Reveal Answer
Correct Answer:
Controller-Pilot Data Link Communications
Explanation:
CPDLC stands for Controller-Pilot Data Link Communications. This is a data link system that lets the controller and the pilot exchange messages via text rather than voice radio. It covers clearances, route changes, altitude and speed instructions, holds, and other routine instructions using predefined phrases and, where needed, free text. The benefit is reduced radio chatter, improved clarity, and more efficient operations, especially where voice coverage is limited, such as oceanic or remote airspace. On modern aircraft like the 787, CPDLC is part of the ACARS data link suite and supports the FANS-1/A capabilities, enabling timely, auditable communications between ATC and the flight crew. The other options don’t reflect the correct acronym or the system’s purpose.
