Diesel said:our old company the boss would run avgas through the engines to clean the blades off of the pt-6. personally i thought this was more of an old wives tale than anything else.
I have run avgas through king air's when i've been in a jam. Landed at a place that said they had Jet A. They just didn't tell me which day they would have jet A.
In the king air if I remember correctly the boost pumps have to be operational to run avgas. If they aren't you were limited to 18,000 Feet.
It's been a while since I've needed to do it. I was never really comfortable with the idea. They say you get higher ITT's from the avgas but I never saw a difference. Probably because the avgas was "cut" so much by the Jet A.
That is true for some turbine aircraft and not true for others. There will be a section in the flight manual detail what fuels can be burned and with what limitations. It was permissable in some of the airplanes I've flown in the past, but with some restrictions. It's not permissible in the airplane we're flying now. Most jetfuels are blended with a biocide to keep the green things from growing in the tanks.Big Duke Six said:Not sure about "cleaning the system", but they can be run on avgas if the need arises. If I remember right, most engines require a logbook entry if they are run on a certain percentage (or higher) of avgas. It is not the best thing for a jet engine however, so there is a limit on how much avgas can be run.
Check out www.supercub.org There are a bunch of photos there.bugchaser said:Anyone have any pics of airplanes "hydroplaning" or skiing on the water? Having a hard time convincing some people that this is possible. I have seen it done many times. Pretty cool. Of course I would never do something like that.
