Vno (Maximum Structural Cruising Speed)

The maximum speed for normal operations, marking the boundary between the green and yellow arcs on the airspeed indicator. Flight above Vno and below Vne (the yellow arc, or caution range) is permitted only in smooth air, as encountering turbulence or making abrupt control inputs at these speeds could overstress the airframe. Pilots should reduce speed to at or below Vno when turbulence is encountered or expected.
