Download Report

PRB monitoring

▪ Czech Republic achieved a KEA performance of 2.03% compared to its target of 2.05% and contributed positively towards achiev-ing the Union-wide target. This is the best performance since 2017.

▪ The NSA states the main step taken to improve KEA was the implementation of free route airspace in February 2021, which allows shorter routes and increases the options for route planning.

▪ Both KEP and SCR were further reduced in comparison with 2020 and are at the lowest since 2017. The value of these two indicators is similar, meaning airspace users plan close to the shortest route available.

▪ The proportion of CDO flights remains at similar levels to 2020.

▪ During 2021, additional time in terminal airspace decreased from 0.67 to 0.50, however, additional taxi out time increased from 1.36 to 1.76 min/flight. Both values are lower than those seen in RP2.

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)

Focus on ASMA & AXOT

AXOT

Additional taxi-out times at Prague increased in 2021 (LKPR; 2020: 1.36 min/dep.; 2021: 1.76 min/dep.), but they were still 37% lower than in 2019. These additional times are always much higher in the winter months (probably related to de-icing procedures)
According to the Czech Republic’s monitoring report: The development of PI #3 is mainly influenced by the volume of traffic and its structure (gradual return of traffic after the COVID-19 pandemic). Another factor influencing its development is the volume of days when it is necessary to de-icing aircraft that are in remote staging (i.e. within taxi-out phase) at LKPR.
The PI monitoring is part of annual monitoring of the ANSP performance (on quaterly basis) to the CAA.

ASMA

The yearly average of the additional times in the terminal airspace decreased in 2021 (LKPR; 2019: 1.47 min/arr.; 2020: 0.67 min/arr.; 2021: 0.5 min/arr.). However the performance has slightly deteriorated with respect to the period April-December 2020, in line with the traffic recovery.
According to the Czech Republic’s monitoring report: No formal initiatives were implemented, but if traffic permits the aircrafts are allowed for direct routing.
The PI monitoring is part of annual monitoring of the ANSP performance (on quaterly basis) to the CAA.

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

Focus CDOs

The share of CDO flights decreased at Prague to 25.9% which is lower than the overall RP3 value in 2021 (30.5%).
The monthly values dropped significantly as from May with values staying below 27%.
According to the Czech Republic’s monitoring report: There is no CDO officialy published procedure in FIR Prague, but if traffic permits clearence are issued in order to allow CDO.
The PI monitoring is part of annual monitoring of the ANSP performance (on quaterly basis) to the CAA.

Update on Military dimension of the plan

There is a significant impact of MIL activities on the ENV indicators. The military has the lead role in the AMC, the ANSPs has no power to evaluate the airspace reservation by the military. In any case, the implementation of FUA is regularly evaluated through monitoring organized by the CAA. The administrators of the individual TRA / TSA (mostly represented by MAA) submit the evaluation of the plans and the activation of these airspaces on a monthly basis to CAA, and any deficiencies are addressed within the ASMCG meetings or individually with specific administrators, if needed.

Airspace Charter of the Czech Republic describes the competent authorities (CIV and MIL), their responsibilities and principles by which a joint civilian-military body (ASM Committee - ASMC) carries out strategic planning for the use of the Czech Republic airspace. The Charter incorporates as annexes the descriptions of processes used to provide high quality services to airspace users and ATS providers through safe, accurate and timely planning, approval and promulgation of national airspace management measures and international cooperation. The Airspace Charter was udated at the end of 2021.

The airspace of the Czech Republic is open to flights and it is divided in accordance with the rules contained in Sections 44 - 44c) of Act No. 49/1997. Pursuant to Section 44(2) of the Act, the CAA issues, in agreement with the Ministry of Defence and after consulting the Person authorized to exercise state administration in the matters related to sport flying devices, measures of general nature under the Administrative Procedure Code on division of the airspace of the Czech Republic to ensure safe conduct of flights and efficient provision of air services. In fulfilment of that mandate, the CAA takes into account, where possible, the FUA specifications described in “EUROCONTROL Specifications for the Application of the Flexible Use of Airspace (FUA)”. Consultation with airspace users, service providers and other relevant bodies is conducted with the aim of obtaining consensus, wherever possible, before making changes in the planning or design of airspace management. The consultations are performed in a transparent way following a predefined procedure. The ASMC ensures effective cooperation at all levels through the ASM Consultation Group (ASMCG). In application of Regulation (EC) No 2150/2005, the ASMC cooperates very closely with CAA and takes into account the findings and relevant corrective measures resulting from control activities (e.g. CAA, MAA, EASA). In accordance with ICAO requirements, the CAA publishes the airspace management policy and implementation of new airspace structures and follow-up procedures or their changes so that all airspace users and ATS providers have sufficient time to comply with the new requirements.

Dynamic Airspace Management is realized at ASM Level 2 and/or ASM Level 3. Areas published in AIP CR / MIL AIP or other pre-arranged areas can be used under FUA rules as AUP manageble with UUP function updates.
The ATM systems of the Czech Airforces are directly connected to the ANS CR systems in order to present current status of reserved areas to the ATCOs. The AIM/AIS provider promulgates the planning status of the airspaces concerned in AISVIEW web tool, which serves for airspace users as an information source.
On the local level the FUA is addressed within the AMC activities, on the FAB CE level the DAM/STAM projects are in progress.The AMC is newly certificated under the EU 2017/373. The regulation 2150/2005 is fully implemented within the Czech Republic.

Military - related measures implemented or planned to improve capacity

The traffic complexity manager (a tool developed with the SESAR support) was put into full operational use in 2020. The tool is predicting traffic load in particular sectors (including military activities) and thus allowing for better ATCOs usage and improvement in capacity area.

The establishment of Airspace designer function was preparing during the year 2021 to be ready at the begining of 2022 and serves as a goverment service for professional preparation of requests and supporting documentation for all changes in the airspace structures in future.

Initiatives implemented or planned to improve PI#6

[As previously documented in update of military dimension of the plan plus..]

The performance monitoring and the assessment and review of FUA operational performance are organised by CAA and MAA.
Dynamic Airspace Management is realized at ASM Level 2 and/or ASM Level 3. Areas published in AIP CR / MIL AIP or other pre-arranged areas can be used under FUA rules as AUP manageble with UUP function updates. FUA evaluation is performed monthly by individual TRA / TSA administrators and reported to the CAA. Deficiencies are addressed both within the ASMCG meetings and individually with individual administrators, if needed.
The MAA was informed about the negative trend in proportion of planned and subsequently used airspace in 2021 with aim to asked MIL for implementation of appropriate remedy actions.
