# Why are airspeed gauges labeled above Vne?

Examples:

Is the extra range deliberate? Is there a use for it?

Is this specific to Cessna models? I browsed instrument panel photos and didn't find a non-Cessna example. For most aircraft, it seems the range extends past Vne only to the next convenient round number.

• The fact that you should not exceed $$V_\mathrm{ne}$$, does not mean you never actually do. It would be good to know by how much you are currently exceeding it, so you can decide how to react to this situation.
• Not every aircraft model gets their own specific gauge. Cessna probably has a few gauges available and put the one with the smallest extra room above $$V_\mathrm{ne}$$ on the aircraft. This is quite similar to cars, where you get the same speedometer on most models of a car, despite having different engines and thus different maximum speeds. It is simply cheaper to produce (and certify) only a few different airspeed indicators.
• The aircraft's $$V_\mathrm{ne}$$ might change with modifications installed at a later time (like an aerodynamic upgrade package). It would be nice, if the avionics would not need to be exchanged for this.
