Default Vne

Ehhhhhhh no. In our very sub supersonic world Vne is based on how fast the molecules actually go over the wing, which is the contributing factor to flutter. That's Vne, more specifically, it's given as a True Air Speed because that's the actual speed against molecules. Now what DOES change is the indicated speed for Vne, since IAS is a function more of HOW MANY molecules are getting rammed into the pitot tube. It's important to know those numbers as you descend out of wave. Vne as marked on the gauge red line is invalid up at the higher altitudes. Flying out west up high it may be more like 110kts indicated when the TAS is actually at redline.
