167 ft) long and was powered by two General Electric CF6-50A engines. Only two prototypes of the variant were built before it was adapted into the A300B2, the first production variant of
18240-726: The latter enabling the strategic bombing of population centres and delivery of the only two nuclear weapons ever used in war. World War II was the deadliest conflict in history, resulting in 70 to 85 million deaths , more than half being civilians. Millions died in genocides , including the Holocaust of European Jews, as well as from massacres, starvation, and disease. Following the Allied powers' victory, Germany , Austria , Japan , and Korea were occupied, and war crimes tribunals were conducted against German and Japanese leaders . The causes of World War II included unresolved tensions in
18400-514: The market at the same time, neither would achieve sales volume needed to make them viable. In 1965, a British government study, known as the Plowden Report, had found British aircraft production costs to be between 10% and 20% higher than American counterparts due to shorter production runs, which was in part due to the fractured European market. To overcome this factor, the report recommended the pursuit of multinational collaborative projects between
18560-410: The more complicated design and maintenance issues of the middle engine mounted on the stabilizer. Early twinjets were not permitted by ETOPS restrictions to fly long-haul trans-oceanic routes, as it was thought that they were unsafe in the event of failure of one engine, so quad-jets were used. Quad-jets also had higher carrying capacity than comparable earlier twinjets. However, later twinjets such as
18720-478: The most visually unique of the variants is the A300-600ST Beluga , an oversized cargo-carrying model operated by Airbus to carry aircraft sections between their manufacturing facilities. The A300 was the basis for, and retained a high level of commonality with, the second airliner produced by Airbus, the smaller Airbus A310. On 23 May 1974, the first A300 to enter service performed the first commercial flight of
18880-497: The permanent members of its security council . The Soviet Union and the United States emerged as rival superpowers , setting the stage for the Cold War . In the wake of European devastation, the influence of its great powers waned, triggering the decolonisation of Africa and Asia . Most countries whose industries had been damaged moved towards economic recovery and expansion . World War II began in Europe on 1 September 1939 with
19040-571: The political European map with the defeat of the Central Powers —including Austria-Hungary , Germany , Bulgaria , and the Ottoman Empire —and the 1917 Bolshevik seizure of power in Russia , which led to the founding of the Soviet Union. Meanwhile, the victorious Allies of World War I , such as France, Belgium, Italy, Romania, and Greece, gained territory, and new nation-states were created out of
19200-583: The port of Tobruk . By late March 1941, Bulgaria and Yugoslavia signed the Tripartite Pact ; however, the Yugoslav government was overthrown two days later by pro-British nationalists. Germany and Italy responded with simultaneous invasions of both Yugoslavia and Greece , commencing on 6 April 1941; both nations were forced to surrender within the month. The airborne invasion of the Greek island of Crete at
19360-434: The project's costs if France was prepared to do the same. Additionally, the managing director of Hawker Siddeley, Sir Arnold Alexander Hall , decided that his company would remain in the project as a favoured sub-contractor, developing and manufacturing the wings for the A300, which would prove to be an important contributor to the performance of subsequent versions. Hawker Siddeley spent £35 million of its own funds, along with
19520-509: The region's leading aircraft manufacturers. European manufacturers were keen to explore prospective programmes; the proposed 260-seat wide-body HBN 100 between Hawker Siddeley, Nord Aviation , and Breguet Aviation being one such example. National governments were also keen to support such efforts amid a belief that American manufacturers could dominate the European Economic Community ; in particular, Germany had ambitions for
19680-693: The remainder of Czechoslovakia and subsequently split it into the German Protectorate of Bohemia and Moravia and a pro-German client state , the Slovak Republic . Hitler also delivered an ultimatum to Lithuania on 20 March 1939, forcing the concession of the Klaipėda Region , formerly the German Memelland . Greatly alarmed and with Hitler making further demands on the Free City of Danzig ,
19840-762: The requirement that an aircraft be able to continue a takeoff if an engine fails after the takeoff decision speed is reached. Thus, with all engines operating, trijets must be able to produce at least 150% of the minimum thrust required to climb and quad-jets 133%. Conversely, since a twinjet will lose half of its total thrust if an engine fails, they are required to produce 200% of the minimum thrust required to climb when both engines are operating. Because of this, twinjets typically have higher thrust-to-weight ratios than aircraft with more engines, and are thus able to accelerate and climb faster. Second World War Asia-Pacific Mediterranean and Middle East Other campaigns Coups World War II or
20000-629: The same eight-abreast cross-section, the A310 is 6.95 m (22.8 ft) shorter than the initial A300 variants, and has a smaller 219 m (2,360 sq ft) wing, down from 260 m (2,800 sq ft). The A310 introduced a two-crew glass cockpit, later adopted for the A300-600 with a common type rating . It was powered by the same GE CF6-80 or Pratt & Whitney JT9D then PW4000 turbofans. It can seat 220 passengers in two classes, or 240 in all-economy, and can fly up to 5,150 nmi (9,540 km; 5,930 mi). It has overwing exits between
20160-464: The shrink reduced the length of the fuselage by 5.62 metres (18.4 ft) and the diameter by 0.8 metres (31 in), reducing the overall weight by 25 tonnes (55,000 lb). For increased flexibility, the cabin floor was raised so that standard LD3 freight containers could be accommodated side-by-side, allowing more cargo to be carried. Refinements made by Hawker Siddeley to the wing's design provided for greater lift and overall performance; this gave
20320-410: The significant territorial, colonial, and financial losses imposed by the Treaty of Versailles . Under the treaty, Germany lost around 13 percent of its home territory and all its overseas possessions , while German annexation of other states was prohibited, reparations were imposed, and limits were placed on the size and capability of the country's armed forces . The German Empire was dissolved in
20480-442: The specifics of what kind of aircraft that potential operators were seeking. According to Airbus, this cultural approach to market research had been crucial to the company's long-term success. On 26 September 1967, the French, West German and British governments signed a Memorandum of Understanding to start the development of the 300-seat Airbus A300. At this point, the A300 was only the second major joint aircraft programme in Europe,
20640-494: The start or prelude to World War II. The exact date of the war's end also is not universally agreed upon. It was generally accepted at the time that the war ended with the armistice of 15 August 1945 ( V-J Day ), rather than with the formal surrender of Japan on 2 September 1945, which officially ended the war in Asia . A peace treaty between Japan and the Allies was signed in 1951. A 1990 treaty regarding Germany's future allowed
20800-575: The strong Maginot Line fortifications on the Franco-German border, Germany directed its attack at the neutral nations of Belgium , the Netherlands , and Luxembourg . The Germans carried out a flanking manoeuvre through the Ardennes region, which was mistakenly perceived by the Allies as an impenetrable natural barrier against armoured vehicles. By successfully implementing new Blitzkrieg tactics,
20960-446: The technical director of what would become the A300 programme, while Henri Ziegler , chief operating office of Sud Aviation, was appointed as the general manager of the organisation and German politician Franz Josef Strauss became the chairman of the supervisory board. Béteille drew up an initial work share plan for the project, under which French firms would produce the aircraft's cockpit, the control systems, and lower-centre portion of
21120-421: The third configuration both engines are within the fuselage, side-by-side, used by most fighters since the 1960s. Later fighters using this configuration include the Su-27 'Flanker', the F-15 Eagle , and the F-22 Raptor . The first twinjet to fly was the German fighter prototype Heinkel He 280 , flying in April 1941 with a pair of nacelled Heinkel HeS 8 axial-flow turbojets. The twinjet configuration
21280-425: The two main front and rear door pairs. In April 1983, the aircraft entered revenue service with Swissair and competed with the Boeing 767–200 , introduced six months before. Its longer range and ETOPS regulations allowed it to be operated on transatlantic flights . Until the last delivery in June 1998, 255 aircraft were produced, as it was succeeded by the larger Airbus A330-200. It has cargo aircraft versions, and
21440-415: The two wars became World War II in 1941. Other proposed starting dates for World War II include the Italian invasion of Abyssinia on 3 October 1935. The British historian Antony Beevor views the beginning of World War II as the Battles of Khalkhin Gol fought between Japan and the forces of Mongolia and the Soviet Union from May to September 1939. Others view the Spanish Civil War as
21600-428: The type, flying from Paris to London, for Air France. Immediately after the launch, sales of the A300 were weak for some years, with most orders going to airlines that had an obligation to favor the domestically made product – notably Air France and Lufthansa, the first two airlines to place orders for the type. Following the appointment of Bernard Lathière as Henri Ziegler's replacement, an aggressive sales approach
21760-488: The typical passenger count up to 281, with capacity for 20 LD3 containers. Two prototypes were built and the variant made its maiden flight on 28 June 1973, became certified on 15 March 1974 and entered service with Air France on 23 May 1974. For the A300B2-200, originally designated as the A300B2K, Krueger flaps were introduced at the leading-edge root, the slat angles were reduced from 20 degrees to 16 degrees, and other lift related changes were made in order to introduce
21920-407: The war were not fulfilled in the peace settlement. From 1922 to 1925, the Fascist movement led by Benito Mussolini seized power in Italy with a nationalist, totalitarian , and class collaborationist agenda that abolished representative democracy, repressed socialist, left-wing, and liberal forces, and pursued an aggressive expansionist foreign policy aimed at making Italy a world power, promising
22080-475: The war. Germany annexed western Poland and occupied central Poland ; the Soviet Union annexed eastern Poland ; small shares of Polish territory were transferred to Lithuania and Slovakia . On 6 October, Hitler made a public peace overture to the United Kingdom and France but said that the future of Poland was to be determined exclusively by Germany and the Soviet Union. The proposal was rejected and Hitler ordered an immediate offensive against France, which
22240-450: The way. On large passenger jets, the cost of the engines makes up a significant proportion of the plane's final cost. Each engine also requires separate service, paperwork, and certificates. Having two larger engines as opposed to three or four smaller engines will typically significantly reduce both the purchase and maintenance costs of a plane. Regulations governing the required thrust levels for transport aircraft are typically based upon
22400-404: The west halted the German advance for several days, but it was outflanked and encircled by the Wehrmacht . Remnants of the Polish army broke through to besieged Warsaw . On 17 September 1939, two days after signing a cease-fire with Japan , the Soviet Union invaded Poland under the supposed pretext that the Polish state had ceased to exist. On 27 September, the Warsaw garrison surrendered to
22560-483: The world order , and soon began a massive rearmament campaign . France, seeking to secure its alliance with Italy, allowed Italy a free hand in Ethiopia , which Italy desired as a colonial possession. The situation was aggravated in early 1935 when the Territory of the Saar Basin was legally reunited with Germany, and Hitler repudiated the Treaty of Versailles, accelerated his rearmament programme, and introduced conscription. The United Kingdom, France and Italy formed
22720-408: Was US$ 4.6 billion (in 1993 dollars, equivalent to $ 8.76 billion in 2023). In December 1968, the French and British partner companies (Sud Aviation and Hawker Siddeley) proposed a revised configuration, the 250-seat Airbus A250. It had been feared that the original 300-seat proposal was too large for the market, thus it had been scaled down to produce the A250. The dimensional changes involved in
22880-554: Was invaded by Germany. The United States started strategic planning to prepare for a full-scale offensive against Germany. At the end of September 1940, the Tripartite Pact formally united Japan, Italy, and Germany as the Axis powers . The Tripartite Pact stipulated that any country—with the exception of the Soviet Union—that attacked any Axis Power would be forced to go to war against all three. The Axis expanded in November 1940 when Hungary , Slovakia , and Romania joined. Romania and Hungary later made major contributions to
23040-459: Was US$ 17.5M. On 5 February 1973, the second prototype performed its maiden flight. The flight test programme, which involved a total of four aircraft, was relatively problem-free, accumulating 1,580 flight hours throughout. In September 1973, as part of promotional efforts for the A300, the new aircraft was taken on a six-week tour around North America and South America , to demonstrate it to airline executives, pilots, and would-be customers. Amongst
23200-448: Was adopted. Indian Airlines was the world's first domestic airline to purchase the A300, ordering three aircraft with three options. However, between December 1975 and May 1977, there were no sales for the type. During this period a number of "whitetail" A300s – completed but unsold aircraft – were completed and stored at Toulouse, and production fell to half an aircraft per month amid calls to pause production completely. During
23360-545: Was certified on 26 April 1979. The A300-600, officially designated as the A300B4-600, was slightly longer than the A300B2 and A300B4 variants and had an increased interior space from using a similar rear fuselage to the Airbus A310 , this allowed it to have two additional rows of seats. It was initially powered by Pratt & Whitney JT9D-7R4H1 engines, but was later fitted with General Electric CF6-80C2 engines, with Pratt & Whitney PW4156 or PW4158 engines being introduced in 1986. Other changes include an improved wing featuring
23520-769: Was derived into the Airbus A310 MRTT military tanker/transport. Commonly referred to as the Airbus Beluga or "Airbus Super Transporter", these five airframes are used by Airbus to ferry parts between the company's disparate manufacturing facilities, thus enabling workshare distribution. They replaced the four Aero Spacelines Super Guppys previously used by Airbus. ICAO code : A3ST As of September 2023, there are 197 A300 family aircraft in commercial service. The five largest operators were FedEx Express (70), UPS Airlines (52), European Air Transport Leipzig (23), Iran Air (11), and Mahan Air (11). Twinjet There are three common configurations of twinjet aircraft. The first, common on large aircraft such as airliners, has
23680-465: Was formally established following an agreement between Aérospatiale (the newly merged Sud Aviation and Nord Aviation ) of France and the antecedents to Deutsche Aerospace of Germany, each receiving a 50 per cent stake in the newly formed company. In 1971, the consortium was joined by a third full partner, the Spanish firm CASA , who received a 4.2 per cent stake, the other two members reducing their stakes to 47.9 per cent each. In 1979, Britain joined
23840-411: Was made for greater cooperation between European nations in the field of aviation technology, and "for the joint development and production of an airbus". The word airbus at this point was a generic aviation term for a larger commercial aircraft, and was considered acceptable in multiple languages, including French . Shortly after the July 1967 meeting, French engineer Roger Béteille was appointed as
24000-403: Was postponed until the spring of 1940 due to bad weather. After the outbreak of war in Poland, Stalin threatened Estonia , Latvia , and Lithuania with military invasion, forcing the three Baltic countries to sign pacts allowing the creation of Soviet military bases in these countries; in October 1939, significant Soviet military contingents were moved there. Finland refused to sign
24160-403: Was received. The first production model, the A300B2, entered service in 1974, followed by the A300B4 one year later. Initially, the success of the consortium was poor, in part due to the economic consequences of the 1973 oil crisis , but by 1979 there were 81 A300 passenger liners in service with 14 airlines, alongside 133 firm orders and 88 options. Ten years after the official launch of the A300,
24320-433: Was recognized as considerably reducing the project's development costs. To attract potential customers in the US market, it was decided that General Electric CF6-50 engines would power the A300 in place of the British RB207; these engines would be produced in co-operation with French firm Snecma . By this time, Rolls-Royce had been concentrating their efforts upon developing their RB211 turbofan engine instead and progress on
24480-404: Was relocated to Toulouse in January 1974. The final assembly line for the A300 was located adjacent to Toulouse Blagnac International Airport . The manufacturing process necessitated transporting each aircraft section being produced by the partner companies scattered across Europe to this one location. The combined use of ferries and roads were used for the assembly of the first A300, however this
24640-657: Was repulsed with heavy Italian casualties; the campaign ended within months with minor territorial changes. To assist Italy and prevent Britain from gaining a foothold, Germany prepared to invade the Balkans, which would threaten Romanian oil fields and strike against British dominance of the Mediterranean. In December 1940, British Empire forces began counter-offensives against Italian forces in Egypt and Italian East Africa . The offensives were successful; by early February 1941, Italy had lost control of eastern Libya, and large numbers of Italian troops had been taken prisoner. The Italian Navy also suffered significant defeats, with
24800-441: Was required to go through the bureaucracy of the League of Nations, which rendered it essentially toothless. The United States, concerned with events in Europe and Asia, passed the Neutrality Act in August of the same year. Hitler defied the Versailles and Locarno Treaties by remilitarising the Rhineland in March 1936, encountering little opposition due to the policy of appeasement . In October 1936, Germany and Italy formed
24960-402: Was shortly followed by an order from Pan Am . From then on, the A300 family sold well, eventually reaching a total of 561 delivered aircraft. In December 1977, Aerocondor Colombia became the first Airbus operator in Latin America , leasing one Airbus A300B4-2C, named Ciudad de Barranquilla . During the late 1970s, Airbus adopted a so-called ' Silk Road ' strategy, targeting airlines in
25120-405: Was smaller, lighter, and more economical than its three-engine American rivals, the McDonnell Douglas DC-10 and the Lockheed L-1011 TriStar . In order to meet Air France's demands for an aircraft larger than 250-seat A300B, it was decided to stretch the fuselage to create a new variant, designated as the A300B2, which would be offered alongside the original 250-seat A300B, henceforth referred to as
25280-554: Was soon supplanted by twinjets for the narrow-body market; Airbus with the A320 , and Boeing with the 757 and updated "classic" variants of the 737 . During that decade only McDonnell Douglas continued development of the trijet design with an update to the DC-10 , the MD-11 , which initially had a range advantage over its closest medium wide-body competitors which were twinjets, the in-production Boeing 767 and Airbus A300/A310. In contrast to McDonnell Douglas sticking with their existing trijet configuration, Airbus (which never produced
25440-590: Was time-consuming and not viewed as ideal by Felix Kracht , Airbus Industrie's production director. Kracht's solution was to have the various A300 sections brought to Toulouse by a fleet of Boeing 377 -derived Aero Spacelines Super Guppy aircraft, by which means none of the manufacturing sites were more than two hours away. Having the sections airlifted in this manner made the A300 the first airliner to use just-in-time manufacturing techniques, and allowed each company to manufacture its sections as fully equipped, ready-to-fly assemblies. In September 1969, construction of
25600-410: Was used for short-range narrow-bodied aircraft such as the McDonnell Douglas DC-9 and Boeing 737 . The Airbus A300 was initially not successful when first produced as a short-range widebody, as airlines operating the A300 on short-haul routes had to reduce frequencies to try and fill the high-capacity aircraft, and lost passengers to airlines operating more frequent narrow-body flights. However, after
