Headwind component (Vf), either on the face or tail, is calculated with the cosine function. Vf = Vw x cos() The result will give the intensity in knots (KT) and the sign will give the direction: – A positive value indicates headwind (headwind). DC = arctan(TAS/Vc) Where TAS is the True Airspeed.

Missing its tail, pointing almost straight down, a Van’s RV-7A single-engine, two-seat homebuilt plummeted out of the blue and into the rocky ground. This wasn’t the first Van’s homebuilt to experience an in-flight tail separation. In most cases, some type of aerobatics with an increase in airspeed preceded loss of control.

The Rifle ASOS recorded a gust of 43 mph from the south: a 100-degree shift in direction, putting it right on his tail. This is consistent with Rick’s report, which referenced 9 knots of wind. The Rifle ASOS recorded a gust of 43 kt from the south: a 100-degree shift in direction, putting it right on his tail.”
