The Eliminate Aviation Gasoline Lead Emissions (EAGLE) initiative has introduced a new interactive toolkit to help general aviation keep track of the status of the transition to unleaded fuel.
Introduced in June 2025, the toolkit includes information to help keep those who are impacted by the transition — from fuel producers and distributors to airports, FBOs, pilots, aircraft owners, and mechanics — “track the transition and assess its scope, scale, and impact,” according to EAGLE officials.
The new interactive toolkit, available at flyEAGLE.org, offers regularly updated insights into the U.S. piston fleet, fuel infrastructure, airport fuel availability, 100LL production and logistics, sales volumes, per-capita data, and more.
“The toolkit is searchable, sortable, visual — and most importantly — designed to clarify how the transition is unfolding across the national aviation landscape,” officials explained.
What’s available now:
Airport Fuel Availability: U.S. airports offering 100LL, UL94, mogas, or G100UL
Refinery & Distribution Map: Current avgas production and distribution network
Sales Volume & History: State-by-state and national fuel usage back to the 1960s
Piston Aircraft Registry: Ability to search by airframe or engine to assess fleet eligibility
Mechanics & IA Capacity: Data to understand workforce availability for compliance
Per Capita Fuel Usage: Information to identify heavy-use states like Alaska, Montana, and Wyoming
Piston Aviation Fuel Initiative (PAFI) Progress
The site also provides a summary of the FAA’s Piston Aviation Fuels Initiative (PAFI) fleet authorization process and the testing status of the LyondellBasell/VP Racing high-octane unleaded aviation gasoline (UL100E). The data highlights progress across testing areas, including detonation and performance, durability, flight testing, and materials compatibility with components such as O-rings, OEM wing tanks, and paint.
