David:

I've thought about it and my A/I says FAA would probably
accept a heated pitot as a minor mod. The biggest problem is
that the heat requires approximately 8 amps current. With a
bunch of radios and lights, you really need an alternator to
power it all. The $100 pitot can then really get expensive.
Since the coupe is spin proof, my philosophy is that RPM,
vertical speed, and a GPS for ground speed provide an
acceptable airspeed backup. Of course I can't rely on the
VSI until I hook up an alternate static source, but that's a
lot cheaper than the heated pitot.

I have more concern about the roll axis because all my gyro
instruments are vacuum. I had a Precise Flight intake
manifold vacuum on my previous aircraft and am putting that
ahead of a heated pitot on my safety list.
