British Airways (BA) has reduced some frequencies because of durability issues with the Rolls-Royce Trent 1000 engines powering its Boeing 787 aircraft.
The GEnx-1B has extended its lead over the Trent 1000 among Boeing 787 customers in recent years despite Rolls-Royce's best efforts to improve its engine.
Ethiopian Airlines says the situation with its Rolls-Royce Trent 1000s has become one of its biggest challenges, while Gulf Air says it is holding back its growth.
Flying with three engine types, Rolls’ unusually configured testbed is designed for high-altitude evaluation of the Pearl 10X for Dassault’s long-range Falcon.
Taking technologies from demonstrator programs like UltraFan, Rolls-Royce aims to significantly improve the durability of its latest Trent widebody engines.
Aviation executives say the flight proves SAF can safely be dropped-in for jet fuel, while environmental campaigners say Virgin's world-first is greenwashing.
