Intruder,
hmm - I don't disagree with anything you say in your discriptions regarding minimum sink and max glide, where you find them in speed terms or the applications thereof.
I just disagree with your assertion that minimum sink = maximum lift.
1.) Best Glide Speed = Best L/D ratio.
2.) Best L/D ratio = smallest descent angle.
3.) Smallest descent angle yields biggest possible value for lift in the equation L=W Cos (Angle Of Descent.)
Could you clarify which of points 1, 2 or 3 you feel is invalid and maybe we can thrash it out from there.
Cheers,
CPB.
