Q

Fuel jettison allows jettison from all fuel tanks through the jettison/refuel manifold to jettison nozzle valves inboard of each aileron. Fuel jettison is initiated by pushing the FUEL JETTISON ARM switch to select ARMED. The TO REMAIN quantity replaces fuel temperature on the EICAS display. If the fuel-to-remain selector is left in AUTO during a fuel jettison, the fuel remaining at the conclusion of the jettison will be…
- reserve fuel entered in the FMC.
- 20,000 pounds.
- the maximum landing weight (MLW) fuel quantity.
- 8,700 pounds in each tank.

A

the maximum landing weight (MLW) fuel quantity.

Q

During jettison, the fuel to remain quantity and associated aircraft gross weight replaces the EICAS display fuel temperature and static air temperature respectively.
- True
- False

A

True

17
Q

Regarding the fuel scavenge system, …
- with main tank pumps ON, a scavenge system operates automatically to transfer any remaining center tank fuel to the main tanks.
- fuel transfer begins when either main tank quantity is less than approximately 35,000 pounds and the center tank pumps are off.
- the system is inhibited if the engine is on suction feed.
- All of the above are correct.

A

All of the above are correct.

18
Q

After fuel jettison is complete, the main tanks will contain no less than…
- 8,700 pounds of fuel.
- maximum landing weight (MLW) fuel.
- maximum zero fuel weight (MZFW) fuel.
- 35,000 pounds of fuel.

A

8,700 pounds of fuel.

19
Q

This display indicates that the fuel temperature is approaching the fuel freeze temperature. The source of the minimum fuel temperature data is…
- the ice detection system.
- the TAT probe.
- the Air Data Reference System (ADRS).
- the fuel freeze temperature entered on the CDU PERF INIT page.

A

the fuel freeze temperature entered on the CDU PERF INIT page.
