Q

Q 16: With fuel in the center tank, the CTR TK MODE SEL push button selected to AUTO and the CTR TK PUMP push buttons ON (lights out), the center tank pumps:
A: Will operate for a short period after the first engine MASTER switch is selected ON and while slats are retracted.
B: They will continue to run until the center tank is empty or slats are extended.
C: Both are correct.

A

C: Both are correct.

17
Q

A: True.
B: False.

A

A: True.

18
Q 
Q 18: After engine start, center tank fuel pumps run for \_\_\_\_\_\_ minutes regardless of slat position. 
A: 1 minute. 
B: 2 minutes. 
C: 3 minutes. 
D: 5 minutes.
A

B: 2 minutes.

19
Q

Q 19: The message OUTER TK FUEL XFRD appears in the MEMO. What does this mean?
A: It is a reminder to show that a transfer valve is open.
B: Fuel is transferring from the center tank to the inner tank.
C: It is a reminder to open the outer tank transfer valve.
D: Fuel is transferring from the inner tank to the outer tank.

A

A: It is a reminder to show that a transfer valve is open.

20
Q

Q 20: The wing fuel transfer valves are:
A: Manually controlled and open when the MODE SEL push button is selected to MAN.
B: Are electrically held closed.
C: Open automatically at the start of refueling.
D: Automatically close if a low level is sensed in either main wing tank, they automatically close at the next fueling.

A

B: Are electrically held closed.

21
Q

Q 21: Why do the center tank pumps stop automatically when then slats are extended for takeoff?
A: To keep the center of gravity as low as possible.
B: Dumping takeoff, the center tank fuel is pumped to the rear to trim aircraft
C: To ensure that the engines are fed from the wing tanks for takeoff (feeding segregation)
D: During takeoff, the center tank fuel is gravity fed only.

A

C: To ensure that the engines are fed from the wing tanks for takeoff (feeding segregation)

22
Q

Q 22: What precaution should you observe when gravity feeding fuel?
A: Operate the aircraft below 15,000 feet.
B: Use center tank first.
C: Open the crossfeed when above FL250
D: No precautions are necessary.

A

A: Operate the aircraft below 15,000 feet. *

*This is wrong. Gravity Feed Ceiling is determined from the QRH Gravity Feed Procedure.

23
Q

A: 15 & 25. 
B: 17 & 20. 
C: 15 & 20. 
D: 25 & 35.
A

B: 17 & 20.

24
Q

Q 24: After engine shutdown, what are your actions to close the fuel transfer valves?

C: No action is required. The valves will close automatically during the next refueling.

A

C: No action is required. The valves will close automatically during the next refueling.

25
Q

Q 25: Fuel can be transferred from tank to tank:
A: Only on the ground.
B: In flight if the fuel X FEED push button is selected OPEN.
C: In flight if the fuel X FEED push button is selected OPEN and center tank MODE SEL push button is selected to MAN.
D: Fuel can never be transferred.

A

A: Only on the ground.

26
Q

C: By setting the MODE SEL PB to AUTO
D: The transfer valve has been opened automatically by the low level sensor in the inner tank.

A

D: The transfer valve has been opened automatically by the low level sensor in the inner tank.

27
Q
