So now im confused! this is all off the previous link, and says VNE is IAS
Flight at airspeeds outside the envelope (or at inappropriate speeds in turbulent conditions, or when applying inappropriate control loads at high speed) is high risk and can lead to airframe failure. Vne is the IAS, specified by the designer, which should never be intentionally exceeded
Vne for light aircraft is always specified as an indicated airspeed and marked as such on the ASI (the red line). For most ultralight aircraft, only one Vne is specified in the Pilot's Operating Handbook or aircraft flight manual and that value is probably conservative and applicable for operations below 10 000 feet amsl. However, some ultralight aircraft have a capability for achieving considerable altitude and the designers have felt it wise to limit maximum speed to a particular true air speed.
For most recreational light aircraft only one Vne is specified in the Pilot's Operating Handbook or aircraft flight manual. That value is probably conservative and applicable for operations below 10 000 feet amsl. The designers of most piston-engined GA aircraft specify one fixed-value Vne for operations up to the service ceiling; that value is represented by the fixed red line on the ASI. However, a minority of GA aircraft have supplementary lower-value Vne for operations in altitude bands above a stated altitude — perhaps above 10 000 or 15 000 feet. This approach to Vne specification is common with sailplanes.
A very few aircraft designers select a true air speed value as a limiting airspeed applicable from sea level. FAR Part 23.1545 © requires that "If Vne varies with altitude, there must be means to indicate to the pilot the appropriate limitations throughout the operating altitude range"
