What is the maximum speed with flaps set to 30 degrees for the CRJ 900?

The maximum speed with the flaps set to 30 degrees on the CRJ 900 is 175 KIAS. This limitation is critical for ensuring safe flight operations during configurations for landing. Exceeding this speed with flaps extended to 30 degrees can lead to structural issues or damage to the aircraft, as the control surfaces may not operate effectively at higher speeds.

Understanding this limitation is essential for pilots to maintain aircraft control and ensure a safe approach to landing. The other speed options exceed the established limit and could potentially compromise the aircraft's safety during operations requiring full flap extension. Knowing and adhering to these limitations helps to prevent accidents and ensures compliance with safety protocols.
