What is the "Vno" speed?

The "Vno" speed, also known as the maximum structural cruising speed, is an important parameter in aviation safety. It represents the maximum speed at which the aircraft can be safely flown in turbulent air. Pilots should operate below this speed to maintain control and reduce stress on the airframe during potentially hazardous conditions. Exceeding Vno when encountering turbulence could lead to structural damage or loss of control, as the airframe is not designed to handle the forces that may be exerted on it at higher speeds in turbulent conditions.

The Vno speed acts as a guideline for the safe operation of the aircraft, ensuring that pilots remain within safe limits during cruise flight, particularly when turbulence is expected. Understanding this speed is crucial for maintaining both pilot and passenger safety in varied flying conditions.
