How frequently are Aeronautical Information Circulars (AICs) published?

Aeronautical Information Circulars (AICs) are published on a monthly basis, which means they are regularly issued to provide important information to pilots and other aviation personnel. These documents serve as a means to disseminate information of an operational or safety-related nature, which may not necessarily be included in formal NOTAMs (Notices to Airmen) or other aviation publications.

The monthly publication schedule allows for timely updates and ensures that pilots have access to relevant information on a routine basis, helping them to stay informed about changes in regulations, procedures, or significant issues affecting air navigation. This frequency strikes a balance between providing sufficient updates without overwhelming users with information, as might occur if they were distributed weekly. Additionally, it is different from less frequent releases, such as quarterly or annually, which may not meet the dynamic needs of the aviation community.
