The AIXM scope is based on the ICAO requirements for provision by the Member States of the “data necessary for the safety, regularity and efficiency of international air navigation”. However, the specification goes beyond the strict ICAO Annex 15 requirements, by also taking into consideration existing industry standards (such as ARINC 424) and emerging data needs.
The Aeronautical Information Exchange Model (AIXM) is a specification divided into two components:
- A logical information model expressed in UML
- A data exchange format using XML Schema (XSD) technology
AIXM UML Model
The AIXM UML Model provides a formal description of the information managed by the Aeronautical Information Services (AIS). It is based on the ICAO Standards and Recommended Practices, on the content of the real world Aeronautical Information Publications (AIP) and on other relevant documents and industry standards, such as the ARINC 424 Specification.
AIXM XML Schemas
The AIXM XML Schemas are a data encoding specification for aeronautical data. They are an implementation of the AIXM UML Model as an XML (Extensible Markup Language) schema. Therefore, the XSD Schemas can be used to send aeronautical information to others in the form of XML encoded data, enabling systems to exchange aeronautical information.
