3. Aeronautical Information Exchange Model - I • AIXM 5.1 • UML model, XML schema released since Feb 2010 • Currently in implementation • Guidance • Business rules • Purpose: capture relevant AIXM 5.1 business rules from existing AICM 4.5 rules, ICAO Annexes 10/11/14/15, ICAO PANS-OPS, ARINC 424-19…and standardise their wording & encoding using Semantics of Business Vocabulary and Rules (SBVR) and ISO Schematron • Maturity: Available for public review – likely to evolve over time to capture the feedback from AIXM stakeholders. • See https://extranet.eurocontrol.int/http://prisme-oas.hq.corp.eurocontrol.int/aixmwiki_public/bin/view/Main/AIXM_Business_Rules • Temporality Model • Purpose: Describe the temporality model implemented in AIXM 5.1 in order to satisfy the AIS temporal requirements – support of digital NOTAM in particular (not possible with AIXM4.5). • Maturity: v1.0 released • See http://www.aixm.aero/gallery/content/public/AIXM51/AIXM%20Temporality%201.0.pdf • GML Profile • Purpose: GML is a mature geometrical/geographical data encoding standard and that was the main reason to use it for AIXM. The role of the profile is to guide implementations in the aviation domain. There is nothing that is invented on top of GML, just explanations how it can be used for the encoding of aviation specific data. • Maturity: Still in development, no blocking issues so far. Industry involvement mainly through OGC - Aviation Domain Working Group. • See http://external.opengeospatial.org/twiki_public/pub/AviationDWG/GMLGuidelinesForAIXM/REF_Use_of_GML_in_aeronautical_data_-_Discussion_Paper_DRAFT_3.pdf AIS-AIMSG-#4

4. Aeronautical Information Exchange Model - II • Use of xlink:href and UUID • Purpose: To provide technical details with regard to the use of Universal Unique Identifiers (UUID) for aeronautical features and encoding of associations between features using the xlink standard • Maturity: v1.0 released • See http://www.aixm.aero/gallery/content/public/AIXM51/AIXM_Feature_Identification_and_Reference-1.0.pdf • Meta-data • Purpose: Enable the encoding of information related to the quality, traceability, etc. of an aeronautical data set or feature, to detail the user requirements for metadata in the aviation domain (main sources: ICAO, ADQ, INSPIRE) and to provide guidance on how to map these requirements into an ISO 19115 Metadata Profile. • Maturity: The metadata profile is available as an official OGC Discussion Paper. With the objective to promote it to OGC Best practice / Guidance Material when mature enough. • See http://portal.opengeospatial.org/modules/admin/license_agreement.php?suppressHeaders=0&access_license_id=3&target=http://portal.opengeospatial.org/files/?artifact_id=41668. • CRC Guidance • Purpose: Enable the encoding of CRCs • Maturity: Initial proposal available, including a CRC schema (extension to AIXM 5.1). Some aspects still being investigated (e.g. which attributes are subject to CRC wrapping, all or selected ones?) • See: Keep an eye on www.aixm.aero , available on request. AIS-AIMSG-#4

5. Aeronautical Information Exchange ModelSesar developments • Purpose: • Within a SESAR context to deliver validated data models for the Aeronautical Information domain by representing all possible Aeronautical Information constructs, including information for military purposes, which may be exchanged between ATM stakeholders. • Facilitate the development of systems that need to ingest, use, and/or deliver Aeronautical Information. • Output: • AIXM 5 served as Initial load to the ATM Information Reference Model; • Looking into Terrain data models; • Looking at additional requirements for aerodrome mapping data modelling as identified by EUROCAE WG44/RTCA217 deliverables; • Additional validation of selected AIXM 5.1 constructs (e.g. procedures model). • Modeling of Post-Flight Information Report (=> AIS Manual §8.8) • No significant changes to AIXM5.1 identified so far AIS-AIMSG-#4

16. Aeronautical Information SystemsEAD Implementation Mar 2011 New obstacle model based on AIXM 5.1 (on test) Nov 2011 Download Minimum Static Data in AIXM 5.1 Minimum data set(the static data entities required for NOTAM validation and PIB generation required for NOTAM validation and PIB generation) will be available for download in AIXM 5.1 2012 - 2014 Full AIXM 5.1 operations (incremental) First two series of Digital NOTAM events (airspace closure and route closures) will be supported by EAD in Release 7 (mid 2012). This will also come with the possibility to upload an initial set of static data entities in AIXM 5.1 format. Rest of the AIXM 5.1 implementation will be done progressively in EAD, until 2014 incl Digital NOTAM Increment 1. AIS-AIMSG-#4

17. Aeronautical Information Systems -Sesar developments • Digital NOTAM - Application • Main input -> Digital NOTAM Event Specification • User requirements for Digital NOTAM encoding applications • Output (Mid 2012) – validated prototypes for RWY/Airport Closure &Temporary obstacles • Integrated Digital Briefing • Collection of user requirements from pre-SESAR projects • ICAO SARPS • Eurocontrol Integrated Briefing • EAD Specifications • Digital NOTAM Business Case • FAA studies • Etc. • Pre-Flight briefings today • cumbersome to build • too much information • sometimes irrelevant • presented in a format difficult to read by the pilot • Expectations • Graphical capabilities and better filtering based on Digital NOTAM messages will address these shortcomings • AIM Workflow – Relooking at the AIRAC Cycle ?
