Shame the one thing that would have prevented the accident - adequate training in vertical departure profiles on instruments - isn't a recommendation because everyone gets caught up in the Vmini definition.
It is a helicopter and they are capable of safe vertical procedures (as anyone in the military will know) with sole reference to instruments - it is about time the CAA and EASA recognised that and ,mandated it as part of the training and IR.
The military even did it (and some still do) in an unstabilised single, quite safely so in a fully specc'd IFR twin it would be easy peasy.
