Pitot Heat

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

It's about the last thing I would spend money on. For that mission you
don't really need a pitot tube.

I'd take the pitot tube, but I'd skip the heat.

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.

I'll vote "very necessary." Once at the Naval Nuclear Power Preparatory
School, in North Chicago, there was ice on my windshield so thick I
broke the tip off my Herter's sheath knife trying to get it off the
windshield of my car. About 1/4" to 3/8" thick. And that was during the
day in VFR conditions.

Freezing rain?

But did that ice first appear during day VFR conditions?

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.

Unfortunately, I don't recall the details. This was back in 1965.
