What is the minimum control speed during takeoff for the CRJ 900?

The minimum control speed during takeoff for the CRJ 900 is 109 knots. This speed is critical for ensuring that the aircraft can maintain controlled flight in the event of an engine failure during the takeoff phase. It is specifically calculated to provide adequate control authority and ensures the pilot can effectively counteract any yawing moments that occur from thrust asymmetry. Operating below this speed when in the takeoff phase could lead to loss of control, highlighting the importance of understanding and adhering to the specified limitations in the Aircraft Flight Manual (AFM).

Knowing this information is essential for flight safety, particularly during the critical phases of takeoff and initial climb when engine failures are most likely to occur. Thus, the correct speed ensures that the aircraft responds appropriately to control inputs during this phase of flight.
