Which term designates a two-way communication link between a JetBlue flight and JetBlue's main ground facilities?

• A. AO
• B. ATC
• C. ACARS
• D. AED

Answer: (C)

ACARS, which stands for Aircraft Communications Addressing and Reporting System, is the two-way data link that connects an airplane with the airline’s ground operations. It lets the crew exchange messages and data with JetBlue’s dispatch, maintenance, and operations centers—sending flight status, maintenance reports, weather updates, and receiving instructions or changes. That direct link to the airline’s ground facilities is exactly what the question describes.

The other options don’t fit this specific link. AO isn’t the standard term for airline-ground data communication. ATC, or Air Traffic Control, handles communications between aircraft and air traffic control centers, not with the airline’s own ground operations. AED isn’t related to flight data or airline-ground messaging at all.
