Controller-Pilot Data Link Communications (CPDLC)

Controller-Pilot Data Link Communications (CPDLC), which operates within MUAC’s trajectory-based flight data processing system, is an air/ground data link application which enables the exchange of clearances, SSR code changes, changes of frequencies, etc. between controllers and pilots.

In addition to the clear operational benefits offered each day by CPDLC (no misunderstanding of messages, a second communication channel, shared workload on the ground), the technology also offers great potential for future ground-breaking technologies such as i4D (initial four dimensional) operations.
