Purpose and Scope
These pages contain the AIXM coding guidelines for the minimum and conditional data items of the AIP data set for the Radio navigation aid subject as defined in PANS-AIM.
AIP context
In an AIP, corresponding Radio navigation aid information may be published in the following sections:
- GEN 2.5 List of radio navigation aids
- ENR 4.1 Radio navigation aids — en-route
- AD 2.19/AD 3.18 Radio navigation and landing aids
AIXM Model Overview
Coding Example
The figure below shows a simple example of a collocated "VOR/DME" with the designator "BOZ" and the name "BERG-OP-ZEE".
It consists of two navaid equipments, a VOR and a DME. Both have the designator "BOZ".
Both have the same defined magnetic variation and are operational H24.
The VOR and the DME are located at the same position. Only the DME has a defined elevation of "30 meters".
Also, the Navaid has a location which, as there is no dislocation, is the same as the one for the navaid equipments.
The VOR does have a frequency, whereas for the DME a corresponding channel is defined.
The VOR in addition has a defined declination.
Also, the Coverage of the VOR and/or DME may be provided (note that this information is not required for the minimum/conditional AIP data set).
The figures below show the AIXM 5.1 encoding of some of the data described above.
The figure below shows the encoding of one of the referenced navaidEquipment of the figure above, viz. the VOR "DON"
The location is the same as for the Navaid.
Coding examples can also be found in the DONLON AIXM 5.1.1 AIP data set file:
