What does VOR/DME represent in aviation navigation?

• A. Only VOR is required
• B. Only DME is required
• C. Both VOR and DME are required
• D. Neither VOR nor DME is required

Answer: (C)

VOR/DME represents a combined system used in aviation navigation that provides both angular and distance information to pilots. Specifically, VOR stands for VHF Omnidirectional Range, which is a type of radio navigation system for aircraft. It allows pilots to determine their position and stay on course by receiving signals from ground-based VOR stations. DME stands for Distance Measuring Equipment, and it complements the VOR system by giving the pilot accurate distance information from the DME station. When VOR and DME are used together, they significantly enhance navigational accuracy. This combination enables pilots to obtain their exact position in three-dimensional space (both direction and distance), which is crucial for effective navigation, especially in instrument flight rules (IFR) conditions. Using only one of these systems—either VOR or DME—does not provide the complete situational awareness necessary for effective navigation. Therefore, relying solely on either a VOR signal or DME distance reading would limit pilots’ ability to navigate accurately. Hence, both VOR and DME being required underscores the value of having complementary navigation data, enhancing safety and efficiency in flight operations.
