Williams International recently completed a successful flight test of its FJ44-4 engine using 100 percent sustainable aviation fuel (SAF) on their flying testbed aircraft. The flight was conducted from the Williams International flight operations center in Pontiac, Michigan, and flew to points in northern Michigan with a total of 3.5 hours of flight time at a cruising altitude of FL450. This flight test follows extensive material compatibility and endurance testing that validated engine performance and durability using 100 percent SAF.
Williams Completes Flight Test Burning 100 Percent Sustainable Fuel
Key Takeaways:
- Williams International successfully completed a 3.5-hour flight test of its FJ44-4 engine using 100 percent Sustainable Aviation Fuel (SAF), confirming flawless performance after extensive prior testing.
- This achievement is a key step in Williams' "Blue Planet Initiative" and the broader aviation industry's goal to decarbonize, demonstrating that current engines can operate entirely on pure SAF.
- Despite the engine's proven compatibility, Williams International emphasized the critical need to accelerate the production of SAF to make it more widely available and affordable to truly achieve carbon-neutral aviation.
