    Belgrade, November 27, 2012TKEY CHALLENGES IN AIR TRANSPORT STATISTICSTHE PORTUGUESE EXPERIENCE

  • Portugal: - member of the EU since 1986 - population: 10,6 million*

  • *

  • REGULATION (EC) No 437/2003 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCILof 27 February 2003on statistical returns in respect of the carriage of passengers, freight and mail by air

    Information requirements*

  • COMMISSION REGULATION (EC) No 1358/2003implementing Regulation (EC) No 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 and amending Annexes I and II thereto

    Information requirements*

  • COMMISSION REGULATION (EC) No 546/2005of 8 April 2005adapting Regulation (EC) No 437/2003 of the European Parliament and of the Council as regards the allocation of reporting-country codes and amending Commission Regulation (EC) No 1358/2003 as regards the updating of the list of Community airports

    COMMISSION REGULATION (EC) No 158/2007of 16 February 2007amending Commission Regulation (EC) No 1358/2003 as regards the list of Community airportsInformation requirements*

  • National data sources *Airport central administration National authority for aviation Collects data from the Airport Central Administration but also from the smaller airports, especially in some Islands (Azores) where the Regional Government is the administrator Manages the main airports in the Mainland and Islands

  • Data supply chain*Airline 1Airline nAirport 1Airport nStatisticsPortugalAirports central administration National authority for aviation Press releasesPublicationsOn line indicators

  • National data sources the early days *Statistics Portugal promoted close contact with:

    Airports central administrationand National authority for aviation

    - In order to achieve high involvement and determination to adapt their computer systems and harmonize nomenclatures- So that all movements are registered (some flaws were detected)

  • ICAO country identifier code

    Passengers *Direct transit passengersSource: Eurostat

  • ICAO - The International Civil Aviation OrganizationICAO country code document 7910

    2-letter codeConcatenation of: First digit - the ICAO Aeronautical fixed service area codes Second digit - ICAO country identifier codes

  • Table A1 - Flight stage dataset

    Scope: commercial aviationPeriodicity: monthly basisVariables: flight stage data registered for airport-to-airport routes broken down by arrivals/departures, scheduled/non scheduled, passenger service/ all-freight and mail service, airline information and aircraft typeValues: passengers, freight and mail on board, commercial air flights and passenger seats availableInformation requirements*

  • Table A1 - Flight stage dataset

    Information requirements*

  • Table B1 - On flight origin / destination dataset

    Scope: commercial aviationPeriodicity: monthly basisVariables: 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. Values: passengers carried and freight and mail loaded or unloaded

    Information requirements*

  • Table B1 - On flight origin / destination dataset

    Information requirements*

  • Table C1 - Airport dataset

    Scope: commercial aviation + General aviationPeriodicity: annual (at least)Variables: airport data registered for declaring airports, and broken down by airline information Values: total passengers carried, total direct transit passengers , total freight and mail loaded or unloaded, total commercial aircraft movements and aircraft movements

    Information requirements*

  • Table C1 - Airport dataset (1)

    Information requirements*

  • Table C1 - Airport dataset (2), if available

    Information requirements*

  • Exclusions

    Exclusion of A1 and B1: Airports handling more than 15 000 and less than 150 000 passengers per year report only C1 (airport dataset) (category 1)

    Total exclusion: Airports handling less than 15 000 passengers units annually (category 0)Information requirements*

  • Categories and exclusions in PortugalInformation requirements*

  • Some of the checks produced by Eurostat:

    Consistency over time/PassengersConsistency over time/Freight and mailConsistency over time/Commercial air flightsComparison between arrivals and departuresInterdataset checks/PassengersInterdataset checks/Freight and mailSeats available checkMirror checksMissing routes checkData quality checks*

  • Consistency over time - PassengersConsistency over time - Freight and mailConsistency over time - Commercial air flights

    Applied on A1 and B1Different thresholds for different magnitudes

    - Checks not problematicData quality checks*

  • Comparison between arrivals and departures

    Applied on A1 and B1 only to passengers

    Thresholds are tight

    - Checks are a problem, due to population flows and alternative means of transport (ferry) between islandsData quality checks*

  • Data quality checks*

  • Data quality checks*Interdataset checks/PassengersInterdataset checks/Freight and mail

    Applied on A1 C1B1 C1Thresholds are adequate

    - Efficient codification good coherence!

  • Data quality checks*Seats available check /passengersAircraft profile tables - have the average capacity (seats available) and (often) the maximum capacity; Problems: - In some short/medium distance flights with large demand, the real capacity of the aircraft can be adjusted: less fuel and cargo capacity provide more offer (these cases must be identified in the database and corrected)- Aircrafts adapted with more seats

  • Commercial aircraft movementAn aircraft movement performed for remuneration or for hire.Includes: commercial air service movements commercial general aviation operations.

    Common use of same definitions*Source: Transport glossary (Eurostat/ITF/UNECE)

  • Commercial air service

    An air transport flight or series of flights for the public transport of passengers and/or freight and mail, for remuneration or for hire.The air service may be either scheduled or non-scheduled.

    Common use of same definitions*Source: Transport glossary (Eurostat/ITF/UNECE)

  • General aviation operations commercialAll commercial civil aviation operations other than scheduled air services and non-scheduled air transport operations for remuneration or hire. The main categories of commercial general aviation are as follows:a) Air taxib) Photographicc) Sightseeing tripsd) Advertisinge) Agricultural/crop sprayingf) Medical/air ambulance tripsg) Other commercial.

  • General aviation operations non-commercialAll non-commercial civil aviation operations other than scheduled air services and non-scheduled air transport operations for remuneration or hire. The main categories of non-commercial general aviation are as follows:State Flightb) Instructional flyingc) Private flyingd) Business flyinge) Parachute and glider launch flightsf) Technical stopsg) Test flighth) Positioning flighti) Other non-commercial.Common use of same definitions*Source: Transport glossary (Eurostat/ITF/UNECE)

  • Transformation of OD data to flight stage dataAirportsAircraftsTransport operators

    Need to ensure that airport database is understandable and convertibleMajor difficulties*

  • Systematic data codification

    AirportsAircraftsTransport operators

    Requires IT support, computer programmingMajor difficulties*

  • Assess the seats offered

    Tables available have average capacity

    Aircrafts often have higher capacity (seats added to the initial construction layout) which may lead to distorted occupancy rates

    *Major difficulties

  • Aircraft seats available, example of reference table*Major difficulties

  • Keeping high involvement from airport administrations in order to: - respect datelines - have mutual trust and eliminate any doubts about safety procedures with confidential data

    For the future*

  • Keeping high involvement from national authority in order to: - have help understanding the air transport sector dynamic (companies,, ...) - get support on validation whenever may be necessary (effects of the bad weather, ...)For the future*

  • New information needs, Commission and AESA:
