Airbus A330 – Fuel - SmartCockpit - Airline training guides, Aviation, Operations, Safety

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!

In normal operation, engines are always fed from:

INNER Tanks.

CTR Tank for takeoff.

OUTER Tanks in case of overfull condition.

Correct! Wrong!

FAULT lights up on both CTR Tank pbs when:

At least one CTR pump has failed.

The CTR tank is empty.

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

Correct! Wrong!

To supply both engines with X - FEED Valve OPEN:

One pump on each side is needed.

Two pumps on same side are needed.

One pump on one side is sufficient.

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 depending on which engine has been starting first.

One is running and one is in stand-by.

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!

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!

Fuel temperature is:

Measured in all tanks and displayed on ECAM.

Measured only in some tanks and displayed on ECAM.

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

Correct! Wrong!

Refueling can be controlled from:

The flight deck.

All statements are correct.

The refuel panel beneath the wing.

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!

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:

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

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.

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.

Between 20 minutes and 25 minutes.

Slightly more than 1 hour.

Correct! Wrong!

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

30 minutes before the planned destination.

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

To destination.

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

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!

In ELEC EMER CONFIG:

X-FEED valve remains in the last position.

X-FEED valve automatically closes.

X-FEED valve automatically opens.

Correct! Wrong!

A fuel imbalance should be corrected:

Using differential power settings.

Using X-FEED valve.

Using the transfer pumps.

Correct! Wrong!

In case of Fuel Center Pumps fault:

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

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

Center Tank fuel is unavailable.

Correct! Wrong!

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

Left pump 2 remains powered.

All statements are correct.

The X-FEED valve automatically opens.

Correct! Wrong!

Maximum fuel temperature for JET A and JET A1 is:

+62 deg.C

+59 deg.C

+55 deg.C

Correct! Wrong!

Minimum fuel quantity for takeoff is:

4 500 kg (9 921 lb).

5 200 kg (11 461 lb).

5 600 kg (12 346 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 normal conditions, the automatic control of CG begins:

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

When landing gear is up and slats in.

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

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.

Crew must turn off Center Tank Pumps to prevent overflow.

Center tank pumps are auto controlled to prevent overflow.

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!

Refueling can be accomplished:

Simultaneously from the right and left sides of the aircraft.

From the left side.

From the right side.

Correct! Wrong!
