More about Automatic Terminal Information Service
ATIS commonly includes weather, runway information and other relevant local conditions. A letter identifies the current edition.
Listening to ATIS helps reduce repeated radio exchanges. It does not replace a required clearance, and crews must use the current information rather than assume an earlier edition remains valid.
