Correct! Wrong!

Automatic refueling ensures that:

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

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

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

Correct! Wrong!

When landing gear is up and slats in.

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

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

Correct! Wrong!

In normal operation, engines are always fed from:

CTR Tank for takeoff.

INNER Tanks.

OUTER Tanks in case of overfull condition.

Correct! Wrong!

Electrical power requirements for refueling are:

AC from external power or APU.

Battery power is sufficient.

DC from external power or APU.

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!

Refueling can be controlled from:

The flight deck.

The refuel panel beneath the wing.

All statements are correct.

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:

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

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

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

Correct! Wrong!

Minimum fuel quantity for takeoff is:

5 600 kg (12 346 lb).

4 500 kg (9 921 lb).

5 200 kg (11 461 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 depending on which engine has been starting first.

Both are running.

One is running and one is in stand-by.

Correct! Wrong!

Maximum fuel temperature for JET A and JET A1 is:

+62 deg.C

+59 deg.C

+55 deg.C

Correct! Wrong!

In case of loss of both Fuel Control Monitoring Computers:

Fuel transfers must be manual.

Automatic transfer is degraded but it is still available.

Auto-trim is lost.

Correct! Wrong!

Refueling can be accomplished:

From the left side.

Simultaneously from the right and left sides of the aircraft.

From the right side.

Correct! Wrong!

In ELEC EMER CONFIG:

X-FEED valve automatically closes.

X-FEED valve remains in the last position.

X-FEED valve automatically opens.

Correct! Wrong!

A fuel imbalance should be corrected:

Using differential power settings.

Using the transfer pumps.

Using X-FEED valve.

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!

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).

The CTR tank is empty.

At least one CTR pump has failed.

Correct! Wrong!

When a tank fuel temperature is displayed amber:

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

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

FQI is degraded.

Correct! Wrong!

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

Slightly more than 1 hour.

Between 33 minutes and 35 minutes.

Between 20 minutes and 25 minutes.

Correct! Wrong!

To supply both engines with X - FEED Valve OPEN:

Two pumps on same side are needed.

One pump on one side is sufficient.

One pump on each side is needed.

Correct! Wrong!

The INNER tanks:

Are each divided into four cells.

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

Maintain equal fuel quantity by gravity.

Correct! Wrong!
