Aeronautical Information Services/Management (ICAO 021) involves the management and dissemination of aeronautical information necessary for the safety, regularity, and efficiency of air navigation. This includes the collection, processing, and distribution of data related to flight operations, air traffic, and navigation aids. The services ensure that pilots, air traffic controllers, and other aviation stakeholders have access to up-to-date information essential for their operations. Key components include aeronautical charts, NOTAMs (Notices to Airmen), and other critical information that support safe flight operations within controlled airspace. Effective management of these services is crucial for maintaining safety standards and enhancing the overall efficiency of air traffic management.
