Two pumps on same side are needed.

One pump on each side is needed.

Correct! Wrong!

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

Between 20 minutes and 25 minutes.

Slightly more than 1 hour.

Between 33 minutes and 35 minutes.

Correct! Wrong!

In normal conditions, the automatic control of CG begins:

When landing gear is up and slats in.

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

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

Correct! Wrong!

Maximum fuel temperature for JET A and JET A1 is:

+59 deg.C

+62 deg.C

+55 deg.C

Correct! Wrong!

In case of loss of both Fuel Control Monitoring Computers:

Automatic transfer is degraded but it is still available.

Fuel transfers must be manual.

Auto-trim is lost.

Correct! Wrong!

In case of Fuel Center Pumps fault:

Center Tank fuel is unavailable.

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.

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!

A fuel imbalance should be corrected:

Using X-FEED valve.

Using differential power settings.

Using the transfer pumps.

Correct! Wrong!

FAULT lights up on both CTR Tank pbs when:

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

At least one CTR pump has failed.

The CTR tank is empty.

Correct! Wrong!

In ELEC EMER CONFIG:

X-FEED valve remains in the last position.

X-FEED valve automatically opens.

X-FEED valve automatically closes.

Correct! Wrong!

Fuel temperature is:

Measured in all tanks and displayed on ECAM.

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

Measured only in some tanks and displayed on ECAM.

Correct! Wrong!

Electrical power requirements for refueling are:

DC from external power or APU.

Battery power is sufficient.

AC from external power or APU.

Correct! Wrong!

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

All statements are correct.

Left pump 2 remains powered.

The X-FEED valve automatically opens.

Correct! Wrong!

The INNER tanks:

Maintain equal fuel quantity by gravity.

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

Are each divided into four cells.

Correct! Wrong!

Refueling can be controlled from:

The flight deck.

The refuel panel beneath the wing.

All statements are correct.

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

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

Check of block fuel automatically inserted in the FMGS.

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

Correct! Wrong!

In normal operation, engines are always fed from:

INNER Tanks.

CTR Tank for takeoff.

OUTER Tanks in case of overfull condition.

Correct! Wrong!

Minimum fuel quantity for takeoff is:

5 200 kg (11 461 lb).

5 600 kg (12 346 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.

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

One is running and one is in stand-by.

Both are running.

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

Correct! Wrong!

Refueling can be accomplished:

Simultaneously from the right and left sides of the aircraft.

From the left side.

From the right side.

Correct! Wrong!

During manual fuel transfer from CTR to INNER Tank:

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

Center tank pumps are auto controlled to prevent overflow.

Crew must turn off Center Tank Pumps to prevent overflow.

Correct! Wrong!

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

30 minutes before the planned destination.

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).

Correct! Wrong!

When a tank fuel temperature is displayed amber:

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

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

FQI is degraded.

Correct! Wrong!

The L an R STBY PUMPS:

Automatically run when X-FEED is open.

Are located outside of the collector cells.

Are located in the collector cells.

Correct! Wrong!
