This is why I love the 3 valleys. The ridiculously cheap off piste insurance which can be purchased with the ski pass allows an unbelievable area to explore... and get helicoptered out of if you're in trouble!
If you are dead the helicopter is not that useful.
And if you get trapped somewhere or injured without the appropriate equipment and safety knowledge you can still be liable for the costs of your rescue. It isn't a get out of jail free card.
If you are making safety decisions with respect to the possibility of a helicopter rescue then you should be sticking to the slopes until you get some more professional training.
