Rolls-Royce has exceeded the planned 60,000lb (300kN) certification thrust of its Trent 500 by 8,000lb. The engine, under development for the Airbus A340/500/600, has been running on a testbed since late May. The first engine is to complete more than 60h of testing this month, when a second test engine should be running. Six development engines are to be involved by the end of the year.
