Holding Pattern - AIXM Property Coding Checklist

The following table provided a complete overview of the AIXM 5 features/objects and properties relevant for the coding of holding pattern which will be published as part of an PANS-AIM defined AIP data set.

The table also gives an indication if the property is mandatory for an AIP data set and under which conditions.

Note

Currently, a Property Coding Checklist is only provided for some subjects. This are test pages for review, to see if such a checklist is useful. In case the feedback is accordingly a corresponding Property Coding Checklist may be created also for other subjects of the AIP data set.
