WASHINGTON, D.C. – As part of its ongoing efforts to develop an unleaded fuel for general aviation airplanes, the FAA has selected two unleaded fuels for further testing. [Read more…]
I’m submitting this blog on Feb. 2, 2016, Groundhog Day. I think it is the appropriate date choice for my latest GAFuels topic.
It is the kind of day the FAA should get out its plan for the Piston Aviation Fuels Initiative (PAFI), dust it off and see if there is a ray of hope of finding the 100 octane unleaded fuel holy grail.
Or perhaps they see no light at the end of the tunnel and shelve the project into the dustbin of bureaucracy, hoping nobody notices. [Read more…]
The FAA has released some details and photos as the first phase of testing draws to a close of four fuels designed to be a replacement for 100LL.
According to a report at AOPA.org, test rigs have been heated and cooled to extreme temperatures, fuel samples have been run through specially designed rigs replicating aircraft fuel systems on a bench, and ignition temperatures have been carefully measured, to name just a few of the tests designed to winnow down the candidate fuels that will be put through the second, and final, phase of testing that will begin in 2016.
That phase, which will include real-world testing in a variety of aircraft, is scheduled to conclude in 2018.
One year after four fuels were selected for testing as potential replacements for leaded avgas, progress remains steady, according to a report at AOPA.org, which notes that the first phase of testing should be completed later this year. Testing now is concentrated on material compatibility and rig testing, with the second phase of testing — in engines and aircraft — slated to begin in early 2016, according to the report.
“The FAA has said it hopes to have an unleaded replacement for avgas certified by 2018, and the program is on target to reach that goal,” the report concludes.
