AOPA: un test comparatif de la 100LL et de la 100 sans plomb sur le même avion bimoteur.

The association has leased a refurbished 1966 Beechcraft Baron with two freshly overhauled, normally aspirated Continental IO-520 engines. It  will operate the aircraft with leaded 100LL avgas fuelling the starboard engine, and 100 octane unleaded supplying the port engine.

The unleaded fuel is G100UL developed by General Aviation Modifications Inc (GAMI) and has received a Supplemental Type Certificate (STC) from the FAA. AOPA says that as other 100-octane unleaded fuels become available it will test those too.
