3. Statistical presentation
3.1. Data description
The measure provides an indication of the flight efficiency en route.
The average horizontal en-route flight efficiency indicator compares the length of the en-route part of flight trajectories with a corresponding portion of the Great Circle (defined with respect to the reference area). ‘En-route’ is defined as the distance flown outside a circle of 40 NM around the airport.
In the first reference period (2012-14) the calculation of the KPI is based on the Filed Tactical Flight Model (FTFM) which corresponds to the last filed flight plan (see also Horizontal flight efficiency calculations).
3.2. Classification system
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.
3.3. Sector coverage
The measures pertain to the Air Transport and Air Traffic Management Sector of the economy.
3.4. 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.
3.5. Statistical unit
The statistical unit is a geographical area.
3.6. Statistical population
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).
3.7. Reference area
The reference area is the Single European Sky Area.
3.8. Time coverage
Data is available from 2011.
3.9. Base period
4. Unit of measure
The KPI is presented as a percentage.
5. 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.
Unless decided otherwise, the following reference periods shall be of five calendar years.
6. Institutional Mandate
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 Commission Implementing Regulation (EU) No 390/2013.
8. Release policy
8.1. Release calendar
The indicator values are released monthly.
8.2. Release calendar access
8.3. User access
Information is disseminated to the general public via the EUROCONTROL website.
9. Frequency of dissemination
Data is published monthly with the annual performance aggregate being available in January of the following year.
10. Dissemination format
The information is available on the EUROCONTROL website.
11. Accessibility of documentation
11.1. Documentation on methodology
As per the pertaining regulations (see Institutional Mandate).
For technical questions not addressed in Statistical processing or in Horizontal flight efficiency calculations please contact: NSA-PRU-Support@eurocontrol.int.
Additional definitions of the terms used in the frame of the this KPI are available in the Glossary.
11.2. Quality documentation
There is no specific documentation on procedures applied for quality management and quality assessment.
12. Quality Management
12.1. Quality assurance
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.
12.2. Quality assessment
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.
14. Accuracy and reliability
14.1. Overall accuracy
This data is provided by the Network manager and apart from the basic consistency checks, it is assumed that the data is accurate.
14.2. Sampling error
There is no sampling and therefore no sampling error.
15. 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.
16.1. Comparability — geographical
Not applicable: there is only one reference area.
16.2. Comparability over time
It is assumed that this highly aggregated indicator will remain comparable over time.
17.1. Coherence - cross domain
Generally, data should be similar to flight efficiency data published in other sources.
17.2. Coherence - internal
The data is assumed to be internally coherent as provided.
18. Cost and burden
19. Data revision
The data revision policy has not yet been defined.
20. Statistical processing
20.1. Source data
20.2. Frequency of data collection
The data is collected daily.
20.3. Data collection
20.4. Data validation
The data is validated as part of the quality assessment described in Section 12.2.
20.5. Data compilation
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.
