What does the term 'Vne' refer to in aviation?

The term 'Vne' stands for "velocity never exceed," which is the maximum speed that an aircraft should never exceed during flight operations. It is a critical airspeed displayed in the aircraft’s Pilot Operating Handbook (POH) or Airplane Flight Manual (AFM) and is represented by a red radial line on the airspeed indicator. Exceeding Vne can lead to structural failures or loss of control of the aircraft, especially under adverse conditions such as turbulence or sudden maneuvers. Therefore, pilots are trained to remain below this threshold to ensure the safety and integrity of the aircraft during flight operations. Understanding Vne is essential for pilots in maintaining operational limits and minimizing the risk of overstressing the aircraft.
