Interesting topic with interesting views.
Here's my grain of sand to the Mite Mound for what it's worth.
I fall somewhere in the middle..but then I would I am a wishy washy liberal.
Do I think it should be mandatory to climb to 5,000' and see and then replicate recovery from a conventional 2-3 turn spin....NO. Why because it's not what is going to kill us as has been eloquently pointed out already.
Do I think a student should be taken up to a safe height and SHOWN a spin develop from a botched low speed turn (as terrifingly descibed in "Stick and Rudder")....OH YES. Why...because that is what will kill us.
Why show why not descibe, brief, watch the youtube clips ? For the same reason the gentleman above could so well remember his first solo.....he was stressed and had adrenaline squirting out of his ears. In the correct quantities nothing sears information into long term memory as well. See it hear it feel it understand it; the early warning signs, the developed spin, the disorientation, the tremendous height loss (and therefore the extreme danger at low level) the strong natural urge to make control inputs that will actually worsen the situation;....HOW TO STOP IT AT IT'S INCIPIENT STAGE. Infact why restrict this to students why not make it a part of the biannual check.
If this requires (and it will) Flying Schools to have;
Aircraft certifiable for the above manoevures
Instructors capable and current to demonstrate
Parachutes
GOOD!!
Thanks for your time have a nice day,.....TIM
