As of January 27, 2022, Croatia Control (CCL) has been certified for providing the Flight Procedure Design (FPD) service in line with the EU law, which makes it richer for a new service and places it among reputable air navigation service providers.
The certification, conducted by the Croatian Civil Aviation Agency, creates additional opportunities for CCL, in the sense of broadening the scope of its users of this service, both in Croatia and abroad.
Designing flight procedures according to the defined criteria enables safe obstacle clearance for normal and regular instrument flights of aircraft.
The service encompasses the design, documentation, validation, and maintenance of conventional and PBN procedures in the phases of standard instrument departures and arrivals, instrument approach, circling approach, en route flying, and future PinS procedures for helicopters.
The process of providing the service includes the production of aeronautical charts, definition of polygons of minimum altitudes for radar vectoring, analysis of noise and exhaust emissions, analysis of the signal coverage of radio navigational aids, and analysis of the impact of areas and zones on procedures and routes.
Flight procedures are defined with regard to aircraft performance, technical characteristics of navigation systems and aerodromes, meteorology, ecology, airspace features, requirements of users, terrain, and aeronautical obstacles.
All data and aeronautical charts for the conventional and PBN procedures, for all international airports in Zagreb FIR, are published in the Aeronautical Information Publication of the Republic of Croatia.
CCL has been designing instrument flight procedures for all international airports in the Republic of Croatia for many years, and it is currently designing, amending, and maintaining around 500 conventional and PBN procedures.
