Two new-generation engine options (the Engine Alliance GP7200 and Rolls-Royce Trent 900), combined with an advanced wing and landing gear design, make the A380 significantly quieter than today's largest airliner – enabling this very large aircraft to meet strict local regulations at airports around the world.
With a new wing design and composite materials accounting for 25 per cent of its structural weight, the A380 is the most efficient aircraft all around. By producing only about 75 grams of CO2 per passenger kilometre, the A380 is helping the aviation industry's commitment to minimise greenhouse gas emissions.
A380 reliability and maintainability is further increased with modern technology, including an enhanced onboard central maintenance system and variable frequency generators – which simplify the large aircraft’s electrical generation network. Hydraulic power is provided by two fully independent systems with an operating pressure of 5,000 psi., instead of the conventional 3,000 psi. This capacity for higher pressure results in smaller and lighter hydraulic system equipment, as well as less hydraulic fluid on board, proving how Airbus innovations continue to deliver efficiency in every area of aircraft design and manufacture.
