6. 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

12. AIXM 5.1 Geometry Based on a geometry subset of GML Curves: Surfaces:
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

16. 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
NO_SEQ = 1
1% Plausibility Rule extended:
Calculated distance [VERTEX – CENTRE] versus VAL_RADIUS_ARC
Current: ABS(D1-D1)/D1<=1%
NEW: ABS(D1-R)/D1<=1% D1 R D2
AIXM 4.5 to 5.1 Mapping
NO_SEQ = 2

19. 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The Object is withdrawn, but the feature still exists
