Introdution & PANS-AIM Reference
PANS-AIM requires some as part of the minimum AIP data set the hours of operation for radio navigation aids (for both enroute and terminal radio navigation and landing aids).
The diagram below shows the AIXM classes, including the relevant data types and code litslists, needed to encode that information.
...
As a general rule the availability of a NavaidEquipment should only be coded in case of a navaid is composed of more than one navaid equipmentsequipment, whereas at least one of them has a different availability than the others. If for one navaid equipment the availbility is coded, the availability has to be coded for all other navaid equipments of that navaid. For the navaid itself no availability will be coded. E.g. for a VOR/DME, in case the DME and VOR have different working hours, the availability will be ecoded for both navaid equipments separately, but not for the navaid).

| In case a navaid is not operational H24, the rest of the time it shall be coded as unservicable? Rule to be added? |
In addition, altough 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 Schedule [TSH]).

| Identifier | Data Encoding Rule | Justification | Data Verification Rule (UID) | Remarks |
|---|---|---|---|---|
| NAV-501 | Either the availability of the Navaid or the avalability availability of all the instances of NavaidEquipment the Navaid is composed of is mandatory. | Minimum AIP Data set | TBD | |
| NAV-502 | The availability of a NavaidEquipment shall only be coded in case of a Navaid composed of more than one NavaidEquipment, whereas at least one of them has a different availability than the others. | Data consistency | TBD | See open question above |
| NAV-503 | If for a Navaid composed of more than one NavaidEquipment, the availability of one of its NavaidEquipment is coded, the availability shall be coded for all other NavaidEquipment instances of that Navaid as well. | Data consistency | TBD | See open question above |
| NAV-504 | If a Navaid is composed of more than one NavaidEquipment, the availbilty is coded for the instances of NavaidEquipment are not exactly the same the availabililty of the Navaid shall not be coded. | Data consistency | TBD | See open question above |
| NAV-505 | If a Navaid is composed of one single NavaidEquipment the availability shall only be coded for the Navaid, | Data consistency | TBD | See open question above |
| NAV-506 | If a Navaid is composed of more than one NavaidEquipment all having exactly the same availability, the availability shall only be coded for the Navaid, (it is not necessary to copy it for each instance of NavaidEquipment). | Data consistency | TBD | See open question above |
