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

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

Check of block fuel automatically inserted in the FMGS.

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

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

Correct! Wrong!

In case of loss of both Fuel Control Monitoring Computers:

Auto-trim is lost.

Fuel transfers must be manual.

Automatic transfer is degraded but it is still available.

Correct! Wrong!

The Airbus A330 fuel system:

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

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.

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!

Refueling can be accomplished:

Simultaneously from the right and left sides of the aircraft.

From the left side.

From the right side.

Correct! Wrong!

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!

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!

In normal operation, engines are always fed from:

OUTER Tanks in case of overfull condition.

INNER Tanks.

CTR Tank for takeoff.

Correct! Wrong!

Electrical power requirements for refueling are:

DC from external power or APU.

AC from external power or APU.

Battery power is sufficient.

Correct! Wrong!

Refueling can be controlled from:

The refuel panel beneath the wing.

The flight deck.

All statements are correct.

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!

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!

Maximum fuel temperature for JET A and JET A1 is:

+62 deg.C

+55 deg.C

+59 deg.C

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!

A fuel imbalance should be corrected:

Using the transfer pumps.

Using differential power settings.

Using X-FEED valve.

Correct! Wrong!

The L an R STBY PUMPS:

Are located in the collector cells.

Are located outside of the collector cells.

Automatically run when X-FEED is open.

Correct! Wrong!

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

To destination.

30 minutes before the planned destination.

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

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

Correct! Wrong!

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!

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!

The INNER tanks:

Are each divided into four cells.

Maintain equal fuel quantity by gravity.

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

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!

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!

Fuel temperature is:

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

Measured only in some tanks and displayed on ECAM.

Measured in all tanks and displayed on ECAM.

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!
