What does Vmc stand for?

Vmc stands for Minimum Control Speed. This is a critical airspeed for multi-engine aircraft, as it indicates the minimum speed at which the aircraft can maintain controlled flight with one engine inoperative. Below this speed, the aircraft may experience uncontrollable yaw and roll towards the inoperative engine, making it challenging to maintain directional control.

Understanding Vmc is essential for pilot safety, particularly during takeoffs and initial climb phases when engine failure is a potential risk. It ensures that pilots remain above this airspeed to maintain effective control of the aircraft. This concept is vital in multi-engine training since the dynamic behavior of an aircraft with an inoperative engine significantly differs from single-engine operations.
