Which term represents the most severe turbulence level?

• A. Light
• B. Moderate
• C. Severe
• D. Extreme

Answer: (D)

Turbulence intensity is classified from light to extreme, and the highest category represents the most severe conditions. Extreme turbulence is described as violent, erratic changes in altitude and aircraft attitude, with large, abrupt movements that can be difficult to control and cause injuries if passengers and crew aren’t restrained. Since it denotes the greatest intensity on the scale, it is the correct choice for “the most severe turbulence level.” Light and Moderate involve smaller, more manageable motions, while Severe is strong and disruptive but not as extreme as the top category. Extreme turbulence is rare and represents the extreme end of the spectrum.
