Terminal air navigation service costs and unit rates

Data description

The measure addresses the costs for the provision of terminal air navigation services.

The European Commission is required to collect, consolidate and monitor Terminal ANS Costs and the Terminal ANS Unit Rate.

The EC Charging Scheme (EC 1794 / 2006) for air navigation services contributes to greater transparency in the determination, imposition and enforcement of charges to airspace users and also contributes to the cost efficiency of providing air navigation services and to efficiency of flights, while maintaining an optimum safety level.

The cost of air navigation services comprise for the most part, two elements:

• en-route costs,
• terminal costs.

The cost of terminal services is related to the following services:

• airport control services, airport flight information services including air traffic advisory services, and alerting services;
• air traffic services related to the approach and departure of aircraft within a certain distance of an airport on the basis of operational requirements;
• an appropriate allocation of all other air navigation services components, reflecting a proportionate attribution between en-route and terminal services.

The concepts of terminal ANS costs and unit rates are linked by the charges paid by airspace users. These charges are equal to the total number of service units multiplied by the terminal unit rate.

Classification system

Terminal air navigation services costs and unit rates are classified per Terminal Charging Zone within the Single European Sky Area.

Each Terminal Charging Zone belongs to a single State in the zone.

Sector coverage

The measures pertain to the Air Transport and Air Traffic Management Sector of the economy.

Statistical concepts and definitions

All cost values are expressed as:

• Euro or National currencies outside the Euro area,
• costs in Real terms,
• costs in Nominal terms.

Statistical unit

The statistical unit is the Terminal Charging Zone.

Statistical population

The statistical population comprises the Terminal Charging Zones the Single European Sky Area.

Reference area

The reference area is the Single European Sky Area.

Time coverage

Actual Costs are measured over the period 2012 to the year before the current year.

Base period

2009 is the base year for the calculation of cost series in Real terms.

Release calendar

The Terminal ANS costs and unit rates are released twice a year.

Release calendar access

Not applicable.

User access

Information is disseminated to the general public via the SES Data Portal.

Documentation on methodology

As per the pertaining regulations (see Institutional Mandate).
For technical questions not addressed in Statistical processing please contact: [email protected].
Additional definitions of the terms used in the frame of the this KPI are available in the Metadata page.

Quality documentation

There is no specific documentation on procedures applied for quality management and quality assessment.

Quality assurance

The data is provided by the concerned States 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.

Quality assessment

EUROCONTROL performs systematic checks to verify that totals do indeed equal the sum of their parts. However, if discrepancies are found, they are simply reported to data provider who may or may not make corrections.

EUROCONTROL does not change data elements nor does it prevent the publication of data that failed to verify the checks.

Overall accuracy

This data is provided by the States and displayed as provided. It is assumed that the States have provided perfectly accurate data.

Sampling error

There is no sampling and therefore no sampling error.

Timeliness

The latest data displayed represents costs and rates that are at least eleven months old.

Punctuality

The data is provided by the States in June and November and is displayed to the public at the end of November.

Comparability — geographical

Depending on the State, terminal charging zones may include from one to more than sixty airports, which would tend to reduce the validity of geographical comparison.

Comparability over time

The exact composition of a given terminal charging zone may vary over time, e.g. changes in the number of airports concerned, which would tend to reduce the comparability over time.

Coherence — cross domain

Generally, data should be coherent with ATM Cost-effectiveness (ACE) information.

Coherence — internal

The data is assumed to be internally coherent as provided.

Source data

Frequency of data collection

The data is collected twice a year (June & November).

Data collection

Air navigation service providers are required to fill a reporting table for each terminal charging zone under their responsibility and supply it to the European Commission (Charging Regulation (EC 1794 / 2006)).

Data validation

The data is validated by the States/data providers under their own responsibility.

Data compilation

The data provided is loaded into a database at EUROCONTROL but no aggregation or modification is performed.

Adjustment

No adjustments are performed on this data.
