Equiping for IFR
I recently read somewhere that a heated pitot tube is required for IFR flight. Then I read an EAA write up on equipment required for IFR which makes no mention of a heated pitot tube. Who's right?

It's not a legal requirement, but it is a very good idea.

Different places, different rules. Canada requires two different types of nav receivers. Here in the US, there is a huge difference between the legal minimum and what mosts pilots feel is needed to operate at a reasonable level of safety.

In the US 91.205 spells out the equipment requirements for all phases of flight: VFR, Night, and IFR. And for those playing at home your OPLIMS will state the entire paragraph applies when equipping for IFR. And as previously stated a heated pitot is not a 91.205 requirement.

Several of the glass EFIS displays use attitude solutions that are pitot dependent. Several modes of most auto pilots are significantly impaired if you loose accurate pitot pressure. As mentioned previously, a heated pitot is a very good idea. Even if you don't plan on flight in IMC, one can find clear air that will produce ice.

The other side of that argument is that on most systems the pitot only provides air speed. Most will have ground speed with their GPS. A pitot can easily be done without.

How does clear air produce ice?

Clear air does not. BUT I would never consider IFR without a working heated pitot tube.
I had one "where the **** did this half inch of ice come from" experience on a severe clear VFR on top day on my descent through the layer. I could not have hit the on switch for pitot heat fast enough. This is the same reason I back fitted a vacuum release check valve in the fuel tank vent lines.
Just put it in.

I agree you should (and I do) have a heated pitot, but there are plenty of valid reasons why, ice in clear weather is not one of them.
