in fact you should be able translate with just less that 1/2" more than HIGE from the IGE hover.
TET, double the bet and do it without moving the collective at all.
SE, hover power is take-off power (you don't need to pull pitch to accelerate the aircraft); more is nice to have; less is a serious power limitation.
Power limitation training is great fun but the techniques used should be considered desperate measures and not a way to get around being overweight:-
If you can't manage HIGE, a cushion creep take-off is an option: but you are probably overweight for the conditions and a poorly managed approach may leave you red-faced.
If you haven't got the power to manage a cushion creep you
might be able to do a running take-off. But you are asking for it if you do, because you will be seriously power-limited on approach.
In this accident, the pilot probably had enough power to manage the entire flight safely; but appears not to have seen a great big trap staring him in the face.
n5296s you are wise to be wary of VRS; some people seem very vague and receive no training in it at all. Personally, I don't think this accident has jack to do with VRS though.
