You cannot shield potential pilots from this truth.
No you can't and I never said that we should. What I said is that our skills as pilots grow with time. Trying to cram it all into the basic PPL does not work. I find your comments about the rudiments a bit hard to understand. We teach a syllabus that has had little change in decades apart from changing spin recovery to spin avoidance. Are you saying that the whole PPL is now only rudimentary because of a change in one skill?
It is far better to take a progressive approach.
Fortunately it is a moot point as the regulators world wide reached the same conclusion years ago and their is no evidence to indicate the decision was wrong. There is no evidence to indicate that there are more spin accidents because avoidance rather than recovery is taught.
Anything beyond this is argument for arguments sake in typical PPRUNE style. As I have said a number of times to those who do want to argue, simply provide the evidence that spinning needs to be returned to the basic training and I will look at it. My mind is not closed to evidence, just to blind opinion with no supporting data.
