The situation seems to be, for part 91 ops, that if it is forecast,
that is if there is an AIRMET for icing (AIRMET ZULU), then it's not
legal to fly in it without approved deice equipment.

But according to the FAA's definition of "known icing conditions" in the
current AIM (which I quoted and linked to a few messages ago in this
thread), a forecast of icing definitely does *not* count as "known icing
conditions". And the only ice-related prohibition I'm aware of in the POH of
typical small planes is phrased in terms of known icing conditions (not
forecast icing conditions).
