Which statement is true about turbulence intensities within the set?

• A. There are four levels: Low, Medium, High, Severe
• B. There are two levels: Light, Heavy
• C. There is only one level: Moderate
• D. There are three levels: Light, Moderate, Severe

Answer: (D)

Turbulence intensity in aviation is defined across four levels: Light, Moderate, Severe, and Extreme. These categories describe how strongly the air forces the aircraft to bounce and how it affects passengers and crew, guiding how crew secure the cabin and respond. A three-level set leaves out Extreme, which is a recognized category for the most intense, sustained turbulence, while the four-level set uses standard terminology (Light through Extreme) to communicate severity consistently. Some four-level descriptions also use different labels, but the accepted set in flight operations includes Light, Moderate, Severe, and Extreme.
