What does ATIS stand for in aviation?

ATIS stands for Automatic Terminal Information Service. This system is crucial in aviation as it provides pilots with essential information regarding airport conditions, such as weather updates, runway availability, and any pertinent notices or changes that may affect their approach and landing at airports. The use of the term "Automatic" in ATIS indicates that this information is broadcast automatically at regular intervals, allowing pilots to receive the latest data without having to request it from air traffic controllers directly. By doing so, it helps to ensure efficient communication and reduces the workload on controllers, thereby enhancing safety and operational efficiency at busy airports.
