What’s New with AIXM 5
Explaining AIXM 5
• Mission and Objectives
• Coverage of the AIXM 5 data model– Scope of aeronautical information– Emerging “partner” standards
• Building blocks of AIXM 5– International standards– Engineering practices
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
• Decommissioning– Closing a runway
• Temporary changes– Declared distance changes
during day and night– Partial runway closures– Field conditions caused by
weather
XXXXXXXX
Aeronautical Information is complex
• What is a VOR?– Are you a cartographer, pilot, flight inspector,
frequency engineer, airspace officer, obstacle evaluator, facilities service technician?
Located at an Airport
Used on a Departure Procedure
Used on an enroute Route
Provides angle indication for a fix
Has coverage areas
Has owner/operator

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

• Visual language for capturing relationships, behavior and high-level ideas
• Originally intended for Software Engineering
• Today also used for– Business process modeling
– Data modeling
– Requirements modeling
– Others…
Extensible Markup Language (XML)
• XML – Extensible Markup Language– Have you looked at
whatis underneath a webpage?
– XML has a similar look to HTML
• Computer readable– Electronic exchange– Vendor supported

Key Concept: Geometry and GML
• Geometry important property of aeronautical information– Airspace polygons– Airport Reference
Points– Navaid location
Key Concept: Geometry and GML
• Geometric and cartographic calculations– Label placement– Distance between
Navigation Aids– Course and bearing– Airspace penetrations– Flight planning
Key Concept: Geometry and GML
• 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 upgrade3. Perform the upgrade4. Start AML in test mode to evaluate
change
An Example: Navaid frequency changeImagine that AML Navaid undergoes an upgrade that changes its frequency from 112.0 MHz to 113.2 MHz…
