Interesting thread.. I am neither agreeing nor disagreeing with the contributors....
The existing system promotes an unnecessary poor standard of piloting IMHO.
The above quote however is surely what this is ultimately about... ie Is there any statistical evidence that this is the case?
Check the Regulatory Review of General Aviation (CAA website - sorry I don`t have the full url to hand but it's reg review.pdf on my PC ) .... and imagine you're the decision maker with these data to hand.
From the doc...
There was no statistical evidence, based on fatal accident rates, to suggest that a fundamental change in the UK GA regulatory model was required.
You can draw your own conclusions, but for GA I`d much prefer the principle of 'If it aint broke don't fix it.'
