Bumpiness with slight erratic changes altitude indicates which turbulence category?

• A. Light Turbulence
• B. Moderate Turbulence
• C. Severe Turbulence
• D. No Turbulence

Answer: (A)

Turbulence intensity is described by how much the aircraft shakes and how much the altitude changes. The description “bumpiness with slight erratic changes in altitude” fits Light turbulence, which is noticeable and occasionally bumps the airplane, with small and irregular altitude changes that aren’t dangerous or unsettling for the crew. Moderate turbulence would involve more pronounced changes in altitude and attitude and a greater sense of instability. Severe turbulence would produce large, abrupt movements and possible loss of control of the aircraft. No turbulence means a smooth ride with no bumpiness at all.
