Design
In September 2007, Airbus rolled out new design advances to a gathering of 100 representatives from existing and potential XWB customers. The A350 XWB will be built on the technologies developed for Airbus A380 and will have a similar cockpit and fly-by-wire systems layout. The A350 XWB will be made out of 53% composites, 19% Al/Al-Li, 14% titanium, 6% steel and 8% miscellaneous. This compares to the Boeing 787 Dreamliner, which consists of 50% composites, 20% aluminium, 15% titanium, 10% steel and 5% other. October 2008 was the Airbus internal goal to freeze the design and Airbus expects 10% lower airframe maintenance cost and 14% lower empty seat weight than competing aircraft.
Airbus says that the new design provides a better cabin atmosphere with 20% humidity level during flight and typical cabin altitude at or below 6,000 ft (1,800 m), pressurisation at 6,000 ft (1,800 m) and flow management system that adapts cabin airflow to passenger load with draught-free air circulation. Airbus is aiming to certify the A350 with 350 min ETOPS capability upon service entry.
