font. Wind data are modifiable during the cruise.
[ 5L ] SAT/ALT This field allows the pilot to enter a temperature at a given flight level, or
displays a propagated value.
The crew must enter both temperature and altitude at the first entry.
He can then modify independantly the temperature or the altitude.
[ 2R ] WIND
REQUEST*
Pressing this key sends a request for ACARS winds. (Refer to
DSC-22_20-70-B WIND DATA - REQUEST FOR WIND DATA)
[ 4R ] PREV PHASE This prompt is displayed in Preflight, Takeoff, Climb and Done phases.
Pressing this prompt calls up the CLIMB WIND page.
[ 5R ] NEXT PHASE Pressing this prompt calls up the DES WIND page.
Any new entry performed on the CRUISE WIND page is immediately inserted into the
corresponding flight plan. Predictions are dashed on the F-PLN pages during the recomputation
time. CRUISE WIND page reverts automatically to F-PLN page if a temporary flight plan is created
or the secondary flight plan is activated.

DESCENT WIND PAGE
This page allows the pilot to define and display the winds used for computing the descent profile.
The pilot calls it up by selecting NEXT PHASE on the CRUISE WIND page or WIND prompt on
VERT REV page.
[ 1L ] to [ 5L ] This field displays inserted winds or uplinked winds in large blue font prior
to activating the descent phase (modifiable values) and in green after
descent phase activation (non-modifiable values).
An entry of “GRND” in the “ALT” field is seen as the wind at ground level.
This wind is copied on the PERF APPR page (and corrected for the
magnetic variation).
A clear action on one key reverts the line to blue bracket.
[ 6L ] ALTERNATE This field is displayed only when an alternate is defined.
The pilot-entered value or uplinked value is displayed in large blue font.
Always modifiable by the pilot.
[ 2R ] WIND
REQUEST*
Pressing this key sends a request for ACARS winds (Refer to
DSC-22_20-70-B WIND DATA - REQUEST FOR WIND DATA). This
prompt is active only on ACARS or ATSU equipped aircraft.
[ 4R ] PREV PHASE Pressing this key calls up the CRUISE WIND page. The field is erased
after the top of descent has sequenced.
Note: Descent winds and alternate wind are deleted, if the destination airport is changed.

INIT B PAGE
Applicable to:
The pilot uses this page to initialize gross weight and center of gravity before starting the engines.
The pilot can call it up from the INIT A page, by pressing the [ → ] key on the MCDU console, as long
as engines have not been started.
This page automatically reverts to the FUEL PRED page after the first engine is started. The FMGS
computes its predictions, based on the FOB indicated by the FCMC (or FE as backup) from that
moment on.
[ 1L ] TAXI This is the taxi fuel, which defaults to a preset value, (usually 400 kg). The
pilot can change the value through this field.
[ 2L ] TRIP/TIME
(green)
This field displays trip fuel and time when predictions become available.
The pilot cannot modify this data.
[ 3L ] RTE RSV/%
(blue)
This field displays the reserve fuel for the route and the corresponding
percentage of trip fuel. It may be blank, if such is the policy of the operator.
The pilot can either enter a route reserve, or a percentage, and the system
then automatically computes the nominal value.
[ 4L ] ALTN/TIME
(green)
This field displays alternate trip fuel and time, assuming that the Cost Index
= 0 and that the aircraft flies at the default cruise flight level. This field
displays information in small font, and the flight crew cannot modify it.

[ 5L ] FINAL/TIME This field displays the hold fuel and time, associated with continued flight
to the alternate airport (or destination airport, if selected in the “airline fuel
policy” section of the database). The pilot may enter a final fuel or time, and
the system will compute associated holding time/fuel available.
The system assumes that the holding will be in a racetrack pattern, 1 500 ft
