The Effects of Wind Shear on Automatic Landing.

Abstract

Automatic approaches and landings are simulated on a hybrid computer in constant winds, linear wind shear, logarithmic wind shear and knife-edge wind shear to determine the effects of wind shear on automatic landing. The aircraft is modeled by the longitudinal equations of a large jet transport with a typical autoland system. Results identified large differences in performance in the three types of shear, with large touchdown dispersions in moderate logarithmic wind shears. Analysis indicated that performance in logarithmic wind shear was strongly dependent on airspeed deviations. (Author)
