Often the [[VOR-DME]] part of the [[TACAN]] is also made available for civilian navigation. If so, the beacon is called a '''VORTAC''', but the use is as a normal [[VOR-DME]], in the normal frequency range. The range of the beacon varies. Most have the same range as a [[VOR-DME]] but many will have different ranges. | Often the [[VOR-DME]] part of the [[TACAN]] is also made available for civilian navigation.
