One issue you do not mention is rotor downwash strength. Compared to the S61 the 92 can have much higher disc loading (ie small disc diameter, high AUW). This becomes very relevant during SAR, for example pushing down/away a floating object, and most importantly the possibility of the crewman, stretcher entering a high-speed rotation when on the wire, which is at best debilitating and at worst, I am told, potentially fatal).

I have to admit I am not sure whether there are SAR S92s actually in service yet, but if there are has anyone had any experiences of the downwash problem?

And Nick, before you say it, of course the 225 is likely to have exactly the same issue!
