LOGICAL ACKNOWLEDGEMENT |
[Issue: CS-ACNS/4]
EASA aviation regulations mandate that airborne data link systems must receive, process, and display specific Controller-Pilot Data Link Communications (CPDLC) uplink messages. These messages cover instructions like altitude changes, speed adjustments, route clearances, and frequency changes, ensuring safe and efficient air traffic control communication.
