Description
The existing AngleIndication and DistanceIndication features become <<object>> classes and are renamed Angle and Distance respectively. As a consequence, relationships with PointReference, SegmentPoint, DesignatedPoint and SignificantPoint are modified/added/deleted. Additional vertical limitation attributes are added in the PointReference class.
Rationale for change
See https://aixmccb.atlassian.net/browse/AIXM-181
As explained in the “AIXM UML to XML Schema Mapping”, AIXM <<feature>> classes are fundamental in AIXM. They can correspond to concrete and tangible real-world objects or to abstract and conceptual items. AIXM Features have properties that can change in time. These properties are encapsulated into classes with stereotype <<object>>, which do not exist independently (outside of a feature).
In the current model, AngleIndication and DistanceIndication are declared as <<feature>>. The following UML class diagrams show their attributes and associations (except association with Note). As the two classes have similar associations, the AngleIndication and DistanceIndication are shown “overlapped”.
Considering their current relationships with PointReference and the SegmentLeg specialisations, the Angle/DistanceIndication exist only when they are used to locate the position of a start/end segment point or as trajectory limitations for a procedure leg. In these cases, they are de-facto “objects” (complex properties of the related features). The only exception is the association “locates DesignatedPoint”, which could theoretically allow to provide fix information for a point, independent from its use as segment point. However, this also has a significant limitation, as the AngleIndication and DistanceIndication are separated features, which cannot be combined to provide a “significant point fix” information. Further more, the circular association Angle/DistanceIndication → (fix) DesignatedPoint ← (locates) PointReference → (isBasedOn) Angle/DistanceIndication could be easily misused for illogical combinations of angle/distance referring to different points.
Many AIXM 5.1 users complain that creating a feature for each AngleIndication and DistanceIndication is an unnecessary complication because they are typically used for a single PointReference or SegmentLeg. In addition, their properties do not give any convenient set of identifying properties, which makes it difficult to select the correct one to use in a given context.
Therefore, it is proposed that AngleIndication and DistanceIndication are replaced with equivalent <<object>> classes, while the current model capabilities are preserved.
Also, the PointReference was missing the possibility to specify a minimum and a maximum usage level, which result from the combination of angle/distance indication and the level at which the navaid signal is available or authorised. These attributes are proposed to be added.
Impact assessment
[FWD_MAP_1:1] Data mapping is possible and no data loss occurs when data is exchanged from a system (A) that uses AIXM 5.1.1 for output towards a system (B) that uses AIXM 5.2 for input.
[BWD_MAP_LOSS] Data mapping is possible, but some data would be lost (or converted into Notes) when data is exchanged from a system (B) that uses AIXM 5.2 for output towards a system (A) that uses AIXM 5.1.1 for input.

Mapping AIXM 5.2 to AIXM 5.1.1 (backward)
