While cruising around at appx. 4-5k I noticed my airspeed indicator was reading low. I assumed it was icing and after a bit I descended. At this point I began recording the video below. The ASI then fell to zero but soon rebounded back to life.
You'll see me in the video looking for something to push, pull, or twist to get some heat into the pitot. I now know that it's one of the circuit breakers but as can be seen in the video the appropriate CB is pushed in - hence this (possible) bug report.
I don't recall damaging the wing during the flight and I don't think anybody hit me. I'll do some further tests.
