The coding part of this scenario was documented on Google Drive in draft AIXM 5.1(.1) Digital NOTAM Specification - Part 2 : Coding Rules - This scenario has been transferred to this Conf page and will be updated accordingly. |
...
The temporary outage of structure lighting associated with an obstacle/obstruction.
Notes:
- this scenario covers the outage of lighting associated with existing obstacles that are lighted;
- this scenario covers both airport and en-route obstacles;
- this scenario does not cover other status changes to existing obstacles/obstructions.
...
The following diagram identifies the information items that are usually provided by a data originator for the temporary outage of obstacle lighting.
| Code Block | ||||
|---|---|---|---|---|

input = "obstacle type" [description] [group] [mobile] \n [("location remarks")] "obstacle identification" \n position elevation [height] \n "lighting status" "start time" "end time" [schedule] \n {note} {"affected aerodrome"} {"affected FIR"}. |
The table below provides more details about each information item contained in the diagram. It also provides 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 | value | AIXM mappingobstacle identification | |||||||
An alphanumerical designator by which the obstacle is identified in the national obstacle database | VerticalStructure/VerticalStructurePart.designator | obstacle type | A type of vertical structure. This data item is used (together with other information) in order to search for the VerticalStructure that is concerned. | VerticalStructure.type and VerticalStructure/VerticalStructurePart.type with this list of values CodeVerticalStructureType. | |||||
| description | A textual description of the obstacle, such as the number of similar items for a group, etc. | VerticalStructure.annotation with propertyName="type" and purpose="DESCRIPTION" | |||||||
group | An indication whether Digital NOTAM refers to a group of obstacles with similar height located in close proximity to one another. | VerticalStructure.group with this list of values CodeYesNoType | |||||||
mobile | An indication whether the obstacle has no fixed position. | VerticalStructure/VerticalStructurePart.mobile with this list of values CodeYesNoType | |||||||
| location remarks | A named geographical location where or close to which the obstacle is located (especially for Area 1 obstacles). | VerticalStructure.name or VerticalStructure/VerticalStructurePart.annotation with propertyName='horizontalProjection_location' and purpose="REMARK"
| |||||||
| obstacle identification | An alphanumerical designator by which the obstacle is identified in the national obstacle database. | VerticalStructure/VerticalStructurePart.designator | |||||||
position | The latitude, longitude and possibly the horizontal reference datum associated with the obstacle position. This data item is used (together with other information) in order to search for the VerticalStructure that is concerned. | VerticalStructure/VerticalStructurePart/ElevatedPoint or ElevatedSurface or ElevatedCurve | |||||||
elevation | The elevation (distance from Mean See Level) at the top of the obstacle. | VerticalStructure/VerticalStructurePart/ElevatedPoint or ElevatedSurface or ElevatedCurve ElevatedCurve.elevation including its unit of measure | |||||||
height | The distance between the uppermost and the lowermost parts of the obstacle. | VerticalStructure/VerticalStructurePart.verticalExtent | |||||||
lighting status | The status of the obstacle warning lights. | VerticalStructure/..VerticalStructureLightingStatus.status with the following list of values CodeStatusOperationsType | |||||||
schedule | A schedule might be provided, in case the obstacle is only active according to a regular timetable, within the period between the start of life and the end of life. | VerticalStructure/VerticalStructurePart/Timesheet/... according to the rules for {{Schedules}} | |||||||
start time | The effective date & time when the obstacle starts to exist. This might be further detailed in a "schedule". | VerticalStructure/VerticalStructureTimeSlice.featureLifetime/beginPosition, VerticalStructure/VerticalStructureTimeSlice/validTime/beginPosition, Event/EventTimeSlice.validTime/beginPosition and Event/EventTimeSlice.featureLifetime/beginPosition | |||||||
end time | The end date & time when the obstacle ceases to exist. | VerticalStructure/VerticalStructureTimeSlice.featureLifetime/endPosition, VerticalStructure/VerticalStructureTimeSlice/validTime/endPosition, Event/EventTimeSlice.validTime/endPosition and Event/EventTimeSlice.featureLifetime/endPosition also applying the rules for {{Events with estimated end time}} | |||||||
note | A free text note that provides further details about the obstacle lighting status. | VerticalStructure.annotation with purpose='”REMARK' | |||||||
| affected aerodrome | A reference (name, designator) to one or more airports/heliports that for which the establishment of the area has an operational relevance and needs to be notified to the users thereof. | Event.concernedAirportHeliport | |||||||
| affected FIR | A reference (type, designator) to one or more airspace of type FIR, for which the establishment of the area has an operational relevance and needs to be notified. Note: this needs to be specified only if the geometry of the area is not physically intersecting the geometry of the FIR(s) concerned. | Event.concernedAirspace |
