VMCG vs VMCA - 747 400
Hey...just wondering is someone can shed some light:
One of the questions I have come upon:
What is higher on the 747 400: VMCG or VMCA and Why? anyone know the approx or actual numbers?
From what I have looked up it is VMCG...which if equal to V1 would make sense to me.... becuase on the one's I have flown the V1 speed at max gross is higher than the VMCA speed...
Why? I could not find this in any of my books...but I figured it had to do with the fact that the speed would be higher on the ground to offset the yawing moment becuase of the additional friction force required with the wheels on the ground...
????
