In the context of multi-engine aircraft, what does the term "Vmc" refer to?

The term "Vmc" refers to Minimum Control Speed, which is critical in multi-engine aircraft operations. This speed indicates the minimum airspeed at which the aircraft can maintain controlled flight with one engine inoperative. Below this speed, the pilot may not be able to counteract the yawing motion experienced when losing thrust from one engine.

Understanding Vmc is essential for safety during flight maneuvers, especially during takeoff and climb when engine-out scenarios could occur. At speeds below Vmc, the aircraft might experience uncontrollable yaw towards the inoperative engine, which could lead to losing control. Therefore, pilots must ensure they are above this speed, particularly when analyzing performance data and executing procedures that involve engine failures.

The other options refer to different aspects of flight performance or aircraft handling characteristics, which are not specific to the context of multi-engine aircraft's response to an engine failure.
