  1. What’s New with AIXM 5

  2. Building blocks of AIXM 5 • International standards • Engineering practices • Coverage of the AIXM 5 data model • Scope of aeronautical information • Emerging “partner” standards Explaining AIXM 5 • Mission and Objectives

  3. Mission and Objectives • Standards-based data model and exchange format that can satisfy the aeronautical information exchange requirements for current and future aeronautical information applications • Based on global aeronautical data requirements • ICAO standards and practices • Industry requirements • Support current and future AIM information system requirements • Digital Aeronautical Information Publications (AIPs) • Automated charting and publications • Integrated digital NOTAMs • Aerodrome Mapping Databases and applications • Situational displays

  4. Aeronautical Information is Geospatial • Locations • Airspace boundaries • Airport layouts • Routes • Cartography • Bearings

  5. Commissioning A new runway Decommissioning Closing a runway Temporary changes Declared distance changes during day and night Partial runway closures Field conditions caused by weather Aeronautical Information Changes in Time XXXXXXXX

  6. What is a VOR? Are you a cartographer, pilot, flight inspector, signal processing engineer, airspace officer, obstacle evaluator, facilities service technician? The information you need depends on your point-of-view Aeronautical Information is Complex Located at an Airport Has coverage areas Used on an enroute Route Used on a Departure Procedure Has owner/operator Provides angle indication for a fix

  7. Aeronautical Information is Critical Data quality?

  8. bulk data upload data update State 3 AIP, charts, etc. NOTAM Data Service Provider services AIP AIP eAIP, iPIB Applications Regional database NOTAM DATA We Need Aeronautical Information Integrity“Right Information, Right Place, Right Time” State 2 AIP, charts, etc. State 1 NOTAM Data management AIP, charts, etc. NOTAM Data management ARO Briefing AFTN (low bandwidth) Surface mail

  9. Aeronautical Information Management and AIXM AIP AIP NOTAM NOTAM “data layer”

  10. Building blocks of AIXM 5 • International standards • Engineering practices Explaining AIXM 5 • Mission and Objectives • Coverage of the AIXM 5 data model • Scope of aeronautical information • Emerging “partner” standards

  11. Geography and Geometry ISO 19136 Geography Markup Language Complexity ISO 19100 series UML, XML, Extensibility ISO 19108 Temporal Permanent and Temporary changes Temporality Universal Unique Identification (UUID) ISO 19115 Metadata Integrity Criticality XML Computer – Computer Exchange Engineering AIXM

  12. AIXM is Based on International Standards Aeronautical Information Exchange Model (AIXM) ISO 19107 Spatial Extensible Markup Language (XML) ISO 19108 Temporal ISO 19136 Geography Markup Language (GML) ISO 19115 Metadata Universal Markup Language (UML) Exchange standards Conceptual standards

  13. Value of ISO 19100 Standards • Internationally developed standards for expressing geographical data • Features - Airports, Runways, Airspace • Metadata - Data Originator, Status, Published Date • Temporality - Start and end dates • Geometry - Point, Line, Polygon • Helps us organize information for the aeronautical domain • Well-established • Geography Markup Language (GML) • Widely adopted and implemented by vendors and governments

  14. Unified Modeling Language (UML)

  15. XML – Extensible Markup Language Have you looked at what is underneath a web page? XML has a similar look to HTML Computer readable Electronic exchange Vendor supported Extensible Markup Language (XML) Web Page HTML <h2><a href="sdat2/html/download.htm"> SDAT 5.7 Release</a></h2> <h3 class="byline">New Features >></h3> <p> <ul> <li>Create traffic collections based on a sector number. (Flights flown through specified sector(s))</li> … XML Document <RunwayDirection> <Designator>20L</Designator> <VFRPattern>RIGHT</VFRPattern> </RunwayDirection> …

  16. Geometry - important property of aeronautical information Airspace polygons Airport Reference Points Navaid location Key Concept: Geometry and GML

  17. Geometric and cartographic calculations Label placement Distance between Navigation Aids Course and bearing Airspace penetrations Flight planning Key Concept: Geometry and GML (cont’d)

  18. ISO 19136 Geography Markup Language (GML) Vendor independent standard Based on XML Good industry adoption Key Concept: Geometry and GML (cont’d)

  19. Temporality Model • Definition • A model that incorporates the concept of time • Key assertions • All features are temporal with start of life and end of life • Example: A new air traffic control sector • All features change over time • Example: A VOR is out of service for a day • AIXM Temporality Model • Relates features to the time extent in which they are valid • Provides various means to describe the time extent

  20. An Example: Navaid Frequency Change Imagine that AML Navaid undergoes an upgrade that changes its frequency from 112 MHz to 113.2 MHz… • Schedule permanent change to coincide with AIRAC update cycle • Shutdown AML before the upgrade • Perform the upgrade • Start AML in test mode to evaluate change

  21. An Example: Navaid Frequency Change (cont’d) Imagine that AML Navaid undergoes an upgrade that changes its frequency from 112.0 MHz to 113.2 MHz…

  22. Building blocks of AIXM 5 • International standards • Engineering practices Explaining AIXM 5 • Mission and Objectives • Coverage of the AIXM 5 data model • Scope of aeronautical information • Emerging “partner” standards

  23. AIXM Coverage and Related Standards AIXM Core • Based on same ISO 19100 framework • Ensures consistency • Reduces implementation complexity • Reduces integration complexity AIXM Core AIP Data FlightPlans Others… AMDB &AirMAT NOTAM Data Obstacles WXXM

  24. Aerodrome/Heliport Airspace Holding Navaids and Points Obstacles Organizations Procedures Refueling Aerial Routes Services Surveillance Shared Components Geometry Notes Time Management Aircraft AIXM Coverage
