________________________________________________
 1. General_______
 The main transfer system controls the flow of fuel from the center (transfer) tank to the two wing tanks. The system uses jet pumps to move the fuel from the center (transfer) tank to the wing tanks. The Fuel Level Sensing Control Unit (FLSCU) (Ref. 28-46-00) automatically controls the system, but the crew can, if necessary, manually control it from the cockpit.
 The Engine/Warning Display (EWD) (Ref. 31-66-00) and the System Display (SD) (which together make the ECAM) give main transfer system information to the crew. If specified failures occur:
 -a warning is given on the EWD

 -the FUEL page shows on the SD.
 When necessary the crew can make a selection on the ECAM control panel (Ref.
 31-56-00) to look at the FUEL page.
