[ 2L ] LAT (blue) This field displays the latitude of the reference point of the departure
airport. The crew can modify the altitude by slewing or overwriting it.
[ 6L ] RETURN This prompt enables the crew to return to the INIT A page.
[ 1R ] ALIGN IRS (amber) This field only displays this legend, if the LAT and LONG fields are
filled in, and at least one of the inertial reference systems is in ALIGN
status (IRS selectors in NAV position, and the alignment process not
completed). When the crew presses the “ALIGN IRS →“ prompt, the
coordinates displayed in the LAT and LONG fields are sent to the
IRSs. This completes the alignment process. If one of the three IRSs
indicates an ALIGN FAULT occurence, the prompt becomes REALIGN
IRS.
[ 2R ] LONG (blue) This field displays the longitude of the reference point of the departure
airport. The crew can modify it by slewing, or overwriting.

propagated by the FMGS or sent by ACARS for the various flight phases.
Note: On the WIND pages, wind direction is always true-referenced.
CLIMB WIND PAGE
This page enables the pilot to enter and/or review predicted wind vectors (direction and velocity) at
up to 5 different levels.
THE CLIMB WIND PAGE IS ACCESSED FROM :
TITLE "CLIMB WIND" is displayed in large white font.
