Magnetic Compass
Definition
The most basic navigation instrument, using a magnetized card to indicate magnetic heading. Subject to deviation, acceleration, and turning errors. Required as standby reference even in glass cockpit aircraft.
Why Magnetic Compass Matters for Pilots
Instrument knowledge is tested on every pilot certificate exam. Understanding how Magnetic Compass works helps you interpret cockpit information correctly and recognize instrument failures before they become emergencies. This knowledge is especially critical for instrument-rated pilots flying in reduced visibility.
Exam Tip
This concept is commonly tested in instruments-related questions on FAA and EASA exams. Make sure you can explain Magnetic Compass in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
