PRB monitoring
▪ Croatia Control registered zero minutes of average en route ATFM delay per flight during 2020, thus meeting the local breakdown value of 0.43.
▪ Delays must be considered in the context of the traffic evolution: IFR movements in 2020 were 58% below the 2019 levels in Croatia.
▪ Croatia reported 14% less ATCO FTEs by the end of 2020 than in 2019. This was due to accelerated ATCO retirement, postponed training activities, a change in paid leave dynamics and allocation of ATCOs to non-operational work.
▪ Croatia reported that the planned number of ATCOs for 2020 was calculated using the total number of ATCO licenses instead of ATCO FTEs in OPS. Thus, the PRB does not have enough information to estimate potential capacity shortfalls.
▪ The yearly total of sector opening hours in Zagreb ACC was 20,133, showing a 45.0% decrease compared to 2019.
▪ Zagreb ACC registered 14.02 IFR movements per one sector opening hour in 2020, being 23.0% below 2019 levels.
Summary of capacity performance
The Zagreb FIR experienced a traffic reduction of 58% from 2019 levels, to 301k flights. The traffic level was accommodated with negligible en route ATFM delays to airspace users.
NSA’s assessment of capacity performance
The results are in line with traffic indicators and expectations. In the pandemic year 2020 there were no challenges for LDZO [Zagreb] ACC capacities.
Monitoring process for capacity performance
Monitoring of all available KPI’s and PI’s is done through the PRU portal which is considered as the main source of information.
Capacity planning
Capacity planning is done in line with NM’s initiative for development of a rolling NOP document in which short-term capacity and demand on the Network level is described. The expected traffic outlook is given for six weeks ahead and revised weekly, while capacity is adapted to traffic demand and reported to NM which assesses the efficiency for planned period. In the planning process on local level, several departments are involved in strategic and tactical development of the plan.
Application of Corrective Measures for Capacity (if applicable)
No data available
Factors influencing no of ATCOs include: partial reallocation of ATCOs to other duties (projects); cost containment measures; and the accelerated retirement of ATCOs, during COVID pandemic.
