shear for aircraft. Low-level wind shear can affect aircraft airspeed during takeoff and landing in disastrous ways, and airliner pilots are trained to avoid all microburst wind shear (headwind loss in excess of 30 knot). The rationale for this additional caution includes:
*microburst intensity can double in a minute or less,
*the winds can shift to excessive crosswinds,
*40 - 50 knot is the threshold for survivability at some stages of low-altitude operations, and
*several of the historical wind shear accidents involved 35
