What does "Vne" represent in aviation terms?

In aviation, "Vne" refers to the Never Exceed speed, which is a critical parameter for the operation and safety of an aircraft. This speed is denoted on the airspeed indicator by a red radial line, and it indicates the maximum speed that should never be exceeded during flight. Exceeding this speed can lead to severe aerodynamic consequences, such as structural failure or loss of control of the aircraft.

Understanding Vne is essential for pilots to ensure they operate within safe speed limits, particularly during maneuvers or conditions that may invite risk. This parameter helps to establish safety limits for pilot training, flight planning, and operational procedures, thereby mitigating the likelihood of accidents related to high-speed operations.
