Hi,
Quick procedural question: Just prior to the LOI burn the Apollo 14 checklist has a step "OXIDIZER FLOW VALVE INCR-INCR (VERIFY)". During the burn this quickly result in an imbalance between the fuel and oxidizer. It didn't look "normal" to me so I balanced out the fuel and oxid then left the valve in NORM for the rest of the burn.
I don't remember putting this switch to INCR for other LOI burns (or any SPS burns for that matter). What was the reasoning for this?
Thanks
