Descent Knot Wind Shear 
Chess In the Air
JUNE 24, 2022
Moderate wind shear in some areas could make some thermals somewhat difficult to work but that, too, is typical. Between 5:10 and 5:34 PM, Rifle’s AWOS system reported light winds out of the west in the range of 4 to 9 kts (see chart below) with no wind gusts. Some passing high clouds were unlikely to be a factor.

Weather Go-arounds due to weather occur due to wind shear caused by gusting winds or microbursts. When an aircraft encounters horizontal wind shear, it could be blown off centerline. Similarly, if an aircraft encounters vertical wind shear, it reduces or increases the sink rate.

I pulled the power back and set a notch of flaps to establish a 90 knot, 500 foot/minute descent. As usual, the field AWOS (automated weather observation system) lied its nonexistent ass off with a declaration of five knot winds.
