I don't know the Qld/NSW criteria, but AAV (Air Ambulance Victoria) have the 412EP operating to full accountability to rooftop pads.
Do the CAA in UK require this? I'd be surprised if many of their machines could achieve it, especially if (as is inferred here) they have to operate IFR at night with all the additional fuel that would require
London HEMS are (
AFAIK) the only UK HEMS regularly operating to a city roof top helipad. They achieve PC1 weight mainly due to the fact that their radius of operations is within the Greater London Area with a low fuel load. I'd be interested to know how far AAV can fly at PC1 helipad weights.
