The primary purpose of the Automatic Terminal Information Service (ATIS) is to provide what to pilots?

The Automatic Terminal Information Service (ATIS) is designed primarily to provide pilots with vital information related to weather conditions, active runway information, and other pertinent data that can affect flight operations at an airport. This information typically includes weather reports such as visibility, wind direction and speed, altimeter settings, and any other significant changes that could impact landing and takeoff, as well as ongoing traffic delays. By continuously broadcasting this information, ATIS streamlines the communication process for air traffic control and enhances situational awareness for pilots.

In contrast, options such as flight training updates, fuel efficiency calculations, and maintenance reports do not align with the core function of ATIS, which focuses specifically on delivering critical operational information to pilots flying in and out of airports.
