it would have helped if the original poster had mentioned the yr/make/model
of the aircraft..
I agree that Bob's first answer was correct... check the certification.. and
go by that..

The 1956(?) Cessna 175 I once owned had pitot heat, but I can't deny that
you are right. I wonder how many questions posed in the newsgroups would
be answered differently if we took into account the totality of GA
history. I know that there are a lot of CAR 3 airplanes still flying in
the GA fleet, but I have a habit of answering questions based on more
recent standards.

FAR 23.1323(d) tells manufacturers that if IFR certification is
requested,
pitot heat is required. Check your AFM to see if the plane is
certificated
for IFR and you have your answer....if it is "yes," the airplane is not
airworthy without it.

How necessary would it be to have a pitot heater if you are flying
year-round VFR day (only) in the Chicago area?


Many small single engine aircraft are IFR capable and airworthy, but
were never built with pitot heat. The early PA 28-140 and Cessna 175
didn't even have a pitot head, let alone heat. Just an end of an
aluminum tube end pointing forward. Still legal per the original
drawings. CAR 3 certification basis, Bob, not Part 23.
