"Airbus said Saturday it has put off the departure of an A380 prototype from France in order to replace two of the plane's four engines as a "precautionary measure" at Rolls-Royce's request, but did not elaborate on the problems." The Trent 900 engines for the 380 are not extremely high thrust - about 70,000 lbs, considerably less than 777 engines.
