[ 2R ] INIT REQUEST This prompt is displayed if the pilot did not enter an active flight plan or entered
a flight number or a company route that is not in the aircraft database. Selecting
this prompt sends the ground a request for active flight plan initialization (downlink
message). When the star is not displayed, a downlink message cannot be sent.
The uplink flight plan is automatically inserted in the active flight plan, prior to engine
start, provided an active flight plan does not exist.
After engine start, the uplink flight plan is sent to the secondary flight plan
and manually inserted or rejected. (Refer to DSC-22_20-70 FLIGHT PLAN
INITIALIZATION THROUGH ACARS).
[ 3R ] ALIGN IRS This field displays this legend only if the LAT and LONG fields are filled in, and
at least one of the inertial reference systems is in ALIGN status (IRS in NAV
position and alignment process not over). If the pilot presses this key when its field
is displaying this legend, the present coordinates are sent to the IRSs and this
completes the alignment process.
If one of the three IRSs indicates an ALIGN FAULT occurrence, the prompt becomes
REALIGN IRS.
[ 4R ] LONG This field displays the longitude of the departure airport reference point. The pilot
may modify by slewing or overwriting.
[ 5R ] WIND > The pilot presses this key in order to gain access to the climb wind page, unless
a temporary flight plan exists. In this case, the scratchpad displays TEMPORARY
F-PLN EXISTS.
[ 6R ] TROPO The default tropopause altitude is 36 090 ft. The pilot can use this field to modify it
(60 000 ft maximum).

WIND PAGES
Applicable to:
Winds in climb, cruise, descent and approach are necessary to provide the pilot with reliable
predictions and performance. Wind pages enable the pilot to enter and/or review the winds
propagated by the FMGS or sent by ACARS for the various flight phases.
Note: On 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.
