previous one.
Wind data can be cleared, the field reverts to brackets.
All winds except the PERF APPR page wind (Tower wind) are true north referenced.
ENTERING THE HISTORY WIND (F-PLN INITIALIZATION)
The pilot may insert the history wind but cannot modify this page. If convenient, PRESS the (6R)
prompt to insert. After insertion, the [6R] prompt is suppressed but the page still displays the
wind values for information.
ENTERING THE CLIMB WIND (F-PLN INITIALIZATION)
If previous history winds are not convenient or have to be modified :
SELECT CLIMB WIND page from INIT A page or VERT REV page.
WRITE new winds into the scratchpad and ENTER

CLIMB WIND cannot be modified when the climb phase is active. At climb phase transition,
wind data switch from blue to green colour and any attempted modification will trigger the “NOT
ALLOWED” message.
The system interpolates winds between 2 entered levels.
ENTERING THE CRUISE WINDS
At flight plan initialization the cruise wind page displays all cruise waypoints with empty brackets.
In flight, only down path waypoints are displayed.
SELECT VERT REV at WPT
PRESS the WIND prompt

SLEW until relevant waypoint is displayed.
WRITE and ENTER the new wind data into the scratchpad.
WIND may be entered through ACARS pages system. (Refer to DSC-22_20-70-B WIND DATA -
PROCEDURE TO INSERT WIND DATA)
The crew will modify the entered winds in flight if a significant difference is expected (greater than
30 kt or 30 °).
Note: Cruise ‐ wind may be entered directly into F-PLN B page. These entries are
automatically transferred to cruise wind page.
‐ The CRUISE WIND page displays only ACARS or crew entered data. It never displays
computed or propagated data (F-PLN B page only).
ENTERING A STEP CLIMB/STEP DESCENT WIND
If a step climb or a step descent is scheduled, the wind at the step level shall be entered for
prediction purposes.
SELECT CRUISE WIND page.
Slew until the step waypoint is displayed.
WRITE the wind into the scratchpad and ENTER.

If the pilot does not enter the step wind, the FMGS continues to use the wind entered for the cruise
flight level.
Clearing the manual entry reverts to brackets, but the FMGS will use the wind at cruise flight level
for predictions and performance.
ENTERING THE DESCENT WINDS
The pilot will enter as many as one wind at 5 different FL or altitudes. This wind data will be used
for descent profile and prediction computation.
From the vertical revision page or from the CRUISE WIND page :
PRESS the WIND prompt.
SELECT the DESCENT WIND page.
ENTER up to 5 different “wind/altitude”.
Note: It is recommended that at least one descent wind be entered at cruise FL. If no wind is
entered, the system will assume a zero wind value (displayed on F-PLN B page) at TOD.

A wind is written as true direction/velocity/flight level or altitude in feet.
If the crew enters “GRND” in the altitude field, the system uses the associated wind as wind at
destination.
The descent profile is corrected as well as the tower wind entered in the PERF APPR page. (The
wind direction is then modified of the magnetic variation).
When the winds have been entered, the F-PLN B page displays the forecast wind profile at all
descent waypoints using values it has interpolated from manual entries. Descent winds are not
modifiable when descent, approach or go around phase is active. At descent phase transition,
wind data switch from blue to green colour and any attempted modification triggers the “NOT
ALLOWED” message.
