What is the turbulent air penetration speed at or above 10,000 MSL in the ERJ 170/175?

The turbulent air penetration speed for the ERJ 170/175 is specified as 270 KIAS/.76M when at or above 10,000 feet Mean Sea Level (MSL). This speed is designed to provide a balance between safety and performance during turbulence encounters. At this speed, the aircraft can minimize structural stress by reducing the effects of turbulence without overly sacrificing altitude loss or excessive airspeed.

When flying in turbulent conditions, it's crucial to adhere to the recommended turbulent air penetration speed because it helps ensure the aircraft is operated within design limits, ensuring structural integrity and passenger safety. The stated speed is optimized for handling unexpected air movements while maintaining control and flight stability.

The choice of 270 KIAS/.76M suits the aircraft's aerodynamic characteristics, providing a safety margin that helps pilots manage and navigate through turbulent areas effectively. This knowledge is vital for pilots operating the ERJ 170/175 to enhance safety and performance during their flights.
