Which component interfaces with data link to provide digital communications between controllers and pilots?

• A. Radar display
• B. Weather radar
• C. Analog voice communication
• D. CPDLC/data link

Answer: (D)

Digital communications between controllers and pilots are handled by CPDLC via the data link. This system provides text-based messaging over a data link network, enabling ground-to-cight communication for clearances, route changes, and other instructions, using VHF or satellite links. It replaces or supplements voice with a recordable, reliable digital channel. Radar display is for tracking and presenting aircraft positions, not for sending cockpit messages. Weather radar shows weather patterns to controllers and pilots, not the message exchange channel. Analog voice communication uses traditional voice channels for real-time spoken exchanges and does not facilitate digital textual data link communications.
