| 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:SurfaceCharacteristics/aixm:composition |
