Key Takeaways:

  • Boeing, NASA, United Airlines, and the German Aerospace Center are conducting in-flight tests to compare emissions from Sustainable Aviation Fuel (SAF) and traditional jet fuel using a Boeing 737 MAX 10 and a NASA DC-8.
  • The 737 MAX will fly with both fuel types, allowing the NASA DC-8 to collect atmospheric data on emissions and contrail ice particles, aiming to understand how fuel designs and engine technologies can reduce atmospheric heating.
  • This initiative seeks to advance Sustainable Aviation Fuel (SAF), which can reduce lifecycle emissions by 85% and is seen as the most promising solution for aviation sustainability, 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.
