3.5.6 ATC MSG LOG
This information is common to FANS 1/A+ and ATN B1.
The ATC MSG LOG captures ATC and ATS uplink and downlink messages for the current flight in
chronological order. The log file does not retain normal responses to controller uplinks; however, it
does save responses if there is a delay in aircrew downlink or if the message is aborted.
Figure 3-21 ATC MSG LOG
The message log or an individual message detail can be printed. Closed or sent messages can be
selectively deleted. Aircrew can delete ATC MSG LOG entries with the following status:
• CLOSED
• SENT
• ABORTED
• ACCEPTED
• REJECTED
To delete an entry
• Press the DEL key (DELETE appears in the scratchpad) and then press the LSK (R1 to R5) for the
respective message.
When the aircraft status is ON GROUND, and the ORIGIN or destination is no longer valid, the
ATC MSG LOG clears automatically.
ATC MSG DETAIL
By selecting an individual message, the aircrew can view the complete formatted message, the
facility, the status, and if applicable, the message response. An uplink message can have up to 10
pages in the detail view.
