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

Aeronautical Information is Critical Data quality?

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

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

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

Why is ISO19100 Series Important? Common foundation for domain model –International concepts and terminology –Common models: temporality, geometry, metadata… General Feature Models (Framework) Application Schema (Domain Model) Product Specifications (Exchange Messages)

Value of ISO 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) 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 SDAT 5.7 Release New Features >> Create traffic collections based on a sector number. (Flights flown through specified sector(s)) … SDAT 5.7 Release New Features >> Create traffic collections based on a sector number. (Flights flown through specified sector(s)) … 20L RIGHT … 20L RIGHT … Web Page HTML XML Document

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 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 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
