Which of the following is NOT an intensity of turbulence?

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

Answer: (C)

Intensities of turbulence are defined by a formal scale used in aviation: Light, Moderate, Severe, and Extreme. Each term describes how much the air movement affects the aircraft and how noticeable it is to passengers. “Mild” isn’t part of that official scale, so it isn’t used in weather reports or pilot briefings as a separate intensity level. Since Light covers the lowest level of disturbance, calling something Mild would be ambiguous and not an accepted category. That’s why Mild is the correct choice for NOT being an official turbulence intensity. The other terms—Light, Moderate, Severe, and Extreme—are the standard categories.
