Canadian Aviation Authority Teflon carburetor coating test

Tom obtained a copy of the Canadian aviation authority's report on Teflon-lined carburetor icing tests; informed his thinking on the vapor-deposition mechanism.

Someone told me that the Canadian aviation authority — and I have since gotten a copy of this report — ran tests to see if putting Teflon on the surface of the carburetor would prevent ice from building up. They were also interested in deicing of airplane wings. If you've ever taken off in the winter at Logan, they have to spray your aircraft with deicing solution. Do you know what that solution is? Usually it's polyethylene glycol. However, I think they may have switched recently to polypropylene glycol. One of them is toxic, and they have to take the planes over to a little part of the area, because they now have a little dam around there so they can collect all the polyethylene glycol — the EPA gets very upset if you just let it get into the ocean. But now I've noticed they've been deicing just back from the gate, which means they've switched to polypropylene glycol, which is a food additive.
