VNO is Maximum Structural Cruising Speed per definition in CFR FAR Part
.... snip...

Of course VNE never-exceed speed is the tiny red arc and we
shouldn't go there!


That would be a red *line*, not a tiny red arc at all.

So tell me what is the definition of VNO?


The first line of your post is the definition; top of green arc is where it
is.
