Refueling can be controlled from:

All statements are correct.

The flight deck.

The refuel panel beneath the wing.

Correct! Wrong!

In ELEC EMER CONFIG:

X-FEED valve automatically closes.

X-FEED valve automatically opens.

X-FEED valve remains in the last position.

Correct! Wrong!

In case of loss of both Fuel Control Monitoring Computers:

Automatic transfer is degraded but it is still available.

Auto-trim is lost.

Fuel transfers must be manual.

Correct! Wrong!

FAULT lights up on both CTR Tank pbs when:

At least one CTR pump has failed.

The automatic CTR to INNER transfer has failed and both inner tank quantities are above 17 000 kg (37 480 lb).

The CTR tank is empty.

Correct! Wrong!

In normal operation, the automatic control of CG will stop:

To destination.

During descent at FL 245 or 35 minutes (75 minutes if trim tank transfer pump has failed)

When below FL 210 and speed less than 280 kts (safety valves).

30 minutes before the planned destination.

Correct! Wrong!

To supply both engines with X - FEED Valve OPEN:

Two pumps on same side are needed.

One pump on each side is needed.

One pump on one side is sufficient.

Correct! Wrong!

When a tank fuel temperature is displayed amber:

FQI is degraded.

FWC 1 or 2 alert flight crew to apply special procedures.

FCMC 1 is no more usable and FCMC 2 is automatically selected.

Correct! Wrong!

In case of Fuel Center Pumps fault:

Center Tank fuel is transferred to the Inner by gravity and is only partly usable.

Center Tank fuel is transferred to the Inner by gravity and totally usable.

Center Tank fuel is unavailable.

Correct! Wrong!

The INNER tanks:

Maintain equal fuel quantity by gravity.

Are each divided into four cells.

Are each divided into two parts, which may be isolated.

Correct! Wrong!

The fuel system is fully automatic. The only actions required before flight are:

Selection and insertion of the proper fuel load, ZFW and ZFWCG in the FMGS.

Check of block fuel automatically inserted in the FMGS.

Selection of the proper fuel load and insertion of GW in the FMGS.

Correct! Wrong!

There are two fuel pumps in each collector cell. They normally are both selected ON and:

Both are running.

One is running and one is in stand-by.

One is running and one is in stand-by depending on which engine has been starting first.

Correct! Wrong!

With tanks nearly empty, time for refueling all the tanks of the aircraft is approximately (depending on the nominal pressure) is:

Between 33 minutes and 35 minutes.

Slightly more than 1 hour.

Between 20 minutes and 25 minutes.

Correct! Wrong!

Electrical power requirements for refueling are:

AC from external power or APU.

DC from external power or APU.

Battery power is sufficient.

Correct! Wrong!

In case of an "ALL ENGINES FLAME OUT" situation:

The X-FEED valve automatically opens.

Left pump 2 remains powered.

All statements are correct.

Correct! Wrong!

Refueling can be accomplished:

From the right side.

Simultaneously from the right and left sides of the aircraft.

From the left side.

Correct! Wrong!

Automatic refueling ensures that:

May take as long as one hour using both refuel panels if all tanks are to be filled.

CTR tank is refueled only if inner tanks are expected to be full.

INNER tanks are filled first, followed by CTR and TRIM tanks.

Correct! Wrong!

The L an R STBY PUMPS:

Are located outside of the collector cells.

Automatically run when X-FEED is open.

Are located in the collector cells.

Correct! Wrong!

Fuel temperature is:

Measured only in some tanks and displayed on ECAM.

Measured in all tanks and displayed on ECAM.

Not available to the crew except in case of excessive temperature.

Correct! Wrong!

A fuel imbalance should be corrected:

Using differential power settings.

Using the transfer pumps.

Using X-FEED valve.

Correct! Wrong!

In normal conditions, the automatic control of CG begins:

Only if there is fuel in the trim tank at takeoff.

When landing gear is up and slats in.

When crossing FL 255 during climb to reach AFT CG target minus 0.5%.

Correct! Wrong!

In normal operation, engines are always fed from:

INNER Tanks.

OUTER Tanks in case of overfull condition.

CTR Tank for takeoff.

Correct! Wrong!

During manual fuel transfer from CTR to INNER Tank:

Crew must turn off Center Tank Pumps to prevent overflow.

Center tank transfer should not be started until inner tanks will hold all the fuel.

Center tank pumps are auto controlled to prevent overflow.

Correct! Wrong!

The Airbus A330 fuel system:

Stores fuel in center tank, wing tanks and the trimmable horizontal stabilizer tank.

Has two inner tanks divided into three parts which are normally interconnected.

Has surge vent tanks in the outer, inner, center and trim tanks.

Correct! Wrong!

Maximum fuel temperature for JET A and JET A1 is:

+55 deg.C

+59 deg.C

+62 deg.C

Correct! Wrong!

Minimum fuel quantity for takeoff is:

5 600 kg (12 346 lb).

5 200 kg (11 461 lb).

4 500 kg (9 921 lb).

Correct! Wrong!

The ECAM alerts that are related to fuel low level in the wing tanks (FUEL WING TK LO LVL, etc.) must not appear for takeoff.
