How often are Sectional Aeronautical Charts published?

Sectional Aeronautical Charts are published every six months to ensure that the information is current and accurate for pilots and air traffic controllers. This regular updating cycle accounts for changes in aeronautical information such as airspace changes, new navigational aids, and updates to obstacles, which are critical for safe navigation. The various elements on the chart, including terrain features, airports, and airspace designations, can change, and a six-month publication interval allows for timely updates while providing sufficient time for dissemination and utilization by pilots. This schedule is standardized to promote safety and operational efficiency in aviation.
