Agree with that. If it is below 40 F, and there is moisture outside,
ice is the number one thing on my mind. The original poster would be
surprised to find that the part of the OAT that is the ice detector is
the outside part, since that is where ice just happens to form first
and very visibly and is the "early warning system". That is the part I
am "scanning" like crazy. Not likely to be surprised or need a gadget
to light a light or sound a buzzer when ice starts.
