PointReference
urn:aero:airm:1.0.0:LogicalModel:Subjects:Common:Geometry:PointReference
The location of a significant point defined using a combination of angles and distances based on the navaid system, radar system or special navigation system.
| Properties | Definition | Type |
|---|---|---|
| fixToleranceArea | The area determined by the system use accuracy of the navigation aid(s) on which the fix is based, and the distance from the facility. | TwoDimensionalSurfaceType |
| facilityAngle | missing data | AngleIndication |
| facilityDistance | Distance from the facility to the significant point. | DistanceIndication |
| significantPoint | A significant point defined by a latitude and longitude and/or a combination of angle and/or distance indications. | SignificantPoint |
| role | The role of the defined point reference. | CodeReferenceRoleType |
| postFixTolerance | The error distance from the fix to the latest point where the fix may be received along the flight course. | ValDistanceType |
| priorFixTolerance | The error distance from the fix to the earliest point where the fix may be received along the flight course. | ValDistanceType |
