Overview
This section considers the need for airports to exchange data with the air traffic management (ATM) network including local ATC and the Network Manager.
Actions
- Review Use case sope, complete also with data use cases from ATC flowing to Airports (NOTAMS, etc.) Scott Wilson 15.05.2023
- Migrate existing use cases into the ACRIS use case template into Confluence (copy the ACRIS Use Case Template underneath D2 - ATC (Core) page) Scott Wilson 15.05.2023
- Terminology: Provide a report on how many terms identified need to be defined and how many of these are existing in the ACRIS model. Provide update on a Friday meeting Scott Wilson 15.05.2023
- Scott needs access to ACRIS model
- Members to (peer) review D2 use cases before creating sub-pages 7/7/2023

AODB ID and ROTATION ID
These are the values, which allow us to link arrival and departure flights together. The objective is to have AODB ID as a unique number or string. The desired logic is like the one presented below:
| AODBID | ROTATIONID | CALLSIGN | |
|---|---|---|---|
| Arrival Flight | 1111 | 2222 | AAA123 |
| Departure Flight | 2222 | 1111 | AAA333 |
Unique identification
e.g. for AODB ID. Consider e.g.
- GUFI - The strategic target from ATC/Eurocontrol point of view. Not yet broadly and in any case implemented / available.
- IFPLID - Available for IFR flights within Europe and in concern of Eurocontrol.
- Local ATC ID - Available for IFR flights within Switzerland
- Local Airport ID - Created for local VFR flights that are not of ATC concern
VIA_*
An airport has the possibility to have the VIA information. However, FPL doesn't have that possibility.
Imagine that you have a flight from Alicante to Manchester via Lille. Your final destination will be Manchester, that means that you have to give border control resources to the departure passengers from Alicante. This is a legal requirement, but on the other side, you will have one FPL from Alicante to Lille and another FPL from Lille to Manchester. This is the reason for the via, you need to link that departure with a FPL with ADES different to the final destination.
Exchanging Information
Airport Transit View Message Exchange
Current method
At the moment, EUROCONTROL pulls files from airports. Each airport has its own server, file format, data format.
Future method
EUROCONTROL will make an API available for airports to push standardised messages/files (XML/JSON) to EUROCONTROL.
A standardisation of the file name is desirable. The structure could include the ICAO airport code and the date when the file was generated. Example: ICAO Code + Date (DD:MM:YYYY HH:MM:SS) -> EBBR_13032023162300
This approach will be tested as part of E-CRA (https://www.eurocontrol.int/news/new-eurocontrol-network-manager-programme-integrate-small-and-regional-airports-network).

- EUROCONTROL: Harmonisation of A-CDM milestone/timestamp abbreviations e.g. including those used by airports in their local systems.
- EUROCONTROL: FIXM extension for A-CDM or decide to use ACRIS
