Types of Mapping
• One (AICM 4.5) Entity -> One (AIXM 5.1) Feature• AUTH_FOR_AIRSPACE -> AuthorityForAirspace
• One (AICM 4.5) Entity -> Several (AIXM 5.1) Features• DME -> DME & Navaid
• Several (AICM 4.5) Entities -> One (AIXM 5.1) Feature• ENR_ROUTE_RTE & RTE_SEG -> Route
• One (AICM 4.5) Entity -> One (AIXM 5.1) Object• AIRCRAFT_CLASS -> AircraftCharacteristics
• One (AICM 4.5) Attribute / Relationship -> One (AIXM 5.1) Property• CODE_TYPE -> type
• One (AICM 4.5) Attribute -> Several (AIXM 5.1) Properties• EN_ROUTE_RTE TXT_DESIG -> Route designatorPrefix,
designatorSecondLetter, designatorNumber

AIXM 5.1 Geometry
• Based on a geometry subset of GML
• Curves: • ArcByCenterPoint, CircleByCenterPoint, ArcString, Arc, Circle,
GeodesicString, Geodesic, LineStringSegment
• Surfaces:• PolygonPatch, Rectangle, Triangle
• Complemented by the OGC Aviation Domain Working Group discussion paper: Use of GML in Aeronautical Data• ArcByCenterPoint – reference system, direction of angle measurement• Rhumb Line (Loxodrome) – GML geodesic segment

SDO Compatibility – New Mandatory Attributes
• SDO (AICM 4.5) Business Rule for CWA & CCA:
• Qualify a new mandatory attribute: VAL_RADIUS_ARC
AIXM 4.5 to 5.1 Mapping 17
SDO Compatibility – New Plausibility Check
• 1% Plausibility Rule extended: • Calculated distance [VERTEX – CENTRE] versus
VAL_RADIUS_ARC

Mapping Impact on AIXM 5.1 Temporality
• Entity to Object Mapping• Two AICM 4.5 entities map into an AIXM 5.1 feature and an
Object• E.g.: ORG_AUTH & ORG_AUTH_ASSOC
• Cancel Future Committed Data• EAD SDO Rule: One slot committed with an earlier date
cancels any future committed data version• Same principles to be applied in AIXM 5.1 implementation
• Withdrawal of an AICM 4.5 Entity mapping into an AIXM 5.1 Object• The Object is withdrawn, but the feature still exists
