Abstract : A statistical analysis is presented of gust environment based upon recorded experience of fleet aircraft on routine, low-altitude training flights. Discrete gust data are also presented as probability density distributions of the rootmean-square gust velocity. On the basis of data gathered to date, correlation of atmospheric turbulence with topography and meteorological data has been limited to comparing flights over two geographical areas. Definite gust-environment patterns are evident. Cold, winter days with unlimited ceiling, permitting maximum solar radiation, appear to produce intense turbulence on the cross-country flights in the southeastern United States. Low-altitude gust intensity and frequency is a function of ambient temperature over flat desert terrain on days of unlimited ceiling and 15-mile visibility. (Author)
