| PANS-AIM | Description (PANS-AIM) | AIXM 5 | Remarks |
|---|---|---|---|
| Designator | The full textual designator of the landing and take-off direction. Examples: 27, 35L, 01R. | //aixm:RunwayDirection//aixm:designator | |
| True bearing | The true bearing of the runway. | //aixm:RunwayDirection//aixm:trueBearing | //aixm:RunwayDirection//aixm:trueBearingAccuracy | |
| Threshold - Position | Geographical location for runway threshold | //aixm:RunwayCentrelinePoint//aixm:location/aixm:ElevatedPoint | //aixm:RunwayCentrelinePoint//aixm:location/aixm:ElevatedPoint/aixm:horizontalAccuracy | For more information see Geometry (Overview). |
| Threshold - Elevation | Elevation of the runway threshold | //aixm:RunwayCentrelinePoint//aixm:location/aixm:ElevatedPoint/aixm:elevation | //aixm:RunwayCentrelinePoint//aixm:location/aixm:ElevatedPoint/aixm:verticalAccurracy | The "verticalAccurracy" encoded refers to both the "elevation" and the "geoidUndulation". |
| Threshold - Geoid undulation | WGS-84 Geoid undulation at runway threshold position | //aixm:RunwayCentrelinePoint//aixm:location/aixm:ElevatedPoint/aixm:geoidUndulation | //aixm:RunwayCentrelinePoint//aixm:location/aixm:ElevatedPoint/aixm:verticalAccurracy | The "verticalAccurracy" encoded refers to both the "elevation" and the "geoidUndulation". |
| Threshold - Type | The indication if the threshold is displaced/ not displaced. A displaced threshold is not located at the extremity of a runway. | //aixm:RunwayCentrelinePoint//aixm:role | When encoded "role" = "THR" the threshold is not displaced. When encoded "role" = "DISTHR" the threshold is displaced. |
| Threshold - Displacement | Distance of displaced threshold Note: If displaced threshold | //aixm:RunwayCentrelinePoint//*[aixm:role="DISTHR"]/aixm:associatedDeclaredDistance/aixm:RunwayDeclaredDistance[aixm:type="DTHR"]/aixm:declaredValue/aixm:RunwayDeclaredDistanceValue/aixm:distance | //aixm:RunwayCentrelinePoint//*[aixm:role="DISTHR"]/aixm:associatedDeclaredDistance/aixm:RunwayDeclaredDistance[aixm:type="DTHR"]/aixm:declaredValue/aixm:RunwayDeclaredDistanceValue/aixm:distanceAccuracy | Proposed AIXM Verification Rule It should be ensured that a RunwayDeclaredDistance with type="DTHR" can only be encoded in case the related RunwayCentrelinePoint/role ="DISTHR". |
| Declared distances - TORA | Take-off run available - The length of runway declared available and suitable for the ground run of an aeroplane taking off. | //aixm:RunwayCentrelinePoint//aixm:associatedDeclaredDistance/aixm:RunwayDeclaredDistance[aixm:type="TORA"]/aixm:declaredValue/aixm:RunwayDeclaredDistanceValue/aixm:distance | //aixm:RunwayCentrelinePoint//aixm:associatedDeclaredDistance/aixm:RunwayDeclaredDistance[aixm:type="TORA"]/aixm:declaredValue/aixm:RunwayDeclaredDistanceValue/aixm:distanceAccuracy | TBD: Is there a specific RunwayCentrelinePoint/role required, e.g. START_RUN? If yes a corresponding verification rule may be defined. |
| Declared distances - TODA | Take-off distance available - The length of the take-off run available plus the length of the clearway, if provided. | //aixm:RunwayCentrelinePoint//aixm:associatedDeclaredDistance/aixm:RunwayDeclaredDistance[aixm:type="TODA"]/aixm:declaredValue/aixm:RunwayDeclaredDistanceValue/aixm:distance | //aixm:RunwayCentrelinePoint//aixm:associatedDeclaredDistance/aixm:RunwayDeclaredDistance[aixm:type="TODA"]/aixm:declaredValue/aixm:RunwayDeclaredDistanceValue/aixm:distanceAccuracy | TBD: Is there a specific RunwayCentrelinePoint/role required, e.g. START? If yes a corresponding verification rule may be defined. |
| Declared distances - ASDA | Accelerate-stop distance available - The length of the take-off run available plus the length of the stopway, if provided. | //aixm:RunwayCentrelinePoint//aixm:associatedDeclaredDistance/aixm:RunwayDeclaredDistance[aixm:type="ASDA"]/aixm:declaredValue/aixm:RunwayDeclaredDistanceValue/aixm:distance | //aixm:RunwayCentrelinePoint//aixm:associatedDeclaredDistance/aixm:RunwayDeclaredDistance[aixm:type="ASDA"]/aixm:declaredValue/aixm:RunwayDeclaredDistanceValue/aixm:distanceAccuracy | TBD: Is there a specific RunwayCentrelinePoint/role required, e.g. START_RUN? If yes a corresponding verification rule may be defined. |
| Declared distances - LDA | Landing distance available - The length of runway which is declared available and suitable for the ground run of an aeroplane landing. | //aixm:RunwayCentrelinePoint//aixm:associatedDeclaredDistance/aixm:RunwayDeclaredDistance[aixm:type="LDA"]/aixm:declaredValue/aixm:RunwayDeclaredDistanceValue/aixm:distance | //aixm:RunwayCentrelinePoint//aixm:associatedDeclaredDistance/aixm:RunwayDeclaredDistance[aixm:type="LDA"]/aixm:declaredValue/aixm:RunwayDeclaredDistanceValue/aixm:distanceAccuracy | TBD: Is there a specific RunwayCentrelinePoint/role required, e.g. THR or DISTHR? If yes a corresponding verification rule may be defined. |
| rejected TODA | PANS-AIM discrepancy PANS-AIM chapter 5.3.3.1.1 list a property named "rejected TODA" which is not listed in PANS-AIM Appendix 1 (Aeronautical Data Catalogue). This should rather be considered a data item relevant for the FATO subject. | ||
| Declared distances - Remarks | Remarks including runway entry or start point where alternative reduced declared distances have been declared | //aixm:RunwayCentrelinePoint//aixm:associatedDeclaredDistance/aixm:RunwayDeclaredDistance/aixm:annotation |
