Which equipment is referred to as DME in aviation?

The term DME in aviation stands for Distance Measuring Equipment. This advanced navigation system is integral to aircraft navigation, providing pilots with precise distance information to a ground station. It works by measuring the time it takes for a signal to travel from the aircraft to the DME station and back. This time is then converted into distance, allowing pilots to gauge how far they are from the station, which is crucial for navigation, especially during approaches and landings.

Distance Measuring Equipment enhances situational awareness and aids in maintaining safe aircraft separation. It is a valuable tool for pilots, contributing to more accurate flight path management and helping ensure compliance with air traffic control instructions. In contrast, the other options presented do not represent established aviation equipment or terminology recognized in flight operations and navigation.
