The GAfuels Blog is written by two private pilots concerned about the future availability of fuels for piston-engine aircraft: Dean Billing, Sisters, Ore., an expert on autogas and ethanol, and Kent Misegades, Cary, N.C., an aerospace engineer and aviation journalist.
One alternative to 100LL avgas, 94 UL, was just approved by ASTM and will be published soon as ASTM D7592-2010. ASTM is now working on 100VLL, a 100 octane fuel containing lower levels of lead than 100LL.
A new workgroup has been established: ASTM WK30832 – Revision of D910 – 07a Standard Specification for Aviation Gasolines. The outline of their work can be seen here in this report.
ASTM is also working on “… an effort to streamline and simplify the logical placement of a new fuel into one of the existing ASTM specifications…”, ASTM WK30824 – Revision of D910 – 07a Standard Specification for Aviation Gasolines.
