In a VOR/DME navigation setup, what does DME provide?

• A. Distance to the VOR station
• B. Bearing to the VOR station
• C. Altitude above the VOR station
• D. Vertical speed to the VOR station

Answer: (A)

DME provides distance. In a VOR/DME setup, the VOR supplies the bearing (the direction) to the station, while the DME measures how far you are from the DME transmitter. It works by timing the signal as it travels to the aircraft and back, giving a distance in nautical miles. That distance is the slant range to the station, not altitude or vertical speed. So the DME readout tells you how far you are from the VOR/DME facility, which is the key piece for positioning along a chosen course.
