DATA LINK
Notes:
Automatic page reversion following action on either UPLINK INSERT or
UPLINK CANCEL is similar to the one existing after manual wind
update.
If wind modifications exist and were either inserted or erased prior to
receive unsolicited wind uplink then wind modifications are lost.
If valid wind data was not uplinked into a specific phase (climb, cruise
or descent), the display for that phase reverts to current wind data. For
that phase, wind data are displayed in green font and the format (large
or small) is the same as the current state. The WIND REQUEST prompt
disappears but UPLINK INSERT / UPLINK CANCEL are displayed as on
other wind pages.
If the UPLINK INSERT and UPLINK CANCEL prompts are displayed on
MCDU pages at transition to done, these prompts are automatically
cleared.
If the FM loses communication with ACARS MU/ATSU, but has already
received a valid wind uplink, the wind uplink may still be inserted. If
communication cannot be regained after processing the uplink, the
WIND REQUEST prompt is not displayed.
If the uplinked message is invalid or a communication error occurs
which invalidates the pending uplink (e.g. a time-out occurs), the
display reverts to the state preceding the request transmission and any
previously existing data are redisplayed. The WIND REQUEST prompt
re appears. (
*
) is redisplayed provided that the FM can communicate
with ground.
Selection of the WIND REQUEST prompt without (
*
) symbol is rejected
and results in a NOT ALLOWED scratchpad message (white).
Attempting to clear at the WIND REQUEST prompt (regardless of
*
)
results in the display of the NOT ALLOWED message.
The wind data displayed on the F-PLN B page remains displayed when
a downlink request has been transmitted and an uplink response is
pending.
