  1. Introduction to AIXM

  2. Topics • Criticality of AIS information • AIM – a “data centric” approach • Worldwide interoperability • AIXM mission • Related developments

  3. Aeronautical information criticality Data quality?

  4. Aeronautical Information Management bulk data upload data update State 3 AIP, charts, etc. NOTAM Data Service Provider services AIP AIP eAIP, iPIB Applications Regional database AIXM NOTAM Standards DATA AIXM State 2 AIP, charts, etc. State 1 NOTAM Data management AIP, charts, etc. NOTAM Data management ARO Briefing AFTN (low bandwidth) Surface mail

  5. Role of models in AIM AIP SUP, NOTAM, AIC AIM System - manage data - publish traditional and new products - accurate and fast exchange 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 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…

  6. 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 AIS Office Products Data management Product Creation Engines

  7. Purpose of AIM Improve external processes AIP AIP NOTAM NOTAM “data layer”

  8. 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"

  9. AIXM – the first versions AIP Sources

  10. AIXM - Internationalization Complete Data Model (Military/Civilian) Standards (ISO) Global Requirements

  11. AIXM 5 - Global Standard AIXM

  12. Mission • Based on global aeronautical data requirements • ICAO standards and practices • Industry requirements • Modular and extensible • Support current and future AIM information system requirements • Digital AIPs • Automated charting and publications • Integrated digital NOTAMs • Aerodrome Mapping Databases and applications • Situational displays • Etc.

  13. AIXM components Conceptual (content) Model Exchange format specification

  14. Aerodromes Airspace NAVAIDS & Fixes Scope EnRoute Airspace Route Terminal Fix Procedures Service Airport/Runway Airport/Runway • Routes • Procedures • Obstacles • Organizations & Services

  15. Temporal scope AIXM 3.3

  16. Why digital NOTAM • TWY closure • Today, published as NOTAM A0874/03 NOTAMN Q) EBBU/QMXLC/IV/M/A/000/999/5054N00429E005 A) EBBR B) 0308250500 C) 0310271600 E) TAXIWAYS OUTER 7 AND E6 CLSD • 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 field <OK for computers> <not OK for computers>

  17. AMDB/xNOTAM Study Digital NOTAM Digital NOTAM Decoder “static” database • Gap Analysis ED-99A – AIXM and Prototype AIXM 5 schema • Validation of AIXM temporal model • Validation of results in real scenario in flight simulator • Use AIXM 5 message to announce temporary change • Visualise change information on cockpit display

  18. WG-76/SC-206 • Industry requirements for AIS Data Link • EUROCAE WG 76 jointly with • RTCA SC 206 • Objective • Identify AIS and MET Data-Link services that are envisaged to be implemented within the next decade in both Europe and USA • Develop the Operational Service and Environment Definition (OSED) document, Safety and Performance Requirements (SPR) and Interoperability Requirements (INTEROP)

  19. ARINC NDBX AIXM(XML)

  20. Conclusion Ground upload AIS Data Link services AIP AIP NOTAM NOTAM SC-206 NDBX, ARINC - 816 Service Provider AIXM AIXM

  21. Conclusion • 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
