Altimeter
Definition
A barometric instrument measuring altitude by sensing atmospheric pressure changes. Requires proper setting to display correct altitude. Errors increase with distance from the pressure setting source.
Why Altimeter Matters for Pilots
Instrument knowledge is tested on every pilot certificate exam. Understanding how Altimeter 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 Altimeter in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
