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
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

6
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

• What is a VOR?
• Are you a cartographer, pilot, flight inspector,
  frequency engineer, airspace officer, obstacle
  evaluator, facilities service technician?

Explaining AIXM 5

• Mission and Objectives

• Coverage of the AIXM 5 data model
• Scope of aeronautical information
• Emerging partner standards

11
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
Why is ISO19100 series important?

• Common foundation for domain model
• International concepts and terminology
• Common models temporality, geometry, metadata

Product Specifications (Exchange Messages)
Application Schema (Domain Model)
General Feature Models (Framework)
14
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

• 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

18
Key Concept Geometry and GML

• Geometric and cartographic calculations
• Label placement
• Distance between Navigation Aids
• Course and bearing
• Airspace penetrations
• Flight planning

19
Key Concept Geometry and GML

• ISO 19136 Geography Markup Language (GML)
• Vendor independent standard
• Based on XML
• Good industry adoption

20
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

21
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

22
An Example Navaid frequency change
Imagine that AML Navaid undergoes an upgrade that
changes its frequency from 112.0 MHz to 113.2 MHz
