Taken together, the AIXM Conceptual Model and the AIXM XML Schema provide technical and semantic interoperability.
|
|
|
Main benefits of the AIXM Conceptual Model |
|
 |
Represent real world concepts as a theoretical construct which can be represented and understood by automated systems |
|
|
Provide a basis for logical data structures used during software implementation |
|
|
Achieve neutrality against applications and their local views of the data
|
|
|
Standardise the conceptual understanding of aeronautical data by all actors - "speak the same language" |
|
|
|
Main benefits of the AIXM XML Schema |
|
|
Improved safety: Reduced data inconsistencies, computer interpretable data means fewer errors for pilots and other aviation system users. |
|
|
Reduced costs: The AIXM model can be reused in software systems. By basing AIXM on industry standards, adopters can leverage existing commercial and open source tools. By enabling digital input and output, we can reduce data quality checking and data integration costs. |

AIXM 5 is based on:
|
|
ICAO Annex 15
|
|
|
Industry standards like ARINC and EUROCAE/RTCA specifications |
|
|
Other standards and best practices |
|
|
Real world aeronautical information publications
|
|
|
It also considers aspects that are not subject to formal requirements. Examples: route usage restrictions, declared distances from runway/taxiway intersections, airspace aggregations and fuel types. |
|
|
|
AIXM 5 has a number of key concepts:
|
|
A temporality model, including support for the temporary information contained in NOTAM |
|
|
Alignment with ISO standards for geospatial information, including the use of GML
|
|
|
Use of UML as conceptual schema language |
|
|
Support for the latest industry and ICAO requirements for aeronautical data including obstacles, terminal procedures and airport mapping databases
|
|
|
Modular and extensible to support current and future aeronautical information messaging requirements and additional data attributing requirements. |

AIXM 5 is intended to be a global standard for international exchange. One of the recommendations of the Global AIS Congress that took place in Madrid in June 2006 was for ICAO to adopt AIXM as the standard for aeronautical information exchange in digital format.
It is hoped that future related data standards will also leverage AIXM. Other candidate domains include:
|
|
Weather
|
|
|
Flight planning and operations |
|
|
Aerodrome operations |
|
|
Environmental information |
|
|
Air traffic management |
