Heading Indicator(HI)
Definition
A gyroscopic instrument showing aircraft magnetic heading without the oscillation errors of a magnetic compass. Must be periodically aligned with the magnetic compass due to precession drift.
Why Heading Indicator Matters for Pilots
Instrument knowledge is tested on every pilot certificate exam. Understanding how Heading Indicator 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 Heading Indicator in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
