A. IR Alignment from the ADIRS CDU

ACTION RESULT
1. On the ADIRS CDU:
-  set the three OFF/NAV/ATT selector switches to NAV
On the ADIRS CDU:
-  the OFF legend of the ADR1, ADR2 and ADR3 pushbutton switches stays off.

-  the ON BAT light stays on for 5 seconds.

-  the ALIGN legend comes on.

After approximately 40 seconds:
-  on the CAPT and F/O PFDs:
. the ATT warning flags go out of view.
. the attitude data come into view.

-  on the upper ECAM display unit, the memo section shows IRS IN ALIGN > 7 MN.

-  set the DATA DISPLAY selector switch to PPOS

-  set the SYS DISPLAY selector switch to 1

-  on the CDU keyboard, enter the present position (example for Toulouse):
N 43 36' 8'' then push the ENT key,
E 1 21' 9'' then push the ENT key.

NOTE: If the coordinates are incorrect, push the CLR key and enter new data as above.
NOTE: If an incorrect longitude is entered two times in sequence during PPOS entry, the ADIRU's will accept this position until the subsequent alignment.
The ADIRS CDU shows the coordinates
N 43-36-8 (in the left part of the display) and
E 1-21-9 (in the right part of the display).
-  set the SYS DISPLAY selector switch to 2, then to 3 and make sure that the coordinates shown are the same for the three ADIRUs. Set the SYS DISPLAY selector switch to 1.
After a time delay of approximately 5 minutes:
-  on the CAPT and F/O NDs , the HDG warning flags go out of view and the heading dial comes into view.

After a time delay of approximately 10 minutes:
-  on the ADIRS CDU, the ALIGN legend of the IR1, IR2 and IR3 annunciators goes off

-  on the upper ECAM display unit, the IRS IN ALIGN 1 MN indication goes out of view (the ADIRUs are in the NAV mode).
