Nope VMCA2 OR VMCG2 is not mentioned apart from in the 3 Eng ferry section.
The takeoff perf charts have no mention of these at all.
The computer data we use has the VMCG for 1 eng only on it.
Eg: Boeing 744, DXB RWY 12R
290 tonnes
To 58 EPR 1.54
Flap 20 VMCG 123
V1 134
VR 145
V2 155
That's all we need I guess.
