There doesn't seem to be good info in the manuals regarding proper
operation of the fuel transfer system.  How accurately is it modeled?
What are the transfer switch positions at engine start?  My fuel
transfer system never seems to do what I expect it to based on
switch position(s) > thus my questions.
 I normally start my flights by loading the default Cessna and then
shutting down it engine, electrical system, and magneto switch. I
leave the avionics switch in the ON position.  Then I load a B721
livery (usually Eastern AL).
Thank you,
