And if you take it one step further, since the aircraft isn't being flown
IFR, the airspeed indicator can be a little lightweight plumb bob on the end
of a string held out into the slipstream with a 3x5 recipe card behind it
calibrated in furlongs per fortnight.

Altimeter? Balloon with a calibrated piece of paper behind it. THe bigger
the balloon, the higher you are.

Install an altimiter and and airspeed indicator, put a 3" N number on
it and register it as an airplane. You don't need an inspection.

I have it on good authority that there's a carpet and a broom out
there with registrations. I don't know if anyone's gotten an
airworthyness certificate for one yet. Remember - an airplane doesn't
have to be able to fly to get a cert.
