When is new ATIS released?

• A. Immediately after sunrise
• B. Only when a weather phenomenon is observed
• C. When new authorized weather information is received
• D. On a fixed schedule every hour

Answer: (C)

New ATIS releases whenever new authorized weather information is received. ATIS is a continuously updated broadcast of airport weather and other essential information, and it changes when the weather data has been officially issued or updated by the weather service or airport operations. This could be a new METAR/TAF, a change in wind, visibility, cloud cover, precipitation, runway in use, or other critical notices that pilots need to know. The update ensures pilots have the current information before flight. It isn’t tied to sunrise, nor tied to a fixed hourly schedule, and it isn’t sent only when a weather phenomenon is observed; it’s triggered by the arrival of new, authorized data. Pilots check the current ATIS information identifier to confirm they have the latest broadcast.
