Purpose & Scope
This page and its child pages contain the coding guidelines for the minimum and conditional data for the airspace subjects as defined in PANS-AIM, for both ATS Airspace and Special activity airspace.
In the PANS-AIM Aeronautical Data Catalogue, ATS airspace is defined as follows:
Airspaces of defined dimensions, alphabetically designated, within which specific types of flights may operate and for which air traffic services and rules of operation are specified
PANS-AIM lists the following types of ATS airspaces:
PANS-AIM does not define Special activity airspace but is does list a set of airspace types that are considered Special activity airspaces in the Aeronautical Data Catalogue:
- Prohibited Area
- Restricted Area
- Danger Area
- Military Exercise Area
- Military Training Area
- Air Defence Identification Zone (ADIZ)
In the PANS-AIM Aeronautical Data Catalogue also properties for 'Aerial sporting activities airspace' and 'Other regulated airspace' are defined.
In an AIP, these types of airspaces (and other types) are published in the following sections:
- ENR 5.1 Prohibited, restricted and danger areas
ENR 5.2 Military exercise and training areas and air defence identification zone (ADIZ)
- ENR 5.3.1 Other activities of a dangerous nature
- ENR 5.3.2 Other regulated airspaces
- ENR 5.5 Aerial sporting and recreational activities
AIXM Model Overview
The main class in this AIXM model is the Airspace class containing the basic data, such as the name and type of the airspace.
There are two main ways to describe the geometry of airspace volumes in AIXM 5:
- by providing a horizontal projection with vertical limits;
- by providing a composition rule by which the airspace is defined as a series of unions, intersections, subtractions of other airspace(s).
For the first option, the AirspaceVolume class with a related Surface or Curve (for airspace corridors) will be used for the encoding.
For the second option, the airspace composition will be encoded by using the AirspaceGeometryComponent class and if applicable (in case of airspace aggregation by reference) also the AirspaceVolumeDependency class.
The class of an airspace is encoded using the AirspaceLayer object. An airspace class may be defined for the whole airspace or layers of it.
Furthermore, within an airspace a Service may be provided by a Unit using one or more RadioCommunicationChannel.
Airspaces and the service provided by the ATS unit may operate under certain schedules.
For special activity airspaces, also information about the existing type of restriction or nature of hazard, activation process and/or time of activity may be provided using the AirspaceActivation class.
The figure below shows a simple example of a restricted area with the designator EAR7.
More coding examples can be found in the AIP Data Set - Specimen (DONLON).
