4. Procedure
Subtask 12-11-28-860-072-A ** ON A/C NOT FOR ALL

A. Get Access to the Fuel Quantity Indication Computer (FQIC) Input Parameters Page 1

NOTE: This procedure can only be used if:

the PITCH and ROLL data is taken from the ADIRS (identified by an A after the PITCH and ROLL title)
the PITCH data displayed for the LEFT, CTR and RIGHT is no more or less than 0.1 of each other
the ROLL data displayed for the LEFT, CTR and RIGHT is no more or less than 0.1 of each other.

NOTE: The FQIS input parameter pages are not automatically updated. The operation of the Fuel System can be monitored through the Centralized Fault Display System (CFDS) input parameter pages. The pages must be continuously updated. Use the NEXT PAGE control on the Multipurpose Control and Display Unit (MCDU) to cycle the pages to update the screen.

(1) When the SYSTEM REPORT/TEST Menu page comes into view, do this procedure:

ACTION	RESULT
1.Push the line key adjacent to the FUEL indication.	the FUEL Main Menu first page comes into view.
2.On the MCDU control panel push the NEXT PAGE key.	the FUEL Main Menu second page comes into view.
3.Push the line key adjacent to the INPUT PARAMETER VALUES indication.	the MCDU shows the page FQIS INPUT PARAMETERS - RECORD THE PITCH AND ROLL DATA.

(2) In Table 1, use the PITCH data to find the equivalent number.
(3) In Table 1, use the ROLL data to find the equivalent letter.
(4) Put together the number and the letter to identify the square to use in the Magnetic Level Indicator (MLI) procedure (Ref. AMM TASK 12-11-28-650-007).

Subtask 12-11-28-860-072-B ** ON A/C NOT FOR ALL

A. Get Access to the FQIC Input Parameters Page 1

NOTE: This procedure can only be used if:

the PITCH and ROLL data is taken from the ADIRS (make sure that the FQIS Status page does not show "NO DATA FROM ADIRU 1" and "NO DATA FROM ADIRU 2")
the PITCH data displayed for the LEFT, CTR and RIGHT is no more or less than 0.1 of each other
the ROLL data displayed for the LEFT, CTR and RIGHT is no more or less than 0.1 of each other.

NOTE: The FQIS input parameter pages are automatically updated every 5.5 seconds.

(1) When the SYSTEM REPORT/TEST Menu page comes into view, do this procedure:

ACTION	RESULT
1.Push the line key adjacent to the FUEL indication.	the FUEL Main Menu first page comes into view.
2.On the MCDU control panel push the NEXT PAGE key.	the FUEL Main Menu second page comes into view.
3.Push the line key adjacent to the INPUT PARAMETER VALUES indication.	the MCDU shows the page FQIS INPUT PARAMETERS - RECORD THE PITCH AND ROLL DATA.

(2) In Table 1, use the PITCH data to find the equivalent number.
(3) In Table 1, use the ROLL data to find the equivalent letter.
(4) Put together the number and the letter to identify the square to use in the MLI procedure (Ref. AMM TASK 12-11-28-650-007).

A. Aircraft Maintenance Configuration
(1) Put the aircraft back to its initial configuration.
(a) On the MCDU, push the line key adjacent to the RETURN indication until the MCDU Menu page comes into view.
(b) On the MCDU, set the BRT knob to OFF.
(c) Do the ADIRS stop procedure (Ref. AMM TASK 34-10-00-860-005).
(d) Do the EIS stop procedure (Ref. AMM TASK 31-60-00-860-002).
(e) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).
