Over one million hours of aircraft flight test data for loading factors in excess of 0.5 g were analyzed using three different methods in order to model coherent atmospheric turbulence. The Houbolt method (using a rigid body with two degrees of freedom for the aircraft flight mechanics) is found to provide a better description of the atmosphere than either the Pratt method (in which turbulence values are obtained from the vertical acceleration of the aircraft) or the Hall method (using only a single degree of freedom for the aircraft motion). The Houbolt method is improved by a calibration using exact calculations for a small number of different aircraft configurations.
