A description is given of atmospheric turbulence and its spectral characteristics with emphasis placed on the application of this information to the aircraft equations of motion. The gust model developed accounts for not only the effect of body axis gust velocities applied at the center of gravity, but also includes the effect of gust gradients along the length and span of the aircraft. The latter effect is usually neglected but can be quite significant with small aircraft at high speeds. Thus, the model varies as a function of both aircraft size and velocity. An analog and digital model is developed for use with large-scale aircraft simulations or less sophisticated linearized aircraft models. Author
