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

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!

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

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

Check of block fuel automatically inserted in the FMGS.

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

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!

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!

In ELEC EMER CONFIG:

X-FEED valve remains in the last position.

X-FEED valve automatically closes.

X-FEED valve automatically opens.

Correct! Wrong!

The INNER tanks:

Maintain equal fuel quantity by gravity.

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

Are each divided into four cells.

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.

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

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).

30 minutes before the planned destination.

To destination.

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!

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 controlled from:

All statements are correct.

The refuel panel beneath the wing.

The flight deck.

Correct! Wrong!

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

All statements are correct.

Left pump 2 remains powered.

The X-FEED valve automatically opens.

Correct! Wrong!

In case of Fuel Center Pumps fault:

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

Center Tank fuel is unavailable.

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

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!

When a tank fuel temperature is displayed amber:

FQI is degraded.

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

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

Correct! Wrong!

During manual fuel transfer from CTR to INNER Tank:

Crew must turn off Center Tank Pumps to prevent overflow.

Center tank pumps are auto controlled to prevent overflow.

Center tank transfer should not be started until inner tanks will hold all the fuel.

Correct! Wrong!

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!

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!

In case of loss of both Fuel Control Monitoring Computers:

Fuel transfers must be manual.

Auto-trim is lost.

Automatic transfer is degraded but it is still available.

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.

One is running and one is in stand-by depending on which engine has been starting first.

Both are running.

Correct! Wrong!

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!

Refueling can be accomplished:

Simultaneously from the right and left sides of the aircraft.

From the left side.

From the right side.

Correct! Wrong!

Maximum fuel temperature for JET A and JET A1 is:

+62 deg.C

+55 deg.C

+59 deg.C

Correct! Wrong!
