A radio navigation aid used in defining an ATS route, the flight path of an aircraft or for other navigation or ATS purposes. [FIXM] The coded designator of a navaid is not always sufficient for unambiguously referring to that feature: The en-route navaids (VOR, DME, NDB) designator is supposed to be unique (according to ICAO Annex 11) within 600 NM. This means that these designators are not unique world-wide. For airport navaids, there is no limitation. The combinations of fields that would make the references unique are designator + position + navaid service type. This FIXM class adds two optional properties 'position' and 'navaidServiceType' which may be used as a complement to the 'designator' information in order to remove any ambiguity on the coded designator.

Notes:

Provides an optional mechanism enabling FIXM aeronautical fields to be supplemented with references to AIXM features. This field should be considered functionally equivalent to the xlink:href field used in AIXM to reference features. [FIXM]

Element	Source Role	Target Role
«XSDcomplexType» GeographicalPosition Class	Name:	Name: position The values of latitude and longitude that define the position of the Navaid on the surface of the Earth with respect to a reference datum. [specialised from ICAO Doc 9881] This optional field may be used to achieve unambiguous reference to the navaid. The combinations of fields that would make the reference unique are name + position + navaid service type.

NavaidServiceType Enumeration	Name:	Name: navaidServiceType Type of the navaid service. [AIXM 5.1] This optional field may be used as a complement of the designator in order to achieve unambiguous reference to the navaid. The combinations of fields that would make the reference unique are designator + position + navaid service type.
