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.
On Sept. 20, AOPA Online published an article from the staff of the National Air Transportation Association (NATA) titled “Challenges of a dual-fuel solution”. NATA is the country’s largest trade organization focused on companies providing services to the general aviation community. Reflecting the interests of its major constituents, NATA’s activities are concentrated on turbine-powered aircraft used for commercial purposes as opposed to piston-engine aircraft used in sport aviation. While not explicitly stated in the article, the “dual-fuel solution” that NATA opposes is one consisting of the future unleaded 100-octane replacement to 100LL and a lower octane fuel such as Hjelmco’s 91/96UL or 94UL, a new standard for which is soon to be approved by the ASTM.
The article ignores entirely the existence since the 1980s of a dual-fuel solution that not only can dramatically reduce the use of leaded fuel, but also lower significantly the cost to fly and maintain our aircraft. [Read more...]
