The Geographical analysis of the Republic of Croatia’s airspace is based on the geo-position at the border between the Central part and Southeast part of Europe, which provides a strategic location for connecting the Middle East and Asia with Europe. This structure of airspace is in accordance with EU legislation and ICAO standards and consists of the single flight information region that follows state borders, the control area classified as C, D, and G areas and the control zone around all 9 international airports. The Republic of Croatia’s airspace has a small number of restrictions mostly due to military exercises. NATO values the Republic of Croatia’s geographical position because it offers a perfect location because of the safe distance for the logistics and all operational activities needed for military operations. International importance of airspace is defined in ways of development within a Single European Sky, implementation of a free route airspace concept, and a flexible use of airspace with collaboration inside the functional block of Central Europe’s airspace. These initiatives assure the highest safety standards and maximum potential and capacity of the Republic of Croatia’s airspace.
