Calculate g's per radian I'm currently attempting to assign handling qualities to the A-4D, and I would like to know how to find the term:

$ n / \alpha = \overline{q} \times C_{L\alpha} / (W / S) $

where $C_{L\alpha}$ is the lift-curve slope. I think I could solve for the lift-curve slope by using the value $1/T_{\theta2}$ or $1/T_{P2}$, the phugoid frequency, somehow, but I cannot find that equation.

I'm not given a chart of the change in lift-curve slope per Mach number.
The solution that I needed is the following image:
