i) FATO

This page contains the mapping for the following data items as defined in PANS-AIM, chapter 5.3.3.1.1

i) FATO (designation, length, width, threshold point);

These properties, which are considered as minimum AIP data set for FATO are mapped to the following main AIXM 5 features:

Note:

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’.

PANS-AIM	Description (PANS-AIM)	AIXM 5	Remarks
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
Threshold point - Elevation	Elevation of the FATO threshold	RunwayCentrelinePoint.location.ElevatedPoint.elevation, RunwayCentrelinePoint.location.ElevatedPoint.verticalAccuracy	The verticalAccurracy encoded refers to both the elevation and the geoidUndulation.
Threshold point - Geoid undulation	WGS-84 Geoid undulation at FATO threshold position	RunwayCentrelinePoint.location.ElevatedPoint.geoidUndulation, RunwayCentrelinePoint..location.ElevatedPoint.verticalAccuracy	The verticalAccurracy encoded refers to both the elevation and the geoidUndulation.
Designation	The full textual designator of the landing and take-off area.	Runway.designator
Length	The longitudinal extent of FATO	Runway.nominalLength Runway.lengthAccuracy
Width	The transversal extent of FATO	Runway.nominalWidth	AIXM 5 provides a Runway.widthAccuracy attribute. But accuracy is not specified for the width of a FATO in PANS-AIM. PANS-AIM issue For "TLOF width" and "Runway width" PANS-AIM defines an accuracy.
