The Flight Level (FL) or altitude range where the air is disturbed.

This report outlines the essential components, classifications, and standard procedures for reporting aviation turbulence based on FAA and international aviation standards. turbulence

A standard pilot report ( PIREP ) for turbulence must include several critical data points to ensure air traffic control (ATC) and other aircraft have a clear picture of the conditions: The Flight Level (FL) or altitude range where

Turbulence is officially categorized into four intensity levels based on its effect on the aircraft and occupants: Aircraft Reaction Occupant/Cabin Effect Slight, erratic changes in altitude or attitude. Slight strain against seat belts; liquids may splash. Moderate More intense changes; aircraft remains in positive control. Definite strain against belts; unsecured objects dislodge. Severe Large, abrupt changes; momentary loss of control. Slight strain against seat belts; liquids may splash

Occupants forced violently against belts; walking is impossible.
