The International Advisory Group Air Navigation Services (ANSA) offers aviation research institutions, libraries, archives, museums, historians, aviators, students, air navigation concerned persons and aviation journalists information, publications and support on the subject of air navigation and air traffic control. ANSA is a non-profit group of aviation professionals under swiss law with members of the aviation sector in a dozen countries.

ANSA was founded in 1967 in Germany under the former name of 'Evaluation Group Air Navigation Services - Europe'. Among its members are civil and military pilots, air traffic controllers, dispatchers, telecommunication operators, engineers, instructors, experts on air traffic control and an air safety investigator. All are bearers of corresponding official licences.

ANSA knows the international and national rules, regulations and procedures of the ATC system. The improvement of flight safety in general is our objective, as is the reduction of the risk of accidents in the air navigation system as well as the broadening of knowledge on the functioning of the ATC system and its weaknesses.

An additional aim lies in the explanation of the historical development of the ATC system in operations and engineering over the many decades. For this purpose two separate internet platforms exist: Digitale Luftfahrt-Bibliothek at (German language) and Digital Aviation Library at (English language). The Digital Aviation Library offers a multitude of normally not available or forgotten documents for historians, experts and students under the headings of bibliographies, general aviation history, historical aviation documents and aviation maps.

ANSA is represented by its founder and president, Mr. Frank W. Fischer, an ATM expert accredited by the European Union. The corporation is based at L├╝terkofen in the cantone of Solothurn, Switzerland. The office is located at Kreuzlingen in the cantone of Thurgau, Switzerland.
