What is the design maneuvering speed (VA) for the ERJ 170/175?

The design maneuvering speed (VA) for the ERJ 170/175 is correctly stated as 198 KIAS. This speed is a critical limitation in the flight envelope of the aircraft, where the pilot can expect the aircraft to be able to withstand full deflection of the controls without exceeding the structural limits of the airframe. At VA, any bank angle and control input will result in the aircraft experiencing loads within safe limits, which is particularly essential during turbulent conditions or when performing abrupt maneuvers.

Understanding this speeds the pilot can maintain maneuverability without risking control effectiveness or structural integrity. The selection of a specific VA is based on the weight of the aircraft and helps provide a safety margin during flight, particularly in scenarios such as stall prevention and recovery. It's important to be aware of these limitations for safe aircraft operation, ensuring that pilots operate within these parameters for optimal safety and performance.
