AIXM Model Overview
The figure below shows the main AIXM 5 classes used for the Designated Point concept:
Every DesignatedPoint must have a designator and a specified geographical position. In addtion a name and a type (e.g. 'ICAO', 'COORD', 'TERMINAL') may be defined.
Designated points with an ICAO 5 letter code used for defining ATS routes sould be recorded as type equal-to 'ICAO'.
The position of a DesignatedPoint may additionally be specified by an AngleIndication and/or a DistanceIndication, from an appropriate Navaid.
AIXM 5 also provides the possibility to encode points which are used in the context of defining terminal procedures. For this purpose several relationships can be established:
- AirportHeliport
The designated point designator is unique within all other designated points associated with the same aerodrome/heliport. Typically, such points are used for RNAV procedures at that aerodrome/heliport.

A change proposal (AIXM-402) for the next AIXM 5.2 version has been approved by the AIXM Change Control Board, which allows the addition of ICAO country code as an attribute. The coding guidelines provided here are aligned with forward/backward conversion rules contained in the AIXM-402 Change Proposal. |
