ALIGNMENT OF INERTIAL REFERENCE SYSTEM
The FMGS uses the reference point coordinates of the departure airport to align the IRS.
It calls these up from the database automatically after the flight crew has entered a
company route or an origin-destination city pair and pressed the ALIGN IRS key. The flight
crew can adjust these coordinates manually to the gate position. A normal alignment takes
ten minutes, a fast alignment 30 seconds.
Fast alignment is used to refine a position when time is limited.

Note: If the ADIRS overhead CDU flashes "ALIGN" during the alignment process, it
indicates one of the following :
It has detected excessive motion. (It automatically restarts the alignment).
It has detected a mismatch between the position the MCDU has sent to the IRS
and the last memorized IRS position. The pilot must order the MCDU to send a new
position to the IRS.
It has detected a mismatch between the latitude the MCDU has sent to the IRS
and the latitude the IRS has computed during the alignment.
The IRS has not received a position from the MCDU or the ADIRS overhead CDU.
