What is Vfo for flap setting 20?

Vfo, or the maximum flap extended speed, is crucial for safe operations when flying with flaps deployed. For a flap setting of 20 degrees on the CRJ 200, Vfo is established at 200 KIAS. This speed must not be exceeded to prevent potential structural damage or adverse handling characteristics that could arise from operating above the designated limits with the flaps extended.

The specifications for Vfo are based on the aircraft's design and performance characteristics. Knowing this speed is essential for pilots to maintain control and adhere to safety regulations during flight phases that require flap deployment, such as approach and landing.

This understanding of Vfo for the 20-degree flap setting is essential for proper flight planning and execution, underscoring the importance of adhering to these limitations in flight operations.
