There has to be a clear line-of-sight with the beacon. If there are mountains or other obstructions the VOR signal can not be received. | There has to be a clear line-of-sight with the beacon. If there are mountains or other obstructions the VOR signal can not be received. | ||
While it is more expensive to operate a VOR station compared with a NDB the benefits are obvious. The signal is less hindered by unwanted reflections and other interferences, it takes away confusion about North | While it is more expensive to operate a VOR station compared with a NDB the benefits are obvious. The signal is less hindered by unwanted reflections and other interferences, it takes away confusion about North, since it's oriented to True North, it can be used for automated flight and the receivers are more reliable. | ||

A DME tells the equipment on board of the aircraft the distance towards the transponder. | [http://en.wikipedia.org/wiki/Distance_measuring_equipment Distance Measuring Equipment ('''DME''')] uses the same frequencies as a VOR.
