GAMI G100UL Avgas Flight Trial

摘要

GAMI (General Aviation Modifications Inc.) is well known for its GAMIjector fuel nozzles, several turbonormalizing engine upgrades and, most recently, for developing the first (and so far, the only) high-octane unleaded aviation gasoline. Known as G100UL, it was approved by the FAA in 2022 to operate in all piston, spark-ignition aircraft engines and is currently the only avgas to have an FAA-approved commercial production specification. I have been aware of GAMI's unleaded fuel development program since it began in 2009. With its 2022 FAA approval, I added G100UL to the fuel limitations section of the Airplane Flight Manual for my completed Van's RV-14 ("White Lightning") prior to its FAA inspection and licensing. To my knowledge, as the builder/manufacturer of the aircraft, I became the first to approve operation on an unleaded 100-octane aviation gasoline. And so I made a stop at GAMI's Ada, Oklahoma, headquarters and tanked up with G100UL.
