Hi HN39

Equation (9) in the paper referenced in post#27. It corresponds to a lift coefficient equal to √(Cd0/K)
I read that as an equation to calculate minimum drag speed. Maybe the way I phrased things, but I meant an equation to tell you at what lift coefficient two aircraft of differing weight could have the same L/D. Or am I missing something?
