How frequently are AIRMETs issued?

• A. Every hour
• B. Every 3 hours
• C. Every 6 hours
• D. Every 12 hours

Answer: (C)

AIRMETs, which stand for Airmen's Meteorological Information, are generally issued every 6 hours. This schedule allows pilots to receive timely updates on significant weather changes that could affect flight operations, such as turbulence, icing, and widespread areas of restricted visibility. The 6-hour interval ensures that pilots have access to current information, which is crucial for flight planning and safety. While some weather products, such as METARs (which provide hourly weather reports), are updated more frequently, AIRMETs are tailored for broader aviation needs and less frequent updates are sufficient to capture the overall significant weather patterns affecting en-route and terminal areas.
