By basic principles of modern system theory, variances, or rms values of aircraft variables are calculated in the case where system dynamics and statistical properties of the disturbing signals, e.g., atmospheric turbulence, are a function of time. Properties of transient and steady state covariance response are summarized while the required format of aircraft and turbulence filter equations is given. Results are shown for numerical example of the symmetric motions of a jet transport in a coupled approach, followed by an automatic landing, the airplane being perturbed by Gaussian atmospheric turbulence. An example is also treated of transient variance response in which the variance overshoots the steady state value. The possible effects of the choice of initial conditions on the results of a stepwise covariance propagation calculation are elaborated.
