What is the primary communication for flight status and progress?

• A. ACARS
• B. ATC
• C. VHF
• D. HF

Answer: (A)

ACARS is the digital data-link that handles flight status and progress reporting between the airplane and ground systems. It automates and standardizes the flow of information such as position, altitude, speed, fuel, ETA, weather updates, and maintenance messages, so operations can track how the flight is progressing without relying on voice radio for every update. It transmits these status reports via VHF data-link on shorter routes and via satellite or HF on longer, oceanic legs, ensuring continuous visibility of the flight’s status. While ATC uses voice channels for instructions and separation, and VHF/HF are radio bands for voice communications, ACARS provides the dedicated data channel specifically for flight status and progress, making it the primary method.
