What type of information is found in a green AIC?

A green Aeronautical Information Circular (AIC) primarily provides information related to maps and charts that are essential for pilots. This type of AIC serves as a notification for changes, updates, or details about navigational charts, aerodromes, or airspace structure that pilots need to be aware of to ensure safe and efficient flight operations. Understanding the specifics within a green AIC is critical as it aids pilots in planning their routes and understanding geographical features.

In the context of the other options, air traffic regulations are usually found in air traffic control publications and regulations rather than a green AIC. Weather notifications are typically disseminated through METARs, TAFs, or dedicated weather AICs. Flight operation updates could be part of a different AIC color specific to operational procedures or safety notices. Overall, a green AIC's focus is dedicated to enhancing pilots' navigational awareness through maps and related information.
