  1. AMDB/xNOTAM Study“Study on the applicability of the xNOTAM concept for updating Airport Mapping Database (AMDB) applications“Overview

  2. Study Objective Enabling and demonstratingaerodrome digital NOTAMs

  3. Main Goals • Extension of AIXM to support AMDB data • Gap analysis DO-272A/ED-99A – AIXM Conceptual Model • Validation of the xNOTAM concept • Gap analysis NOTAM – AIXM Conceptual Model • Prototype AIXM 5 XML schema • Demonstration of study results in flight simulator

  4. Extension of AIXM with AMDB support • Based on AIXM 4.5 model and AMDB Specifications • AIXM Extensions • Generic geometry support (AIXM5: ISO19100) • AMDB features and attributes mapped to AIXM entities • Added features (markings, lines,…) and attributes to AIXM AMDB AIXM 4.5

  5. Gap analysis AIXM/NOTAM content • Based on NOTAM Selection Criteria (NSC) • 2+3 letters codes (subject): AIXM entities • 4+5 letters codes (condition): AIXM attributes • Works for subjects (MR → Rwy, MX → Twy, MN → Apron...) • Mapping of conditions to attributes difficult • Often not used as intended (“XX”) • Not precise enough • Actual information onlyin item E) Q)EDFF/QMXLC/IV/M/A/000/999/5002N00834E005 NSC Subjects MA MOVEMENT AREA MB BEARING STRENGTH MC CWY MD DECLARED DISTANCES MG TAXIING GUIDANCE SYSTEM MK PARKING AREA MX TWY … NSC Conditions AD Available for daylight operation AG Operating but ground checked only AH Hours of service are….

  6. AIXM/NOTAM Gap Analysis Major Findings • Gaps in entities could be resolved easily • Gaps in attributes could be resolved partially • NSC not sufficient for structuring, need to investigate Item E) • Amount of NOTAMs analysed within this study: ~100 • Leading to ~85% coverage of AIXM for NOTAM data • Conclusion • Must analyse many more NOTAMs (~200) to get to 95% • More than 99% will never be achieved A3322/06 NOTAMN Q)LIXX/QXXXX/IV/M/E/000/999/4007N01358E330 A)LIMM LIRR LIBB B)0607092045 C)0607092115 E)SPECIAL NOTICE: GERMANY 2006 FIFA WORLD CUP - WINNER : ITALY CAMPIONI DEL MONDO CHAMPIONS OF THE WORLD MEISTER DER WELT CHAMPIONS DU MONDE CAMPEONES DEL MUNDO CAMPE/ES DO MUNDO MESTERE AV VERDENEN KAMPIOENEN VAN DE WERELD

  7. Prototype AIXM 5 Schema • Based on extended model (after the two gap analyses) • First AIXM 5 implementation • Based completely on GML • Generic geometry support • Temporality model based on GML “Timeslices”

  8. digital NOTAM digital NOTAM Decoder Demonstration of Study Results • Display temporary change in processed form to cockpit crew • AIXM digital NOTAM message announces temporary change • Visualize change information on cockpit display “static” database (AMDB)

  9. Demonstration Scenario • Three typical situations announced in NOTAM • “Runway closed for…” (NSC QMRLC) • “Part of taxiway closed” (NSC QMXLC) • “Obstacle erected” (NSC QOBCE) • Taxi display symbology RWY operating mode restriction TWY operating mode restriction Obstacle symbols (with height)

  10. Demonstration – Video
