This came via my SNAM membership. I guess one of the most interesting points made in it is that the helicopter crew will eventually require your GPS coordinates, this piece accepts that transcribing these from an IGN map when under stress on the mountain is fairly difficult. It suggests that in the first instance you should describe your position via the “place names” and allow the operator to discover the correct coordinates. I wonder why it didn’t say “carry a GPS and relay the coordinates directly to the operator”?
