What is the primary function of ATIS?

The primary function of Automatic Terminal Information Service (ATIS) is to transmit critical information related to airport operations, specifically for take-off and landing procedures. ATIS broadcasts essential data that pilots need, such as weather conditions, active runways, and other pertinent operational information, facilitating safe and efficient aircraft operations during arrival and departure.

This information is crucial for pilots as it helps them prepare for their approach or departure, ensuring they are aware of current situations at the airport. By providing this data automatically and repetitively, ATIS allows pilots to receive vital updates without having to tie up radio frequencies unnecessarily, thus promoting efficient communication in busy air traffic environments. This capability helps maintain safety and situational awareness for pilots as they navigate through busy terminal airspace.
