This section provides supporting material for the encoding of AMD features.

This includes the list of ED-99()/DO-272() features and how they map into the corresponding AIXM 5.1.1 features.

The encoding of features in AIXM 5.1.1 is further documented per feature.

titleLimitations

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

    requires meeting all Industry requirements. This may involve:

    • data constraints
    • data transformations
    • specific default data values
    • etc...

    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
