What is the maximum operating speed (Vfo) for Flaps 30?

The maximum operating speed (Vfo) for Flaps 30 is 185 knots indicated airspeed (KIAS). This speed is crucial as it denotes the maximum speed at which the flaps can be safely deployed without risking structural damage to the aircraft or loss of control.

Each flap setting has a corresponding maximum operating speed to ensure safe flight during various phases, such as approach and landing. Flaps are extended to increase lift at a lower speed, enabling a steeper angle of descent while maintaining control and stability. Exceeding the maximum speed for a specific flap configuration can lead to aerodynamic issues, such as excessive drag or potential flap failure. Therefore, knowing the Vfo for each flap setting is essential for pilots to operate the aircraft safely.

In this case, 185 KIAS is recognized as the definitive limit for Flaps 30, allowing pilots to ensure compliance with operational parameters and mitigate risks during flight operations.
