International Cooperation
Sesar Projects
CCL actively participates in the SESAR 3 JU activities alongside other COOPANS members. CCL is involved in the governance structures of the SESAR 3 JU and participates in the SESAR 3 projects including EXODUS, ISLAND, and ATC-TBO.

EXODUS is a Digital Sky Demonstrator project under the CEF 2022 call, to be implemented by the end of 2026.
EXODUS will demonstrate the concept of the virtual center and showcase business continuity scenarios in different airspaces using a new operating model based on the geographical separation of ANS and ADSP services.
The project involves the establishment of an innovation platform that reduces the risk of implementing new functionalities of the TopSky-ATC One system, where new ATM concepts will be developed and validated before the functionalities are added to TopSky-ATC One. The platform will also support the evaluation of new ATM components from other suppliers that can be integrated into COOPANS’ TopSky-ATC One system.
Besides CCL, the EXODUS participating organizations are Austro Control, Naviair, AirNav Ireland, NAV Portugal, LFV, and Eurocontrol. CCL’s share in the project amounts to EUR 11,400,000, with the EU co-financing rate of 50%.
CCL also participates in two more research and development projects co-financed under the Horizon Europe program. These projects are:
ISLAND involves industrial research aimed at the timely and efficient creation and use of airspace capacity, combined with targeted and effective requirements and/or measures.
The project team includes Eurocontrol, 10 ANSPs, 3 research establishments, and 3 companies.
CCL’s share in the project amounts to EUR 42.750, with the EU co-financing rate of 70%.
ATC-TBO is a trajectory-based air traffic control operations project.
Once a flight is in its execution phase, the trajectory may need to be changed, e.g. due to adverse weather conditions, restricted/hazardous areas, arrival procedures and the runway configuration at the destination airport. The project focuses on these flight performance challenges.
Under the overall coordination of Eurocontrol, the project team includes 14 ANSPs, 1 airspace user, 5 research establishments, and 1 university.
CCL’s share in the project amounts to EUR 280.320, with the EU co-financing rate of 70%.
