The new Airbus A380 superjumbo is the largest commercial airliner ever built.With 49 percent more floor space than a 747, the A380 is being designed to carry only 35 percent more passengers in a three-class seating arrangement. This would allow airlines to provide "cruise ship facilities" on board, such as shops, sleeper cabins, day care center, business center, and a gymnasium.On the other hand, an all-coach-class configuration could cram more than 800 passengers into an extended version of the plane.
in spite of its more powerful engines, the A380 will make less noise than its closest competitor, the Boeing 747. The noise dampening is thanks to new engine and wing technology, Airbus says. The company says the plane's fuel consumption will be 2.9 liters (0.76 gallon) per passenger per 100 kilometers (60 miles). "The Airbus A380 will generate about half of the noise of a 747-400 [the biggest of the 747s], for example, and is also more fuel efficient than a small car," said David Velupillai, a spokesperson for Airbus in Toulouse. "It is able to do this through a host of new technology—newer, more efficient engines from either Rolls-Royce or Engine Alliance [a joint venture of General Electric and Pratt & Whitney], better aerodynamic design, and the use of newer and lighter materials."
