Spin avoidance or recovery training
I was required to learn to perform full spin recovery when I learned to fly in 1960. In 2005, when I made a return to flying, after a break of many years, I was given the new 'spin avoidance' training.
So having now experienced both, my view is that everybody ought to experience a fully developed spin, even if only once and as a passenger, purely for purposes of demonstration.
After all, if you have never actually experienced a spin, how can you form any concept of what it is you are avoiding when you have spin avoidance training?
Unless you have actually seen with your own eyes that YOUR aeroplane really will spin, and seen the potentially terrifying sight of the good earth up in front of your windscreen and spinning like a top, the spin will always remain merely a theoretical possibility.
Without this, I feel that as time passes people will gradually become inclined to tempt fate, taking the attitude 'well it just doesn't happen; and it can't really be all that bad can it'?
