Distance Measuring Equipment(DME)
Definition
A radio navigation system that measures the slant range distance between an aircraft and a ground station. DME is often co-located with VORs to provide both azimuth and distance information.
Why Distance Measuring Equipment Matters for Pilots
Navigation concepts like Distance Measuring Equipment are tested on instrument rating exams and are essential for safe cross-country flying. Whether you are planning a VFR flight or navigating under IFR, a solid understanding of Distance Measuring Equipment ensures you can find your way accurately and efficiently.
Exam Tip
This concept is commonly tested in navigation-related questions on FAA and EASA exams. Make sure you can explain Distance Measuring Equipment in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
