The Flight Level (FL) or altitude range where the air is disturbed.
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: turbulence
This report outlines the essential components, classifications, and standard procedures for reporting aviation turbulence based on FAA and international aviation standards. The Flight Level (FL) or altitude range where
Aircraft is tossed violently; practically impossible to control. Potential for structural damage to the airframe. Reports must also specify how often the bumps occur: Occasional: Less than 1/3 of the time. Intermittent: 1/3 to 2/3 of the time. Continuous: More than 2/3 of the time. 4. Common Types of Turbulence Potential for structural damage to the airframe
Crucial because "severe" turbulence for a small Cessna might only be "light" for a large Airbus A380 .
