Not the slightest clue what "IMC" means.

Many IR pilots know what it means, but some don't.

I should have said VMC, though; that is, a great deal of IFR flight actually
takes place in VMC, which means that many IR pilots (at least private pilots)
don't have much experience with situations in which they truly must fly by
instruments. They have just enough to get the rating, and that's it.
