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, aviation sales rep for U-Fuel, and president of EAA 1114.
According to AirNav, since Dec. 1 2010, the number of FBOs in the U.S. offering 100LL avgas has dropped from 3,537 to 3,515. This reflects the general decline in sales of 100LL avgas nationally, which has decreased by approximately 4% annually in the past decade, the result of heavy pistons moving to turbines, lighter aircraft shifting to more efficient, autogas-burning LSAs, and an overall decline in the number of hours flown by pilots annually.
During this same period of time, the number of FBOs listed as offering autogas has remained constant at 107, while two in central North Carolina, Raleigh East (W17) and Gilliam-McConnell (5NC3), recently added autogas alongside their 100LL pumps. Since information on AirNav is not always up-to-date, your bloggers maintain a separate list of airports selling autogas at FLYUNLEADED.com Please send us your comments if you have information on autogas sources at airports not found on this list, or if we need to make a correction to the information now on this list.
