Should you exceed VNO in smooth air when flying with retractable landing gear?

• A. It may be exceeded only in smooth air.
• B. VNO is the red line on the airspeed indicator.
• C. You should always stay below VNO in all conditions.
• D. Do not exceed VNO except in smooth air.

Answer: (D)

The item tests how airspeed limits relate to air quality. VNO is the maximum structural cruising speed—the speed at which the airframe is designed to handle routine flight loads. In smooth air, the airplane can tolerate higher dynamic pressures, so you may operate above VNO, up to the so-called never-exceed speed (VNE). But in rough air or turbulence, you should not push beyond VNO to avoid overloading the structure. With retractable landing gear, the same principle applies; gear configurations introduce different limits (like gear-down speeds), but the rule about exceeding VNO only in smooth air remains the guiding guideline. So, you should not exceed VNO except in smooth air.
