Key Takeaways:

A Gulfstream G650 completed the first ultralong-range business jet flight by an original equipment manufacturer (OEM) fueled entirely by 100 percent Sustainable Aviation Fuel (SAF).
The flight, a collaboration between Gulfstream and Rolls-Royce, advances both companies' sustainability goals and efforts towards decarbonization.
The test demonstrated that current Rolls-Royce BR725 engines can operate on 100 percent SAF as a "drop-in" fuel, paving the way for future certification beyond the current 50 percent blend limit.
