If all else fails:
True, training and temperament cannot replace having sight on a dark night.That is where the investment in technology comes in.All three need equal attention by the Operators.I believe NVGs are a no-brainer as far as a quantum leap in technology is concerned.They are inexpensive and they work!
If the Operators want legislation by the FAA on this before they are forced to invest dollars then that is what they will eventually get.Meanwhile, the we-have-been-doing-this-for-so-many-years-safely-without-any-stinking____(put your device in here i.e. TAWS,GPS,NVG RADALT.etc) -we-don't-need-it mindset of the managers and (forgive me) the older generation of pilots has to change.
That change is hard to predict.It will have to be evolutionary rather than revolutionary.
