Ian, "The Real Doctor" *Out of curiosity, what exactly do you have a

Numerical solution of non-linear diffusion problems.Which is actually
a lot more interesting than it sounds.

I can even rearrange the equations in set 1 and get the same
relationships. So, what in the world am I missing when I say Lift =
Weight * cos (glide angle)?

Sorry, it was late. I misread, and thought you'd done the old W = L cos
(theta) mistake (W, of course, = L cos(theta) + D sin(theta).

My apologies.
