Airspace activation

The figure below shows the main AIXM 5 classes used for the airspace activation concept, including relevant list of values for some properties.

The AirspaceActivation class is used to provide information about the status of the airspace (active/inactive) and eventually the type of activity (i.e. the primary situation or reason on the ground or in the air, which may have an impact on airspace usage) that takes place in the airspace.

The AirspaceActivation is derived from PropertiesWithSchedule, allowing to associate a schedule with the status and the activity properties, when necessary. In addition, it may also be associated with one or more AirspaceLayer, which allows to indicate that the activation concerns only some particular vertical bands.
