                                      Purpose of AIM
                              Improve internal processes

• 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
    management

                             “data layer”
               Data modeling is important

• 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"

– Not possible for a computer to identify
  automatically which TWY is closed
   • NOTAM is intended to be read and understood by
     humans, not by machines;
   • unreliable to ask a computer to interpret the free text

• 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
