In AIXM 5 the Runway and its 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. Hence, a FATO has to be encoded as Runway with type equal-to ‘FATO’. |

| Threshold point | The beginning of that portion of the FATO usable for landing. | RunwayCentrelinePoint.role equal-to'THR' | |||||||
| Threshold point - Position | Geographical location of FATO threshold point | RunwayCentrelinePoint.location.ElevatedPoint, RunwayCentrelinePoint.location.ElevatedPoint.horizontalAccuracy | |||||||

| 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. | Runway.designator | |||||

| Width | The transversal extent of FATO | //aixm:Runway//*[aixm:type="FATO"]/aixm:Runway.nominalWidth | AIXM 5 provides a Runway.widthAccuracy attribute . But accuracy is not specified for the width of a FATO in PANS-AIM.
