CPDLC usage in oceanic/remote and busy terminal areas reduces what workload?

• A. Weather briefing workload.
• B. Voice workload by providing text-based messages between controller and pilot to convey clearances, route changes, and instructions, reducing voice workload, especially oceanic/remote and busy terminal areas.
• C. Ground operations workload.
• D. Pilot fatigue.

Answer: (B)

CPDLC replaces many spoken exchanges with text messages between the controller and the pilot. In oceanic/remote airspace and busy terminal areas, voice channels can get crowded, transmissions may be misheard, and lengthy exchanges can require repeats. Text-based, structured messages for clearances, route changes, and instructions are quicker and clearer, reducing the time and effort spent on radio communications. This lowers the voice workload for both controllers and pilots and helps keep traffic flowing more smoothly. Weather briefings, ground operations, and fatigue are not directly addressed by CPDLC in the same way, so they don’t benefit from this same reduction in voice communications.
