Boeing 757 Fuel Pumps

 WELCOME ADVANCE FLYING ACADEMY 

BOEING 757 PILOT TRAINING COURSE STEP BY STEP 


Fuel Pumps
Each fuel tank contains two AC–powered fuel pumps. A single pump can supply 
sufficient fuel to operate one engine under all conditions.
The two center tank fuel pumps have greater output pressure than the left and right main tank fuel pumps. When all six pumps are operating, the center tank pumps override the left and right main tank pumps so that center tank fuel is used before left or right main tank fuel.
If any pump has low output pressure, the appropriate switch PRESS light 
illuminates and the pump pressure EICAS message is displayed. If the left or right 
main tank pump switches are OFF, the low pressure lights are illuminated and 
EICAS messages for the pumps are displayed. When the center pump switches are OFF, the low pressure lights and EICAS messages for the center pumps are inhibited.
To reduce electrical loads, the center tank pumps are inhibited when the associated 
N3 is less than 50% RPM. Thus both center tank pumps are inhibited when the engines are shutdown. As an engine is started and N3 RPM increases above 50%, 
the inhibit is removed for the associated center tank pump.
To reduce electrical loads, the center tank pumps are inhibited when the associated 
N2 is less than 50% RPM. Thus both center tank pumps are inhibited when the engines are shutdown. As an engine is started and N2 RPM increases above 50%, 
the inhibit is removed for the associated center tank pump.
The EICAS caution messages, L or R FUEL SYS PRESS, displays when all fuel 
pumps have low output pressure or all fuel pumps on one side have low output 
pressure and the crossfeed switches are off.
The fuel pump low pressure messages are inhibited by the corresponding L or R 
FUEL SYS PRESS messages.
During normal operation, the EICAS advisory messages CTR L FUEL PUMP and CTR R FUEL PUMP display to indicate depletion of center tank fuel.
With either messages displayed, a small amount of center tank fuel maybe 
indicated. A scavenge system will operate automatically to transfer any remaining 
center tank fuel to the left main tank. Fuel scavenge begins when the left main tank 
is approximately half empty.
The left main tank contains a DC–powered fuel pump. It has no controls or 
indicators. The DC pump operates automatically to provide fuel to the APU when AC power is not available and the APU selector is ON.
