The Bell 505 has become the first single-engine helicopter to fly with 100 percent sustainable aviation fuel (SAF). Bell collaborated with Safran Helicopter Engines, Neste, GKN Aerospace, and Virent to achieve this milestone. “Showcasing a single-engine aircraft’s flight capabilities with 100 percent SAF signals Bell’s commitment to alternative fuel usage and builds on its sustainability practices in its flight operations,” said Bell commercial business executive v-p Michael Thacker.

Safran Helicopter Engines' Arrius 2R powers the Bell 505. “Our engines are certified to operate on up to 50 percent SAF and our objective is to certify in the coming years the use of 100 percent SAF, which can potentially result in carbon lifecycle emissions reductions of up to 80 percent,” said Safran Helicopter Engines executive v-p of programs Valentin Safir.
