Pratt & Whitney Canada and Gulfstream Mark Historic Transatlantic Flight with 100% Sustainable Aviation Fuel (SAF)

Pratt & Whitney Canada and Gulfstream Aerospace have achieved a significant milestone in sustainable aviation by successfully completing the world’s first transatlantic flight powered entirely by sustainable aviation fuel (SAF). The groundbreaking journey took place between Savannah and Farnborough, showcasing the potential for reducing carbon emissions in aviation.

The flight utilized a Gulfstream G600 business jet featuring two Pratt & Whitney Canada PW815GA engines, capable of running on up to 50% SAF-blended fuel. This achievement underscores the feasibility and environmental benefits of adopting 100% SAF for future flights, potentially cutting carbon emissions by up to 70% compared to traditional jet fuel sources.

The historic flight, which occurred on November 19, 2023, spanned approximately eight hours and relied solely on 100% Hydro-processed Esters and Fatty Acids (HEFA) fuel. This specially formulated fuel, produced by World Energy and distributed by World Fuel Services, adheres to the ASTM D7566 specification for synthetic jet fuel.

This landmark accomplishment was part of a broader collaborative effort between Pratt & Whitney Canada and Gulfstream, centered on advancing alternative material solutions for the PW815GA engines that power the G600 and G500 business jets. These technology insertion programs aim to bolster engine performance, efficiency, and sustainability.

Pratt & Whitney Canada’s extensive experience in SAF compatibility and certification, spanning over a decade, played a pivotal role in making this milestone flight possible. Anthony Rossi, the company’s vice president of marketing, emphasized the importance of this achievement, stating, “With this transatlantic flight, we are effectively demonstrating both engine and aircraft functionality in a fully operational setting to support future specifications for 100% SAF. This will be crucial in realizing a more sustainable aviation future with net-zero CO2 emissions in the decades ahead.”
