FUEL DISTRIBUTING – NORMAL OPERATION
Booster pumps and fuel SOV are operated by a switch located on the FUEL
control panel. In normal condition the booster pump in each tank provides a
positive pressure fuel supply to the engines and the cross-feed valve is
closed.
The fuel SOV controls the delivery of the fuel to the engines. When the fuel
SOV is open and a positive pressure is detected, the pressure transducer
gives the read-out of the fuel pressure on the MFD.
NOTE
In the event of loss of fuel pressure from one tank due to a booster
pump failure, the cross-feed valve automatically opens allowing one
booster pump to feed both engines without operating limitations.
