What is the purpose of the ATIS service?

The purpose of the ATIS (Automatic Terminal Information Service) is primarily to provide continuous weather updates to pilots, along with other essential information relevant to the approach and landing phases at an airport. ATIS broadcasts real-time data, including current weather conditions, visibility, wind direction and speed, runway in use, and any pertinent notices or changes affecting operations.

By providing this information consistently, ATIS helps pilots prepare for their approach and landing, ensuring they have the necessary data to make informed decisions. The broadcast is typically updated hourly or as conditions change and is crucial for enhancing situational awareness, thereby improving safety and operational efficiency during high-traffic airport operations.

While the other options may involve important aviation functions, they do not accurately reflect the specific and primary role of ATIS. For instance, tracking aircraft movements is typically managed by air traffic control, while navigation assistance is offered through different means, such as navigational aids and instruments. Ground operations are facilitated through distinct services and communications that do not fall under the scope of ATIS.
