What is ACARS primarily used for?

• A. Weather radar transmission
• B. Text messaging between pilots and dispatchers
• C. Air traffic control routing
• D. Voice communication

Answer: (B)

ACARS is a digital data-link system that transmits short text messages between an aircraft and ground stations. Its primary use is text messaging between pilots and dispatchers, enabling quick operational communications such as flight plan updates, weather data (in text form), maintenance notices, and fuel or weight changes without relying on voice radio. It does not transmit radar imagery from the weather radar, and voice communication remains separate from ACARS. While some data-link channels exist for ATC communications, the everyday function of ACARS is airline–ground messaging, not controlling routing.
