messiah,
A single serviceable AH and a VSI is all that is needed to tackle the problem. Remember many of these accidents have happened in adequately equipped aircraft on CAVOK nights without any commercial pressures.
if a single serviceable ah and a vsi is all that we need why have many of these accidents, as you contend, happened in
adequately equipped aircraft. surely that's a contradiction.
i'm remembering, as you asked, and to my knowledge, nvfr helicopter accidents have nearly all been in crap weather or pitch black no moon nights. all of these accidents involved ems machines with no commercial pressure. in fact i know of no other accidents, private or commercial, involving helicopters operating under the nvfr.
none of the pilots in any of these accidents were themselves adequately equipped for their flights.
i would be interested to know of the night cavok instances.
