What is classed as light turbulence?

• A. Rise or drop of 1 meter, hardly noticeable to passengers.
• B. Rise or drop of 5 meters, significant movement.
• C. No movement but wind speeds at the wing.
• D. Turbulence only occurs at high altitude.

Answer: (A)

Light turbulence means only a tiny, barely noticeable buffeting of the aircraft, with very small changes in altitude or attitude. Describing a movement that is hardly noticeable fits this level, so it’s the best match. The other ideas describe stronger effects or scenarios that aren’t turbulence in the light category: a larger vertical shift would be more than light, saying there’s no movement isn’t describing any buffeting, and turbulence can occur at many altitudes, not just high up.
