3.1. Data description | |||
The statistics on commercial aviation covers scheduled and non-scheduled air traffic at the five Belgian airports Brussels National Airport (EBBR), Charlerloi/Brussels South (EBCI), Antwerpen/Deurne (EBAW) , Liege (EBLG) and Oostende/Brugge (EBOS). Based on European legal bases results are transmitted to the statistical office of the European Union (Eurostat) six months after the reference quarter in the form of aggregated monthly data. Dataset B1 - On Flight Origin/Destination dataset : periodic 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: periodic airport data registered for declaring airports, and broken down by airline information. The values provided concern total passengers carried, total direct transit passengers, total transfer (indirect transit) passengers (optional variable), total freight and mail loaded or unloaded, total commercial aircraft movements and total aircraft movements. Data sets A1 and B1 are provided on monthly basis, while data set C1 is provided on annual basis including the optional variable - total number of transfer passengers.
|
|||
3.2. Classification system | |||
Airports are classified according to ICAO (International Civil Aviation Organization) airport coded as listed in ICAO document 7910. Aircrafts are classified according to aggregated aircraft categories based on the ICAO aircraft codes as listed in ICAO document 8643. Airlines are classified according to the ICAO airline codes as listed in the ICAO document 8585. When providing the data to Eurostat, the region where they are licensed is coded accordingly either as European Union (EU) or outside the European Union (non-EU). |
|||
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 | |||
International airports located on the territory of Belgium. |
|||
3.8. Coverage - Time | |||
All data sets have been provided according to the legal act (with no derogations) starting from 2002 reference year. Partial information (annual aggregates on passenger transport only) are available starting from 1993 reference year. |
|||
3.9. Base period | |||
Not applicable. |
|
|||
The units used depend on the variables collected within each data set and are: number of passengers, kilogrammes (for freight and mail), aircraft movements and passenger seats available. According to the legal act the weight of freight and mail is transmitted in tonnes with three decimal places. |
|
|||
2022 Data is collected on a monthly basis for the purpose of data sets A1 and B1 and on annual basis for the purpose of data set C1. |
|
|||
6.1. Institutional Mandate - legal acts and other agreements | |||

Not applicable. |
|
|||
7.1. Confidentiality - policy | |||
National level:
European level:
The data provided to Eurostat in the data sets A1, B1 and C1 contain no confidential information. |
|||
7.2. Confidentiality - data treatment | |||
Only the airline information data is subject to confidentiality. Before providing the data to Eurostat, the region where they are licensed is coded accordingly either as European Union (EU) or outside the European Union (non-EU). The data provided to Eurostat in the data sets A1, B1 and C1 contain no confidential information. Data confidentiality problems: The airline information is confidential. |

12.1. Relevance - User Needs | |||
The key users of air transport statistics collected according to the Regulation 437/2003 are:
|
|||
12.2. Relevance - User Satisfaction | |||
not known |
|||
12.3. Completeness | |||
not known |
|
|||
13.1. Accuracy - overall | |||
Overall accuracy of the air transport statistics data is good. The processing with several plausibilty checks as well as checks done before transmitting data to Eurostat provides a satisfactory accuracy of the data. |
|||
13.2. Sampling error | |||
Not applicable for air transport data collection. |
|||
13.3. Non-sampling error | |||
The accuracy of the data depends on the data delivered by the airports. In case of doubt, the airport is contacted. |
|

|
|||
15.1. Comparability - geographical | |||
There are no problems of comparability for air transport data collection with a very high data comparability across contries due to the common legal basis. Comparisions of the data regarding passengers and freight/mail declared by partner reporting airports (so-called mirror checks) by Eurostat allow further the detection of possible inconsistencies which can be corrected if possible. |
|||
15.2. Comparability - over time | |||
As from 2002 the statistics on air transport are comparable over time, as they are collected following fully the provisions of the legal act - the Regulation 437/2003. Time series checks are regularly made to detect inconsistencies in the data. |
|||
15.3. Coherence - cross domain | |||
There are no cross-domain coherence checks so far. |
|||
15.4. Coherence - internal | |||
Data published by Eurostat and by the NSI are coherent since they use the same data as input. |
|
|||
The response burden is put on the airports. |
|
|||
17.1. Data revision - policy | |||
Before data are sent to Eurostat and before official release of the results on the Statbel-website, data are validated according the NSI rules and procedures. |
|||
17.2. Data revision - practice | |||
