Safety - Czech Republic

PRB monitoring

▪ ANS CR exceeded the RP3 EoSM targets as early as 2020 and remained at this maturity level throughout RP3.

▪ The Czech Republic has recorded a stable level of runway incursions (RIs) over RP3, while a marked reduction of the rate of separation minima infringements (SMIs) over RP3 going from above the Union-wide average to go well below.

Effectiveness of Safety Management (EoSM) (KPI#1)

Focus on EoSM

All five EoSM components of the ANSP meet, or exceed, the RP3 target level, with only one question below maximum maturity.

ANS CR exceeded the RP3 EoSM targets as early as 2020 and has shown a constant level of performance over RP3. In 2024, the organisation took additional steps to further enhance its SMS function by improving the process for assessing the safety implications of the functional system. Human factors and human performance training was also further extended and refined, with a particular focus on fatigue risk management, team resource management, and other contributing factors.

Focus on runway incursions

The Czech Republic has seen a stable level of runway incursions (RIs) over RP3 with a marginal increase between 2023 and 2024. The 2024 rate of RIs is at the level of the Union-wide average, mainly driven by airports which are not part of the performance plan .

Focus on separation minima

Over RP3, the Czech Republic has recorded a significant reduction in the rate of SMIs being since 2022 well below the Union-wide average. The positive trend continued in 2024 with a further reduction of the rate.

The rate of SMIs with ANS contribution also declined over RP3, but with a slower pace. The number of occurrences remained at a similar level despite an increase in traffic.

The NSA closely monitors the rate of occurrences and assesses the effectiveness of implemented measures through regular meetings of its safety board.
