Name	Data Type	Definition
designator	TextDesignatorType	The designator of a runway, used to uniquely identify it at an aerodrome/heliport.
type	CodeRunwayType	The type can be either runway for airplanes or Final Approach and Take-off Area (FATO) for helicopters.
nominalLength	ValDistanceType	The declared longitudinal extent of the runway for operational (performance) calculations.
lengthAccuracy	ValDistanceType	Accuracy of the value of the physical length of the runway.
nominalWidth	ValDistanceType	The declared transversal extent of the runway for operational (performance) calculations.
widthAccuracy	ValDistanceType	Accuracy of the value of the physical width of the runway.
widthShoulder	ValDistanceType	The runway shoulder width.
lengthStrip	ValDistanceType	The physical length of the strip. Where a strip is a defined area including the runway and, if applicable, the stopway.
widthStrip	ValDistanceType	The physical width of the strip. Where a strip is a defined area including the runway and, if applicable, the stopway.
lengthOffset	ValDistanceSignedType	A value specifying the longitudinal offset of the strip, when it is not symmetrically extended beyond the two runway ends. Where a strip is a defined area including the runway and, if applicable, the stopway.
widthOffset	ValDistanceSignedType	A value specifying the lateral offset of the strip, when it is not symmetrically extended beyond the two runway edges. Where a strip is a defined area including the runway and, if applicable, the stopway.
abandoned	CodeYesNoType	An indicator that the surface is no longer in operational use, but is still physically present and visible, although usually in a degraded state.
