Q

At least ___ lbs of fuel remains in each main tank after jettison is complete on the 777-300ER.

A

8,500

19
Q

The 777-300ER, and 777-200ER if equipped, are equipped with a Nitrogen Generation System (NGS). What is the purpose of this system?

A

Reduces flammability of the center wing tank fuel during all phases of flight and for a brief period after landing.

20
Q

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.

A

8,500

21
Q

What will cause the expanded fuel indication (left main, center and right main tank quantities) to be displayed on EICAS?

A

One or both crossfeed valves open.

One or more fuel tank quantity indications are inoperative and various fuel system non-normals.

The airplane is on the ground with one or both engines off.

All of the above.

22
Q

The TO REMAIN quantity can be manually set during fuel jettison by pulling on and rotating the FUEL TO REMAIN selector.

A

True

23
Q

When are the fuel jettison nozzles inhibited from operating?

A

On the ground.

24
Q

Which tanks can fuel be jettison from?

A

All fuel tanks.

25
Q

When the FUEL IN CENTER message is displayed the center tank pumps switches should be selected on.

A

True

26
Q

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?

A

The right center tank pump switch PRESS light will stay illuminated until after engine start. The pump pressure EICAS message is also inhibited.

27
Q

How is fuel supplied to the engines with all fuel pumps operating?

A

The center tank pumps override the main tanks pumps so that center fuel is used before main tank fuel.

28
Q

Select the correct indication(s) of a fuel imbalance.

A

The fuel imbalance amber pointer flashes if the fuel balancing is going in the wrong direction.

All of the above.

A solid amber pointer replaces the white pointer if the FUEL IMBALANCE message is displayed.

A solid white pointer is displayed if the expanded fuel indications are displayed, and main tank fuel differs by more 1,000 lb (200 lbs. with a crossfeed valve open).

29
Q

Identify the true statements regarding the Fuel Jettison ARM switch?

A

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
Q

During fuel jettison, where is the fuel TO REMAIN quantity displayed?

A

It is displayed on the fuel synoptic and it replaces the fuel temperature on EICAS.

31
Q

Where are the indications of fuel quantity and fuel temperature displayed?

A

EICAS display.

32
Q

What does the EICAS message FUEL LOW CENTER indicate?

A

One or both center fuel pump switches are ON and center tank fuel is low.

33
Q

With the synoptic shown, how much fuel will be jettisoned once the jettison valves are opened?

Total Fuel 185.0
To Remain 100.0

A

85,000 lbs.

34
Q

In this synoptic showing fuel jettison in progress, how many jettison and jettison/override pumps are operating?

A

4

35
Q

Using this synoptic, how long will it take to jettison fuel down to the selected fuel-to-remain?

A

12 minutes

36
Q

The objective of the Fuel system EICAS message “FUEL DISAGREE” is to check for indications of a fuel leak. Which of the following is an indication of a fuel leak?

A

totalizer fuel quantity and FMC calculated fuel quantity disagree

37
Q

If the crew chief advises you that a fuel spill has just occurred, ____.

A

do not start or stop the APU

38
Q

During preflight on a DFW to London Gatwick flight, you note that the fuel is loaded with 61,500 in each main tank and 11,000 in the center tank. You should ____.

A

check the fuel slip for fuel density to determine whether the mains are full

39
Q
  1. A short time after takeoff, you notice this EICAS advisory. You should ____.

Fuel Low Center

A

turn off the center fuel pumps

40
Q

After turning off the center fuel pumps and continuing the flight, three hours later, you look at the fuel synoptic and note that each wing has 36,000 pounds and there is still 2000 pounds in the center. You should ____ if you are in a 777-200ER..

A

recognize that this is normal and wait for the center fuel to be scavenged

41
Q

About one hour after departure from JFK to NRT, a serious situation causes you to divert to ORD. You have decided to jettison fuel to avoid landing overweight. Upon arming the fuel jettison system, your EICAS fuel display shows the ____.

A

fuel TO REMAIN quantity at maximum landing weight, replacing fuel temperature indication

42
Q

After opening the fuel jettison nozzles, you get very busy performing other duties and forget about monitoring jettison progress. A fault causes the automatic shutoff of the fuel jettison system to fail. What will happen on the 777-200ER?

A

At least 11,500 pounds of fuel will remain in each main tank after jettison is complete

43
Q

You continue and land at ORD with the fuel jettison nozzle switches ON. What will happen?

A

The nozzles should close on landing.
