I reckon 150hrs and an IR and the factory training course and one should be pretty safe
One could make the argument that instrument capability should be integral in the PPL
I can't understand spending $400k or so and scud running everywhere. It just doesn't add up.
Getting out of here very fast now........
Anyway, this is tantamount to requiring a proper Type Rating for anything capable, and we don't want more regulation! But it is true that the rating system was designed decades ago, and contains a load of silly stuff e.g. need a complex signoff for simple stuff like retractable gear (trivial) or a VP prop (a bit less trivial but still trivial). An SR22 is hugely far from trivial - unless the pilot pretends it is a C172 and sticks a huge post-it pad over the screens
