Global Positioning System(GPS)
Definition
A satellite-based navigation system providing precise three-dimensional position anywhere on Earth. GPS has become the primary means of navigation in modern aviation, enabling RNAV and RNP approaches.
Why Global Positioning System Matters for Pilots
Navigation concepts like Global Positioning System 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 Global Positioning System 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 Global Positioning System in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
