A wind tunnel investigation of the characteristics of turbulence encountered by STOL aircraft during steep descents was performed. The experimental results were used as input to a mathematical model of the linearized lateral equations of motion of a typical STOL aircraft, yielding the root-mean-square dispersion of the lateral state variables from a nominal flight path. Single and four point aircraft approximation were considered; the former accounting only for side gusts, and the latter including rolling, and longitudinal and lateral yawing gust gradients. The single-point approximation proved to be inadequate for estimating lateral dispersions from the glidescope. Dispersion contributions due to rolling, and longitudinal and lateral yawing gust gradients were separated for the four point approximation.
