Instrument Scan
Definition
The systematic cross-check of flight instruments during instrument flight. The radial scan uses the attitude indicator as the hub and cross-checks other instruments. Scan must be active, not fixated on one instrument.
Why Instrument Scan Matters for Pilots
Instrument knowledge is tested on every pilot certificate exam. Understanding how Instrument Scan 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 Instrument Scan in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
