CTD-
Just like a drivers lic. flying is a privileage and not a right. The events of 9/11 proved that.
As FAR as single engine and single pilot IFR are concerned, I don't beleave these are non-sense. Are there increased risk in these activities? Sure. But the only way to reduce these risks to zero is to not fly. Both these operations, when properly conducted are safe, mind you not without risk but still safe. I beleave the rewards out way the risks.
It's great to live in a place where we are allowed the freedom to make these decisions ourselves.
Daranfin-
The are no federal requirement preventing full down autos at any level. At our school, we do power recoveries until proficient then demo at least one full down auto before solo. Prior to your private check ride about 1 out of every 3 autos will be to the ground.
We do full down autos at all levels of training. A student will usually see them towards the end of the training program.
