The NavaidOperationalStatus class carries two attributes:
The signalType attribute indicates may be used to indicate the type of information transmitted by a navaid or other radio emission source (e.g. azimuth or distance) .

The operationalStatus indicates the state of the navaid:
| Value | Description |
|---|---|
| 'OPERATIONAL' | Operating normally. |
| 'UNSERVICEABLE' | Not available. |
| 'ONTEST' | On test, do not use. |
| 'INTERRUPT' | Expect interruptions of the signal. |
| 'PARTIAL' | Operating with limited capabilities. For example, used when just the DME part of a VOR/DME is working. |
| 'CONDITIONAL' | Operative subject to published limitations or conditions. |
| 'FALSE_INDICATION' | Giving false indication, do not use. |
| 'FALSE_POSSIBLE' | False indication possible, use with caution. |
| 'DISPLACED' | Displaced |
| 'IN_CONSTRUCTION' | In Construction |
| 'OTHER' | Other |
For the AIP data set the default value for the hours of operation for a navaid will be 'OPERATIONAL'. Most of the others status are only relevant for an application of the Digital NOTAM concept.

In addition, although not required by PANS-AIM for the minimum AIP data set, the NavaidEquipmentMonitoring class is used to define if the navaid equipment is monitored ('YES') or not ('NO'). Corresponding Timesheet may be used to define the corresponding time constraints.
For details of how to encode the Timesheet see topic Common coding patterns.
