Croatia Airlines - ADS - B OUT implementation

ADS - B OUT implementation


Croatia Airlines, co-financed by the European Commission under the Connecting Europe Facility (CEF) program, has fulfilled the EASA mandate to use ADS - B OUT (Automatic Dependent Surveillance - Broadcast Out) functions in the European airspace.

The implementation of the equipment that meets the ADS - B OUT performance requirements was completed on all aircraft in our Dash 8 and Airbus fleets on 19th of March 2020.

In accordance with the worldwide deadline for all aircraft to be equipped with the ADS-B OUT function, which provides more precise control of aircraft by flight control, Croatia Airlines has started upgrading its Dash 8 and Airbus fleets on time to reach the EASA mandate date. The ADS - B Out upgrade project started in mid-2018 and is co-financed by the European Commission under the Connecting Europe Facility (CEF) program, with 20% of the total cost. Completion of the project is planned in the first half of 2020.

For the European aerospace area, there are already about 800 ground stations installed for the ADS-B function that are a part of the Single European Sky ATM Research (SESAR) project. The Single European Sky Project (SESAR) was launched in 2004 and its role is to define, develop and implement what is needed to increase the efficiency of Air Traffic Management (ATM) and build a European intelligent air traffic system.

Upgrading Dash 8 and Airbus aircraft ADS-B OUT is in line with the cohesion policy and supports the infrastructure projects of the European Air Traffic Management System (ATM) within CEF.

New technologies, such as ADS-B, will find their place in the Croatian air traffic control system in the near future. Upgrading ADS - B OUT functionality on Croatia Airlines aircraft could accelerate the installation of new terrestrial ADS - B stations in Croatia and thus further develop the European air traffic.

As a part of the European ATM Master Plan, the implementation of ADS-B OUT on the DASH 8 and AIRBUS fleet will have direct and measurable benefits for the European ATM and aviation in Europe. 

Croatia Airlines expects to benefit from all the ambitions of the SESAR project:

  • ANS productivity: reduced En-route and TMA costs per flight
  • Operational efficiency for airspace users: reduced fuel burn and flight time
  • Capacity: reduced delays, increased network throughput and throughput at congested airports
  • Environment: reduced CO 2 emissions
  • Safety and security: high standards
