Rolls-Royce and Gulfstream Demonstrate 100% SAF Flight Operations
The first test flight of an ultralong-range business jet powered by 100% Sustainable Aviation Fuel (SAF) was achieved using a Rolls-Royce BR725-powered Gulfstream G650 twin-jet over Gulfstream’s headquarters in Savannah, Georgia. At present, SAF is only certified for blends of up to 50% with conventional jet fuel and can be used on all current Rolls-Royce engines.
