Airbus A380 is the world’s largest passenger aircraft, a two-tiered aircraft that operates four four-cylinder Trent 900 jets manufactured by Rolls-Royce, manufactured by the European aircraft manufacturer Airbus, Its first effective flight on 27 April 2005 from the airport of the city of Toulouse, one of the southern cities of France.  The plane made its first commercial flight on 25 October 2007 with Singapore Airlines and the Singapore – Sydney flight route was called during development and before it appeared to light Airbus A3XX, and the aircraft was later dubbed “Super Jumbo” as the largest capacity Rh modern civil passenger. The Airbus A380 is the largest passenger aircraft in the world, but it is shorter than the Airbus A340-600. The aircraft has a model other than the passenger model, the Airbus A380-800F, which is one of the largest existing airliners In the world, its payload surpasses the Russian Antonov A-225 cargo plane.  The Airbus A380-800 provides the aircraft with a capacity of 15,200 kilometers (8,200 nautical miles), which can fly from Hong Kong in China to Boston, USA, with an actual speed of 0.85 Mach (about 900 km / h) The Airbus A380 is the first commercially operated liquefied natural gas jet.
In the summer of 1998, a group of Airbus engineers led by engineer Jean Roeder secretly worked on the development and production of a large-scale commercial aircraft in order to break the dominance and monopoly of the Boeing 747 aircraft, Since 1970,
On December 19, 2000, the new design advisory board approved Airbus to launch a € 8.8 billion program to build the A3XX, which later became A380 with orders for six customers with 55 aircraft. The A380 was later launched as a result of the follow-up of the Airbus, which began with the Airbus A3300 up to the A340. The number eight was chosen because it was of the same size as the aircraft, and also because it was a lucky number in Asian countries where the aircraft was being marketed. The final configuration of the aircraft was discontinued in early 2001 and the first boxing of the first Airbus A380 wing was manufactured on 23 January 2002. The completion of the first aircraft has increased the cost of a single aircraft to 11 billion euros.
At the same time, Boeing studied various Boeing 747-400 models until the Boeing 747-8 construction project was launched in November 2005 (the date of entry into service in 2009). Boeing has chosen to develop a 400-seat, or 500-seat, model for the market, rather than the A380
The new Airbus is sold in two models. The A380-800 is originally designed to carry 555 passengers on three levels, or 853 passengers (538 in the lower main floor and 315 in the upper floor) with one economy class. 
New engines from Rolls-Royce have been used with 30% greater power than the Boeing 747 engines
The Airbus A380 can operate on an industrial jet fuel mixture and components derived from natural gas. On February 1, 2008, a three-hour flight from Airbus Airport in Felton, UK landed at the main Airbus plant in Toulouse, France. One of the four aircraft engines on the trip used a mixture consisting of 60% jet fuel of kerosene and 40% liquefied gas delivered by Shell. Based on the success of the pilot flight, the aircraft does not need any modification to the use of liquefied gas, which was designed to mix with ordinary jet fuel.
“The liquefied gas used is not cleaner in terms of carbon dioxide than conventional jet fuel, but it is environmentally friendly where it does not contain sulfur,” said Sebastien Remy, president of the alternative Airbus program.  
Airbus is scheduled to take another test flight in 2009.
In November 2007, Airbus’ top sales executive and chief executive John Lehigh confirmed the company’s plans to produce a larger model of the A380-800, the A380-900, which would be longer than the A380-800 by 79.4 to 73 meters, or 260 to 240 feet.  This model will accommodate 650 passengers in standard configuration, and about 900 passengers in economy class configuration only. The A380-900 is planned to take off as soon as the A380-800 is delivered to 40 aircraft per year, expected in 2010. Based on this date, the first A380-900 can be delivered in 2015, which means about the same delivery time The A380-800F (charging model). Airlines that have expressed interest in buying the new model including Emirates,  Virgin Atlantic,  Kathy Basfek,  Air France / KLM,  Lufthansa,  King Fisher Air Lines, , in addition to the airline leasing company ILFC.  “The company will make its options open to its demands by identifying the first 10 aircraft as 800 and nine,” Singapore Airlines Chief Executive Chu Chun Singh said in an interview with Airworld magazine in December 2007 when the company received their first A380-800. The rest can be transferred to the new model – 900 “. But that does not seem to be verifiable since their No. 11 plane was sent back to Toulouse as an A380-800.
With the beginning of 2010, Airbus will offer an optional increase in maximum weight for take-off and thus better load / capacity performance. This optional offer is a challenge to the potential Boeing 747-8 model. The increase in the maximum weight of the takeoff is not yet known. Emirates and British Airways will be the first to receive this optional offer
