AICM/AIXM Concept introduction

• Show overall scope and connectivity of the

concept area

• Provide a concrete example of the

AICM/AIXM Concept – Identify some key properties but not all properties of

the concept area.

– Identify some key relationships but not all

relationships in the concept area

Summary

• NAVAID and Points Domain used to model “SignificantPoints” like NAVAIDs and Fixes

– VOR, TACAN, DME

– ILS, MLS

– Fixes

• Distance and Angle Indications can be used to define therelative position of two significant points

• Significant points are referenced at airports, on runways, inroutes and in airspace

• Operating hours are specified using a Time Table
