Never exceed airspeed (VNE) is what?

Never exceed airspeed (VNE) is what?

• A. 135 knots
• B. 149 knots (145 KCAS)
• C. 142 knots
• D. 155 knots

Answer: (B)

VNE is the never-exceed airspeed, the highest speed at which the airframe has been proven to safely withstand flight loads. Exceeding it can cause structural damage or loss of control due to flutter, buffeting, or other limits of the airplane’s design. For this aircraft, the published VNE is 149 knots indicated airspeed, which corresponds to 145 KCAS. That pairing explains why the option showing 149 knots (145 KCAS) is the correct one: it matches the official limit, accounting for the instrument and calibration definitions. The other speeds are not the official maximum and would not be the published VNE.
