In many areas the A380 has proven technologies that will become the standard for the next generation of airliners. As one example, the aircraft benefits from a higher proportion of carbon-fibre composite than any previous Airbus aircraft, around 22% compared with 12% for an A340-600 or 9% on a 777. For the first time, this technology has been applied to major components such as the centre-wing box. The information and data management requirements for an aircraft as large as the A380 also have placed demands on system design. These have been met in two ways. The aircraft’s system uses 22 computers of 7 different varieties that share all the functions traditionally handled by individual " black boxes" Data exchange in the system utilizes a high capacity and high speed datalink with data exchange at a rate of 10 million bits per second, 100 times the capacity of a traditional avionics system.
