Data item | value | AIXM mapping |
obstacle 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. |
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 |
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.elevation including its unit of measure |
height | The distance between the uppermost and the lowermost parts of the obstacle. | VerticalStructure/VerticalStructurePart.verticalExtent |
lights 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 |
