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

In normal conditions, the automatic control of CG begins:

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

When landing gear is up and slats in.

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

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 depending on which engine has been starting first.

One is running and one is in stand-by.

Both are running.

Correct! Wrong!

A fuel imbalance should be corrected:

Using the transfer pumps.

Using differential power settings.

Using X-FEED valve.

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!

When a tank fuel temperature is displayed amber:

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

FQI is degraded.

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

Correct! Wrong!

In normal operation, engines are always fed from:

INNER Tanks.

OUTER Tanks in case of overfull condition.

CTR Tank for takeoff.

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!

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!

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!

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!

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!

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!

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!

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!

The Airbus A330 fuel system:

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

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

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).

4 500 kg (9 921 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 case of Fuel Center Pumps fault:

Center Tank fuel is unavailable.

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

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

Correct! Wrong!

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

To destination.

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

30 minutes before the planned destination.

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

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!

Refueling can be controlled from:

All statements are correct.

The refuel panel beneath the wing.

The flight deck.

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!

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).

At least one CTR pump has failed.

The CTR tank is empty.

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!
