Data item

Description

AIXM mapping

type

The type of area, although this is rarely provided. Typical examples are CTR, AWY or "no type".

Airspace.type with the list of values CodeAirspaceType

class

The airspace classification of the area

Airspace/AirspaceLayerClass.classification with the list of values CodeAirspaceClassificationType.

designator

A designator allocated to the area. However, it is unlikely that such designators are provided by the data originator. It is more likely that the designator will be allocated by the publication office.

Airspace.designator

name

The name of a geographical feature or location, which is also used for identifying the area

Airspace.name

location note

A free text note that indicates the location of the area in relation with relevant geographical or aeronautical features, such as "AT FARNBOROUGH AIRFIELD", etc.

Airspace.annotation with propertyName="geometryComponent" and purpose="REMARK"

horizontal limit

The horizontal shape of the area or of one of its composing volumes (if the area is an aggregation of different volumes with different vertical limits).

Airspace/AirspaceVolume.horizontalProjection following the rules for encoding for encoding {{Geometrical and geographical data}}. The AirspaceGeometryComponent shall have operation="BASE" and operationSequence="1". Only geometries of type Polygon, Circle or Corridor are allowed in this scenario."

excluded airspace

A reference (type, designator, name) to one or more airspace that are excluded (subtracted) from the volume described by the aggregation of the horizontal limits specified for the area; for example: "EXCLUDING THE HEATHROW CTR".

Airspace/AirspaceVolume.contributorAirspace

lower limit

The lower limit (value, unit of measurement and vertical reference) of the area.

Airspace/AirspaceVolume.lowerLimit and lowerLimitReference

upper limit

The upper limit (value, unit of measurement and vertical reference) of the area.

Airspace/AirspaceVolume.upperLimit and upperLimitReference

concerned airspace

The indication of AirportHeliport featureAirspace feature(s) in the vicinity of which the area is located and/or the FIR impacted. 

In order to facilitate the work of the operator, the Digital NOTAM data provider interface should include the following functionality:

  • automatically identify the FIR in which the area is located,
  • automatically identify CTR and TMA that are intersected by the area,

In all situations, the operator shall be allowed to take the final decision by selecting the airports/FIR which are affected by the area. This might include additional ones, which have not been identified automatically by the spatial checks but have an operationally significant relation with the area.

Event.concernedAirspace href
concerned airport/heliport

The indication of AirportHeliport feature(s) in the vicinity of which the area is located. 

In order to facilitate the work of the operator, the Digital NOTAM data provider interface should include the following functionality:

  • if the area does not intersect any TMA or CTR but it's lowerLimit is equal or less than 1000 FT from SFC, then automatically identify the AirportHeliport that have their ARP located within 5 NM (configurable parameter) and locationIndicatorICAO="YES"; 

In all situations, the operator shall be allowed to take the final decision by selecting the airports/FIR which are affected by the area. This might include additional ones, which have not been identified automatically by the spatial checks but have an operationally significant relation with the area.

Event.concernedAirportHeliport href

start time

The effective date & time when the area becomes established and active. This might be further detailed in a "schedule".

Airspace/AirspaceTimeSlice.featureLifetime/beginPosition, Airspace/AirspaceTimeSlice/validTime/timePosition, Event/EventTimeSlice.validTime/timePosition and Event/EventTimeSlice.featureLifetime/beginPosition

end time

The end date & time when the area ceases to exist. It might be an estimated value, if the exact end of activation is unknown. It may also be indeterminate for a permanent area.

Airspace/AirspaceTimeSlice.featureLifetime/endPosition Event/EventTimeSlice.featureLifetime/endPosition also applying the rules for {{Events with estimated end time}}

schedule

A schedule might be provided in case the area is only active according to a regular timetable, within the overall period when it exists.

Airspace/AirspaceActivation/Timesheet/... according to the rules for {{Schedules}}

controlling unit note

A free text note that provides information about the unit or service that provides ATS services in the area.

Airspace/AirspaceActivation.annotation with propertyName="status" and purpose="REMARK", according to the rules for encoding annotations

note

A free text note that provides further instructions concerning the area, such as the reason that led to the area establishment, etc.

Airspace/AirspaceActivation.annotation with purpose=””REMARK”, according to the rules for encoding annotations
