4. Procedure
Subtask 31-51-00-610-055-B

A. Access to the ECAM OEB DATABASE UPDATE Menu

NOTE: The procedure below is applicable to each MCDU. The actions and results of this procedure occur on the MCDU used.

NOTE: If the response time of the FWCs is more than 1 second a IN PROGRESS message comes into view.

(1) Access to the ECAM OEB DATABASE UPDATE menu and update CODE

ACTION	RESULT
	On the MCDU:
1.on one of the MCDUs, turn the OFF/BRT knob.	the MCDU is on.
2.on the MCDU, push the MCDU MENU mode key.	the MCDU MENU page comes into view.
3.on the MCDU, push the line key to the CFDS indication.	the CFDS MENU page comes into view.
4.on the MCDU, push the line key adjacent to the SYSTEM REPORT/TEST indication.	the SYSTEM REPORT/TEST menu page comes into view.
5.on the MCDU, push the line key adjacent to the INST indication.	the instruments menu page comes into view.
6.on the MCDU, push the line key adjacent to the ECAM indication.	the first ECAM page comes into view. NOTE: For FWC1 database updating enter in the ECAM 1 menu. For FWC2 database updating enter in the ECAM 2 menu.
7.on the MCDU, push the line key adjacent to the OEB DATABASE indication.	the ECAM-1 or 2/OEB DATABASE page comes into view. NOTE: If the data base of the FWC1 or FWC2 is not valid, the VERSION is replaced by XXX and the check sum is replaced by XXXXX adjacent to the FWC1 or FWC2 indication. NOTE: If the opposite FWC does not respond, the NO RESPONSE message comes into view adjacent to the FWC1 or 2 indication.
8.on the MCDU, with the MCDU keyboard, enter the code TWIN. NOTE: The crossloading of the FWC data base is possible only if the UPDATE CODE is entered.	the code TWIN comes into view in the scratchpad line.
9.on the MCDU, push the line key adjacent to the UPDATE CODE indication.	if the code is valid, the ECAM-1 or 2/OEB DATABASE UPDATE page comes into view. NOTE: If the code not valid, the INVALID DATA message comes into view on the ECAM-1 or 2/OEB DATABASE page.

Subtask 31-51-00-610-056-B

B. Crossloading

NOTE: You can do the crossloading only if the UPDATE CODE is entered (Ref. Para. 4. A.)

(1) Crossloading from FWC1 or FWC2

ACTION	RESULT
	On the MCDU:
1.on the MCDU, push the line key adjacent to the CROSSLOAD FROM FWC1 or FWC2 indication.	the CROSSLOAD FROM FWC1 or FWC2 page comes into view, with the messages READY FOR CROSSLOAD and UPDATE OF FWC2 or FWC1. NOTE: If the FWC1 or FWC2 does not respond, the UNABLE TO CROSSLOAD message comes into view.
2.on the MCDU, push the line key adjacent to the CONFIRM indication.	the message CROSSLOAD COMPLETED comes into view. NOTE: if the message CROSSLOAD FAILED comes into view, do a new crossloading (Ref. Para. 4. A.).

NOTE: The VERSION reference of the FWC2 or FWC1 is automatically put in accordance with the opposite FWC.

Subtask 31-51-00-740-052-B

C. Check of the Crossloaded OEB Data with the Flight Crew Operating Manual (FCOM) "OEB Operations Engineering Bulletins" Section
(1) Print the OEB REMINDER lists

ACTION	RESULT
	On the MCDU:
1.On the MCDU, push the line key adjacent to the RETURN indication until the ECAM-2 or 1/OEB DATABASE page comes into view.	the ECAM-1 or 2/OEB DATABASE page is shown.
2.on the MCDU, push the line key adjacent to the LIST FWC2 or FWC1 indication.	the first ECAM-2 or 1/OEB DATABASE/ FWC2 or 1 LIST XXX page comes into view (where XXX is the VERSION reference, for example: 05A).
3.on the MCDU, push the line key adjacent to the PRINT indication.	the first ECAM-2 or 1/OEB DATABASE/ FWC2 or 1 LIST XXX page is printed. NOTE: If there is more than one page, it is necessary on the MCDU: to push the NEXT PAGE function key to get access to all the pages to push the line key adjacent to the PRINT indication on each page to have the total list.

(2) Do a check of the printed OEB list with the ECAM warnings and their codes given in the FCOM Preliminary Pages (List of Effective Operations Engineering Bulletin) or with the ECAM alert title (if displayed) and the Quick Reference Handbook (QRH).
(a) Make sure that the printed OEB data agrees with the data in the FCOM "OEB Operations Engineering Bulletins" section.
If the data does not agree, do the applicable procedure:
- loading (Ref. Para 4. B of this procedure), or
- deletion (Ref. AMM TASK 31-51-00-610-002), or
- crossloading (Ref. AMM TASK 31-51-00-610-003).
(b) When the check is correct, keep the OEB REMINDER list in the QRH, in the cockpit.

5. Close-up
Subtask 31-51-00-860-058-B

A. Put the aircraft back to its initial configuration.
(1) On the MCDU, push the line key adjacent to the RETURN indication until the CFDS MENU page comes into view.
(2) Do the EIS stop procedure (Ref. AMM TASK 31-60-00-860-002)
(3) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002)
(4) Put the system back to the serviceable condition.
