Agree with John, my fuel pump is always on below 1K feet regardless of it being in phase 1 or just another flight. It costs us nothing to run the pump and if it's needed, it's already on.

Good luck Cal, wish you the best! Hope to make it out to Montana next year and experience the beautify it offers pilots.

+1. So many are taught ‘aux pump on for landing and take off’ but in reality the rule should be ‘aux pump on anytime close to the ground’ (e.g., 1000’ or less).

I didn’t quite understand the ‘switch stick hands to activate boost pump’ comment. I’m a bit surprised the A/W inspector would accept such poor ergonomics.

Cal,

Sorry about your first RV-9A, but glad to hear you're building again.

Something else to consider if a tank is run dry or unported. Excerpt from the Airflow Performance Auxiliary Pump document:

Thanks all for the comments. I agree the boost pump should be near the throttle, right hand in my RV-9. Also that boost pump at 1,000 feet or less as a good practice. My boost pump switch was in a row on the left lower panel, just because I copied my prior plane setup. My mistake. I also wasn’t diligent about using it always as I had never run a tank dry. Flying often has lessons in blood. I trained in high wing Cessnas and a “both” fuel selector so never trained well enough for a low wing (I had an rv-12 that had the aux fuel pump on continuously). Every plane has its best practices.
