I'm helping a friend with his RV-12 Annual Condition Inspection. The Transponder will need re-certification when we are finished. The plane has dual Dynon HDX and Angle of Attack. Pitot, Static and AOA all connect to the ADHRS behind the baggage bulkhead. My question… when performing the pitot / static leakage test, does the AOA need to be blocked off? Would there be a significant leak if the AOA was left open?
