Interesting thread with robust discussion.
Just one thought on how to change culture, in Australia most health services only allow helicopters to land at a hospital pad that can maintain Cat A performance. This would then extend to only twins being allowed in and the natural extension is that they are also IFR aircraft. Would a change in health service culture lead towards a change in aviation culture?
I realise the risk of comparing apples with oranges as has been hinted at with comparing US and UK models.
