What is the maximum operating speed for flight with the autopilot engaged?

The maximum operating speed for flight with the autopilot engaged in the CRJ 900 is 275 knots. This limit is crucial as exceeding it can result in control issues and potential structural damage. Autopilot systems are designed to operate within specific aerodynamic parameters, and maintaining the speed below this threshold ensures the autopilot can effectively manage the aircraft's performance.

This speed limitation reflects the aircraft's design and operational characteristics, considering factors such as stability and control response when the autopilot is engaged. Staying within these limits is essential for safe aircraft operation, particularly in various flight phases such as climb, cruise, and descent. Therefore, knowing the maximum speed at which the autopilot can operate safely is vital for pilots to ensure compliance with safety standards and to maintain control of the aircraft.
