mutt and jt-
I have charts for my DC-8 for both "dry" and "slippery and icy" Vmcg. The "dry" Vmcg is approx. 30 KIAS less than the "wet and slippery" values.
These lower numbers are not published for the use of line crews, but I find them valuable for test flights and 3 engine ferries. I've tested them in the simulator, and they do work. The reason, of course, is that in real life, the rudder pedal steering IS connected, and there IS friction working on the nose wheels.
You guys are the engineers, not me. Are there other a/c types that have those charts available? I would imagine there are.
On the subject of which engine is critical in a crosswind takeoff, the trick is to predict WHICH engine is going to fail!
