How long can the average VFR rated helicopter pilot keep an unstabilised helicopter upright in IMC without SAS or an autopilot? We are not talking about preplanned IMC but sudden loss of visual references. And to then set up and follow a PRA (frequency and altimeter changes, changes of heading / height / speed, set up ROD ) because most likely the cloudbase will be below minima elsewhere......... The only lesson to be learned is dont go IIMC. Put it on the ground, swallow your pride and have a cup of tea.
