A VORTAC combines the VOR and TACAN in one location. Civil users will use the VOR signals which have the same performance as ordinary VOR signals. In addition they use the DME from the TACAN. Effectively a VORTAC is like a VOR/DME. Military users only use the TACAN, for them a VORTAC is the same as a TACAN.

A VORTAC (VHF Omni-directional Range/Tactical Air Navigation) combines a VOR ground station and a TACAN ground station into a single facility. If a VOR equipped aircraft is also equipped with a separate DME unit it will receive distance information between the TACAN ground station (at the single combined facility) and the aircraft.

Dec 26, 2017 · More details: A VORTAC station is composed of three signal generators: A VOR (VHF) signal used for civil bearing determination. A DME (UHF) signal used for range determination; An UHF signal used for military bearing determination, in theory 9 times more accurate than a VOR.

Oct 6, 2018 · They are DME (TACAN) channels. If you look close the the VORs, you'll see that they are either a VOR/DME or a VORTAC station. DME is the distance portion of a TACAN. When added to a VOR, you have a VOR/DME. If a complete TACAN is co-located with the VOR it is identified as a VORTAC. The military uses TACAN.

Dec 28, 2017 · The VORTAC indicator in the cockpit tells you which radial line connects your current location with the ground station you are tuned to in degrees referenced to local magnetic or true north. NDB broadcasts a signal which contains no direction information; the NDB indicator needle in your cockpit only tells you how many degrees left or right you ...

Feb 16, 2023 · So in your case, the V is a VOR approach without DME, the D includes DME and the S is for combined VOR/DME and TACAN (VORTAC). Similarly, the ILS I, L and B correspond to regular ILS, localizer and backcourse approaches respectively.

Nov 11, 2016 · That small dot is the approx. location of the VOR/VOR-DME/VORTAC on an airfield, should the airfield be so equipped. $\endgroup$ – Romeo_4808N Commented Nov 11, 2016 at 3:39

May 22, 2016 · PFN Vortac (decommissioned), source. Signals: A VOR transmits bearing information continuously. A TACAN sends reply pulse pairs when interrogated (see the explanation below). These pairs convey both bearing and distance information. A TACAN is usually more powerful than a VOR and has a larger range of use.
