Reduces flammability of the center wing tank fuel during all phases of flight and for a brief period after landing.
Using the automatic feature of the fuel jettison system, fuel will be jettisoned until the MLW has been achieved. Manually adjusting the TO REMAIN quantity will never leave you with less than _____ pounds in each main wing tank on the 777-300ER.
What will cause the expanded fuel indication (left main, center and right main tank quantities) to be displayed on EICAS?
A) All of the above.
The TO REMAIN quantity can be manually set during fuel jettison by pulling on and rotating the FUEL TO REMAIN selector.
When are the fuel jettison nozzles inhibited from operating?
On the ground.
Which tanks can fuel be jettison from?
All fuel tanks.
When the FUEL IN CENTER message is displayed the center tank pumps switches should be selected on.
On the ground, what are the indications that a center tank fuel pump operation has been inhibited due to only one electrical power source being available?
The right center tank pump switch PRESS light will stay illuminated until after engine start. The pump pressure EICAS message is also inhibited.
How is fuel supplied to the engines with all fuel pumps operating?
The center tank pumps override the main tanks pumps so that center fuel is used before main tank fuel.
