Abstract: To facilitate improved Controller-Pilot Data Link Communication (CPDLC) interfacing, report messages can be automatically armed and displayed in a threaded message format in the same message panel with other CPDLC messages between a vehicle and a ground system. Upon determining that a report is needed based on an uplink CPDLC message from the ground system, a report message label is displayed on the CPDLC message panel. Once the report is ready, it is automatically armed and the report message label indicates to the operator that the report message is ready to be sent. The operator can also select the report message label in the message panel to display the report message.
