Which of the following are levels of turbulence intensity?

The classification of turbulence intensity is essential for pilots and aviation professionals to assess and communicate the severity of turbulence encountered during flight. The correct answer includes "Light, Moderate, Severe, Extreme," which aligns with standardized definitions used in aviation.

Light turbulence is characterized by slight, erratic changes in altitude and/or attitude of the aircraft that may not be uncomfortable for passengers. Moderate turbulence is more pronounced, causing changes in altitude and/or attitude that may result in noticeable strain on unsecured objects. Severe turbulence is intense enough to cause abrupt changes in altitude and/or attitude, making it difficult for pilots to control the aircraft. Extreme turbulence is the most intense level, resulting in violent, erratic movements that can cause structural damage to the aircraft and severe discomfort to passengers.

The other answer choices use terms that do not match the established definitions recognized in aviation. For example, "Weak" and "Dangerous" do not correspond to official categories and could lead to misunderstandings regarding the nature and appropriate response to turbulence. Similarly, terms like "Heavy" and "Critical" lack standardization when discussing turbulence intensity and would not effectively communicate the conditions of flight.

In summary, understanding these levels is crucial for assessing flight safety, making the correct choice of "Light, Moderate,
