Safety - Estonia

PRB monitoring

▪ EANS already achieved the RP3 EoSM targets at the start of the reference period and continued to improve the SMS throughout RP3.

▪ Estonia recorded a significantly higher rate of runway incursions (RIs) in 2024 compared to 2023, while lowering the rate of separation minima infringements (SMIs).

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

Focus on EoSM

All five EoSM components of the ANSP meet, or exceed the RP3 target level. Maximum maturity level was maintained over 2024.

Estonia achieved the RP3 EoSM target levels at the start of the reference period and continued to improve its SMS reaching maturity level D for all Management Objectives already in 2022.

EANS states that it continues to meet its safety performance targets in accordance with the Estonian State safety program, demonstrating effective implementation of its SMS and a sustained commitment to national safety objectives.

Safety occurrences

Rate of runway incursions (RIs) (PI#1)

Rate of RIs per 100,000 airport movements - Estonia
#	Airport name	APT movements	Number of RI	Rate RI per 100,000
1	Tallinn	42,403	0	0.00
2	Tartu	4,109	0	0.00

Focus on runway incursions

After a peak in 2021, Estonia recorded a stable rate of RIs until 2024, which showed a sharp increase in the rate due to a relative high number of RIs without ANS contribution. The larger airports in Estonia did not contribute to this increase.

The NSA closely monitored the rate of RI occurrences and introduced mitigation measures for all relevant stakeholders (mainly related to vehicle movements and private pilots).

Rate of separation minima infringements (SMIs) (PI#2)

Rate of SMI with ANS contribution per 100,000 flight hours

Focus on separation minima

Estonia started RP3 with a high rate of SMIs exceeding the Union-wide average and started improving in 2022 moving below the average with a downward trend despite the increase in number of flight hours.

The NSA notes that the actions to provide regular training sessions and the improved organization of ATCOs’ work has improved the situation regarding SMI occurrences.
