In case of loss of both Fuel Control Monitoring Computers:

Fuel transfers must be manual.

Auto-trim is lost.

Automatic transfer is degraded but it is still available.

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, engines are always fed from:

OUTER Tanks in case of overfull condition.

CTR Tank for takeoff.

INNER Tanks.

Correct! Wrong!

Maximum fuel temperature for JET A and JET A1 is:

+62 deg.C

+55 deg.C

+59 deg.C

Correct! Wrong!

The INNER tanks:

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

Maintain equal fuel quantity by gravity.

Are each divided into four cells.

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!

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 unavailable.

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

Correct! Wrong!

The Airbus A330 fuel system:

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

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

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

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.

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

Check of block fuel automatically inserted in the FMGS.

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

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

Correct! Wrong!

Automatic refueling ensures that:

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

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

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

Correct! Wrong!

Electrical power requirements for refueling are:

Battery power is sufficient.

DC from external power or APU.

AC from external power or APU.

Correct! Wrong!

The L an R STBY PUMPS:

Automatically run when X-FEED is open.

Are located in the collector cells.

Are located outside of the collector cells.

Correct! Wrong!

Fuel temperature is:

Measured only in some tanks and displayed on ECAM.

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

Measured in all tanks and displayed on ECAM.

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!

Refueling can be accomplished:

Simultaneously from the right and left sides of the aircraft.

From the right side.

From the left side.

Correct! Wrong!

To supply both engines with X - FEED Valve OPEN:

One pump on each side is needed.

One pump on one side is sufficient.

Two pumps on same side are needed.

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!

When a tank fuel temperature is displayed amber:

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

FQI is degraded.

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

Correct! Wrong!

In ELEC EMER CONFIG:

X-FEED valve automatically opens.

X-FEED valve automatically closes.

X-FEED valve remains in the last position.

Correct! Wrong!

A fuel imbalance should be corrected:

Using X-FEED valve.

Using differential power settings.

Using the transfer pumps.

Correct! Wrong!

During manual fuel transfer from CTR to INNER Tank:

Center tank pumps are auto controlled to prevent overflow.

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

Crew must turn off Center Tank Pumps to prevent overflow.

Correct! Wrong!

Refueling can be controlled from:

The flight deck.

All statements are correct.

The refuel panel beneath the wing.

Correct! Wrong!

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

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

To destination.

30 minutes before the planned destination.

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

Correct! Wrong!
