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

Name	Data Type	Definition
role	CodeProcedureFixRoleType	Identifies the function or position the point plays in the approach procedure.
leadRadial	ValBearingType	The lead radial provides information for aircraft with single receiving equipment to change the receiver to the localizer or other facility providing the course guidance and to ensure the aircraft is within the clearance coverage area of LOC facilities before changing frequency or accepting on-course indication.
leadDME	ValDistanceType	The lead DME , like the lead Radial, provides information for aircraft with single receiving equipment to change the receiver to the localizer or other facility providing the course guidance and to ensure the aircraft is within the clearance coverage area of LOC facilities before changing frequency or accepting on-course indication.
indicatorFACF	CodeYesNoType	Indicates the point is also a Final Approach Course Fix (FACF).
reportingATC	CodeATCReportingType	An indicator of the type of position report (e.g., compulsory or on request ) required by an ATC Unit.	Inherited from SegmentPoint
flyOver	CodeYesNoType	Indicates if the aircraft is required to fly directly over the fix. If code is Yes, then it is a 'fly-over' waypoint. If the code is No, then the associated fix is a 'fly-by' waypoint. [ICAO] Waypoints are identified as either flyover or fly-by. Fly-by waypoint. A waypoint which requires turn anticipation to allow tangential interception of the next segment of a route or procedure Flyover waypoint. A waypoint at which a turn is initiated in order to join the next segment of a route or procedure.	Inherited from SegmentPoint
waypoint	CodeYesNoType	A point used for Area Navigation (RNAV) procedures/routes.	Inherited from SegmentPoint
radarGuidance	CodeYesNoType	Radar guidance is possible for reaching an associated point.	Inherited from SegmentPoint
