If a required artificial horizon and "night rating" didn't keep a 16,000 hour pilot from crashing, then what good would it do a low time guy in an R44?
It matters not what instruments the aircraft is fitted with, all can still come unraveled, two Boeing 747 have taken off at night and promptly rolled inverted and crashed, all because the pilots attitude indicator had failed, the fact there was another pilot and another two working attitude indicators didn't save them. In the early days of single seat fighters the loss rate due to the leans was high, because to tune radios/nav aids the pilot had to look down and some what aft as they were located on a console beside the seat.
Instead of increased regulation it might be better to just try harder to get the point across that if you're not going to be able to clearly see the ground at anytime during a night flight, then just file and fly IFR
That may be good advice in the US given their system, but impracticable in Oz, my opinion is Oz, even with the deficiencys pointed out in the report, has a pretty good system.
