What is the general classification for turbulence that is sudden and violent?

The classification of turbulence that is described as sudden and violent is known as extreme turbulence. This type of turbulence can pose significant risks to the aircraft and its occupants, resulting in drastic changes in altitude and attitude. Pilots experience extreme turbulence very rarely, but when it occurs, it can lead to momentary loss of control.

Extreme turbulence is characterized by conditions that are so intense that they can exceed the structural limits of the aircraft, potentially causing damage. This differentiates it from severe turbulence, which, while still dangerous, is not typically considered as catastrophic as extreme turbulence. Moderate and light turbulence are less intense and more manageable, allowing for better control of the aircraft.

Understanding these distinctions is crucial for both pilots and passengers, as it helps in assessing the potential hazards and taking appropriate safety measures during flight.
