The book series Die Entwicklung der Flugsicherung in Deutschland has been published in German. This is the first of two translated books. This documentation on the development of air traffic control in West Germany after 1945 explains the continuation of the further development of the establishment of military tactical air traffic control units, which began under the military governments of the victorious powers and the subsequent Allied occupation forces in Germany. This transport service of the first decade after the end of the war forms the cradle of modern European air traffic control as the main component of the entire air traffic control system. It ended with the partial restoration of air sovereignty in West Germany (BRD) in 1955 and the end of supervision of the restored Federal Air Traffic Control Administration by HICOM's Allied Civil Aviation Board - CAB in mid-1956.

This document provides a comprehensive historical account of the International Advisory Group - Air Navigation Services (ANSA) and shows the achievements, organizational changes, and contributions to the aviation industry. Established in 1967 by German air traffic controllers from the Rhein Control upper airspace ATC center, ANSA is a non-profit organization dedicated to improving air traffic control systems and procedures. Initially formed to support German air navigation authorities and EUROCONTROL, the group expanded its membership to include experts from over 20 countries. In 1985, ANSA moved its legal seat to Switzerland, continuing its mission to enhance flight safety and modernize ATC systems.

The documentation by Frank W. Fischer deals with the development of the German air traffic control centre for the upper airspace of southern Germany RHEIN UAC with the radio call sign RHEIN CONTROL, which was operated on the Erbeskopf in the Hunsrück from 1957 to 1968 and from 1968 to 1977 at Frankfurt am Main Airport. The Rhine UAC air traffic control centre was known to all airlines and military units flying over Germany's upper airspace in the post-war period. In addition, this air traffic control centre had already been confronted with traffic problems since the 1950s, which other air traffic control centres and air traffic control service providers in Europe only had to contend with many years later. Rhein UAC was the cradle of a variety of methods and operational procedures for air traffic control that were unknown to other air traffic services at the time, and it was the time of the Cold War. Germany was divided and the air forces of the occupying powers overcrowded the airspace with almost 2,000 combat aircraft during the day and at night. Military air operations that the population had never heard about. The Cold War - the confrontation between East and West - also took place far above the clouds in the upper airspace. But many aspects of civil and military air traffic control had not yet been regulated. Some things had not even been invented yet. In particular, the mixture of civil and military operating and control procedures was unique. The uniqueness consisted of the combination of joint operations, personnel and air traffic control procedures. Three personnel contingents, namely the US Air Force, the Federal Air Traffic Control Centre and the German Armed Forces, managed flights of all traffic categories. This also included all military training and special flights as well as the target flights of major NATO air manoeuvres.
