King Air drains backup fuel tanks first

[dajackman2 2]

I'm thinking i'm doing something wrong.  I can't get the B200 to use fuel from the primary fuel tanks first.  Always seems to use up the backup tanks then takes fuel from the primary.  Anyone have an idea what i'm doing wrong?  Thanks.

Taken directly from B200 Technical manual

 

"AUXILIARY FUEL TRANSFER

SYSTEM

When auxiliary fuel is available, this system

automatically transfers fuel from the auxiliary

tank to the nacelle tank. No pilot action is involved."

 

 

I read it that Aux tanks are used up first with no action involved, maybe some one will correct but that how I see it.

Thats normal, it burns fuel from the AUXILLIARY tanks first, then the main tanks.

Thanks for the clarification.
