61 years ago, Standards and Recommended Practices for Aeronautical Information Services (AIS) were first adopted by the Council on 15 May 1953, pursuant to the provisions of Article 37 of the Convention on International Civil Aviation (Chicago 1944), and were designated as Annex 15 to the Convention.

This is a very important milestone since before the Annex 15 was adopted the AIS requirements had undergone the continuous changes.

The first requirements were developed by the Air Navigation Committee as a result of recommendations of Regional Air Navigation Meetings and were published by authority of the Council as Procedures for International Notices to Airmen (PANS-NOTAM, PICAO Doc 2713) in January 1947.

In 1949, the Special NOTAM Meeting proposed amendments to these procedures which were later issued as Procedures for Air Navigation Services (PANS-AIS, Doc 7106) and which became applicable on 1 August 1951.

In 1952, the PANS-AIS were reviewed by the First Session of the Aeronautical Information Services Division which recommended the adoption of Standards and Recommended Practices. Following consideration by all Contracting States, these recommendations were reviewed by the Air Navigation Commission and the first set of Standards and Recommended Practices was adopted by the Council on 15 May 1953.

For this reason, a number of States celebrate 15^th May as an AIS Day.
