Hi!

Given that the slope for a finite and an infinite wing are different. I am not sure if the alfa/aoa range for both wings is the same?

I have books that the explain how to calculate the slope for a finite wing, but they do not mention if the range is the same? This is critical to be able to calculate CL max for a finite wing.
The only thing that the different slope lines equation share in common, is the same origin at alfa = 0. It is hard to tell if alfa at the end of the range, is the same for both equations?

Thanks in advance for your help!
