FOREWORD

In October 1945, the Rules of the Air and Air Traffic Control (RAC) Division at its first session made recommendations for Standards, Practices and Procedures for Air Traffic Control. These were reviewed by the then Air Navigation Committee and approved by the Council on 25 February 1946. They were published as "Recommendations for Standards, Practices and Procedures - Air Trafic Control" in the second part of Doc 2010, published in February 1946.

The RAC Division, at its second session in December 1946 - January 1947, reviewed Doc 2010 and proposed Standards and Recommended Practices for Air Traffic Control. It did not appear possible, however, to finalize those Standards prior to basic principles being established by the RAC Division for the organization of the relevant services.

These were established by the RAC Division at its third session in April - May 1948 and a draft Annex was thereafter submitted to States. This was adopted by the Council on 18 May 1950, pursuant to Article 37 of the Convention on International Civil Aviation (Chicago, 1944), and designated as Annex 11 to the Convention with the title "international Standards and Recommended Practices - Air Trafic Services". It became effective on 1 October 1950. This new title - Air Traffic Services - was preferred to the title Air Traffic Control, in order to make it clear that air traffic control service was a part of the services covered by Annex 11, together with flight information service and alerting service.

Table A shows the origin of subsequent amendments, together with a list of the principal subjects involved and the dates on which the Annex and the amendments were adopted by the Council, when they became effective and when they became applicable.
