AIXM is the backbone of EAD representing both the data model the static data (SDO) is based upon and the exchange means for the aeronautical data. The current version of AIXM implemented in EAD is 4.5.
The newest version released in 2010 by the AIXM Development Team is AIXM 5.1. This version is the baseline that will progressively be implemented in EAD, in order to align EAD to the European Commission (EU) Regulation 73/2010 (Aeronautical Data Quality - ADQ), to the ICAO SARPS provisions for electronic terrain and obstacle data (eTOD) and to the Digital NOTAM.
AIXM Implementation in EAD
The EAD is currently undertaking the development process of implementing AIXM 5.1 in its SDO and INO subsystems, while AIP Tool and Charting tool will also be enhanced at a later stage in the same direction.
The key aspect that EAD takes into account is the parallel support of the Clients operating under both AIXM 4.5 and AIXM 5.1 environments. This means that EAD will continue to maintain the current SDO whilst progressively deploying the AIXM 5.1.
AIXM 5.1 Specification
The specifications required for the implementation of AIXM 5.1 in EAD have been finalized for Phase 1. They comprise:
- Component Overview
- SDO (AIXM 4.5) / SDD (AIXM 5.1) Interoperability Concept
- SDD (AIXM 5.1) User Requirements
- User Interface Design Definition - for the development of the HMI
- Software Architecture
- EAD AIXM 5.1 Temporality
- Slot / Workflow Management Concept
- AIXM 4.5 to AIXM 5.1 Mapping
The EAD Specification is based on the AIXM 5.1 documentation published on www.aixm.aero (AIXM 5.1 Temporality, Use of GML for Aviation Data, etc.)
