In addition, information on system and means of activation announcements, together with information pertinent to civil flights and applicable ADIZ procedures shall be provided.
In AIXM 5 the AIrspaceActivation AirspaceActivation class will be used to define 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.
In addition, the activation status of the airspace, allowing to define if the restriction is active will be defined including timesheet information (see also topic Schedules for Airspace) including timesheet information.
The status might carry the following values:
| Status | Description |
|---|---|
| 'AVBL_FOR_ACTIVATION' | The feature may be activated. |
| 'ACTIVE' | The airspace is active (but it might not be in use yet). |
| 'IN_USE' | The airspace is actually used inside the activation period. |
| 'INACTIVE' | The airspace is not active. |
| 'INTERMITTENT' | The Airspace is active but with periods of no real usage. |
| 'OTHER' | Other. |
For the AIP data set the status should be coded with 'ACTIVE'.
In case of "announced by NOTAM", the status shall be 'AVBL_FOR_ACTIVATION' (.
In both cases a digital NOTAM issued, will override that status e.g. to 'ACTIVE' or 'IN_USE').
The restriction may be limited within the airspace to a certain vertical portion of airspace by using the AirspaceLayer class. The vertical limits of the airspace concerned may be defined by a certain upper and lower limit of the AirspaceVolume, which by a digital NOTAM may be limited to the actual AirspaceLayer used, which may be just a portion of its whole vertical extent .
Restrictions may also be limited to certain AircraftCharacteristics.
In addition, the system and means of activation announcements and ADIZ procedures may also be detailed using the RulesProcedure feature.
For information regarding risk of interception, a dedicated value 'INTERCEPTION_CIVIL_AIRCRAFT' is provided for the RulesProcedure.title attribute.

Coding Rules for Restriction & Activation of Airspace
| Identifier | Data Encoding Rule | Justification | Data Verification Rule (UID) | Remarks |
|---|---|---|---|---|
ASE-501 | The AirspaceActivation.activity attribute is mandatory for special activity airspaces and other regulated airspaces. | Minimum data | TBD | PANS-AIM requires the class of airspace as part of the minimum AIP data set only for special activity airspaces other regulated airspaces, not for ATS airspaces. |
| ASE-501 | The AirspaceActivation.status attribute shall carry either the value 'ACTIVE' or 'AVBL_FOR_ACTIVATION'. | Digital NOTAM Event Specification | TBD | A digital NOTAM issued, will override that status. |
