4. Procedure
Subtask 31-51-00-610-052-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 deletion 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 31-51-00-610-053-B

B. Deletion of the OEB REMINDER Data from the FWC1 data by data.

NOTE: You can delete all the OEB REMINDER Data in one operation (Ref. Para. 4. C).

NOTE: You can delete the OEB REMINDER Data only if the UPDATE CODE is entered (Ref. Para. 4. A. 7.)

ACTION	RESULT
	On the MCDU:
1.on the MCDU, push the line key adjacent to the DELETE indication.	the ECAM-1 or 2/OEB DATABASE UPDATE/DELETE page with a list of OEB data comes into view.
2.on the MCDU, with the NEXT PAGE key, find the OEB data to delete and push the line key adjacent to this OEB data.	a new page with only the data to delete comes into view.
3.on the MCDU, push the line key adjacent to the DELETE CONFIRM indication.	on the previous ECAM-1 or 2/OEB DATABASE UPDATE/DELETE page, the data goes out of view from the list. NOTE: If you push the line key adjacent to the RETURN indication, the deletion is not taken into account and the previous page with the total list of OEB data comes into view. NOTE: It is imperative to enter a new VERSION reference, only when the last data has been deleted from the list.
4.on the MCDU, once all modification have been inserted, with the MCDU keyboard, enter a new VERSION reference.	the new VERSION reference comes into view in the scratchpad line. NOTE: The VERSION reference must be different from the previous one. It is recommended to put the VERSION back to 000, if the FWC1 database is now empty.
5.on the MCDU, push the line key adjacent to the VERSION indication.	the VERSION reference comes into view.
6.on the MCDU, push the line key adjacent to the CONFIRM indication. NOTE: The line key adjacent to the CONFIRM indication is inactive if there is no deletion or if the VERSION reference is not entered.	if the VERSION reference is authorized the UPDATE COMPLETED message comes into view. NOTE: The INVALID DATA message comes into view if the deletion is faulty. (In this case it is necessary to enter again the step 6).

NOTE: If you push the line key adjacent to the RETURN indication before you do an action on the line adjacent to the CONFIRM indication.
The UPDATE WILL BE LOST message comes into view. If a new action is done on the line key adjacent to the RETURN indication, all the modifications are lost.

Subtask 31-51-00-610-054-B

C. DELETION of all OEB REMINDER Data into the FWC1 or 2.

NOTE: You can delete the OEB REMINDER Data only if the UPDATE CODE is entered (Ref . Para. 4. A. 7.)

ACTION	RESULT
	On the MCDU:
1.on the MCDU, push the line key adjacent to the DELETE ALL indication.	the ALL DATABASE page comes into view.
2.on the MCDU, push the line key adjacent to the DELETE CONFIRM indication.	the OEB DATABASE UPDATE page comes into view without OEB data but with the EMPTY DATABASE message in white. NOTE: If you push the line key adjacent to the RETURN indication, the deletion is not taken into account and the previous page comes into view. NOTE: It is imperative to enter a new VERSION reference (only when all modification have been inserted), it is recommended to put the VERSION back to 000, if the FWC database is now empty.
3.on the MCDU, with the MCDU keyboard, enter a new VERSION reference.	the new VERSION reference comes into view in the scratchpad line.
4.on the MCDU, push the line key adjacent to the VERSION indication.	the VERSION reference comes into view.
5.on the MCDU, push the line key adjacent to the CONFIRM indication. NOTE: The line key adjacent to the CONFIRM indication is inactive if there is no deletion or if the VERSION reference is not entered.	if the VERSION reference is authorized the UPDATE COMPLETED message comes into view. NOTE: The INVALID DATA message comes into view if the deletion is faulty. (In this case it is necessary to enter again the step 5).
