737-600/700/800/900 TRAINING MANUAL CDS -- ENGINE DISPLAY - FUEL FLOW/FUEL USED INDICATIONS Fuel Flow/Fuel Used
Fuel flow/fuel used shows as a digital indication on the lower center display unit (DU). The digital readout and highlight box are white in color.
Fuel flow normally shows, but if you select FUEL USED on the engine display control panel, fuel used shows. The common display system (CDS) does an integration of fuel flow over time to get fuel used. You select RESET on the engine display control panel to do a reset of fuel used to zero. The reset function operates with the airplane on the ground or in the air.
When you select FUEL USED, the fuel indication shows fuel used for ten seconds after you release the switch. If you hold the switch for longer than thirty seconds, CDS finds that the switch is in a stuck position, and the display changes back to fuel flow.
If fuel flow data from the EECs is not valid, the digital readout is blank.
