Ground Speed
Definition
The actual speed of the aircraft over the ground, determined by true airspeed modified by wind. Ground speed affects fuel burn over distance and estimated time of arrival calculations.
Why Ground Speed Matters for Pilots
Navigation concepts like Ground Speed 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 Ground Speed 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 Ground Speed in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
