What is really needed for fuel flow tests and reports for airworthy certificate and safe flight?
I see the EAA packet for final registration and airworthiness has a form for fuel flow results but it doesn't really say it is required. And is it required that we do a flow test in a climbing, nose up attitude? I've done several tests including on bench, and two on the RV-7A and am seeing 30+ GPH using the Andair Aux boost pump. I've ensured the vent lines are open and working.
I've heard Van's did fuel flow tests and that I should request a copy of theirs. I asked, but they didn't know of such a report due to builder options.
So does everybody jack up their RVs into a climb configuration and test with the boost pump? Is that what's needed to ensure it will work?
