What is the purpose of turbulence penetration speed?

The purpose of turbulence penetration speed is to ensure safety and comfort during encounters with turbulence. This speed is specifically designed to provide optimal handling characteristics and structural integrity for the aircraft when flying through turbulent air. By flying at this designated speed, pilots can better manage the aircraft's response to sudden changes in airflow, reducing stress on the aircraft's structure and improving passenger comfort during bumpy conditions.

Maintaining turbulence penetration speed is crucial because it helps prevent excessive vertical oscillations, which can lead to discomfort for passengers and potential risk for the aircraft. This speed is lower than cruising speed, as it allows the aircraft to absorb and respond to turbulent air without compromising its stability or safety. Thus, the correct focus is on ensuring a calm flight experience and mitigating risks during turbulent conditions.
