This section:

• includes the correspondences between elements in the different models that cover the needs of aerodrome mappings
• elaborates on the data encoding of AMD features and properties in accordance with revised ICAO Annex 15 and new PANS-AIM (ICAO Doc 10066), applicable European regulations and industry standards e.g. EUROCAE ER-009
• provides examples of AIXM 5.1.1. encoding

Limitations

The supporting material alone will not guarantee that an ED-99/DO-272 compliant Aerodrome Mapping Database is created. This can only be done by applying

• the data product specification rules and
• the complete functional and geometrical constraints

within ED-99/DO-272 and its normative encoding found in ED-119/DO-291.

In addition, where calculations or geometrical mergings are required, visual verification of the result will be required.

In some cases, additional steps are required by the implementer. For example:

• AIXM 5.1.1 allows the use of the geometrical curves and geodesics. ED-99/DO-272 only allows line-strings. Therefore the curve will need to be transformed into a line-string. Details on such transformations are out of the scope of this site.
• The AMDB Default values will need to be added to the AMDB where the AIXM 5.1.1 data is missing elements that are mandatory in AMDB.
