What is the maximum speed in turbulent air for the ERJ 170/175?

The maximum speed in turbulent air for the ERJ 170/175 is established to ensure safety and structural integrity during flight in adverse weather conditions. The correct maximum speed in turbulent air, which is 250 KIAS below 10,000 feet, is directly related to the aircraft's ability to handle increased stresses that can occur in turbulent conditions. This speed limit is set to prevent excess loads on the airframe, which could lead to potential structural issues.

In turbulent air, maintaining this speed helps the pilots manage the aircraft's response to sudden bumps or changes in airflow, enhancing passenger comfort and reducing the likelihood of encountering a loss of control or structural failure. The limit is crucial for operating the aircraft safely within its designed parameters, ensuring that it remains within a safe operating envelope to mitigate the risks associated with turbulence.
