VNO

Definition

Maximum structural cruising speed, the upper limit of the green arc on the airspeed indicator. Above VNO (in the yellow arc), flight should only occur in smooth air.

Why VNO Matters for Pilots

Performance planning directly affects flight safety. Knowing how VNO 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 VNO 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 VNO in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
