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

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’
