The only thing they have in common is some of the spelling
Er... there's a lot more than that in common.
If I get airborne at VMCG with wings level, - I only have rudder balancing assymetric thrust with the aircraft maintaining track parallel to the runway.
Once airborne at VMCA, I can use up to 5 degs bank into the live engine(s) using both rudder and sideslip to maintain heading.
Why do you think they permit us to use up to 5 degs bank? Do you think it makes VMCA worse?
