In notes for 1.27
Only issue I saw was that the fuel transfer pump was set to the AV Master switch and not the transfer fuel switch.
The valve has 3 positions Norm(left only), Emergency (Right only), and OFF.
The Fuel valve in normal should feed from left wing ONLY, and Emergency feeds from Right only, Incase the pump fails.
I was still able to switch for the Right tank using the Emergency valve select once I saw the pump didn’t switch correctly.
