National data sources 7 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

National data sources – the early days 9 Statistics Portugal promoted close contact with: Airports central administration and 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)

Table A1 - Flight stage dataset Scope: commercial aviation Periodicity: monthly basis Variables: 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 type Values: passengers, freight and mail on board, commercial air flights and passenger seats available Information requirements « 15

Table B1 - On flight origin / destination dataset Scope: commercial aviation Periodicity: monthly basis Variables: 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 « 17

Some of the checks produced by Eurostat: Consistency over time/Passengers Consistency over time/Freight and mail Consistency over time/Commercial air flights Comparison between arrivals and departures Interdataset checks/Passengers Interdataset checks/Freight and mail Seats available check Mirror checks Missing routes check Data quality checks « 24

Consistency over time - Passengers Consistency over time - Freight and mail Consistency over time - Commercial air flights Applied on A1 and B1 Different thresholds for different magnitudes - Checks not problematic Data quality checks « 25

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 islands Data quality checks « 26

Data quality checks « 28 Interdataset checks/Passengers Interdataset checks/Freight and mail Applied on A1 C1 B1 C1 Thresholds are adequate - Efficient codification good coherence!

Data quality checks « 29 Seats available check /passengers Aircraft 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 movement -An aircraft movement performed for remuneration or for hire. -Includes: - commercial air service movements - commercial general aviation operations. Common use of same definitions « 30 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 31 Source: Transport glossary (Eurostat/ITF/UNECE)

General aviation operations – commercial All 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 taxi b) Photographic c) Sightseeing trips d) Advertising e) Agricultural/crop spraying f) Medical/air ambulance trips g) Other commercial. Common use of same definitions « 32 Source: Transport glossary (Eurostat/ITF/UNECE)

General aviation operations – non-commercial All 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: a)State Flight b) Instructional flying c) Private flying d) Business flying e) Parachute and glider launch flights f) Technical stops g) Test flight h) Positioning flight i) Other non-commercial.

Transformation of OD data to flight stage data Airports Aircrafts Transport operators Need to ensure that airport database is understandable and convertible Major difficulties « 34

Systematic data codification Airports Aircrafts Transport operators Requires IT support, computer programming Major difficulties « 35

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 « 36 Major difficulties

Aircraft seats available, example of reference table « 37 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 « 38

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 « 39

New information needs, Commission and AESA: Data with breakdown by type of aircraft (aircraft- km, number of cycles) True origin / destination, number of transfers,... But... One step at a time! For the future « 40
