Everybody loves a bargain. I know I do. Heck, I may be the cheapest guy you’ll ever meet. But there is a cost associated with saving a dollar or two – and the general aviation crowd may not notice how dear that cost can be until it’s too late.
Tupelo Aviation Unlimited, the FBO at Tupelo Regional Airport (TUP) in Mississippi, has joined the Avfuel network, which means it now offers Avfuel products and services, such as Avfuel Contract Fuel and the rewards program, AVTRIP.
The dust has literally settled in Oshkosh, and there was a good deal of it on the first days of AirVenture 2012 when high temperatures and winds turned the headquarters of U2OSH — Unleaded to Oshkosh — into a blast furnace. A last minute mix-up (EAA had double-booked our space with Beechcraft) forced a move onto Celebration Way, which turned out to be a good location, directly on the main route of travel between the exhibit’s entrance and Phillips66 square. Many members of the Aviation Fuel Club found us and registered for the event, receiving a special decal and T-shirt commemorating the 30th anniversary of the FAA’s approval of the first autogas STC during Oshkosh 1982.
For the first time in more than 30 years, the Illinois Valley Airport (3S4) in Cave Junction, Oregon, has a stable supply of 100LL aviation fuel for piston-engine aircraft.
A coalition of general aviation associations recently called on the FAA to support additional funding for research into a feasible drop-in replacement for leaded aviation fuel, according to a report at NBAA.org. An Aug. 1 letter asks for “adequate funding” of $5.5 million for an avgas program.
The Wednesday, Aug. 8, Wichita Aero Club Luncheon will feature a general aviation industry expert on aviation fuel and the ongoing — and increasingly urgent — need to find a viable replacement for 100LL.
Recently, my wife and I decided to take a road trip to Texas to visit friends and fill up on good Cajun and Tex-Mex food. On our return, I stopped to visit GAMI — General Aviation Modifications, Inc. — in Ada, Oklahoma.
GAMI builds and sells a line of parts designed to improve performance for a variety of aviation applications. It is best known for GAMI injectors. The concept of the GAMI injectors is to even out the variation in air/fuel ratios for all the cylinders of an engine. This, combined with proper instrumentation, will allow the pilot to operate on the lean side to peak. I know many people think that operating on the lean side is operating on the dark side and can harm the engine. However, if done properly, it can be done with little or no problem. There are several advantages to operating on the lean side, but the biggest is that you can decrease your fuel consumption by a very significant amount.
GAMI’s latest project is to design an unleaded fuel that will satisfy the same engines that presently require 100LL. There are presently three approaches to finding a replacement for 100LL.
Lycoming Engines will release Service Instruction SI-1070S in the fall, which will add 20 engines to the list of models approved for use on UL 91 unleaded avgas and bringing the total number approved to 55. With the move, Lycoming officials continue to call for UL100 as a fleetwide solution to replacing 100LL.
