7.5.8 Fuel Valves
CROSSFEED VALVE
The left and right sides of the fuel system are connected by a crossfeed valve, which
operates automatically to maintain fuel balance between the wings within 50 pounds.
The crossfeed valve requires electrical power to operate and is normally controlled by
the ACS, but can be overridden by initiating manual fuel crossfeed using the fuel
synoptic. A loss of electrical power will cause the crossfeed valve to close.
Commanded crossfeed valve position is displayed on the fuel synoptic. Should the
crossfeed valve fail or not reach its commanded position, a XFEED VLV FAIL
advisory message appears and fuel crossfeed may not be available.
FUEL SHUTOFF VALVES
An electric fuel shutoff valve for each engine is located in the wing root downstream
of the ejector boost pumps and electric fuel pumps. The valves open and close
automatically during normal engine start and shutdown sequence. They also close
when the associated FIRE-ARMED button is pressed. With a loss of electrical power
a fuel shutoff valve will not operate, a L (R) FUEL SOV FAIL advisory message
appears and the fuel shutoff valve will remain in its last commanded position.
7.5.9 Fuel Heat
A fuel/oil heat exchanger in each engine keeps fuel within normal operating
temperature limits.
