What does the abbreviation DME stand for in navigation?

The abbreviation DME stands for Distance Measuring Equipment. This system is commonly used in aviation navigation to determine the distance of an aircraft from a specific ground station. DME works in conjunction with VOR (VHF Omnidirectional Range) stations, allowing pilots to receive precise distance information, which is critical for navigation, especially during approach and departure procedures.

Understanding DME is essential for pilots as it aids in maintaining situational awareness and ensures accurate reporting of distances to air traffic control. This capability allows for safer, more efficient flight paths and assists in adherence to airspace regulations.

The other options do not accurately describe the function or purpose of DME, making them less relevant in the context of aviation navigation.
