3D - I guess no-one at your end has thought what you will do if the winchman is incapacitated, either in the aircraft or on the ground/deck/in the sea and the co-pilot needs to start earning his money by either winchopping or winchmanning to save lives. Or, what if you have multiple casualties requiring CPR/restraint/TLC and the co is needed.
I didn't say there was a C of G problem, I asked if there was one - shoving 1000kgs of fuel way aft of the rotor mast usually causes problems in helicopters but I notice the cockpit is a long way forward of the mast - a couple of fat pilots should sort any load and balance problems
Leopold - there will be harmony when everyone is doing it our way
