Role of models in AIMRole of models in AIM

Classical AIS

- publish documents

Document content and format is described by:

- ICAO Annex 15, Appendix 1 – AIP Content

- ICAO Annex 15, Appendix 6 – NOTAM format

- ICAO Annex 4, Aeronautical Charts

- FAA forms

SUP, NOTAM,

AIC

AIM System - manage data - publish traditional and new products - accurate and fast exchange

Data managed in the system is described by models:

- ARINC 424

- Aeronautical Information Exchange Model (AIXM)

- Electronic AIP (eAIP) Specification

- Airport Mapping Database (AMDB)

- Terrain and Obstacle Database

- New products…

• Streamline data management and product maintenance– Model aeronautical information as a whole– Create AIS products from a single data source– Ability to integrate workflow and configuration

• Role of data models– To represent real world concepts as a theoretical

construct which can be represented and understood by automated systems

– To standardise the conceptual understanding of aeronautical data by all actors - “speak the same language"

– To provide a basis for logical data structures used during the software implementation

– To provide basis for formal ‘contracts’ between interoperable systems – example: “use the same format"

ConclusionConclusion

• AIXM provides international standardization– Content model: UML class definitions for features,

attributes, data types, associations & business rules– Exchange format: XML/GML encoding

• Enables transition from AIS to AIM– New services and products (e.g., digital NOTAM,

NDBX)

• AIXM is flexible and extensible• AIXM working to satisfy industry requirements
