Where is Vne indicated on the airspeed indicator?

Vne, or the maximum allowable airspeed in a specified configuration of the aircraft, is indicated by the red radial line on the airspeed indicator. This red radial line serves as a critical marker that warns pilots not to exceed this airspeed, as doing so could lead to structural damage or loss of control. It is vital for pilots to be aware of this limitation to ensure the safety and integrity of the aircraft during various stages of flight.

The other areas on the airspeed indicator correspond to different airspeed ranges: the green arc indicates normal operating speeds, the yellow arc represents cautionary speeds where the aircraft may be more susceptible to turbulence, and the white arc denotes the flap operating range. While these ranges are important for safe operation, the red radial line explicitly marks the limit that should not be exceeded, reinforcing its significance as the indicator for Vne.
