What is the Mmo (Maximum Mach Operating Speed) for the ERJ 170/175?

The Maximum Mach Operating Speed (Mmo) for the ERJ 170/175 is 0.82. This limitation is crucial for flight operations as it defines the maximum speed at which the aircraft can safely be flown while maintaining structural integrity and performance within its design specifications. Operating above this speed can lead to adverse aerodynamic effects and may compromise the safety and control of the aircraft. Therefore, it is important for pilots and operators to be well-versed in this limitation to ensure compliance during various phases of flight, especially during high-altitude cruise conditions. Understanding the Mmo helps to prevent the risk of exceeding the aircraft's design limits and contributes to overall flight safety.
