What is the maximum structural speed (Vno) for the aircraft?

The maximum structural speed, commonly referred to as Vno, represents the maximum speed at which an aircraft can safely be flown in turbulent air. For the Cessna 152, this speed is critical for ensuring the aircraft remains within its structural limits during flight. At Vno, the aircraft is capable of enduring mild to moderate turbulence without risking structural damage or excessive stress on the airframe.

This specific speed is typically marked by a yellow radial line on the airspeed indicator, indicating that operations above this speed should be done with caution, particularly when encountering turbulence. The value of 111 KIAS for Vno is established based on the aircraft's design and tested performance limits, ensuring that pilots remain aware of the need to operate within safe speed envelopes.

Understanding Vno is vital for pilots during various phases of flight, especially in conditions where turbulence may be present. This speed allows for the protection of the aircraft structure while providing operational flexibility. The given value aligns with the aircraft's operational performance characteristics recognized during training and documentation for the Cessna 152.
