PRB monitoring

▪ Greece achieved a KEA performance of 2.19% compared to its target of 1.92% and did not contribute positively towards achieving the Union-wide target.

▪ The NSA states that the target was missed mainly due to military activity, adverse weather phenomena and high levels of traffic.

▪ KEP improved and SCR improved marginally in comparison with 2023. Despite the KEA target being missed, KEA improved in 2024.

▪ The share of CDO flights increased from 43.31% to 46.42% in 2024.

▪ Additional taxi out time increased marginally from 2.85 to 2.95 min/flight, while additional time in terminal airspace increased from 1.44 to 1.55 min/flight in 2024 compared to 2023.

En route performance

Horizontal flight efficiency of the actual trajectory (KEA) (KPI#1), of the last filed flight plan (KEP) (PI#1) & shortest constrained route (SCR) (PI#2)

Terminal performance

Additional taxi-out time (AXOT) (PI#3) & Arrival Sequencing and Metering Area (ASMA) time (PI#4)

AXOT

Additional taxi-out times at Athens (LGAV: 2019: 2.61 min/dep.; 2020: 1.54 min/dep.; 2021: 2.12 min/dep.; 2022: 3.18 min/dep.; 2023: 2.85 min/dep.; 2023: 2.95 min/dep.) increased slightly in 2024 and sit above the SES average of 2.91 min/dep.

ASMA

The additional times in the terminal airspace (LGAV; 2019: 1.30 min/arr.; 2020: 1.03 min/arr.; 2021: 1.15 min/arr.; 2022: 1.37 min/arr.; 2023: 1.44 min/arr.; 2023: 1.55 min/arr.) observed a gradual increase during RP3, and in 2024 was higher than in 2019 and than the SES average for 2024 (1.28 min/arr)

Share of arrivals applying continuous descent operations (CDOs) (PI#5)

The share of CDO flights at Athens (LGAV) has increased in 2024 to 39.2% which is above the overall RP3 value in 2024 (29.3%). The monthly values ranged from 35.9% in January to 42.0% in November.

Civil-Military dimension

Update on Military dimension of the plan

Air military activities (training exercises and operations), can significantly impact airspace environment and capacity (KPAs), potentially leading to both reduced capacity and disruptions of civil air traffic as they restrict the use of that airspace leading to delays, inefficiencies, and increased fuel consumption, all of which have environmental implications.

Military air traffic, while vital for national security and defense, has a significant environmental footprint that needs to be addressed. Recognizing this impact within a KPA is crucial for developing effective strategies to mitigate the negative environmental consequences and ensure sustainable air traffic management.

In order to ensure efficient use of airspace and minimizing environmental impacts; effective planning (through optimization of flight paths and procedures) reducing noise pollution and emissions, as well as the coordination between military and civil aviation stakeholders could be effective in minimizing environmental impacts. The scale of impact can range since it is directly proportional to the frequency and intensity of military operations in the relevant airspace.

Military - related measures implemented or planned to improve capacity

The application of FUA principles and practices has been a major enabler for the continuous ATC capacity increase and flight-efficiency improvements while releasing enough airspace to military forces. However, allocation and use of airspace could be further improved. Under the current operating mode, the route network is a fundamental piece of the ATM system. The safe ATC capacity requires the systematisation of traffic flows through the route network design and associated rules governing the route utilisation. The configuration of shared airspace and ATC sector configuration is more important for flight planning as it relates directly to the production of ATC capacity and the airspace availability for military training. The mitigation measure to improve airspace capacity impact is the flexible sector configuration through ASM advanced technology tools/systems (e.g. LARA/PRISMIL).
