Experiencing Air Turbulence: Classifying and Reporting Different Types

In the world of aviation, turbulence is a common phenomenon that can affect flights. To ensure safety for all aircraft, it's essential for pilots to effectively communicate turbulence conditions to Air Traffic Control (ATC). Here's a guide on how to report turbulence, based on the types and intensities commonly experienced.

Identifying Turbulence Type and Intensity

Turbulence is categorized into several types:

Light Chop/Chop: Slight, rapid, rhythmic bumps with minimal effect on aircraft attitude.
Light Turbulence: Momentary erratic changes in altitude or attitude, causing a slight strain against seat belts.
Moderate Chop/Choppy: Consistent bumps but little change in altitude or attitude.
Moderate Turbulence: Changes in altitude or attitude with definite strain against seat belts.
Severe Turbulence (not defined in the provided context): Large, abrupt changes in altitude or attitude, potentially leading to temporary loss of control.
Extreme Turbulence: Violent tossing, making control nearly impossible.

Including Turbulence Frequency

When reporting turbulence, it's crucial to include its frequency. Turbulence can occur occasionally, frequently, or continuously.

Providing Location and Altitude

Report the location and altitude at which the turbulence is experienced. This information helps other pilots and ATC to understand the scope of the turbulence.

Using Standard Reporting Format

Use phrases like "Light turbulence, occasional" or "Moderate turbulence, frequent" to clearly convey the information to ATC.

Example Report

"Center, aircraft XYZ reporting moderate turbulence, frequent, at 30,000 feet, approximately 20 miles northwest of waypoint Alpha."

By following this procedure, pilots can effectively communicate turbulence conditions to ATC, enhancing safety for all aircraft in the vicinity.

Additional Information

Light turbulence involves momentary, erratic changes in altitude or attitude, causing a slight strain against seat belts or shoulder straps, and potentially dislodging unsecured objects.
In light, moderate, or severe turbulence, walking in the cabin may be difficult.
Continuous turbulence occurs more than 2/3 of the time.

In light, moderate, or severe turbulence, unsecured objects in the cabin become dislodged.
Intermittent turbulence occurs 1/3 to 2/3 of the time.
When reporting turbulence to ATC, it's important to include the turbulence frequency.
In extreme turbulence, the aircraft may be temporarily out of control.

In the aviation industry, pilots are required to communicate turbulence conditions to Air Traffic Control (ATC) for the safety of all aircraft.
Turbulence can be light chop, light, moderate chop, moderate, severe, extreme, or not defined, each with varying effects on aircraft.
When pilot encounters turbulence, it's crucial to include the turbulence type, its frequency, and location/altitude while reporting to ATC.
To clearly convey turbulence information, phrases like "Light turbulence, occasional" or "Moderate turbulence, frequent" can be used.
The Boldmethod's Instrument Procedures course is designed to help pilots earn their instrument rating and master IFR, enhancing their skills in turbulence management.
Unsecured objects in the aircraft cabin can be dislodged during light, moderate, or severe turbulence, making walking in the cabin difficult.
Continuous turbulence occurs more than 2/3 of the time, while intermittent turbulence occurs 1/3 to 2/3 of the time, according to additional information provided.
