What does DME in TACAN stand for?

DME in the context of TACAN stands for Distance Measuring Equipment. This system is crucial in aviation for providing the distance between an aircraft and a ground station. The DME works by using a series of radio signals, allowing pilots to determine their distance from the TACAN station, which aids in navigation and positioning during flight. This technology enhances situational awareness and supports safe and efficient navigation, especially in complex airspace.

The other terms presented do not accurately reflect the established terminology used in aviation. Understanding DME's role within the TACAN system is essential for anyone involved in aviation operations or maintenance, as it underlines the importance of distance measuring in flight safety and navigational accuracy.
