Statistical presentation
Data description
The indicators described in this section address the effective use of the civil/military airspace structures.
Commission Regulation (EU) No 691 / 2010 laying down a performance scheme for air navigation services and network functions (the “performance regulation”) requires the monitoring of the effective use of civil/military airspace structures during the first reference period, with target setting being foreseen for the second reference period.
The performance regulation states in Annex IV that national authorities shall provide data in support to tasks referred to in Article 4(1 )(m) and (n) of Commission Regulation (EC) No 2150 / 2005 of 23 December 2005 laying down common rules for the flexible use of airspace (FUA). Furthermore, the performance regulation states that this data shall be provided on an annual basis.
In view of the fact that Article 4(1) (m) and (n) of Commission Regulation (EC) No 2150 / 2005 already requires Member States to assess the performance of flexible use of airspace operations, and archive data on the requests, allocation and actual use of airspace structures, it is expected that the data required is already available at a national level, most probably in the Airspace Management Cells, the AMCs.
The intention is to monitor the number of hours that special use airspace (SUA) has been reserved for restriction or segregation from general air traffic; the number of hours that it was subsequently used for such activity. Additionally, the number of hours that previously reserved airspace were returned for use by general air traffic, with a notification period of three hours or more, shall be monitored.
The two indicators described above, are known as Booking and Release Procedures.
To balance the performance measurement, we will also report on the Utilisation of Conditional Routes by general air traffic.
Classification system
Booking and Release Procedures
The data is measured for individual SUAs but is reported as an aggregated EU wide statistic.
Sector coverage
The measures pertain to the Air Transport and Air Traffic Management Sector of the economy.
Statistical concepts and definitions
Booking and Release Procedures are shown as ratios of the total amount of time that airspace was allocated for an activity requiring the restriction or segregation of other traffic.
Utilisation of Conditional Routes is shown using the FUA Indicator Rate of Aircraft Interested (RAI).
Statistical unit
Booking and Release Procedures are computed for individual Special Use Airspace (SUA). The individual SUA data is aggregated into an EU wide statistic.
Use of Conditional Routes is based on the last filed flight plan of each flight, and on individual CDRs. The individual data is aggregated into an ECAC wide statistic.
Statistical population
The statistical population comprises all special use airspace (SUA) volumes in the Single European Sky Area.
_National authorities are requested to report on SUAs that have an impact on IFR traffic, for example where:
- activation of the SUA impacts the available ATC capacity of the surrounding airspace;
- activation of the SUA impacts the availability of Conditional Routes (CDRs);
- the SUA is located in an area of Free Route Airspace._
The statistical population comprises all CDR1 and CDR2 conditional routes in the ECAC area.
Reference area
Booking and Release Procedures pertains to the Single European Sky Area.
Use of Conditional Routes pertains to the ECAC area.
Time coverage
The data will be presented from January until December, inclusive, for each calendar year beginning with 2012.
Base period
Not applicable.
Unit of Measure
Booking and Release Procedures is measured in time and is presented as a ratio.
Utilisation of Conditional Routes is measured as the number of flight plans and is presented as a ratio.
Reference period
- The first reference period (RP1) covers the calendar years 2012 to 2014 inclusive.
- The second reference period (RP2) covers the calendar years 2015 to 2019 inclusive.
- The third reference period (RP3) covers the calendar years 2020 to 2024 inclusive.
Unless decided otherwise, the following reference periods shall be of five calendar years.
Institutional Mandate
Legal acts and agreements are established in the EU IR691/2010|Performance Regulation (691 / 2010), Commission Implementing Regulation (EU) No 390 / 2013 and Commission Implementing Regulation (EU) 2019/317.

Additional definitions of the terms used in the frame of the this KPI

Quality documentation
There is no specific documentation on procedures applied for quality management and quality assessment.
Quality Management
Quality assurance
Booking and Release Procedures
The data is provided by the Member States and as such it is their responsibility to perform any quality assurance activities.
Utilisation of Conditional Routes
The data is provided by the Network Manager and as such it is their responsibility to perform any quality assurance activities.
Quality assessment
None.
Completeness
Booking and Release Procedures
The data should be collected for the entire Single European Sky Area, however, this has not yet been validated by the individual Member States.
Utilisation of Conditional Routes
The data is collected for the entire ECAC region.
Relevance
The information is published for performance monitoring purposes in accordance with the relevant EU legislation.
Accuracy and reliability
Overall accuracy
Booking and Release Procedures
It is acknowledged that, for many reasons, there will be differences between the actual time of use of an SUA and the recorded time of use. Such reasons can include safety buffers between the starting time of the booking and ensuring the area is cleared before commencing activities. In addition there can be differences due to early termination of the activity without ATC or the network being informed. A third source of errors is likely to arise in the process of recording the times, collating the aggregated times and reporting these to the European Commission via the PRU. Despite these and similar errors, since this indicator is at such a high level, it is expected to be sufficiently accurate for its purpose.
Utilisation of Conditional Routes
The metric assumes that the shortest distance is in fact the optimal route. However, it may be that the optimal route is not that which is shortest in distance, due to route charges, wind or ATFM delay. The metric also assumes that the CDR was available at the actual time of flight, although this metric is calculated post-ops using aggregated data. Despite these and similar errors, since this indicator is at such a high level, it is expected to be sufficiently accurate for its purpose.
Sampling error
There is no sampling and therefore no sampling error.
Timeliness and punctuality
Timeliness
To be determined.
Punctuality
To be determined.
Comparability
Comparability — geographical
The indicator does not change from one State to another, therefore it is comparable over geographical areas.
Comparability over time
Comparison over time is valid.
Coherence
Coherence — cross domain
The aggregated values computed here are from information made available to the EUROCONTROL Performance Review Unit. If the indicators are calculated at local level using information that is only available locally then they will most likely differ considerably.
Coherence — internal
Data is fully coherent from an internal perspective.
Cost and burden
Not available.
Data revision
The data revision policy has not yet been defined.
