Which statement best describes severe turbulence?

Which statement best describes severe turbulence?

• A. It lasts only a few seconds.
• B. It causes large, abrupt changes in altitude/attitude and the aircraft may be momentarily out of control.
• C. It causes only minor, smooth changes in airspeed.
• D. It occurs only in winter months.

Answer: (B)

The main idea here is what defines severe turbulence. Severe turbulence involves large, abrupt changes in altitude or attitude that can throw the airplane around and may cause the aircraft to be momentarily out of the flight crew’s direct control. It’s more intense than light or moderate turbulence and can last for more than just a few seconds, depending on the atmospheric conditions. This description distinguishes it from milder forms, which produce only light or moderate bumps without the dramatic, rapid displacements or loss of control that severe turbulence can cause. It also isn’t limited to a particular season; strong turbulence can occur under a variety of weather conditions, such as convective activity, jet streams, wind shear, or wake from other aircraft. So the statement that best describes severe turbulence is the one that notes large, abrupt changes in altitude/attitude with the potential for the aircraft to be momentarily out of control.
