ATIS should be updated when which event occurs?

• A. upon receipt of any new official weather
• B. pilot requests
• C. airport management schedules
• D. every 15 minutes

Answer: (A)

ATIS is updated whenever new official weather information becomes available. This ensures pilots receive the most current conditions (METAR/TAF changes, wind, visibility, altimeter, etc.) before taxi, takeoff, or landing, reducing the need for pilots to ask for weather separately and helping maintain safe operations. Pilot requests don’t trigger an update because ATIS should reflect official weather changes as they occur. Airport management schedules or routine timing don’t automatically drive updates either; content is driven by actual weather changes and other essential information, not a fixed clock. Updates on a set interval (like every 15 minutes) aren’t reliable because weather can change more quickly or slowly than a timer.
