UNRESOLVED ISSUES IN WIND SHEAR ENCOUNTERS.

Much remains to be learned about the hazards of low-altitude wind shear to aviation. New research should be conducted on the nature of the atmospheric environment, on aircraft performance, and on guidance-and-control aids. In conducting this research, it is important to distinguish between near-term and far-term objectives, between basic and applied research, and between uses of results for aircraft design or for real-time implementation. Advances in on-board electronics can be applied to assuring that aircraft of all classes have near-optimal protection against wind shear hazards.
