Here's an idea: Let's get CASA to legislate so that the prescribed penalty for flying VFR into IMC is death.
Would that change anything? No.
Guess what, outnabout: There's already plenty of laws prohibiting and imposing liability for flying into IMC while operating VFR!
The knee jerk "more regulation" solution only works in the heads of people who think that the most efficient way to change behaviour is to make another law. So typically Australian...
The hundreds of millions that have been wasted on the regulatory reform program would have paid for IFR ratings and renewals for every Australian pilot, plus education, education, education and more education on human factors in aviation.
And if these people had died on the road on the way to or from the aerodrome, there would have been nary a peep on PPRuNe.
