When turbulence causes a significant change to altitude, it is referred to as?

The term used to describe a significant change in altitude due to turbulence is moderate turbulence. In aviation, turbulence is classified into several categories based on its intensity and the effects it has on the aircraft. Moderate turbulence is characterized by more frequent and noticeable altitude changes that can require pilots to make adjustments to maintain control of the aircraft.

When turbulence is classified as moderate, it generally means that it can cause abrupt changes in altitude or attitude, lead to strain on the aircraft and discomfort for passengers, and may require the pilots to make control inputs. Understanding this classification helps pilots manage turbulence effectively and ensures the safety and comfort of the flight.

Other levels of turbulence, such as light turbulence, indicate less significant changes and are typically easier to manage, while severe turbulence involves large and abrupt changes that can place the aircraft and its occupants at risk. Clear air turbulence occurs in cloudless conditions and may be difficult to predict but does not specifically refer to significant changes in altitude as a defining feature.
