Can cause sudden losses or gains in indicated airspeed (IAS), directly affecting lift. Headwind component (Vf), either on the face or tail, is calculated with the cosine function. – A negative value indicates tailwind. . – A negative value indicates tailwind.

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. Without knowing the horizontal wind direction and speed at this point it is impossible to say what his indicated airspeed was. He expedited his landing trying to fly out of what was likely epic sink.
