What are the three intensities of turbulence?

• A. Light, Moderate or Severe.
• B. Mild, Moderate, Severe.
• C. Low, Medium, High.
• D. Gentle, Strong, Extreme.

Answer: (A)

Intensities of turbulence are described in three levels: light, moderate, and severe. Light turbulence causes only small, momentary deviations in altitude or attitude with minor discomfort. Moderate turbulence produces more noticeable changes and may require a steadying grip and some airplane control inputs, but the aircraft stays in control. Severe turbulence brings large, abrupt changes in altitude and attitude and can make control challenging, often prompting stronger corrective actions from the crew. Some sources add an extreme level, but in most practical contexts the three primary categories are light, moderate, and severe. Other term sets like mild/low-medium-high or gentle/strong/extreme aren’t the standard classifications.
