Stall speed approaches TAS at altitude. I think that is one reason why the big boys use Mach numbers and stick shakers. Now I said more than I know. Maybe the military and heavy iron guys can chime in.

Actually, I'm talking about flutter. VNE (for our homebuilt purposes) seems to be that IAS at which the designer who almost certainly hasn't gone into it too very deeply, begins to perceive that he is on the cusp of being uncomfortably close to it. Flutter that is. It's on that page in the POH that even SMELLS like it's been pulled out of someone's ass :o)
I think I'll get some sleep ... Jim S.
