| Threshold point - Position | The beginning of that portion of the FATO usable for landing. | //aixm:RunwayCentrelinePoint//*[aixm:role="THR"]/aixm:location/aixm:ElevatedPoint | //aixm:RunwayCentrelinePoint//*[aixm:role="THR"]/aixm:location/aixm:ElevatedPoint/aixm:horizontalAccuracy In AIXM 5 the Runway and associated classes are used to encode both Runway and FATO. The Runway/type attribute is used to define if the record is an instance of a Runway or a FATO. | |
| Threshold point - Elevation | Elevation of the FATO threshold | //aixm:RunwayCentrelinePoint//*[aixm:role="THR"]/aixm:location/aixm:ElevatedPoint/aixm:elevation | //aixm:RunwayCentrelinePoint//*[aixm:role="THR"]/aixm:location/aixm:ElevatedPoint/aixm:verticalAccuracy | The "verticalAccurracy" encoded refers to both the "elevation" and the "geoidUndulation". |
| Threshold point - Geoid undulation | WGS-84 Geoid undulation at FATO threshold position | //aixm:RunwayCentrelinePoint//*[aixm:role="THR"]/aixm:location/aixm:ElevatedPoint/aixm:geoidUndulation | //aixm:RunwayCentrelinePoint//*[aixm:role="THR"]/aixm:location/aixm:ElevatedPoint/aixm:verticalAccuracy | The "verticalAccurracy" encoded refers to both the "elevation" and the "geoidUndulation". |
| Designation | The full textual designator of the landing and take-off area. | //aixm:Runway//*[aixm:type="FATO"]/aixm:designator | In AIXM 5 the Runway and associated classes are used to encode both Runway and FATO. The Runway/type attribute is used to define if the record is an instance of a Runway or a FATO. |
| Length | The longitudinal extent of FATO | //aixm:Runway//*[aixm:type="FATO"]/aixm:nominalLength | //aixm:Runway//*[aixm:type="FATO"]/aixm:lengthAccuracy | |
| Width | The transversal extent of FATO | //aixm:Runway//*[aixm:type="FATO"]/aixm:nominalWidth | AIXM 5 provides a "widthAccuracy" attribute for the "Runway feature. But accuracy is not specified for the width of a FATO in PANS-AIM. Noteable that for the TLOF width PANS-AIM defines an Accuracy. |
