FUEL SYSTEM
Pilot’s Operating Manual
FUEL QUANTITY INDICATIONS
The left and right fuel quantity indications on the Copilot’s MFD display the quantity of fuel in each wing
tank. The fuel quantity indications display the actual usable fuel in level flight. The ventral tank fuel
indication receives fuel level information from the associated high level/low level float switch via the
DCU. The indication displays either FULL, EMPTY or a cross-hatch pattern, the cross-hatch pattern
indicating that the fuel level is between full and empty or that electrical power is off. The tanks also
contain a small amount of unusable fuel most of which may be drained together with any water content
from the tanks via the water/fuel drains.
The fuel distribution system is divided into three subsystems:
• Engine feed system
• Wing tank transfer system
• Auxiliary tank transfer system
The engine feed system supplies positive pressure fuel from an electric fuel pump in the rear center
wing section to the engine driven pump in the engine fuel control. The wing tank transfer system allows
fuel balancing between the wing fuel tanks in flight and on the ground. The auxiliary transfer system
distributes fuel from the ventral tank in equal portions to the left and right wing tank systems.
REFUEL/DEFUEL CONTROL and INDICATIONS
During refueling, with airplane batteries ON, fuel quantity is monitored by paging through the pilot’s
CDU to the ENGINE page. This process will also power up other units on the airplane creating a drain
on the airplane batteries.
Drain of the airplane batteries has been reduced on airplanes which have incorporated RAC Service
Bulletin SB 24-3641. Incorporation of this SB allows the display of fuel quantity on the pilot’s CDU
following the selection of the Refuel Control Panel POWER switch to ON. Selecting the airplane
batteries to ON (for these airplanes) is not required.
