What are the different warning times for turbulence?

The distinction between the warning times for turbulence is categorized as expected, impending, imminent, or occurring. This classification helps in understanding the urgency and timing of turbulence conditions that an aircraft might encounter.

• Expected turbulence is when conditions are known to favor turbulence, but it is not yet observed.

• Impending turbulence indicates that conditions are developing and turbulence is likely to occur soon.

• Imminent turbulence is when the conditions indicate that turbulence will happen very shortly, requiring immediate attention.

• Occurring turbulence refers to situations where turbulence is currently happening and requires immediate action from pilots.

This classification system provides pilots with a clear framework for assessing and responding to turbulence, which is critical for ensuring safety and comfort during flight. Understanding these terms allows pilots to communicate more effectively about turbulence conditions, assess risks, and take appropriate measures to manage and respond to turbulence situations.
