Data Coding GuideLines

The complexities inherent to the encoding of aeronautical information and lack of harmonised approaches may lead to differences in the data. This in turn may lead to barriers to be surmounted when exploiting digital data in a network context.

To promote the harmonisation of digital data  there is a need for common data coding guidelines. When supported by precise and interpretable business rules, it is then possible to verify the compliance of digital data (e.g. AIXM data sets) versus the common data coding guidelines.

This will then result in more harmonised digital data to the benefit of the consumers of information.

In the context of this AMD supporting material the breakdown of data coding guidelines is as follows:

  • the common data coding guidelines applicable to any AIXM 5.1 encoded data set
  • the specific data coding guidelines applicable for: 
    • AMD sets encoded in AIXM 5.1 (), currently (July 2023) unspecified
    • AMDB as specified in ED-99(), ED-119(), also known as the functional and geometrical constraints
