What does Vno stand for in aviation?

Vno, or maximum structural cruising speed, is a crucial airspeed for pilots as it indicates the maximum speed at which the aircraft can be safely flown in turbulent air. This speed is typically marked by the green arc on a typical aircraft airspeed indicator, and exceeding it can result in structural damage if the aircraft encounters turbulence, as it may not be able to withstand the aerodynamic forces at higher speeds. Pilots need to stay within this speed to ensure safety during normal flight operations and while maneuvering in varying atmospheric conditions. Knowing and respecting Vno is essential for maintaining the integrity of the aircraft's structure and ensuring a safe flying experience.
