where Kp, Ki, and Kd are the controller gains.

Therefore, the aircraft is laterally stable.

SM = (xcg - xnp) / c

Substituting the given values, we get:

∂m / ∂α < 0

Substituting the given values, we get:

The controller can be designed using the following transfer function: Flight Stability And Automatic Control Nelson Solutions

For directional stability, the following condition must be satisfied:
