Dual pilot? You must be military and unable to do your job without someone holding your hand along the way.
Ive seen more issues with two pilots than one. Flying a helicopter single pilot IFR is not new, it’s not hard. You can’t teach people good decision making, sadly. Stupid people will crash aircraft no matter how capable it is.
BUT I do believe there is no substitute for actual helicopter IFR experience. Everyone is afraid to commit to IMC. For no good reason other than the fact that they haven’t done it.
