Microburst wind shear has been directly or indirectly involved in 28 aircraft incidents or accidents since 1964. Following the last major aircraft accident attributed to microburst wind shear in 1982, a major effort was undertaken to study the hazard. The majority of the work that has been accomplished deals with the publicity of the phenomenon to the aviation community and with acceptable methods of detecting it before it occurs. This study explores the background, detection systems and special considerations of helicopter operations in relation to microburst induced wind shear. Included are subjective hazards, aircraft response and recommended pilot actions to successfully penetrate the wind shear if inadvertently encountered. The study recommends that it be used as an interim measure to supplement existing microburst wind shear information and that additional helicopter microburst testing be conducted. Author
