VS1
Definition
The stall speed or minimum steady flight speed in a clean configuration with flaps and gear retracted. Indicated by the lower limit of the green arc on the airspeed indicator.
Why VS1 Matters for Pilots
Performance planning directly affects flight safety. Knowing how VS1 works helps you calculate whether a takeoff or landing is safe for given conditions. FAA and EASA exams frequently test performance concepts, and examiners expect you to apply VS1 to real-world scenarios during oral exams and checkrides.
Exam Tip
This concept is commonly tested in performance-related questions on FAA and EASA exams. Make sure you can explain VS1 in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
