During the past fifteen years the Dynamics Department at BAe Weybridge have carried out a number of detailed investigations into a wide range of gust design procedures, varying from discrete gust to continuous turbulence on a number of different aircraft. As a result of a study into a unified procedure for meeting power spectral density and statistical discrete gust requirements for flight in turbulence, it was recommended that additional flight measurement evidence on the structure of high intensity turbulence events needed to be obtained on a more routine basis in order to support the gust parameters used in gust prediction procedures. Thus in the early eighties it was agreed by the Civil Airworthiness Authority (CAA) and BAe that a reassessment of the gust statistics should be undertaken together with a study of turbulence events taken from routine operational flights. The first part of the contract was to reassess the American and British gust statistical data. This data was collected in the most part prior to 1950 and formed a large part of the gust probability information upon which the current discrete gust airworthiness requirements are based. Whereas the second part was set to re-assess the current high vertical acceleration response data and routine data from the CAA Data Recording Programme (CAADRP) as has been measured upon the BAC 1-11 500 Series on standard airline routes.
