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
| Indicating the type of position report required by an ATC Unit. Eg.: compulsory or on request. |
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.
