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, signal

processing engineer, airspace officer, obstacle evaluator, facilities service technician?

– The information you need depends on your point-of-view

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

what is underneath a web page?

– 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 (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 upgrade3. Perform the upgrade4. 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…
