Heliport,
Why was this thread resurrected?
In Australia, this operation was one of the first that was regulated on a risk management basis. The only time it really made sense was when the mission was time critical - mustering, aeromed and firefighting being obvious candidates - rather than mere convenience.
The policy intent was crystal clear - it is a pity (perhaps more a disgrace) that the final drafting muddied the waters so much.
