In today's video, we are going to talk about the Vmcg, Minimum Control Ground Speed.
The Vmcg is the minimum speed at which, using only the Aerodynamic Surfaces, such as, the rudder, you will be able to maintain the directional control during takeoff should an engine failure occur.
The Minimum Control Ground Speed must be lower than the V1 decision Speed and it is only applicable for ground operations.
This is so because, if you experience an engine failure above the V1 you should continue the takeoff and if you are not at Vmcg or higher, at the moment of the engine failure, your rudder won't be able to contrast the yaw moment caused by the engine operative.
The lower the power setting you use for takeoff the easier will be to control the Aircraft laterally in case an engine failure occur.
That's why during narrow runway operations we use the minimum thrust required for a safe takeoff.
So as you can see the Vmcg is a crucial speed during the takeoff phase, and it all depends on how effective is the rudder when applying full deflection should an engine failure occur during the takeoff.
Always remember that if an engine fails before the V1 you should stop the takeoff.
