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.
