With Australia persisting with third world's best practise its not just turboprop RPT that have to put up with black hole approaches. Taking an A320 into ballina when its raining and at night is, in my view, unacceptable for any RPT. Even coming off the GPS approach some manouvring is required and thats when the "black hole" effect can get you. It has caught out aircraft in the past and has the real potential to do it again.
