Gulfstream G650 Flies on 100% Sustainable Aviation Fuel

Gulfstream late last week became the first business jet manufacturer to fly one of its aircraft on 100 percent sustainable aviation fuel (SAF). Friday’s milestone demonstration flight from the airframer’s Savannah headquarters using an unmodified G650 was conducted in conjunction with Rolls-Royce, which supplies the ultra-long-range twinjet’s BR725 engines.

During the approximately 2.5-hour flight, those engines consumed SAF consisting of a blend of fuels supplied by World Fuel in Paramount, California, and Virent in Wisconsin. In the case of the former, the fuel was derived from waste fats and plant oils using the hydroprocessed esters and fatty acids (HEFA) process, while the latter was synthesized from plant-based sugars using the synthesized aromatic kerosine (SAK) production pathway.
