At what maximum speed can the CRJ 900 and CRJ 700 fly with flaps set to 8 degrees?

The correct maximum speed for the CRJ 900 and CRJ 700 when flaps are set to 8 degrees is 220 KIAS. This limitation is established to ensure safe aerodynamics while the aircraft is within the flap operating range. Operating the aircraft above this speed with flaps extended can lead to increased aerodynamic stress on the aircraft and compromise control effectiveness. Each flap setting has associated maximum speed limitations that are determined during the aircraft's certification process, taking into consideration factors such as lift, drag, and overall stability. Thus, adhering to the specified maximum speed with flaps at 8 degrees is crucial for safe operation.
