Magnetic Variation
Definition
The angular difference between true north and magnetic north at a given location. Also called magnetic declination. East variation is subtracted from true heading, west variation is added.
Why Magnetic Variation Matters for Pilots
Navigation concepts like Magnetic Variation 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 Magnetic Variation 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 Magnetic Variation in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
