According to PANS-AIM for VOR the specific station declination should be provided rather than the local magnetic variation. However, in many AIPs the magnetic variation is published instead.
Navaid Component
VOR/DME
A DME may be co-located with VOR. Such a VOR/DME will be coded as a Navaid.type equal-to 'VOR_DME', with two corresponding NavaidEquipment instances, a VOR and a DME.
For both NavaidEquipment the NavaidComponent.collocationGroup will be equal-to '1'.
If the VOR is the navigable location of the navaid when the navaid is used as significant point:
the NavaidComponent.providesNavigableLocation for the VOR will be equal-to 'YES' and the NavaidComponent.providesNavigableLocation for the DME will be equal-to 'NO'.
The VOR provides the bearing information, whereas the DME is used for the distance information.
