Each wing tank pump is controlled by its associated pb sw on the FUEL panel. MENU
The MODE SEL pb sw enables the pilot to run the two center tank pumps in automatic or manual mode. MENU This will be explained in detail in the normal and abnormal operation modules.
The X FEED pb sw enables the pilot to connect or isolate the left and right sides of the fuel system. MENU
