Description
Attribute designator is added to DeicingArea to provide the possibility to identify more than one such area on the aerodrome.
Rationale for change
See https://aixmccb.atlassian.net/browse/AIXM-443
It was identified that more than one DeicingArea may exist on an aerodrome, which requires a clear distinction by providing a designator. Such designator is currently provided only with an annotation.
Therefore, it is proposed to add a new attribute designator of data type TextDesignatorType to address this missing data item. This will also align AIXM 5.2 with AMDB standard ED-99/DO-272.
Impact assessment
There is no impact on existing implementations as the current AIXM 5.1.(.1) data remains fully valid against AIXM 5.2.
When receiving data from AIXM 5.2 implementations, current AIXM 5.1(.1) systems will have to be able to map back the new attribute according to the mapping algorithm below.
Change Proposal details
In the UML model in the DeicingArea class:
- Add attribute:
- designator, data type = TextDesignatorType, definition = “The textual designator of the deicing area.”
The following UML class diagram shows the new attribute:
Mapping AIXM 5.1.1 to AIXM 5.2 (forward)
Not applicable
Mapping AIXM 5.2 to AIXM 5.1.1 (backward)
The following algorithm shall be applied:
[MAPC-02] For each DeicingArea
- Remove the designator element
- Add an annotation.Note associated with the owner class having
- purpose=“OTHER:BACKWARD_MAPPING”;
- LinguisticNote.note=”designator: <value of designator>
