Which function does the Automatic Terminal Information Service (ATIS) provide?

The Automatic Terminal Information Service (ATIS) primarily serves the function of broadcasting recorded aeronautical information. This includes essential data such as weather conditions, active runways, and any notable information for arriving and departing aircraft, making it a critical resource for pilots at busy airports. By providing this information continuously and automatically, ATIS allows pilots to receive the latest updates without taking up air traffic control time, which helps streamline operations and maintain safety.

In this context, the other options do not accurately define the role of ATIS. Real-time traffic updates are typically handled by air traffic control rather than being a function of ATIS. While accuracy of local weather is included in the ATIS broadcast, it does not offer weather forecasts. Similarly, scheduling flight clearances is a function of air traffic controllers rather than the ATIS system.
