What does the critical engine-out minimum control speed (Vmc) signify?

• A. The minimum speed needed to take off safely
• B. The minimum airspeed to maintain controlled flight with one engine inoperative
• C. The optimal cruising speed for fuel efficiency
• D. The speed required for landing in adverse conditions

Answer: (B)

The critical engine-out minimum control speed (Vmc) represents the minimum airspeed at which an airplane can maintain controlled flight with one engine inoperative. This speed is crucial because if the aircraft slows below Vmc while in a multiengine configuration and one engine fails, it can lose control and lead to an uncommanded yaw towards the inoperative engine, which can ultimately lead to a dangerous situation. Understanding Vmc is vital for pilots operating multiengine aircraft, as it informs them of the necessary airspeed to maintain control during crucial phases of flight, especially during takeoff and go-around maneuvers. It is important for pilots to be aware of Vmc to ensure safety and effective handling of the aircraft in case of engine failure.
