Boeing, NASA, United Partner on In-Flight SAF Study

Using a Boeing 737 MAX 10 and a NASA DC-8, the group will monitor and record emission data from the 737 using SAF and traditional jet fuel in flight.

Key Takeaways:

  • Boeing, NASA, and United Airlines are collaborating on in-flight tests to compare the environmental impact of Sustainable Aviation Fuel (SAF) against traditional jet fuel.
  • A Boeing 737 MAX 10 will fly with both fuel types, while a NASA DC-8 airborne laboratory monitors emissions and contrail ice particles to understand their contribution to atmospheric heating.
  • SAFs, made from sustainable sources like cooking oil and agricultural waste, are a promising solution to reduce aviation emissions by up to 85% over their lifecycle, with Boeing committing to SAF-compatible aircraft by 2030.

Airlines and manufacturers across the globe are pouring resources and time into finding a fuel solution that will reduce the impact aviation has on the environment. Boeing, the German Aerospace Center, NASA and United Airlines are continuing the search in a rather interesting way. Using a Boeing 737 MAX 10 painted in a special United eco livery and a NASA DC-8, the group will monitor and record emission data from the 737 using SAF and traditional jet fuel in flight.  

Boeing has used numerous ecoDemonstrator aircraft over the years to improve industry understanding of the impacts aviation has on the environment. Most recently, the Arlington, Va.-based manufacturer has used an Alaska Airlines 737 MAX 9, 777-200ER and 787-10. The 737 MAX 10 which will be used during the air-to-air flights has been painted with a special livery signifying the environmental mission the aircraft will carry out.

Zach’s love for aviation began when he was in elementary school with a flight sim and model planes. This passion for being in the air only intensified throughout high school when he earned his Private Pilot Certificate. He then attended Embry-Riddle Aeronautical University, earning his certificates and ratings to later flight instruct and share his passion for aviation with others. He now resides in the North East living out his dream as an airline pilot.
