Which statement about VORTAC is true?

• A. VORTAC integrates VOR azimuth, TACAN azimuth, and TACAN distance (DME) at a single site.
• B. VORTAC provides only VOR azimuth.
• C. VORTAC provides only TACAN azimuth and no DME.
• D. VORTAC is a GPS augmentation system.

Answer: (A)

VORTAC is a single ground-based navigation facility that provides both direction and distance information from one site. The VOR portion delivers the azimuth reference, showing you which radial to fly from the station. The TACAN portion supplies its own azimuth reference as well as distance information through DME (Distance Measuring Equipment). Because they’re co-located, a pilot can obtain VOR azimuth guidance and DME distance from the same site, combining the VOR and TACAN/DME functions at one location. That’s why the statement saying it integrates VOR azimuth, TACAN azimuth, and TACAN distance (DME) at a single site is true.

It’s not just VOR azimuth, nor just TACAN with no DME, and it isn’t a GPS augmentation system, which is why the other options aren’t correct.
