    320,800
  18. B777 Systems Quiz (Question 18 of 32)At least ___ lbs of fuel remains in each main tank after jettison is complete on the 777-300ER.

  19. The 777-300ER, and 777-200ER if equipped, are equipped with a Nitrogen Generation System (NGS). What is the purpose of this system?
    Reduces flammability of the center wing tank fuel during all phases of flight and for a brief period after landing.
  20. 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.
    8,500
  21. 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.
  22. The TO REMAIN quantity can be manually set during fuel jettison by pulling on and rotating the FUEL TO REMAIN selector.
    True
  23. When are the fuel jettison nozzles inhibited from operating?
    On the ground.
  24. Which tanks can fuel be jettison from?
    All fuel tanks.
  25. When the FUEL IN CENTER message is displayed the center tank pumps switches should be selected on.
    True
  26. 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.
  27. 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.
  28. Select the correct indication(s) of a fuel imbalance.




    A) All of the above.
  29. Pushing the FUEL JETTISON ARM switch arms the jettison system. Also, when the FUEL JETTISON ARM switch is selected to ARM the FUEL TO REMAIN is automatically set to _____________
    Max Landing weight.
  30. During fuel jettison, where is the fuel TO REMAIN quantity displayed?
    It is displayed on the fuel synoptic and it replaces the fuel temperature on EICAS.
  31. Where are the indications of fuel quantity and fuel temperature displayed?
    EICAS display.
  32. What does the EICAS message FUEL LOW CENTER indicate?
    One or both center fuel pump switches are ON and center tank fuel is low.
