There is little direction from the manufacturers which leaves when to pull the chute in the hands of often inexperienced pilots. That is a dangerous way to proceed and there should be far more expert and approved guidance!
Pace we are not that far apart, saying it is a dangerous way to proceed leaving it up to inexperienced pilots and there should be more approved guidance, I personally do not agree.
In a decade what has been dangerous about leaving it to inexperienced (or experienced) pilots?
The main danger is they do not pull the damn thing and crash and burn.
There have been some accidents and chute pulls where you do question if the guy at the controls is a competent well trained pilot or some incompetent half baked idiot flying the aircraft.
I do not think any more accidents than any other aircraft type and probably less due to half baked idiots (but certainly a few)
