| NAV-501 | Either the availability of the Navaid or the 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 | TBDSee 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 | TBDSee 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 | TBDSee open question above |
