This page contains the mapping for the following data items as defined in PANS-AIM, chapter 5.3.3.1.1
h) Runway Direction (designator, true bearing, threshold, TORA, TODA, ASDA, LDA,);
These properties, which are considered as minimum AIP data set for Runway direction are mapped to the following main AIXM 5 features:

| PANS-AIM | Description (PANS-AIM) | AIXM 5 | Definition (AIXM 5.1.1) | Remarks |
|---|---|---|---|---|
| Designator | The full textual designator of the landing and take-off direction. Examples: 27, 35L, 01R. | RunwayDirection.designator | RunwayDirection: One of the two landing and take-off directions of a runway for which attributes like Take-off Run Available (TORA), Take-off Distance Available (TODA), Landing Distance Available (LDA), etc. may be defined. designator: A designator for one of the two possible landing and/or take-off directions of a runway or Final Approach and Take-off Area (FATO). | |
| True bearing | The true bearing of the runway. | RunwayDirection.designator.trueBearing and RunwayDirection.designator.trueBearingAccuracy | trueBearing: The accuracy of the measured angle between the runway direction and True North at a given position. trueBearingAccuracy: The measured angle between the runway direction and Magnetic North at a given position. | |
| Threshold - Position | Geographical location for runway threshold | RunwayCentrelinePoint.location.ElevatedPoint and RunwayCentrelinePoint.location.ElevatedPoint.horizontalAccuracy | RunwayCentrelinePoint: An operationally significant position on the centre line of a runway direction. A typical example is the runway threshold. location: Geographical position of the runway centreline point. horizontalAccuracy: The difference between the recorded horizontal coordinates of a point and its true position referenced to the same geodetic datum expressed as a circular error at 95 percent probability. | |
| Threshold - Elevation | Elevation of the runway threshold | RunwayCentrelinePoint.location.ElevatedPoint.elevation and RunwayCentrelinePoint.location.ElevatedPoint.verticalAccuracy | elevation: The vertical distance of the point measured from Mean Sea Level (MSL). verticalAccuracy: The difference between the recorded elevation of a point and its true elevation referenced to the same vertical datum expressed as a linear error at 95 percent probability. | |
| Threshold - Geoid undulation | WGS-84 Geoid undulation at runway threshold position | RunwayCentrelinePoint.location.ElevatedPoint.geoidUndulation and RunwayCentrelinePoint.location.ElevatedPoint.verticalAccuracy | geoidUndulation: The distance of the geoid above (positive) or below (negative) the mathematical reference ellipsoid at the location of the point. | ICAO Annex Annex 14 Info for accuracy The PANS-AIM Data Catalogue does not define an accuracy for the Geoid undulation but ICAO Annex Annex 14 does. In AIXM 5 the verticalAccuracy refers to both the elevation and the geoidUndulation. Hence, if the verticalAccuracy is coded for elevation but the accuracy for the Geoid undulation is not known, this should be put into a corresponding Note. |
| Threshold - Type | The indication if the threshold is displaced/ not displaced. A displaced threshold is not located at the extremity of a runway. | RunwayCentrelinePoint.role | role: The role of an operationally significant position on the centre line of a runway direction. | When encoded role equal to 'THR' the threshold is not displaced. When encoded role equal to 'DISTHR' the threshold is displaced. |
| Threshold - Displacement | Distance of displaced threshold Note: If displaced threshold | RunwayCentrelinePoint.role equal-to 'DISTHR' .associatedDeclaredDistance.RunwayDeclaredDistance.type equal-to 'DTHR' .declaredValue.RunwayDeclaredDistanceValue.distance and RunwayCentrelinePoint.role equal-to 'DISTHR' .associatedDeclaredDistance.RunwayDeclaredDistance.type equal to 'DTHR' .declaredValue.RunwayDeclaredDistanceValue.distanceAccuracy | associatedDeclaredDistance: The declared distance marked by the RunwayCentrelinePoint. type: The type of a conventional operational distance declared for a runway direction. declaredValue: Schedule of validity for the Declared Distances. distance: The conventional operational distance declared for a runway direction. distanceAccuracy: The accuracy of the value of a conventional operational distance declared for a runway direction. | AIXM 5.1(.1) issue_020_declaredValue Definition of declaredValue shall be reviewed. Workaround AIXM 5.1(.1): NA Status AIXM 5.1: to be reported to AIXM CCB. |
| Declared distances - TORA | Take-off run available - The length of runway declared available and suitable for the ground run of an aeroplane taking off. | RunwayCentrelinePoint.role.associatedDeclaredDistance.RunwayDeclaredDistance.type equal-to 'TORA' .declaredValue.RunwayDeclaredDistanceValue.distance and RunwayCentrelinePoint.role.associatedDeclaredDistance.RunwayDeclaredDistance.type equal-to 'TORA' .declaredValue.RunwayDeclaredDistanceValue.distanceAccuracy | see above | |
| Declared distances - TODA | Take-off distance available - The length of the take-off run available plus the length of the clearway, if provided. | RunwayCentrelinePoint.role.associatedDeclaredDistance.RunwayDeclaredDistance.type equal-to 'TODA' .declaredValue.RunwayDeclaredDistanceValue.distance and RunwayCentrelinePoint.role.associatedDeclaredDistance.RunwayDeclaredDistance.type equal-to 'TODA' .declaredValue.RunwayDeclaredDistanceValue.distanceAccuracy | see above | |
| Declared distances - ASDA | Accelerate-stop distance available - The length of the take-off run available plus the length of the stopway, if provided. | RunwayCentrelinePoint.role.associatedDeclaredDistance.RunwayDeclaredDistance.type equal-to 'ASDA' .declaredValue.RunwayDeclaredDistanceValue.distance and RunwayCentrelinePoint.role.associatedDeclaredDistance.RunwayDeclaredDistance.type equal-to 'ASDA' .declaredValue.RunwayDeclaredDistanceValue.distanceAccuracy | see above | RunwayCentrelinePoint.role shall be 'START_RUN' |
| Declared distances - LDA | Landing distance available - The length of runway which is declared available and suitable for the ground run of an aeroplane landing. | RunwayCentrelinePoint.role.associatedDeclaredDistance.RunwayDeclaredDistance.type equal-to 'LDA' .declaredValue.RunwayDeclaredDistanceValue.distance and RunwayCentrelinePoint.role.associatedDeclaredDistance.RunwayDeclaredDistance.type equal-to 'LDA' .declaredValue.RunwayDeclaredDistanceValue.distanceAccuracy | see above | RunwayCentrelinePoint/role shall be either 'THR' or 'DISTHR'. |
| Declared distances - Remarks | Remarks including runway entry or start point where alternative reduced declared distances have been declared | RunwayCentrelinePoint.associatedDeclaredDistance .RunwayDeclaredDistance.annotation, or RunwayCentrelinePoint.associatedDeclaredDistance .RunwayDeclaredDistance.declaredValue.RunwayDeclaredDistanceValue.annotation | The Note may be provided for the appropriate declared distance property or class. |
