Description
Additional attribute maxWingSpan is added to GuidanceLine.
Rationale for change
https://aixmccb.atlassian.net/browse/AIXM-479
It was identified that GuidanceLine was missing an attribute that could support wingspan limitations for the aircraft maneuvering among different airport movement areas using e.g. various guidance lines connecting the surfaces.
The new maxWingSpan attribute introduced in the GuidanceLine is added to cover these needs.
Impact assessment
There is no impact on existing implementations as the current AIXM 5.1.(.1) data remains fully valid against AIXM 5.2. No values are removed from this list.
When receiving data from AIXM 5.2 implementations, current AIXM 5.1(.1) systems will be able to map back the new values, as described in the mapping rules further in this document.
Change Proposal details
In the UML model, in the GuidanceLine feature:
- Add a new maxWingSpan attribute defined as “A limitation of aircraft’s wing span. It can be used to indicate the size of an aircraft that can maneuver along a guidance line.”, data type = ValDistanceType.
The following UML class diagram shows the additional attribute:
Mapping AIXM 5.1.1 to AIXM 5.2 (forward)
Not applicable
Mapping AIXM 5.2 to AIXM 5.1.1 (backward)
[MAPC-02] From the three backward mapping options applicable in this case, the first two (discard the value or use an extension) are straightforward and do not need any further details. The 3rd option (backward mapping into a Note) is detailed in order to provide a complete description of this case and its conversion option. The following mapping into Note algorithm is proposed:
- Remove the new attribute maxWingSpan.
- Add an annotation.Note associated with the owner class having
- purpose=“OTHER:BACKWARD_MAPPING”;
- translatedNote.LinguisticNote.note=”maxWingSpan:<value of maxWingSpan>”
