  winds near the surface can be as strong as 45 knots resulting in a 90 knot shear (headwind to tailwind change for a traversing aircraft) across the microburst. These strong horizontal winds occur within a few hundred feet ... this is followed in short succession by a decreasing headwind component (2), a downdraft (3), and finally a strong tailwind (4), where 2 through 5 all result in decreasing performance of the airplane. Position (5) represents an extreme situation just…

  increases, causing an airspeed increase. • Decreasing Headwind Shear: Wind shear in which headwind decreases, causing an airspeed decrease. • Decreasing Tailwind Shear: Wind shear in which tailwind decreases, causing an airspeed increase. • Increasing Tailwind Shear: Wind shear in which tailwind increases ... addition, the magnitude of the shear depends on the flightpath through the microburst. An increasing headwind (or decreasing tailwind) shear increases indicated airspeed and thus increases performance. The airplane will tend to pitch up to regain trim airspeed. An additional…
