Abstract : A brief review is made of where we stand presently with respect to our understanding of aircraft encounter of atmospheric turbulence, both from the point of view of describing or modeling the turbulence and with respect to our ability to calculate the resulting airplane loads. Some of the more recent studies of gust measurements and of reducing airline gust response data are discussed. Special attention is given to gust analysis requirements as involved in airplane certification and whether there is a need for additional or different requirements. The paper concludes with the review of a recent study in which amazingly simple and universal gust response equations were discovered; the possible impact of these new findings on future work is indicated.
