FOREWORD
Historical background
Standards and Recommended Practices for Aeronautical
Telecommunications were first adopted by the Council on
30 May 1949 pursuant to the provisions of Article 37 of the
Convention on International Civil Aviation (Chicago 1944)
and designated as Annex 10 to the Convention. They became
effective on 1 March 1950. The Standards and Recommended
Practices were based on recommendations of the Communications
Division at its Third Session in January 1949.
Up to and including the Seventh Edition, Annex 10 was
published in one volume containing four parts together with
associated attachments: Part I - Equipment and Systems,
Part11 - Radio Frequencies, Part III - Procedures, and
Part IV - Codes and Abbreviations.
By Amendment 42, Part IV was deleted from the Annex;
the codes and abbreviations contained in that part were
transferred to a new document, Doc 8400.
As a result of the adoption of Amendment 44 on
31 May 1965, the Seventh Edition of Annex 10 was replaced
by two volumes: Volume I (First Edition) containing Part I -
