The properties of the Runway Direction subject listed in PANS-AIM are mapped to the following main AIXM 5 features:
PANS-AIM | Description (PANS-AIM) | AIXM 5 | Remarks |
---|---|---|---|
Designator | The full textual designator of TLOF | //aixm:TouchDownLiftOff/aixm:designator | |
Centre point - Position | Geographical location of TLOF threshold point | //aixm:TouchDownLiftOff/aixm:aimingPoint/aixm:ElevatedPoint | //aixm:TouchDownLiftOff/aixm:aimingPoint/aixm:ElevatedPoint/aixm:horizontalAccuracy | |
Centre point - Elevation | Elevation of the TLOF threshold | //aixm:TouchDownLiftOff/aixm:aimingPoint/aixm:ElevatedPoint/aixm:elevation | //aixm:TouchDownLiftOff/aixm:aimingPoint/aixm:ElevatedPoint/aixm:verticalAccuracy | The "verticalAccurracy" encoded refers to both the "elevation" and the "geoidUndulation". |
Centre point - Geoid undulation | WGS-84 Geoid undulation TLOF centre point position | //aixm:TouchDownLiftOff/aixm:aimingPoint/aixm:ElevatedPoint/aixm:geoidUndulation | //aixm:TouchDownLiftOff/aixm:aimingPoint/aixm:ElevatedPoint/aixm:verticalAccuracy | The "verticalAccurracy" encoded refers to both the "elevation" and the "geoidUndulation". |
Length | The longitudinal extent of TLOF | //aixm:TouchDownLiftOff/aixm:length | AIXM issue AIXM 5 does not provide a "lengthAccuracy" attribute for the "TLOF" feature. PANS-AIM defines an accuracy for the TLOF length. |
Width | The transversal extent of TLOF | //aixm:TouchDownLiftOff/aixm:width | AIXM issue AIXM 5 does not provide a "widthAccuracy" attribute for the "TLOF" feature. PANS-AIM defines an accuracy for the TLOF width. |
Surface type | The surface type of TLOF | //aixm:TouchDownLiftOff/aixm:surfaceProperties/aixm:composition |
