International Cooperation


We participate in the development of European airspace through the cooperation in multiple organizations and associations.


The Single European Sky implementation demands close cooperation at the European level. Read further to find out in which international organizations, associations and cooperations we participate:

  • INEA Projects
  • FAB CE
  • Gate One
  • ICAO 
  • Eurocontrol
  • CANSO.


SESAR is a research program in the field of air traffic management in Europe, i.e. the technological part of the Single European Sky initiative.

To manage the development of SESAR, the European Union founded the SESAR Joint Undertaking in 2007 as a public-private partnership of the European Commission, Eurocontrol, and the aviation sector, including air navigation service providers.

By the end of 2021, SESAR 3 Joint Undertaking was officially launched, thus marking a new chapter in the modernization of European air traffic management. SESAR 3 JU supersedes its predecessor SESAR JU, assumes all its tasks and responsibilities encompassed by the SESAR 2020 program and launches the new SESAR 3 program. In a joint effort with other COOPANS members, CCL will actively participate in the activities of SESAR 3 JU as one of the founding members.

To implement joint projects aimed at improving the efficiency of the European air traffic management system, the European Commission established the SESAR Deployment Manager function (SESAR Deployment Manager) in 2014, bringing together airlines, airport operators, and air navigation service providers. 

INEA Projects

The Innovation and Networks Executive Agency (INEA), managing infrastructure and research programs in the fields of transport, energy and telecommunications, is an important partner in the modernization and development of our services. 


The Functional Airspace Block Central Europe (FAB CE) is a joint initiative of Croatia, Austria, Bosnia and Herzegovina, Hungary, the Czech Republic, Slovakia and their air navigation service providers. The establishment of FABs is an obligation arising from an interstate agreement under the Single European Sky regulation.

The aim of this regional association is to increase air traffic safety, reduce delays and costs for airspace users and protect the environment.


COOPANS is an international partnership of air navigation service providers from Croatia (Croatia Control), Ireland (IAA), Sweden (LFV), Denmark (Naviair), Austria (Austro Control) and Portugal (NAV Portugal).

With Thales as the chosen supplier, COOPANS members implemented the same software in 7 ACC centers (Zagreb, Vienna, Copenhagen, Stockholm, Malmö, Dublin and Shannon).

The cooperation was extended in 2015 when COOPANS became an alliance which, in addition to the technical and operational cooperation, includes a joint approach and participation in SESAR 2020, SESAR DM and the A6 Alliance in which it cooperates with the largest air navigation service providers in Europe.

As a leading example of industrial partnership in Europe, the COOPANS Alliance was awarded the Single European Sky Award 2016 by the European Commission for the successful implementation of the Single European Sky.

Gate One

Gate One is a cooperation of 13 air navigation service providers grouped into 3 functional airspace blocks (FAB CE, Baltic FAB, Danube FAB) and 2 non-EU FIRs (Belgrade and Skopje). Its purpose is promoting efficient European air traffic management, strengthening the cooperation of service providers and facilitating the stronger and better coordinated representation of the countries in European decision-making processes.


The International Civil Aviation Organization (ICAO) is a specialized agency of the United Nations which sets standards and recommended practices to enhance aviation safety. ICAO develops the principles of safety, capacity and efficency of air navigation and promotes air traffic planning and development.


Eurocontrol is the European Organization for the Safety of Air Navigation, working to harmonize and develop air navigation services in the member states. It performs tasks within the Single European Sky legislative framework and provides technical support to the European Commission in the field of regulatory measures. It also acts as the network manager for the air traffic management network functions and collects the charges paid by airlines for using the air navigation services. Eurocontrol operates a center in Maastricht from which it controls the upper airspace over Belgium, Luxembourg, the Netherlands and Western Germany.


CANSO is an association of civil air navigation service providers, established to create value for its members, to represent the interests of the industry and foster industry development globally and regionally. Croatia Control operates within CANSO Europe and actively participates in the work of various committees.
