At what speed does the air minimum control speed (Vmca) occur with the propeller feathered and flaps in the approach position?

The air minimum control speed (Vmca) is a critical speed for multi-engine aircraft, including the King Air 350, indicating the minimum speed at which a pilot can maintain control of the aircraft with one engine inoperative. In this specific scenario, the Vmca is evaluated with the propeller feathered and flaps in the approach position, which is essential for understanding the aircraft’s performance in configurations used during landing or approach phases.

The speed of 93 KIAS represents the condition where the aircraft is at a low power setting, which is typically the case while configuring for landing. This aligns with standard operating procedures, where Vmca decreases with configurations that increase drag and reduce thrust such as a feathered propeller and the flaps in the approach setting. Such configurations are part of a safe operational envelope that pilots must be aware of to ensure proper control and handling of the aircraft in critical phases of flight.

Therefore, the correct identification of 93 KIAS as the Vmca under the specified conditions is crucial for pilots to ensure they stay above this speed during an engine-out scenario, ensuring safe handling and control of the aircraft. Understanding this figure is vital for flight planning and operational safety, demonstrating the importance of recognizing various performance parameters and their implications for
