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

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!

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

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.

Check of block fuel automatically inserted in the FMGS.

Correct! Wrong!

Maximum fuel temperature for JET A and JET A1 is:

+59 deg.C

+62 deg.C

+55 deg.C

Correct! Wrong!

Refueling can be controlled from:

The refuel panel beneath the wing.

The flight deck.

All statements are correct.

Correct! Wrong!

In normal conditions, the automatic control of CG begins:

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%.

When landing gear is up and slats in.

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 20 minutes and 25 minutes.

Between 33 minutes and 35 minutes.

Correct! Wrong!

The L an R STBY PUMPS:

Are located in the collector cells.

Automatically run when X-FEED is open.

Are located outside of the collector cells.

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!

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!

Electrical power requirements for refueling are:

DC from external power or APU.

Battery power is sufficient.

AC from external power or APU.

Correct! Wrong!

A fuel imbalance should be corrected:

Using the transfer pumps.

Using differential power settings.

Using X-FEED valve.

Correct! Wrong!

FAULT lights up on both CTR Tank pbs when:

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).

At least one CTR pump has failed.

Correct! Wrong!

In case of loss of both Fuel Control Monitoring Computers:

Automatic transfer is degraded but it is still available.

Auto-trim is lost.

Fuel transfers must be manual.

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!

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!

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

The X-FEED valve automatically opens.

All statements are correct.

Left pump 2 remains powered.

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 operation, the automatic control of CG will stop:

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)

To destination.

Correct! Wrong!

In ELEC EMER CONFIG:

X-FEED valve automatically opens.

X-FEED valve remains in the last position.

X-FEED valve automatically closes.

Correct! Wrong!

The Airbus A330 fuel system:

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

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.

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!

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 case of Fuel Center Pumps fault:

Center Tank fuel is unavailable.

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.

Correct! Wrong!

During manual fuel transfer from CTR to INNER Tank:

Center tank pumps are auto controlled to prevent overflow.

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.

Correct! Wrong!

The INNER tanks:

Maintain equal fuel quantity by gravity.

Are each divided into four cells.

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

Correct! Wrong!
