Inheritance
This is a specialization of the ApproachLeg class and it inherits all attributes and associations of that class.
List of attributes
| Name | Data Type | Definition | |
|---|---|---|---|
| requiredNavigationPerformance | CodeRNPType | [ICAO] Required navigation performance (RNP). [ICAO] Specifies the minimum navigation performance accuracy required in an airspace. It is the navigation performance accuracy of all the user and navigation system combinations within an airspace. Note: It is a tolerance factor for flying. The factor is taken into consideration when determining protected airspace for aircraft. | |
| 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 |
