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

The maximum speed for landing gear extension (Vlo) in the ERJ 170/175 is indeed 250 KIAS. This speed is significant as it indicates the maximum permissible airspeed at which the landing gear can be safely extended. Exceeding this speed can lead to structural stress or failure of the landing gear mechanism, complicating the deployment process and potentially resulting in an unsafe configuration during landing. It is crucial for pilots to adhere to Vlo to ensure proper operation of the landing gear system and maintain safety during descent and approach for landing. Proper knowledge of Vlo is a fundamental part of understanding the aircraft's limitations and operational performance, ensuring safe operations within the performance envelope.
