What type of information does the Chart Supplement U.S. provide?

The Chart Supplement U.S. serves as a critical resource for pilots, offering comprehensive information on airports, heliports, and seaplane bases across the United States. This publication includes essential details such as runway dimensions, lighting, communication frequencies, navigational aids, and other operational information necessary for safe flight operations.

In contrast, weather forecasts for individual airports are provided by the National Weather Service and other meteorological sources, while navigation charts are specifically published in different formats, such as sectional charts, which depict the layout of airspace but do not contain the extensive airport information found in the Chart Supplement. Lastly, updates on air traffic laws and regulations are typically available through supplemental sources like the Federal Aviation Administration (FAA) website or related publications, not within the Chart Supplement itself. This distinction highlights why the comprehensive nature of the Chart Supplement specific to airports and related facilities makes it an invaluable tool for pilots.
