Substituting the given values, we get:

The controller can be designed using the following transfer function:

where xcg is the center of gravity, xnp is the neutral point, and c is the chord length.

Clβ = ∂l / ∂β

The autopilot system can be tuned by adjusting the controller gains to achieve stable and accurate altitude control.

∂m / ∂α < 0

-0.05 < 0
