Description
“DER” (Departure End of Runway) is added to CodeRunwayPointRoleBaseType to cover the missing role.
Rationale for change
See https://aixmccb.atlassian.net/browse/AIXM-285
Based on the PANS-OPS provisions it was identified that “DER” is missing from CodeRunwayPointRoleBaseType and walkarounds need to be used to encode this role in support of SID procedures. It is proposed that “DER” is added to the list of values.
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 into OTHER:... values, as described in the mapping rules further in this document.
Change Proposal details
In the UML model:
- In data type CodeRunwayPointRoleBaseType add the following value:
- DER, type = string, definition = “Departure End of Runway”
The following UML class diagram shows the modified list of values.
Mapping AIXM 5.1.1 to AIXM 5.2 (forward)
[MAPC-01] The following data conversion algorithm is proposed for:
- For each RunwayCentrelinePoint that has role equal-to ‘OTHER:DER’:
- Replace ‘OTHER:DER’ with ‘DER’
Mapping AIXM 5.2 to AIXM 5.1.1 (backward)
[MAPC-01] The following data conversion algorithm is proposed for:
- For each RunwayCentrelinePoint that has role equal-to ‘DER’
- Replace ‘DER’ with ‘OTHER:DER’
