1. The wing fuel transfer valves are:
·
Manually controlled and open when the MODE SEL
push button is selected to MAN.
·
Are electrically held closed.
·
Open automatically at the start of refueling.
·
Automatically close if a low level is sensed in
either main wing tank, they automatically close at the next fueling.
2. Why do the center tank pumps stop
automatically when then slats are extended for takeoff?
·
To keep the center of gravity as low as
possible.
·
Dumping takeoff, the center tank fuel is pumped
to the rear to trim aircraft
·
To ensure that the engines are fed from the wing tanks for takeoff
(feeding segregation)
·
During takeoff, the center tank fuel is gravity
fed only.
3. What precaution should you observe when
gravity feeding fuel?
·
Operate the aircraft below 15,000 feet.
·
Use center tank first.
·
Open the crossfeed when above FL250
·
No precautions are necessary.
4. Refueling time at normal pump pressure is
_____ minutes for the wing tanks and _____ minutes for all tanks.
·
15 & 25.
·
17 & 20.
·
15 & 20.
·
25 & 35.
5. With fuel in the center tank the CTR TK
MODE SEL push button selected to AUTO and CTR TK PUMP push buttons ON (lights
out), which of the following conditions cause the center tank fuel pumps to
stop?
·
Extension of the slats (after completion of the short test cycle).
·
Anytime the slats are extended or an overfill
condition is detected in either wing inner cell
·
For a short test period after the first Engine
Master Switch is selected "ON" when the slats are extended.
6. 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:
·
Will operate for a short period after the first
engine MASTER switch is selected ON and while slats are retracted.
·
They will continue to run until the center tank
is empty or slats are extended.
·
Both are correct.
7. After engine start, center tank fuel pumps
run for ______ minutes regardless of slat position.
·
1 minute.
·
2 minutes.
·
3 minutes.
·
5 minutes.
8. After engine shutdown, what are your
actions to close the fuel transfer valves?
·
You have to switch the inner tank pumps off.
·
You have to call maintenance to close the
valves.
·
No action is required. The valves will close automatically during the
next refuelling.
9. Fuel can be transferred from tank to tank:
·
Only on the ground.
·
In flight if the fuel X FEED push button is
selected OPEN.
·
In flight if the fuel X FEED push button is
selected OPEN and center tank MODE SEL push button is selected to MAN.
·
Fuel can never be transferred.
10. Refueling is possible if the aircraft
batteries are the only source of power.
·
True
·
False
11. With the center tank pump mode SEL switch
in AUTO; the center tank pumps:
·
Run for two minutes after both engines are
running.
·
Will not restart untill slats are retracted in
flight.
·
Continue to run until five minutes after the
center tank is empty.
·
All the above.
12. Fuel transfer from the outer compartment to
the inner compartment of the wing tanks occurs when the inner compartment
quantity decreases to:
·
250 kilograms
·
450 kilograms
·
750 kilograms
·
5000 kilograms
13. What indication will you see on the
overhead fuel panel if the center tank has more than 250 kilograms of fuel and
the left or right wing tank have less than 5,000 kilograms.
·
Auto feed fault.
·
Fuel imbalance.
·
Mode select fault.
·
Fuel - Auto feed fault.
14. The Fuel Used indication on ECAM is reset:
·
Manually by the pilot.
·
Automatically at engine start on the ground.
·
Automatically at electric power up of the
aircraft.
15. The fuel quantity indication on ECAM for
the outer cell is boxed amber if:
·
One transfer valve fails to open.
·
Outer cell fuel temperature is high.
·
Both transfer valves fail to open when inner cell is at low level.
16. An amber line appears across the last two
digits of the ECAM FOB indication when:
·
Fuel quantity is unreliable.
·
The center tank pumps are switched off.
·
The center tank pumps have failed.
17. The fuel crossfeed valve is controlled by 2
motors.
·
True
·
False
18. Which of the following would cause the
fault light to illuminate on the MODE SEL push button?
·
Fuel is being burned out of sequence.
·
Crossfeed push button is ON.
·
Center tank pumps do not stop after slat
extension.
·
Center tank pumps do not stop 5 min after center
tank low level reached.
19. The message CTR TK FEEDG appears in the
MEMO. What does this mean?
·
The center tank fuel mode selector is OFF.
·
The center tank pumps are OFF.
·
At least one center tank pump is energized.
·
A reminder to switch the center tank pumps OFF.
20. From which tanks will fuel gravity feed?
·
Outer cell of the wing tanks, inner cell of the
wing tanks, and/or center tank.
·
Inner cell of the wing tanks, and center tank.
·
Outer cell of the wing tanks, and inner cell of the wing tanks.
·
The center tank only.
21. Center tank pumps do not stop 5 min after
center tank low level reached.
·
Yes, only on the refueling panel.
·
It is not possible to determine their position
·
Only on the ECAM Fuel page.

·
The fuel quality is not good and should be

·
Not all the fuel aboard is useable.
24. The APU fuel system:
·
Uses its own dedicated DC powered fuel pump.
·
Obtains fuel from either center tank pump.

or if needed, the APU fuel pump.
·
Obtains fuel from the left fuel manifold via the
right side fuel pumps.
25. The message OUTER TK FUEL XFRD appears in
the MEMO. What does this mean?
·
It is a reminder to show that a transfer valve is open.
·
Fuel is transferring from the center tank to the
inner tank.
·
It is a reminder to open the outer tank transfer
valve.
·
Fuel is transferring from the inner tank to the
outer tank.
26. How has the fuel been transferred from the
outer to the inner tanks?
·
By setting the MODE SEL pushbutton to MAN.
·
The transfer valve has been opened automatically
by the low lever sensor in the center tanks
·
By setting the MODE SEL PB to AUTO
·
The transfer valve has been opened automatically by the low level
sensor in the inner tank.
