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

Gap analysis AIXM/NOTAM content

• Based on NOTAM Selection Criteria (NSC)
• 23 letters codes (subject) AIXM entities
• 45 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

8
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)
