i) FATO

The properties of the FATO subject listed in PANS-AIM are mapped to the following main AIXM 5 features:


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
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.
