It is very important that all the ANSP, companies and pilots use this kind of digital communication.
(Controller-Pilot Data Link Communications): CPDLC is a digital communication system that enables text-based exchanges between air traffic controllers and pilots, reducing reliance on traditional voice radio communication. It is particularly useful in congested airspaces and areas with limited radio coverage, such as over oceans. CPDLC enhances communication accuracy, reduces misunderstandings, and provides a record of messages for reference. It supports routine tasks like clearances and route adjustments, improving overall air traffic management and safety.
