|---|---|---|---|---|---|---|---|---|---|---|
| Designator | The full textual designator of the landing and take-off direction. Examples: 27, 35L, 01R. | //aixm:RunwayDirection//aixm:designator 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. | //aixm:RunwayDirection//aixm:RunwayDirection.designator.trueBearing |and //aixm:RunwayDirection//aixm:trueBearingAccuracyRunwayDirection.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 | //aixm:RunwayCentrelinePoint//aixm:location/aixm:ElevatedPoint | //aixm:RunwayCentrelinePoint//aixm:location/aixm:ElevatedPoint/aixm:horizontalAccuracy | For more information see Geometry (Overview) 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 | //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" 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 | //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" 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 requires the Geoid undulation of the threshold for precision approach runways and for non-precision approaches runways of aerodromes used by international civil aviation.
| |||||
| 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:roleRunwayCentrelinePoint.role | role: The role of an operationally significant position on the centre line of a runway direction. | When encoded "role" = "THR" role equal to 'THR' the threshold is not displaced. When encoded "role" = "DISTHR" role equal to 'DISTHR' the threshold is displaced. | ||||||
