ATIS
Automatic Terminal Information Service
The Automatic Terminal Information Service (ATIS) is a continuous broadcast of recorded non-control information at airports. It provides arriving and departing crews with current airport conditions without requiring them to contact a controller for routine information. A standard ATIS message includes the current altimeter setting, active runway(s), wind direction and speed, visibility, cloud cover, temperature and dew point, NOTAM highlights affecting operations, and any special notices such as taxiway closures or equipment outages. ATIS broadcasts are identified by a sequential phonetic alphabet code (Alpha, Bravo, Charlie, and so on), which cycles back to Alpha after each update.
Pilots are expected to obtain the current ATIS before initial contact with ATC at the destination and to include the ATIS identifier in their initial call - for example, “information Bravo received.” This confirms to the controller that the crew has current airport information and eliminates the need for the controller to relay it. When the ATIS is updated due to a significant change (such as a new altimeter, runway change, or weather shift), a new letter is assigned and crews should obtain the updated information before landing. At some airports, separate D-ATIS (digital ATIS) is available via ACARS datalink.
