Aircraft Communications Addressing and Reporting System

The Aircraft Communications Addressing and Reporting System (ACARS) is a digital messaging system used by aircraft and ground stations to exchange vital information. It allows pilots to send and receive messages related to flight status, weather updates, technical issues, and other operational details efficiently and accurately. Using secure radio or satellite links, ACARS helps airlines improve communication, safety, and efficiency by automating routine reports and alerts, reducing the need for voice communication, and ensuring timely sharing of critical information during flights.
