Aeronautical Information Regulation and Control (AIRAC)

AIRAC, or Aeronautical Information Regulation and Control, is a system used in aviation to manage the timely and consistent update of essential information for safe and efficient aircraft operations. It standardizes how changes to charts, procedures, and regulations are issued, typically on a cycle of every 28 days. This ensures pilots, airlines, and air traffic control have accurate, up-to-date data, reducing risks caused by outdated information. AIRAC systems promote coordination across the aviation community, enabling smooth planning and navigation while maintaining high safety standards.
