What is the air minimum control speed (Vmca) with propeller feathered and flaps up?

The air minimum control speed (Vmca) with the propeller feathered and flaps up is specifically designed for situations where one engine is inoperative, and the other engine is at full power. In the King Air 350, this critical airspeed is crucial for maintaining control of the aircraft when an engine fails during takeoff or in the climb-out phase.

At this speed, the aircraft can maintain controlled flight with one engine inoperative, ensuring that the pilot has enough control authority to counteract the yawing motion caused by the loss of power from the failed engine. In the King Air 350, this speed is set at 94 KIAS, reflecting the aircraft's aerodynamic properties and engine performance.

Each of the other choices represent speeds that do not correspond to the specific operational limitations of the King Air 350, as they are not designed for the expected minimum control speed under the outlined conditions. Understanding Vmca is essential for safe operations, especially during critical phases of flight where engine reliability is paramount.
