Automatic position report
The automatic POSITION REPORT does not require pilot action.
A POS uplink message is sent by ground to specify reporting points of
the ACTIVE F-PLN over which a POS report should be automatically
downlinked.
If a POS uplink is received and a F-PLN Initialization is pending for the
active flight plan, then the POS uplink is buffered until the F-PLN has
been initilalized and processed or invalidated. No message is displayed.
If the ACTIVE F-PLN is not defined, the uplink message is directed to
the SEC F-PLN.
If a F-PLN INIT request is pending for the SEC F-PLN, the POS uplink is
buffered.
If the SEC F-PLN is also undefined, then the POS uplink is rejected.
Progress report
The Progress Report message (PRG) provides data relative to ETA and
EFOB at the destination.
This message is sent in response to a ground request for progress
report or automatically upon crossing a designated trigger.
Specific trigger values may be customized by the airline in the AMI file.
The PRG downlink cannot be sent manually through a dedicated
prompt. However, the message may result from a pilot action (e.g.
changing the destination or runway at destination).
Only Progress reports relative to the ACTIVE F-PLN are transmitted.
