Study Notes

Refueling Procedure for A330-200/300

Before refueling, engage the parking brake, place chocks behind the tires, and ensure the chocks do not touch the tires.
With the ADIRU in NAV position, open the Refuel panel access door on the lower fuselage.
Set the PoWeR SUPPLY to BATtery if needed.
Conduct a Hi-Level test: Hi-level & overflow lights change state, CoCkPiT & END lights illuminate, and fuel quantity displays show all 8's for preselected and actual values.
Increase (INC) the preselected value using the load switch, setting it to the total fuel quantity required.
Verify refuel valve switches are in the normal and guarded position.
Engage the mode select switch to REFUEL. Fuel quantity and ACTUAL values should increase.
The END light illuminates steadily when refueling is complete.
Ensure the actual and preselected values agree within ± 200 kg. A white cross should be visible on a black background, its absence suggests a potential issue with the tank venting system.
Connect a bonding cable between the fuel tanker and a grounding point on the aircraft (nose or main gear), and another grounding cable from the aircraft to the ground.
If the refueling process is aborted, information on system status is found in the FCMC REFUEL PARAMETERS menu on the MCDU.

Fuel Tank Drain (D/O)

Each fuel tank is integrated into the aircraft's structure.
To refuel, push and hold the plunger on the valve; fuel pressure from the tanker/pump opens the valve.
Monitor fuel quantity with the standard indication system.
Release the plunger to close the valve when the desired quantity is reached.

Mel/Deactivation - Refuel Isolation Valve Failure

This failure can be addressed through a MEL (Minimum Equipment List).

Mel/Deactivation - Fuel Quantity Indication Failure

The aircraft may be dispatched with unserviceable fuel quantity indications, as this condition can be managed using a MEL.
