The table below provides more details about each information item contained in the diagram. It also provided the mapping of each information item within the AIXM 5.1 structure. The name of the variable (first column) is recommended for use as label of the data field in human-machine interfaces (HMI).
Data item | valueDescription | AIXM mapping |
|---|---|---|
route availability | An explicit indication that the route portion is closed. | RouteSegment/RouteAvailability.status with the list of values CodeRouteAvailabilityType |
route designator | The published designator of the route concerned. This information, in combination with the start/end point is used to identify the route segments concerned. | RouteSegment.routeFormed |
start point | The designator and eventually the type (in the case of a Navaid) of the significant point from where the route availability is affected. This information, in combination with the route designator and the end point is used to identify the route segments concerned. | RouteSegment.start/EnRouteSegmentPoint.pointChoice |
end point | The designator and eventually the type (in the case of a Navaid) of the significant point until where the route availability is affected. This information, in combination with the route designator and the start point is used to identify the route segments concerned. | RouteSegment.end/EnRouteSegmentPoint.pointChoice |
lower limit | The vertical level above which and including that level is affected by the closure. | RouteSegment/RouteAvailability/AirspaceLayer.lowerLimit and lowerLimitReference |
upper limit | The vertical level below which and including that level is affected by the closure. | RouteSegment/RouteAvailability/AirspaceLayer.upperLimit and upperLimitReference |
| direction | An indication of the direction in which the route segment is considered for closure. | RouteSegment/RouteAvailability.direction |
start time | The effective date & time when the closure starts. This might be further detailed in a "schedule". | RouteSegment/RouteSegmentTimeSlice/TimePeriod.beginPosition, Event/EventTimeSlice.validTime/timePosition and Event/EventTimeSlice.featureLifetime/beginPosition |
end time | The effective date & time when the closure ends. | RouteSegment/RouteSegmentTimeSlice/TimePeriod.endPosition and Event/EventTimeSlice.featureLifetime/endPosition also applying the rules for {{Events with estimated end time}} |
schedule | A schedule might be provided in case of the closure only being effective according to a regular timetable, within the period between the start time and the end time. | RouteSegment/RouteAvailability/Timesheet/… according to the rules for {{Schedules}} |
note | A free text note that provides further details concerning the route closure, such as reason, alternate routes, etc. | Route/RouteAvailability.annotation with purpose=”REMARK” |
