What is the purpose of an ATIS broadcast?

The purpose of an ATIS (Automatic Terminal Information Service) broadcast is primarily to reduce controller workload and relieve frequency congestion. ATIS provides pilots with essential information such as weather conditions, active runways, and any relevant notices or changes at the airport without requiring air traffic controllers to continuously repeat this information. By broadcasting this data on a continuous loop, pilots can listen to the ATIS frequency before contacting air traffic control, allowing them to come prepared with the necessary information. This streamlines communication and allows controllers to focus on coordinating air traffic instead of continuously providing updates for each incoming pilot.

In contrast, options that suggest ATIS provides flight directions, monitors emergencies, or gives real-time updates on flight paths are less accurate. ATIS does not give specific navigational instructions but rather ensures pilots have a solid understanding of the current operational environment at an airport, thus facilitating safer and more efficient operations.
