Presentation Transcript

  1. Introduction • “Never let an aircraft take you somewhere your brain didn't get to five minutes earlier” Air Transportation Information Airspace structures and routes Ground Infrastructure Rules and procedures Terrain and obstacles Passenger MET Surveillance Flight The structure of the information is captured in models

  2. AIXM – why necessary • EAD Feasibility Study (by “CAPdebis”) - 1993 • “The exchange of static data in an electronic format is rare for ground based systems. Other than ARINC 424 format, which was developed according to the demands of FMS, a state of the art, commonly used standard format for the exchange of static data information […] is not available.” • Need for aeronautical information logical model + data exchange format • For the implementation of the European AIS Database (EAD) • Basis for eAIP • Contribution to ICAO (AIS/MAP Divisional Meeting of 1998) • For industry implementations • etc.

  3. AIXM Scope Air Transportation Information AIXM Airspace structures and routes Ground Infrastructure Rules and procedures Terrain and obstacles Passenger MET Surveillance Flight

  4. AIXM in EAD Provided by industry Chart Production Static data Update (e)AIP Production AIXM Logical Model Digital Data Input (AIXM XML) Support NOTAM production AIXM XML output

  5. ICAO AIS to AIM Roadmap 3 phases 21 inter-related steps Time

  6. Aeronautical Data Quality (ADQ) • ADQ 1 • COMMISSION REGULATION (EU) No 73/2010 • “laying down requirements on the quality of aeronautical data and aeronautical information for the single European sky” • Basically; Turning Annex 15 into European Law • Compliance dates: 2013-2017 • Means of Compliance • Electronic AIP (eAIP) Published • Aeronautical Information Exchange (AIX) Final Draft • AIXM 5.1 is proposed as compliant model • Data Quality Requirements (DQR) Under development • Data Assurance Levels (DAL) Under development • Data Origination (DO) Under development

  7. AIXM version 5 Joint development EUROCONTROL – FAA (with the support of the international AIS community)

  8. AIXM 5 Design Objectives New capabilities Expand/Refresh Domain Model Modularity Technical Design Decisions Extensibility Aerodrome Mapping ISO19100series FlexibleExchange Terminal Procedures UML FlexibleMessages Obstacles GML 3.2 Static and Dynamic Metadata Integrity External Constraints

  9. XSD Temporality Concept AIXM version 5.1 UML www.aixm.aero

  10. AIXM 5.1 – Digital NOTAM capability TWY closure • Currently, published as NOTAM A0874/03 NOTAMN Q) EBBU/QMXLC/IV/M/A/000/999/5054N00429E005 A) EBBR B) 0308250500 C) 0310271600 E) TAXIWAYS OUTER 7 AND E6 CLSD <OK for computers> <not OK for computers> • In future, published as an AIXM 5.1 encoded message • for intelligent machine use • e.g., graphical visualisation • equally suitable for in-flight and ground systems • Text NOTAM messages generated from AIXM 5.1 encoding

  11. www.aixm.aero

  12. AIXM - Wiki www.aixm.aero/wiki

  13. AIXM Temporality document

  14. Implementation Guidance • GML Guidelines for aviation data • Encoding rules / conventions • Profile • OGC Aviation Domain WG • See OGC Portal

  15. Implementation Guidance • Use of xlink:href and UUID

  16. Implementation Guidance • Metadata Profile • Requirements for Aviation Metadata • Guidance on the Aviation Metadata Profile • Business Rules • CRC • Etc.

  17. Global AIM Congress of 2006 • Recommendation 1 • “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”

  18. AIXM 5.1 proposed to ICAO mandate International AIXM Change Control Board AIS-AIM SG AIXM 5.1 and further Updates AIXM 5.0 Pre-AIXM 5 2011 2012 2010 2009 2008 2007 2006

  19. ICAO SARPS AMDT 37 expected to make this a mandatory requirement and provide more details

  20. Draft AMDT 37 to Annex 15 See: http://www2.icao.int/en/ais-aimsg/AISAIM%20Meeting%20MetaData/SN%202%20complete.pdf

  21. Draft AMDT 37 to Annex 15

  22. Why a new AIXM Change Control Board • Transparency • Stakeholder representation • States, Military • ANSP, Service Providers • Airlines, Airports • Manufacturing industry • Decisions by consensus! • Change proposals developed collectively • If no serious disagreement with a change proposal is notified (silent process) -> adopted • A widely acceptable solution needs to be found for any issue!

  23. Roles • CCB Member • Any AIXM stakeholder (organisation) • Raise/comment issues • Develop/review change proposals • CCB Secretariat - Eurocontrol and FAA • JIRA maintenance • Drives the change proposal process • but does not take decisions in isolation! • Implements the model changes • Maintains www.aixm.aero and related Web sites • CCB Advisory Board • Maximum 20 members - Representatives of stakeholder groups • Maintain the “AIXM CCB Charter” • Witness the correctness of the CCB process • Receive regular reports from Secretariat • Not requested to approve individual changes!

  24. Future versions policy • Major Version (v.5, v.6, etc.) • None foreseen for the moment • Intermediate Version (v.5.x, v.6.x, etc.) • AIXM 5.2 not earlier than 2013 • CCB process to start in Q2 2012 • Minor Version (v.5.1.x, v.5.2.x, etc.) • Probably AIXM 5.1.1 in 2012
