The Aeronautical Chart and Publication Control (ACPC) is a United States government agency responsible for coordinating and standardizing aeronautical charts and publications. The ACPC operates under the National Geospatial-Intelligence Agency (NGA) and works closely with the Federal Aviation Administration (FAA) to ensure the accuracy, consistency, and standardization of aeronautical information.

The primary functions of the ACPC include:

1. Chart and publication control: The ACPC reviews, validates, and approves aeronautical charts and publications to ensure they meet established standards and criteria.
2. Standardization: The agency develops and maintains standards for aeronautical charting and publication, ensuring that all charts and publications are consistent and accurate.
3. Coordination: The ACPC coordinates with various government agencies, including the FAA, NGA, and the Department of Defense, to ensure that aeronautical information is consistent and up-to-date.
4. Data management: The agency manages and maintains a comprehensive database of aeronautical information, which is used to produce charts, publications, and other products.

The ACPC plays a critical role in ensuring the safety and efficiency of air travel by providing accurate and standardized aeronautical information to pilots, air traffic controllers, and other aviation stakeholders.
