Aeronautical information regulation and control (AIRAC) dates

Aeronautical information regulation and control (AIRAC) defines a series of common dates and an associated standard aeronautical information publication procedure for States.

In short it defines that in all instances, information provided under the AIRAC system shall be distributed by the AIS unit at least 42 days in advance of the effective date with the objective of reaching recipients at least 28 days in advance of the effective date. Whenever major changes are planned and where additional notice is desirable and practicable, a publication date of at least 56 days in advance of the effective date should be used.

To this end, we make a list of AIRAC dates available for download.
