Preparing for the day when 100LL avgas will be outlawed in America, the FAA has selected two unleaded fuels — one from Swift Fuels and one from Shell — for further testing.
FAA Selects Two Unleaded Fuels for Testing
Key Takeaways:
- The FAA has selected two unleaded fuels from Swift Fuels and Shell for extensive testing as part of the Piston Aviation Fuel Initiative (PAFI), aiming to replace 100LL avgas which is facing an eventual ban.
- These fuels will undergo rigorous flight trials and rig testing through 2018 to gather data necessary for developing an ASTM standard.
- The ultimate goal is to certify these new formulations as drop-in replacements for the majority of piston aircraft engines currently using 100LL, impacting approximately 167,000 GA aircraft.
