INFLUENCE OF WINDSHEAR, DOWNDRAFT AND TURBULENCE ON FLIGHT SAFETY
Wind shear, downdraft, and turbulence influences flight safety especially in take-off and landing approach. For a better understanding of the relevent problems, the typical aircraft response in gust and in wind shear will be pointed out and will be compared with real flight situations. In general the air-speed deviation of an aircraft in a wind shear situation is relatively small in contrast to flight path deviations and flight performance is not the limiting factor. Flight simulator studies have shown that it is difficult for the cockpit crew to identify a wind shear situation without any additional display of relevant information in order to control throttle and elevator in a correct manner. A wind shear warning display, based on energy deviation and energy rate can assist the pilot to overcome severe wind shear.
