Analysis and Specification of Slant Wind Shear.
Abstract
Wind data have been analyzed to produce frequencies of occurrence of slant wind shear with respect to surface wind speed, time of day, vertical temperature gradient and wind shear direction differences. Slant wind shear (SWS) is a measurement that more closely approximates the shear encountered by an aircraft on takeoff or landing. It is computed as the wind shear between a higher level wind (in this study, 60 m) and the surface separated by a horizontal distance equivalent to that which an aircraft would traverse in descending or ascending that height. Additional study was also completed on the specification of slant wind shear along the runway through the use of an offset towersurface site system.
