I guess you need to look at the probability of flying into something when grovelling vfr as against the probability of the engine failing....which in a modern turbine is virtually never !!! How many accidents have there been in this country during an ifr flight ? I think you will find that there have been very very few . Maybe more training and a cheaper way of retro fitting autopilot onto,at least turbine helicopters,and more development of gps with terrain etc could make a change for the better. I know that i would feel happier at msa in cloud if it were legal. After all , i think we all know quite a few very high hour pilots who do regularly choose, rightly or wrongly, to go this route rather than trust their old eyesight!!
