CPDLC stands for?

• A. Controller Pilot Data Link; Alternative to voice communications
• B. Central Pilot Data Link
• C. Controller Pilot Data Link Only
• D. Communications Pilot Data Link

Answer: (A)

CPDLC is a system that allows text-based messages between air traffic controllers and pilots via data link instead of relying on radio voice. The best choice captures both parts of the acronym and its purpose: Controller Pilot Data Link, described as an alternative to voice communications. This reflects how CPDLC provides a separate, data-driven channel for clearances, requests, and reports, reducing voice congestion and enhancing efficiency. The other options use incorrect terms or place emphasis in ways that don’t match the actual naming or function, such as using Central instead of Controller, implying only “Data Link” without the communications aspect, or rearranging the words.
