Climb Wind page revisions
For the ACTIVE F-PLN, the HISTORY WIND prompt remains available.
HISTORY WINDS may be viewed and inserted. However, while a wind
request is pending or while uplinked climb winds have not yet been
inserted or erased, any inserted HISTORY WINDS are not available for
display on the active CLIMB WIND page.
The following rules apply to the ACTIVE F-PLN and SEC F-PLN when
created by a COPY ACTIVE.
−
If the UPLINK INSERT or the UPLINK CANCEL prompts have not been
selected on the CLIMB WIND page when flight phase transitions to
climb, the display reverts to the current climb winds.
−
If the UPLINK INSERT and UPLINK CANCEL prompts are displayed on
the CLIMB WIND page at transition to climb flight phase, these
prompts are automatically cleared if there is no more uplinked data
for others phase (cruise, descent and alternate uplink winds).
Otherwise, they are still displayed.
−
The WIND REQUEST prompt remains available for selection on the
CLIMB WIND pages during climb flight phase, per normal rules.
However, uplinked climb winds cannot overwrite currently displayed
climb winds in climb phase. Any climb wind uplink is ignored and the
dashes are replaced with the current climb winds.
Cruise Wind page revisions
There may be additional or fewer WPTs in the cruise wind uplink than
currently defined in the F-PLN. Some (or all) WPTs in the uplink
message may not exist in the F-PLN. In this case only the wind data for
the matching cruise WPTs in the associated F-PLN are displayed for
pilot review; the others are discarded. Pressing the UPLINK INSERT
prompt inserts data only for matching cruise WPTs.
If the last CRZ WPT is sequenced or the flight phase transitions to
descent, approach, or go around, the uplinked cruise wind data are
lost. If the CRUISE WIND page is displayed in either of these cases, the
page switches automatically to the DESCENT WIND page.
The same rules apply to SEC F-PLN.
For a flight phase transition from CRZ to CLB, the new set of cruise
WPTs may cause some uplinked cruise wind data to be discarded.
The WIND REQUEST prompt remains available for selection on the
CRUISE WIND pages during cruise phase. A new cruise winds message
may replace existing cruise data for all applicable, down path cruise
waypoints.
If wind data has not been received for an uplinked WPT at a given
altitude, the TRU WIND field is blanked.
Propagation of wind data to downpath WPTs occurs, based on new
uplinked cruise wind data. Thus pilot can preview the overall wind
model data (uplinked and propagated), for all cruise WPTs, before
insertion or cancellation.
