Formerly known as the A3XX, Airbus' double-decker passenger jet, the A380, is the largest airliner ever built. Lengthwise, it would nearly stretch from goal line to goal line of a football field while its wing tips would hang well beyond the sidelines. Three full decks will run along the entire length of the plane. Upper and main decks will serve as passenger areas, and will be connected by a grand staircase near the front of the plane and by another smaller staircase at the back.
Although the lower deck will be reserved primarily for cargo, it could be outfitted for special passenger uses such as sleeper cabins, business centers or even child care service. In a one-class configuration, the A380 could accommodate as many as 865 passengers. The more likely three-class configuration will still offer an unprecedented 555 passenger seats. Either way, the A380 would offer 30% - 50% more seating than its direct competition, the Boeing 747-400.
Although the A380 will be able to fly a distance of over 10,000 miles, the plane's usefulness will not be limited to long-haul flights. For instance, many flights within Japan are among the highest in passenger capacity and would be well suited for A380 service, despite their short distances. Whatever the flight distance, a new breed of engines will be required to lift the plane's 1.2 million pounds into the air. Rolls Royce and GE/Pratt & Whitney are both working on engines to provide thrust that will max out at 75,000 pounds. By comparison, the first American jet airliner in service, the Boeing 707, was powered by only 10,000 pounds of thrust.
As amazing as it will be for this behemoth to take off into the air, the A380 faces significant challenges on the ground as well. To integrate into existing airports, the A380 must fit the standard airport-docking plan. The plane's nearly 262-foot wingspan meets this requirement by about 18 inches. Its outer-most engines, however, would hang just beyond the standard 150-foot runway width, requiring upgrades at many airports. The plane's weight will be distributed to 20 landing gear wheels, actually producing less weight per wheel than the 747. The cockpit location, between the main and upper decks, is designed to give pilots a vantage point on the runway similar to that of current airliners.
Due to recent technological advances, Airbus claims the A380 will be a more efficient plane than its rival, the 747. Airbus states the A380 will use 20% less fuel and will fly quieter, cheaper and more environmentally friendly than the 747. Airlines seem to be impressed. So far, ten carriers have declared their interest in the plane, placing options to order a total of 66 planes. The first A380 entered commercial service as early as October of 2005. Airbus A380 History

The 555 seat, double deck Airbus A380 is the most ambitious civil aircraft program yet. When it entered service in March 2006, the A380 was the world's largest airliner, easily eclipsing Boeing's 747. Airbus first began studies on a very large 500 seat airliner in the early 1990s. The European manufacturer saw developing a competitor and successor to the Boeing 747 as a strategic play to end Boeing's dominance of the very large airliner market and round out Airbus' product line-up. Airbus began engineering development work on such an aircraft, then designated the A3XX, in June 1994. Airbus studied numerous design configurations for the A3XX and gave serious consideration to a single deck aircraft which would have seated 12 abreast and twin vertical tails. However Airbus settled upon a twin deck configuration, largely because of the significantly lighter structure required. Key design aims include the ability to use existing airport infrastructure with little modifications to the airports, and direct operating costs per seat 15-20% less than those for the 747-400. With 49% more floor space and only 35% more seating than the previous largest aircraft, Airbus is ensuring wider seats and aisles for more passenger comfort. Using the most advanced technologies, the A380 is also designed to have 10-15% more range, lower fuel burn and emissions, and less noise.
The A380 would feature an advanced version of the Airbus common two crew cockpit, with pull-out keyboards for the pilots, extensive use of composite materials such as GLARE, and four 320 to 347kN (72,000 to 78,000lb) class RollsRoyce Trent 900 or Engine Alliance (General Electric/Pratt & Whitney) GP-7200 turbofans now under development. Several A380 models are planned: the basic aircraft is the 555 seat A380-800 and high gross weight A380-800, with the longer range A380-800R planned. The A380-800F freighter will be able to carry a 150 tonne payload and is due to enter service in 2008. Future models will include the shortened, 480 seat A380-700, and the stretched, 656 seat, A380-900. (The -700, -800, and -900 designations were chosen to reflect that the A380 will enter service as a "fully developed aircraft" and that the basic models will not be soon replaced by more improved variants).
With orders and options from world-renowned customers (Air France, Emirates (the first customer), Federal Express (the cargo model launch customer), International Lease Finance Corporation, Lufthansa, Qantas, Qatar Airways, Singapore Airlines, Virgin Atlantic and Kingfisher), the Airbus A380 was officially launched on December 19, 2000, and production started on January 23, 2002. More airlines have placed orders since. The out of sequence A380 designation was chosen as the "8" represents the twin decks. The entry into commercial service, with Singapore Airlines, was done in March 2006.
A380 final assembly will take place in Toulouse, France, with interior fitment in Hamburg, Germany. Major A380 assemblies will be transported to Toulouse by ship, barge and road.
