Data item

value

AIXM mapping

obstacle type

A type of vertical structure. The item is used alone or in combination with other attributes in order to identify the obstacle concerned.

VerticalStructure.type and VerticalStructure/VerticalStructurePart.type

descriptionA textual description of the obstacle, such as the number of similar items for a group, etc. The item is used alone or in combination with other attributes in order to identify the obstacle concerned.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, coded as a single VerticalStructure

VerticalStructure.group 

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 has probably been 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

Only the value 'UNSERVICEABLE' is supported in this scenario.

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/VerticalStructureLightingStatus/Timesheet/... according to the rules for {{Schedules}}

start time

The effective date & time when the temporary change of an obstacle's light status starts. 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 effective date & time when the temporary change of an obstacle's light status ends.

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/VerticalStructureLightingStatus.annotation with purpose='”REMARK'

affected aerodrome

A reference (name, designator) to one or more airports/heliports that for which the establishment of the obstacle light outage has an operational relevance and needs to be notified to the users thereof.

Note: Attention: the data provider interface shall warn the operator to check if the information received from the originator is consistent with the airport(s) for which the obstacle is situated in the area of interest for obstacles, as automatically calculated by the application using the obstacle positional data (lat/long).

Event.concernedAirportHeliport
affected FIR

A reference (type, designator) to one or more airspace of type FIR, for which the obstacle light outage has an operational relevance and needs to be notified.

Notethe FIR within which the obstacle is physically situated does not need to be provided by the data originator. It will be automatically identified by the application that enables the coding of the Event. If an additional FIR is specified by the originator, the application should check the plausibility of this data based on the FIR boundary.
