Enabling and demonstratingaerodrome digital NOTAMs

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

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

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)

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

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”

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

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
