AIRAC, For Part 2 of RTR (A) | AIRAC 1


Definition of AIRAC

 

You may get a question as to explain AIRAC (Aeronautical Information Regulation and Control) in Part 2 of RTR (A) exam.

This is what all there is to know about Aeronautical Information Regulation and Control so as to answer the examiner satisfactorily

AIRAC

AIRAC is a system established by the ICAO Annex 15 to ensure that changes to aeronautical information are made in a consistent manner — the needed data (paper or electronic) is released prior to the effective date of change, which has been predetermined to occur at an interval of 28 days (each 28-day period is deemed a “cycle”). Thus all airmen will have a consistent set of data world-wide. Urgent or temporary changes which not part of the Aeronautical Information Regulation and Control cycle of dates are handled with the NOTAM system.

The types of aeronautical information to be included in Aeronautical Information Regulation and Control are listed in Annex 15 Appendix 4.

Since many of the changes to facilities, services and procedures can be anticipated and become effective in accordance with a predetermined schedule of effective dates, ICAO recommends use of a regulated system (Aeronautical Information Regulation and Control) designed to ensure that:

a) Information concerning circumstances listed in para 6.3 of appendix 4 will be issued as AIP Supplements. These supplements must be identified by the acronym “AIRAC Aeronautical Information Regulation and Control” and distributed at least 42 days in advance of the effective date with the objective of reaching recipients at least 28 days in advance of the same date.

b) The AIRAC effective date must be in accordance with the predetermined internationally agreed schedule of effective dates based on an interval of 28 days including 1st September, 2005

c) Information so notified must not be changed further for at least another 28 days after the indicated effective date, unless the circumstances notified is of temporary nature and would not persist for the full period.

There are three significant dates associated with the AIRAC system:

a) The effective date

b) The publication date; and

c) The latest date for raw material to reach the AIS.

 

There must be an interval of 42 days between the publication/distribution date and the effective date. This allows for a period of upto 14 days distribution time, by the most expeditious means, in order for recipients to receive the information at least 28 days in advance of the effective date. In cases where major changes are planned and more advance notice is desirable and practicable, a distribution date of 56 days, or even longer, in advance of the effective date should be used.

 

When the AIS Section does not receive any information for publication on the next scheduled Aeronautical Information Regulation and Control effective date, a NIL Notification shall be originated and distributed by NOTAM at least one cycle (28 days or more) before the AIRAC effective date concerned.
