What is the maximum speed for landing gear extension in the ERJ 170/175?

The maximum speed for landing gear extension in the ERJ 170/175 is 190 KIAS. This limitation is set to ensure the safe operation of the aircraft's landing gear system. Extending the landing gear at speeds higher than the specified maximum can result in structural stress or failure of the gear mechanism, as the aerodynamic forces acting on the gear could exceed the design limits. The landing gear is crucial for the aircraft's safe landing and takeoff, and adhering to the maximum extension speeds is vital for maintaining the aircraft's integrity and safety during these operations.
