3.1. Data description | |||
Datasets provided follow Regulation (EC) N°1358/2003, implementing Regulation N°437/2003 of the European Parliament and of the Council on statistical returns in respect of the carriage of passengers, freight and mail by air: Dataset A1 - Flight Stage dataset Flight Stage data registered for airport-to-airport routes, and broken down by arrivals/departures, scheduled/non-scheduled, passenger service/all-freight and mail service, airline information and aircraft type. The values provided concern passengers on board, freight and mail on board, commercial air flights as well as passenger seats available. Dataset B1 - On Flight Origin/Destination dataset On Flight Origin/Destination data registered for airport-to-airport routes, and broken down by arrivals/departures, scheduled/non-scheduled, passenger service/all-freight and mail service and airline information. The values provided concern passengers carried and freight and mail loaded or unloaded. Dataset C1 - Airport dataset Airport data registered for declaring airports. The values provided concern total passengers carried, total direct transit passengers, total freight and mail loaded or unloaded, total commercial aircraft movements and aircraft movements. |
|||
3.2. Classification system | |||
Airports (reporting airports and partner airports) are coded using the 4-letter ICAO codes as listed in the ICAO Document 7910. The airport codes are composed as a concatenation of the ICAO Aeronautical fixed service area codes (first digit), ICAO country identifier codes (second digit) and national telecommunication center identifier codes (third and fourth digit); the airport code is thus a four digits alphanumeric code. The airport codes are to be used in all datasets for the reporting airport and also (in A1 and B1) for the If the partner airport is unknown, the code to be used to report data is "ZZZZ".are classified according to ICAO (International Civil Aviation Organization) airport codes as listed in ICAO document 7910. Aircrafts are coded following the 4-letter codes of the ICAO aircraft type designators, as listed in ICAO Document 8643. Eurostat provides the updated list of aircraft codes to all reporting countries on a regular basis (approximately every quarter) via EDAMIS as the 'AIR_ICAO_Q' data set. For unknown type of aircraft, the "ZZZZ" code has to be used. Air Transport Operators are classified using the 3-letter air transport operator code as listed in ICAO Document 8585 as an obligatory level of detail for all data provisions to Eurostat. However, this information might be regarded as sensitive, and/or would be difficult to obtain from airport authorities. That is why Commission Regulation 1358/2003 gives the list of codes to be used alternatively for the provision of information related to the airline. One of the codification approaches listed below (from the most to least detailed) is used:
|
|||
3.3. Coverage - sector | |||
Air transport - commercial air services and civil aircraft movements for the airports with traffic in excess of 15 000 passenger units annually. |
|||
3.4. Statistical concepts and definitions | |||
The main concepts used in this domain are the following: Community airport - a defined area on land or water in a Member State subject to the provisions of the treaty, which is intended to be used either wholly or in part for the arrival, departure and surface movement of aircraft and open for commercial air services. Flight stage - the operation of an aircraft from take-off to its next landing. This is linked to the definition of passengers (or freight and mail) on board. Passengers on board - all passengers on board of the aircraft upon landing at the reporting airport or at taking off from the reporting airport. All revenue and non-revenue passengers on board an aircraft during a flight stage. Includes direct transit passengers (counted at arrivals and departures). Direct transit passengers - passengers who, after a short stop, continue their journey on the same aircraft on a flight having the same flight number as the flight on which they arrive. Transfer of indirect transit passengers - passengers arriving and departing on a different aircraft within 24 hours, or on the same aircraft bearing different flight numbers. They are counted twice: once upon arrival and once on departure. Freight and mail on board - all freight and mail on board of the aircraft upon landing at the reporting airport or at taking off from the reporting airport. All freight and mail on board an aircraft during a flight stage. Includes direct transit freight and mail (counted at arrivals and departures). Includes express services and diplomatic bags. Excludes passenger baggage. On flight origin and destination - traffic on a commercial air service identified by a unique flight number subdivided by airport pairs in accordance with point of embarkation and point of disembarkation on that flight. For passengers, freight or mail where the airport of embarkation is not known, the aircraft origin should be deemed to be the point of embarkation; similarly, if the airport of disembarkation is not known, the aircraft destination should be deemed to be the point of disembarkation. This is linked to the definition of passengers carried and freight and mail loaded or unloaded. Passengers carried - all passengers on a specific flight (with one flight number) counted once only and not repeatedly on each individual stage of that flight. All revenue and non-revenue passengers whose journey begin or terminates at the reporting airport and transfer passengers joining or leaving the flight at the reporting airport. Excludes direct transit passengers. Freight and mail loaded or unloaded - all freight and mail loaded onto or unloaded from an aircraft. Includes express services and diplomatic bags. Excludes passenger baggage. Excludes direct transit freight and mail. Passenger unit - one passenger unit is equivalent to either one passenger or 100 kilograms of freight and mail. |
|||
3.5. Statistical unit | |||
The data are collected at individual airport level. |
|||
3.6. Statistical population | |||
Four categories of Community airports are defined by the Regulation (EC) N°1358/2003:
Airports under category ‘0’ are not included in the statistics provided to Eurostat. |
|||
3.7. Reference area | |||
Commercial airports located at the territory of Spain. |
|||
3.8. Coverage - Time | |||
All data sets have been provided according to the legal act (with no derogations) starting from 2001 reference year. Some partial information available: annual data on passengers carried and freight and mail loaded and unloaded (1993-1999) and monthly data on passengers carried and freight and mail loaded and unloaded for the reference year 2000. Monthly data on commercial passenger and freight flights are available as from reference year 2000. |
|||
3.9. Base period | |||
Not applicable. |
|
|||
The units used depend on the variables collected within each data set and are: number of passengers, tonnes, flights, aircraft movements and passenger seats available. The weight of freight and mail is transmitted in tonnes with three decimal places (as from reference year 2016). |
|
|||
Reference year is the calendar year 2022. |
|
|||
6.1. Institutional Mandate - legal acts and other agreements | |||

10.6. Documentation on methodology | |||
The Reference Manual on Air Transport Statistics - contains detailed methodological information as well as background information on the implementation of the legal acts and on how data are processed and disseminated by Eurostat. Additional definitions of the terms used in the frame of the statistics on air transport are available in the "Glossary on Air Transport Statistics". |
|||
10.7. Quality management - documentation | |||
The Reference Manual on Air Transport Statistics includes a dedicated section describing the quality checks applied to the incoming data as well as showing the results of the quality analysis of the data received. |
|
|||
11.1. Quality assurance | |||
The system on statistics on air transport follows as far as possible the European Statistics Code of practice and Quality Assurance Framework of the European Statistical System, more precisely Principle 4: Commitment to Quality. Data quality is ensured by the implementation of a common and well established methodology (Reference manual on air transport statistics) for the data collection and compilation at country level. Data is subsequently validated in Eurostat by applying different controls (codification, format checks, consistency over time, inter-datasets checks) on every incoming data set, before and after treatment, as well as by cross-checking partner countries figures (mirror statistics). The results of data quality control are always provided to the reporting country either for information or for comments or/and corrections. |
|||
11.2. Quality management - assessment | |||
Data quality can be assessed as good and there is a set of validation rules and quality checks done. Mirror checks and checks for consistency over time are done as well. New version of EDAMIS for validation datasets allows to correct any structural error before final data submission. Moreover, annually, Eurostat provides a data quality report with a summary of the main findings affecting data quality. |
|
|||
12.1. Relevance - User Needs | |||
The usual users of air transport data are people from different Commission Services or other European institutions (e.g.: DG MOVE, DG REGIO, DG COMP, the European Court of Auditors), National Statistical Authorities, international or other governmental institutions (Ministries of Transport), universities or research institutions, journalists as well as the users involved in the industry as airlines, airports or air traffic management. Users mainly request these data to properly monitor the development of air transport in the EU and other European countries, evaluate the impact of the air transport industry in the economy, quantify the importance of the transport flows of passengers and freight at intra-EU and extra-EU level and assess the competition in the air transport market. |
|||
12.2. Relevance - User Satisfaction | |||
There is no user survey especially on air transport statistics data carried out. |
|||
12.3. Completeness | |||
The collection of data on air transport statistics is carried out in accordance with the provisions of Regulation 437/2003. All variables in all three data sets are provided except voluntary variable (transfer passengers). |
|
|||
13.1. Accuracy - overall | |||
Overall accuracy of the data is good. Regular mirror checks excercises and comparisons with other relevant international sources (ICAO, airports and airlines data) shows a high level of comparability. |
|||
13.2. Sampling error | |||
Not applicable for air transport data collection. |
|||
13.3. Non-sampling error | |||
Not applicable for air transport data collection. |
|
|||
14.1. Timeliness | |||
All the statistics required by the provisions of the Regulation 437/2003 are transmitted to Eurostat within 1 or 2 months after the reference month. |
|||
14.2. Punctuality | |||
All the statistics required by the provisions of the Regulation 437/2003 are available before the deadline for the data provisions set up in the legal act. |
|
|||
15.1. Comparability - geographical | |||
There are no problems of comparability for air transport data collection with a very high data comparability across countries due to the common legal basis. Comparisons of the data regarding passengers and freight/mail declared by partner reporting airports (so-called mirror checks) by Eurostat allow further detection of possible inconsistencies which can be corrected if possible. |
|||
15.2. Comparability - over time | |||
As from 2003 the statistics on air transport are comparable over time, as they are collected following fully the provisions of the legal act (Regulation 437/2003). The series breaks occur in case of:
Detailed information on eventual breaks in the time series is provided in the Country Specific Notes (CSNs), List of reporting airports - time series as well as in List of reporting airports files. The data collected before 2003 (before the legal act was introduced) might not be fully coherent with the ones collected nowadays. |
|||
15.3. Coherence - cross domain | |||
Comparisons with other transport statistics are only partially and to a limited extent possible with regard to freight transport and passenger transport, since data are currently not available or are not collected at the same level of detail and also different methods and underlying objectives. |
|||
15.4. Coherence - internal | |||
Coherence between datasets is good. Mirror and missing routes checks provided by Eurostat allow the identification of possible inconsistencies that are corrected as far as possible. |
|
|||
There is not estimation of direct cost and burden associated with the collection and production of a statistical product, as long as it is done integrated with other tasks related with statistical works. |
|
|||
17.1. Data revision - policy | |||
Eurostat takes into account any revisions of the data already provided by the reporting countries and disseminated in Eurostat's on-line database. Revised figures are not flagged with ‘r’ revision flag. Substantial data revisions (that affect EU aggregates) are noted down in the Country Specific Notes (CSNs) file. |
|||
17.2. Data revision - practice | |||
Every incoming data set is subsequently validated in Eurostat by applying different controls - codification, format checks, consistency over time, inter-datasets checks. Eurostat comes back to the reporting country asking for clarifications or/and revisions in case of any issues detected or doubts. Only data that passes through all controls are considered as final and are put into dissemination. Any further revisions provided by a reporting country are always taken into account and disseminated, replacing the previous figures. In case of substantial revisions a note is prepared and available in the Country Specific Notes (CSNs) usually providing the reason for the data revisions. The dedicated flag 'r' (indicating revised figures) is not applied in the dissemination of air transport data. |
|
|||
18.1. Source data | |||
Dataset A1- Flight Stage dataset: AENA airports Dataset B1 - On Flight Origin/Destination dataset: AENA airports Dataset C1 - Airport dataset: AENA airports |
|||
18.2. Frequency of data collection | |||
Information needed for datasets A1, B1 and C1 are collected on monthly basis. |
|||
18.3. Data collection | |||
Data is transmitted to Eurostat using the EDAMIS engine tool following the transmission format foreseen in the Regulation 1358/2003. |
|||
18.4. Data validation | |||
Data validation takes place at several levels of the data processing. The first step is the automatic validation during the integration, and the second step is the quality checks when data has been integrated. Automatic validation The checks especially ensure that:
Quality checks Three types of quality checks are made on the datasets received for national and international transport.
|
|||
18.5. Data compilation | |||
DGAC obtains the data from AENA airports monthly and when it is time to send the data to Eurostat, files are generated, using a management app for processing the data. Then, after a preliminary process of validation, files are upload to EDAMIS website for the review of the team of Eurostat. Later, DGAC recieves an email from Eurostat with the Quality report and analysis of the data. DGAC does a new revision of the data and explains with the differences and, if necessary, upload new files. |
|||
18.6. Adjustment | |||
Not applicable for air transport data collection. |
