CPDLC (controller pilot data link communications) is a two-way data-link system by which controllers can transmit non-urgent strategic messages to an aircraft as an alternative to voice communications. The message is displayed on a flight deck visual display. The CPDLC application provides air-ground data communication for the ATC service.
Limitations:
CPDLC mandated in European airspace per February 5th, 2020
Less communication on the ATC frequency;
Increased sector capacities;
More pilot requests can be dealt with simultaneously;
Reduced probability of miscommunication (e.g. due call sign confusion);
Safer frequency changes, hence fewer loss of communication events.
