- 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)

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

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.

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


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.


32


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:a)State Flightb) Instructional flyingc) Private flyingd) Business flyinge) Parachute and glider launch flightsf) Technical stopsg) Test flighth) Positioning flighti) Other non-commercial.


33


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

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
