Use of funs in the world and it's implementation to the Turkish Airspace

11 ABSTRACT Master of Science Thesis USE OF FANS IN THE WORLD AND IT'S IMPLEMENTATION TO THE TURKISH AIRSPACE KADRIYE YAMAN Anadolu University Graduate School of Natural and Applied Sciences Civil Aviation Program Supervisor: Assist Prof. Dr. Hakan OKTAL 2002, 205 Pages After 1980's, significant changes have occurred in the aviation industry. In 1983, International Civil Aviation Organization-ICAO pointed at the fact that the increasing air traffic rate, which was predicted as 5% per year, could not be handled by the available systems in terms of safety, capacity and efficiency and made definitions of 21st century's communication, navigation, surveillance and air traffic management systems. FANS (also referred to as CNS/ATM) concept, just like gas turbine engines, became a revolution in the air transportation industry. Application of FANS will replace ground-based navigation systems and voice position reporting systems with satellite-based navigation systems and digital communication technologies. The system is planned to be launched in 2010. Today, study groups in ICAO Air Navigation Regions perform the studies regarding the systems with global, regional and national plans. In this study, first, necessity of FANS concept, activities regarding FANS in the world, conveniences introduced by the system and guidelines of its application will be investigated, and then the advantages provided by its application in Turkey will be discussed after making a general assessment of Air transportation in Turkey. Keywords: Future Air Navigation Systems (FANS), Communication Navigation Surveillance / Air Traffic Management (CNS/ATM), Global Navigation Satellite Systems (GNSS), Automatic Dependant Surveillance-Broadcast (ADS-B), Aeronautical Telecommunication Network (ATN).
