CFI "soaked air filter, leave on the carb heat." A minute later we had
cleared the shower and went back to normal ops. It's the only time I've had
any engine trouble and it sure gets your attention.


Anytime the engine hiccups while airborne will raise that pucker
factor :-))

Another thing to be aware of when flying in heavy rain is to put your
pitot tube heat on. Only so much room to ingest fluids and drain it
out and this happened to me while I was IMC. My airspeed was
dropping, yet everything indication wise with AI, RPMs, VSI all
checked out straight and level. It was 58 degrees so icing wasn't a
factor.

My instructor told me to put on pitot heat and sure enough after a few
minutes, the airspeed came up to normal indications. He had that
happen to him so he recognized the problem waaaay sooner then me at
that time.

Sooo, anytime I am in precip in IMC, pitot heat goes on and stays on.

Failure to use pitot heat caused the recent B-2 crash in Guam and it was
all about accumulated moisture, not temperature or rain.
