What is the max operating airspeed (VMO) for the ERJ 170/175?

The maximum operating airspeed (VMO) for the ERJ 170/175 is indeed 320 KIAS. This limitation is critical for safe flight operations, as exceeding this airspeed could lead to structural failure or loss of control due to aerodynamic forces acting on the aircraft. The specified VMO value is determined through rigorous testing and is part of the aircraft's certification process, ensuring that the aircraft can operate within safe performance margins at various altitudes and configurations. Flight crews must always adhere to these limitations to maintain the safety and integrity of the aircraft during all phases of flight, from takeoff to landing. Understanding VMO is essential for pilots to prevent exceeding operational limits and to ensure compliance with safety regulations.
