The Airbus A350 XWB (Extra Wide Body) is the world's most modern and efficient long-range airliner, a clean-sheet design that is a notable example of 21st-century aerospace engineering. Built with over 70% advanced materials, including carbon composites, titanium, and aluminum alloys, the A350 offers a level of fuel efficiency and passenger comfort that was high. Its distinctive "raccoon" cockpit windows and graceful, scimitar-like winglets are matched by the powerful and quiet Rolls-Royce Trent XWB engines. From the versatile A350-900 to the high-capacity A350-1000, this family is designed for the world's longest routes while providing a pressurized cabin altitude and humidity levels that leave passengers feeling refreshed after 18-hour journeys.
