The Trent XWB will power the new Airbus A350 XWB. The Trent XWB is the fastest-selling Trent engine ever, with more than 1,100 already sold. At the 2011 Paris Airshow Rolls-Royce also announced that it will be the exclusive engine supplier for the longer range A350-1000 aircraft.

Chris Young, Rolls-Royce, Trent XWB Programme Director, said: "It's a great moment to see the Trent XWB take to the air for the first time. Today's flight is the product of years of work and demonstrates the progress being made on our journey to deliver this world leading technology."

Data recorded during a series of test flights that will accumulate around 175 flight hours and which will run for a seven month period, will validate results from ground testing and demonstrate the engine's in-flight performance. The Trent XWB has already successfully completed more than 1,500 hours of testing, including endurance running, icing and simulated altitude.
