What’s New with AIXM 5

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

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

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

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

Aeronautical Information is Complex Located at an Airport Used on an enroute Route Has coverage areas Used on a Departure Procedure Provides angle indication for a fix Has owner/operator • 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 Critical Data quality?

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

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

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

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

Unified Modeling Language (UML)

Extensible Markup Language (XML) Web Page HTML • XML – Extensible Markup Language – Have you looked at what is underneath a web page? – XML has a similar look to HTML <h 2><a href="sdat 2/html/download. htm"> SDAT 5. 7 Release</a></h 2> <h 3 class="byline">New Features >></h 3> <p> <ul> <li>Create traffic collections based on a sector number. (Flights flown through specified sector(s))</li> … <Runway. Direction> <Designator>20 L</Designator> • Computer readable – Electronic exchange – Vendor supported XML Document <VFRPattern>RIGHT</VFRPattern> </Runway. Direction> …

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

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

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

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

An Example: Navaid Frequency Change Imagine that AML Navaid undergoes an upgrade that changes its frequency from 112 MHz to 113. 2 MHz… 1. Schedule permanent change to coincide with AIRAC update cycle 2. Shutdown AML before the upgrade 3. Perform the upgrade 4. Start AML in test mode to evaluate change

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…
