Final Approach Knot Wind Shear

Flight Characteristics The Piper Seminole has predictable handling characteristics, but its twin-engine nature demands more precision during the approach phase. Approach speeds typically range from 80 to 90 knots depending on weight and flap settings, while full flaps are often used to provide the necessary lift during landing.

The mechanical force is via the wind velocity and direction. Wind velocity of greater than 20 knots with higher gusts, especially flowing over rough terrain, can lead to an unwelcome flight. As we got crossed the final approach fix, the rain shaft grew. I looked at the airspeed and it was jumping +/-5-10 knots.

I intercepted the approach course and after a few moments, reached the final approach fix at JUNIA. I pulled the power back and set a notch of flaps to establish a 90 knot, 500 foot/minute descent. My clever plan was to beat it, but the rain was faster and arrived early. At least there were no witnesses.

Considering the delay in the AWOS reporting, it may also be helpful to proactively use the radio to ask anyone on the ground for the current winds (e.g. Microbursts are not the only source of severe wind-shear close to the ground. Sudden and very powerful surface winds can have various other causes. the local FBO).

Seconds later, now within 50 feet of the ground, the turbulence completely vanished, granting us a steady, moderate wind straight down the runway, and allowing us our standard over-the-fence speed of 65 knots, a gentle flair, and a greased on landing like Dad had done countless times on our little airstrip in St. Peter, Wisconsin.

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.

A go-around is a maneuver performed to abort or reject a landing on the final approach or once the aircraft has already touched down. 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.
