What is the maximum flaps extended speed (Vfe) at 45 degrees for the CRJ 200?

The maximum flaps extended speed (Vfe) at 45 degrees for the CRJ 200 is indeed 145 KIAS. This is significant because it indicates the highest speed at which the aircraft can safely operate with the flaps fully deployed in order to maintain control and prevent structural damage.

In operations, understanding Vfe is crucial for pilots, especially during approach and landing phases when the flaps are extended to enhance lift and control at slower speeds. Exceeding this speed while flaps are set to 45 degrees could lead to adverse aerodynamic effects and potential damage to the flap system.

When preparing for landing or when configuring the aircraft for descent, pilots must ensure they adhere to this limitation to maintain adherence to safety protocols and ensure a smooth and controlled approach to landing.
