Which navigation facility consists of VOR and TACAN components and provides VOR azimuth, TACAN azimuth, and TACAN distance (DME) at one site?

• A. VORTAC
• B. VOR
• C. TACAN
• D. VOR/DME

Answer: (A)

A facility that blends VOR and TACAN at the same site gives you everything needed for both civil and military navigation: the VOR portion provides the primary azimuth for civilian use, the TACAN portion provides a separate azimuth for military navigation, and the TACAN/DME system supplies the distance to the station. That combination—VOR azimuth, TACAN azimuth, and DME distance from one location—is exactly what a VORTAC delivers. The other options lack one of these elements: a VOR alone has only civil azimuth; a TACAN alone has military azimuth and DME but no civil VOR azimuth; VOR/DME has VOR azimuth and DME but not the TACAN azimuth.
