Issues around de-ice on a 182

Turbine-powered transport category airplanes are a different kettle of
fish...but even they are prohibited from flying into forecast severe icing.
In my brief experience flying Part 91 corporate jets we took icing very
seriously in spite of having all the goodies...a chunk of ice can put a
turbine out of action.

The regs I cited all say something to the effect of "..except for those
meeting Appendix C of Part 25...", but those regs were written back in the
40s, when supercooled liquid droplets had not yet been discovered. Forty
microns is less than the size of a pencil lead; the many turboprop ADs that
followed the Roselawn accident tell pilots that any precip that runs back on
side windows are far larger and exceed Part 25 certification standards.

No de-icing system allows a pilot to continue flight in icing conditions
when encountered

Really? I had been under the impression that airline systems did allow
continued flight in icing conditions. That's not true, eh? Okay...well,
in
any case, I think that there are pilots out there that don't understand
that
de-ice doesn't mean you can just bomb on through icing conditions as if
they
weren't there.

If not, so much the better. But if so, it might be helpful to dissuade
someone of that idea.
