What two components are combined in VORTAC?

• A. DME and GPS
• B. VOR and GPS
• C. VOR and DME
• D. ILS and VOR

Answer: (C)

VORTAC combines a VOR with DME. The VOR portion provides azimuth information, giving you your bearing relative to the station through a set of 360 radials. The DME portion gives distance information by measuring how long signals take to travel between your aircraft and the station, usually reported in nautical miles. With both bearing and distance, you can determine your exact position relative to the VORTAC and navigate along routes or approaches that rely on those readings. GPS is a separate system and not part of VORTAC, and ILS is a different approach system, so the combination you get in VORTAC is bearing plus distance from the station.
