Data item

value

AIXM mapping

obstacle type

A type of vertical structure. 

VerticalStructure.type and VerticalStructure/VerticalStructurePart.type with this list of values CodeVerticalStructureType.

descriptionA 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).

The item is used alone or in combination with other attributes in order to identify the obstacle concerned.

VerticalStructure/VerticalStructurePart.annotation with propertyName='horizontalProjection_location' and purpose="REMARK"

titleAIXM 5.1 workaround

In AIXM 5.1, the _ character is not allowed in the pattern for propertyName, therefore, when using AIXM 5.1, the propertyName should be left empty.

obstacle identificationAn alphanumerical designator by which the obstacle is identified in the national obstacle database.VerticalStructure.name

position

The latitude, longitude and possibly the horizontal reference datum associated with the obstacle position.

The item is used alone or in combination with other attributes in order to identify the obstacle concerned.

VerticalStructure/VerticalStructurePart/ElevatedPoint or ElevatedSurface or ElevatedCurve

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 temporary change of an obstacle's light status 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 effective date & time when the obstacle ceases to existtemporary change of an obstacle's light status ends.

VerticalStructure/VerticalStructureTimeSlice.featureLifetime/endPosition, VerticalStructure/VerticalStructureTimeSlice/validTime/endPositionEvent/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 aerodromeA 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
