Vertical Speed Indicator(VSI)
Definition
An instrument showing rate of climb or descent in feet per minute by measuring the rate of pressure change. There is inherent lag in the VSI, with instantaneous VSI variants reducing this delay.
Why Vertical Speed Indicator Matters for Pilots
Instrument knowledge is tested on every pilot certificate exam. Understanding how Vertical Speed 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 Vertical Speed Indicator in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
