Which system is abbreviated as ATIS?

The Automatic Terminal Information System (ATIS) is a continuous broadcast of recorded aeronautical information for arriving and departing aircraft. This system provides essential data such as weather information, active runways, and any notices to airmen (NOTAMs) relevant to the operation of aircraft at an airport. ATIS is designed to improve the efficiency of air traffic control communications by allowing pilots to receive important information before contacting air traffic control. This streamlines communication, as multiple aircraft can receive the same information simultaneously, helping to reduce congestion and potential misunderstandings during busy air traffic periods.

The other options do not accurately represent the established term within the aviation industry, rendering them incorrect. Understanding the function and purpose of ATIS is crucial for pilots and aircrew operating in busy terminal airspaces.
