This is a specialization of the SegmentLeg class and it inherits all attributes and associations of that class.

Name	Data Type	Definition
endConditionDesignator	CodeSegmentTerminationType	An indication of the event that allows identifying the end of the leg and the start of the next leg on the procedure. For example, reaching an altitude or outbound timing.	Inherited from SegmentLeg
legPath	CodeTrajectoryType	A code defining a specific type of flight path such as arc, base turn outbound, base turn inbound, track, proc turn, hold in lieu.	Inherited from SegmentLeg
legTypeARINC	CodeSegmentPathType	A comprehensive description of the 'path and terminator' concept is given in ARINC Specification 424, Attachment 5, Path and Terminator.	Inherited from SegmentLeg
course	ValBearingType	The value of the course angle in degrees.	Inherited from SegmentLeg
courseType	CodeCourseType	A code indicating the type of course to be observed. E.g. true track, magnetic track, heading, VOR radial, true bearing, magnetic bearing.	Inherited from SegmentLeg
courseDirection	CodeDirectionReferenceType	Indicates flight direction to/from the navaid providing the course guidance.	Inherited from SegmentLeg
turnDirection	CodeDirectionTurnType	A code indicating the direction of the turn.	Inherited from SegmentLeg
speedLimit	ValSpeedType	The value of the speed limit on the procedure leg. Rules: As a plausibility rule, value should be equivalent to between 0 and 400, when expressed in Km/h.	Inherited from SegmentLeg
speedReference	CodeSpeedReferenceType	A code indicating the reference system for a speed value.	Inherited from SegmentLeg
speedInterpretation	CodeAltitudeUseType	A code indicating how the speed attributes of a procedure leg should be interpreted.	Inherited from SegmentLeg
bankAngle	ValAngleType	The recommended bank angle of the aircraft on the turn. Rules: As a plausibility rule, value should be between 5 and 35 degrees.	Inherited from SegmentLeg
length	ValDistanceType	Length of the segment	Inherited from SegmentLeg
duration	ValDurationType	Segment duration	Inherited from SegmentLeg
procedureTurnRequired	CodeYesNoType	Indicates if a procedure turn is required at the end of the segmentleg. Default is No.	Inherited from SegmentLeg
upperLimitAltitude	ValDistanceVerticalType	The value of the upper altitude used with codeDescrDistVer: At or below the higher altitude. Between the lower and the upper altitude.	Inherited from SegmentLeg
upperLimitReference	CodeVerticalReferenceType	A code indicating the reference for a vertical distance. Two series of values exist: 1) real distance: from GND, from the MSL, from the WGS-84 ellipsoid 2) pressure distance: QFE, QNH, STD.	Inherited from SegmentLeg
lowerLimitAltitude	ValDistanceVerticalType	The lower limit altitude. used with codeDescrDistVer: At or above the lower altitude. At the lower altitude Between the lower and the upper altitude. Lower altitude is recommended. Expect lower altitude by ATC.	Inherited from SegmentLeg
lowerLimitReference	CodeVerticalReferenceType	A code indicating the reference for a vertical distance. Two series of values exist: 1) real distance: from GND, from the MSL, from the WGS-84 ellipsoid 2) pressure distance: QFE, QNH, STD.	Inherited from SegmentLeg
altitudeInterpretation	CodeAltitudeUseType	A code indicating how the altitude attributes of a procedure leg should be interpreted.	Inherited from SegmentLeg
altitudeOverrideATC	ValDistanceVerticalType	Alternate altitude when directed by Air Traffic Control	Inherited from SegmentLeg
altitudeOverrideReference	CodeVerticalReferenceType	A code indicating the reference for a vertical distance. Two series of values exist: 1) real distance: from GND, from the MSL, from the WGS-84 ellipsoid 2) pressure distance: QFE, QNH, STD.	Inherited from SegmentLeg
verticalAngle	ValAngleType	The value of the vertical climb angle of the aircraft on the procedure leg. A negative value means descent. Rules: As a plausibility rule, value should be between -10 and +50 degrees.	Inherited from SegmentLeg
