AIXM 5 Development Status

AIXM – the first versions Sources AIP AIXM is a standard for aeronautical information dissemination that has been based on: ICAO Annex 15 “data to support international air navigation” Industry standards like ARINC 424 (for encoding terminal procedures) Other standards and best practices Real world aeronautical information publications It also took into consideration aspects that are not subject to formal requirements. Examples: route usage restrictions, declared distances from runway/taxiway intersections, airspace aggregations, fuel types, etc. AICM (the conceptual part of AIXM) - Started by Eurocontrol in 1996 AIXM – started in 1997 First attempt “SQL based” Move to XML in 1999 EAD operational since 2003 – All European States are expected to have joined the EAD by end 2008

AIXM - Internationalization Complete Data Model (Military/Civilian) Global Requirements Standards (ISO) The internationalization of AIXM really began in 2003 after the release of version 3.3. Set-up of the AIXM Change Control Board (ACCB) with international participation (States and industry) The United States Federal Aviation Administration, United States National Geospatial Intelligence Agency and EUROCONTROL began to collaborate on expanding AIXM to cover global civilian and military aviation needs. Major early activities included assessing AIXM model coverage and updating lists of values. In SEP 2005 AIXM 4.5 was released. This was the first release that incorporated suggestions from the international community and was a good test of consensus based configuration management.

AIXM 5 - Global Standard AIXM We think the future of AIXM as the global standard for aeronautical data is very promising. States outside Europe, such as Japan, Canada, United States have decided to base their new AIM systems on AIXM. The Global AIS Congress, which took place in June 2007 and gathered representatives from more than 90 States world-wide, has adopted a number of recommendations. The first one asks: “ICAO adopt the AICM/AIXM as the standard aeronautical information conceptual model and the standard aeronautical information exchange model, and develop appropriate means of compliance, and global mechanisms to manage and develop the AICM/AIXM” In order to match the expectations of the global AIS community, an AIXM Design Team, organised in cooperation between EUROCONTROL and FAA, with the support of the international community, is developing the next AIXM version 5. This shall fully satisfy the global AIM needs.

Mission Based on global aeronautical data requirements ICAO standards and practices Industry requirements Modular and extensible Support current and future AIM information system requirements Digital AIPs Automated charting and publications Integrated digital NOTAMs Aerodrome Mapping Databases and applications Situational displays Etc. The goal for AIXM 5 is to provide an extensible, modular aeronautical information exchange standard that can be used to satisfy information exchange requirements for current and future aeronautical information applications. These applications include: Automated production of Aeronautical Information Publications (AIPs) Automated aeronautical chart creation and publication systems Integrated NOTAMs (e.g., xNOTAM) Aerodrome Mapping Databases (AMDBs) and related applications Electronic Flight Bag data requirements Cockpit situational displays and Flight Management System (FMS) data requirement

AIXM components Conceptual (content) Model Exchange format specification AIXM support AIM in two ways: The AIXM conceptual model describes the features in the aeronautical domain and can be used as the logical basis for AIM databases. Does this mean that your AIS database must copy the AIXM UML model? No, but the class definitions are derived from ICAO and industry requirements so your system should have similar aeronautical features and properties. By ensuring that your systems can map to the conceptual model, you are making it easier for your system to communicate using AIXM. The AIXM XML Schema is an exchange format specification for aeronautical data, which can be used to electronically transmit aeronautical data to others. It is positioned as an international standard for aeronautical data exchange between systems. In version 3 and 4, the conceptual model was using entity-relationship methodology. This has now been replaced by UML in version 5. The encoding was always based on XML, but in version 5 it also becomes compliant with the Geography Markup Language (GML).

Timeline AIXM 3.3

AIXM 5 RC 1 First draft UML model and XML schema Starting from AIXM 4.5 Still missing many features and attributes that are necessary in order to support digital NOTAMs

Timeline AIXM 3.3

AIXM 5 RC 2 Support for Airport Mapping Database (AMDB) Obstacle model -> Vertical Structures model Full compliance with the Geography Markup Language (ISO 19136) XML Schema Refinement of the Temporality model Punctual corrections and extensions following feedback from the stakeholder community

Timeline AIXM 3.3

AIXM 5 RC 3 Objectives model for Aerial Refuelling Routes model for Military Training Routes “Digital NOTAM” message format revision of the Service model ? rules for AIXM application schemas
