The roots of the characteristic equation for the longitudinal dynamics of a certain aircraft are:
λ1 = -0.02 + 0.2i
λ2 = -0.02 - 0.2i
λ3 = -2.5 + 2.6i
λ4 = -2.5 - 2.6i
where i = √-1. The short period damped frequency is
λ1 = -0.02 + 0.2i
λ2 = -0.02 - 0.2i
λ3 = -2.5 + 2.6i
λ4 = -2.5 - 2.6i
where i = √-1. The short period damped frequency is
Correct : a
