DME Arc
Definition
A curved instrument approach segment flown at a constant DME distance from a VOR/DME station. Requires continuous adjustment of heading to maintain the arc distance while transitioning to the final approach course.
Why DME Arc Matters for Pilots
Navigation concepts like DME Arc 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 DME Arc 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 DME Arc in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
