Vmc Definition
The minimum airspeed at which directional control can be maintained with the critical engine inoperative.
Critical Engine Definition
The engine that, when fails, most adversely affects the performance and handling qualities of the airplane Seminoles do NOT have a critical engine).
What is “directional control” and how do you know when it’s lost?
Directional control has been lost when full rudder input is applied to the operative engine and plane begins to yaw into inoperative engine.
“I know that I have lost directional control when I have full rudder input into the operative engine and the plane begins to roll and yaw into the inoperative engine. I will correct by reducing power and angle of attack.”
