What is AIRAC?
AIRAC stands for Aeronautical Information Regulation And Control. It is a system that defines a series of common dates and an associated standard aeronautical information publication procedure for States so that, for both efficiency and safety, pilots, dispatchers, air traffic controllers, air traffic flow managers, flight management systems and aeronautical charts all have the same information working from the same information base.
AIRAC is based on the International Civil Aviation Organization (ICAO) Annex 15 on Aeronautical Information Services (AIS), which specifies that important changes in aeronautical information should be maintained by a predetermined production schedule. The schedule of internationally agreed AIRAC effective dates for the years 2020 to 2029 is given in this table:

The AIRAC system covers all aeronautical information objects (AIOs) that are essential for flight operations, such as airports, runways, taxiways, aprons, navaids, airways, waypoints, airspace boundaries, air traffic services (ATS) routes, instrument flight procedures (IFPs), minimum altitudes, obstacles, etc. These AIOs are subject to changes due to various reasons, such as construction, maintenance, safety, efficiency, environmental impact, etc. The AIRAC system ensures that these changes are published and distributed in a timely and coordinated manner to all users of aeronautical information.How does AIRAC work?
The AIRAC system works by dividing the year into 13 cycles of 28 days each. Each cycle has a publication date and an effective date. The publication date is the date when the aeronautical information providers (AIPs), such as States, regions, or organizations, publish the changes in their aeronautical information products (AIPs), such as charts, manuals, databases, etc. The effective date is the date when the changes become effective and must be used by the users of aeronautical information.

The publication date is always at least 42 days before the effective date. This allows enough time for the users to receive, process, and implement the changes in their systems and operations. The effective date is always on a Thursday and coincides with the first day of the International NOTAM (Notice to Airmen) Series. A NOTAM is a message that contains information concerning the establishment, condition or change in any aeronautical facility, service, procedure or hazard. NOTAMs are used to notify users of any changes that are not included in the AIRAC cycle or that occur between two AIRAC cycles.
The AIRAC cycle number consists of four digits: the first two digits indicate the year and the last two digits indicate the cycle within that year. For example, AIRAC cycle 2106 means the sixth cycle of the year 2021. The AIRAC cycle number is used to identify the version of the aeronautical information products that contain the changes for that cycle. For example, if you see a chart with the label "AIRAC AMDT 2106", it means that the chart has been amended with the changes from AIRAC cycle 2106.What are the advantages of using AIRAC?
The main advantage of using AIRAC is that it enhances the safety and efficiency of flight operations by providing updated and accurate navigation data.
