In AIXM 5.1.1, SATVOICE number, and any navigation, RCP and RSP specification(s) limitations can notcannot be encoded, except by using a Note. |
AIXM does not provide a direct relaionship relationship between Unit and RouteSegment class.
The concerned Unit has to shall be encoded independently. According to the PANS-AIM Appendix 1 (Aeronautical Data Catalogue), at least the name shall be provided.
In addition, a Service provided by the Unit has to shall be encoded. The Service class has several specialised classes that have an association to a RoutePortion, i.e. as there is no direct relationship to RouteSegment correspdoning corresponding RoutePortion has to be encoded. One or more of this these services may be provided for the same RoutePortion.
...
The type of service provided may be defined by the attribute Service,.type, or it may be included in the Service.name, or it may be included in the Unit.name.

Which of the 3 options shall be layed laid down as coding rule? |
The operation channel is encoded using the RadioCommunicationChannel class. The attribute frequencyTransmission will carry the corresponding value and uom. The RadioCommunicationChannel has to be referenced by the adequate Service.
According to the PANS-AIM Appendix 1 (Aeronautical Data Catalogue) a specified code used for data link logon to the controlling ATS unit shall be provided if applicable.
...
However, via the ContactInformation class related to the Service class, corresponding attributes of the OnlineContact class may be used to encode that information. The code list for the network attribute contains a value 'ACARS'; which is defined as
...
The linkage and protocol attribute may then be used to define the details about the logon address.
The figure below show shows how the information about the controlling unit is published in an AIP:
