VREF(Vref)
Definition
Reference landing speed, typically 1.3 times VS0 for the landing weight and configuration. The target speed crossing the runway threshold to ensure adequate margin above stall.
Why VREF Matters for Pilots
Performance planning directly affects flight safety. Knowing how VREF 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 VREF 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 VREF in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
