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 fuel candidates, from Swift Fuels and Shell, for advanced testing under the Piston Aviation Fuel Initiative (PAFI) as a replacement for 100LL avgas.
- These selected fuels will undergo flight trials and rig testing through 2018 to develop an ASTM standard, enabling them to be a drop-in replacement for current piston aircraft engines.
- This initiative is crucial for general aviation, preparing for the eventual outlawing of 100LL avgas by the EPA, which currently powers approximately 167,000 U.S. GA aircraft.
