The measure addresses the costs for the provision of en route air navigation services.
In accordance with EU IR691 / 2010, Single European Sky Area States are required to adopt performance targets contributing adequately to and consistent with the [EU wide targets]. The cost efficiency KPI for the first reference period is the Determined Unit Rate for en route Air Navigation Services.
The en route ANS Determined Unit Rate is defined as the en route determined costs (in real terms) divided by the total en route service units. The yearly values of the determined costs are fixed in advance, for the entire reference period. While monitoring performance, the en route actual unit cost (en route actual costs/actual en route service units) is compared against the determined unit rate.
It must be noted that the determined en route unit rates differ from the actual en route unit rates charged to users in application of the Charging Regulation which also takes into account, where applicable:
- the application of the difference between forecast and actual inflation,
- the carry-overs resulting from the implementation of the traffic risk-sharing,
- the carry-overs from the previous reference period resulting from the implementation of the cost risk-sharing,
- bonuses and penalties resulting from the financial incentives to the achievement of capacity performance targets,
- the over or under recoveries incurred by Member States up to the year 2011 included (for the first two reference periods),
- a deduction of the costs of VFR flights,
- a deduction for income from other revenues, where applicable.
Average horizontal en route inefficiency is calculated for the reference area.
Complementary to the EU-wide KPI, a number of additional Horizontal flight efficiency calculations are carried out for monitoring purposes.
The measures pertain to the Air Transport and Air Traffic Management Sector of the economy.
Statistical concepts and definitions
Of interest for the calculation are the Great Circle reference area end-points (referred to as onset and terminus) and the couple(s) of entry/exit points in the measured area of the en-route portion of the flight model (i.e., excluding a 40 NM circle around the airports). More details are provided in Horizontal flight efficiency calculations.
The statistical unit is a geographical area.
The statistical population comprises only one geographic area in RP1: the Single European Sky Area. In RP2 it includes units at the local level (e.g., FABs).
The reference area is the Single European Sky Area.
Data is available from 2011.
Unit of Measure
The KPI is presented as a percentage.
- 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.
Unless decided otherwise, the following reference periods shall be of five calendar years.
Legal acts and agreements are established in the Performance Regulation (691 / 2010) and Commission Implementing Regulation (EU) No 390 / 2013.
- The information is disseminated in accordance with Article 21 of the Performance Regulation (691 / 2010).
- The information is disseminated in accordance with Article 22 of the Commission Implementing Regulation (EU) No 390 / 2013.
The indicator values are released monthly.
Release calendar access
Information is disseminated to the general public via the SES Data Portal.
Frequency of dissemination
Data is published monthly with the annual performance aggregate being available in January of the following year.
Information is disseminated to the general public via the SES Data Portal.
Accessibility of documentation
Documentation on methodology
As per the pertaining regulations (see Institutional Mandate).
For technical questions not addressed in Statistical processing please contact: PRU-Support@eurocontrol.int.
Additional definitions of the terms used in the frame of the this KPI are available in the Metadata page.
There is no specific documentation on procedures applied for quality management and quality assessment.
The data is provided by the Network Manager and as such it is their responsibility to perform any quality assurance activities.
EUROCONTROL is not responsible for the procedures and processes used in the production of this data.
Data is validated by random quality checks, e.g. missing data for given a day, adherent data, etc. Any issues are reported to the Network manager who works with the EUROCONTROL Performance Review Unit to resolve them.
The information is published for performance monitoring purposes in accordance with the relevant EU legislation.
Accuracy and reliability
This data is provided by the Network manager and apart from the basic consistency checks, it is assumed that the data is accurate.
There is no sampling and therefore no sampling error.
Timeliness and punctuality
The data is published each month - in general between 14 and 16 days after the end of the month in question.
To be determined.
Comparability — geographical
Not applicable: there is only one reference area.
Comparability over time
It is assumed that this highly aggregated indicator will remain comparable over time.
Coherence — cross domain
Generally, data should be similar to flight efficiency data published in other sources.
Coherence — internal
The data is assumed to be internally coherent as provided.
Cost and burden
The data revision policy has not yet been defined.
The source data is provided by the Network Manager and is processed by EUROCONTROL.
Frequency of data collection
The data is collected daily.
The Network Manager provides information concerning several different Flight models and their intersections with airspaces of interest, such as the TMA areas around the airports and the FIRs.
The data is validation as described in the Quality Management section.
Computation of the en route section and the quantities needed for the computation of the KPI are performed at EUROCONTROL and stored in a local database.
The calculation of the KPI in the 1st reference period (2012-14) is based on the Filed Tactical Flight Model (FTFM) which corresponds to the last filed flight plan (see also Horizontal flight efficiency calculations).
No adjustments are performed on this data, although invalid data elements are rejected.
