Stall/spin training focuses on catching the horse after it's escaped, whereas I want to keep the gate closed.
Very good..analogy?..metaphor?..uh,..example?..
anyway, use that as a base from which to depart from the routine...
Stall/spin training is NOT just about preventing the stall. If that were all that it was about, I truly believe that most relatively average intelligent persons could and would keep the nose down below stall angle for an entire flight...except for the dang landing.
If we had a huge undercarrage like our car with big wheels and tires and axles and brakes, we could come cruising in to land at cruise speeds and drive that baby onto the highway and slow it down like a car.
But we can't. For weight purposes, we have little skinny landing gear and tires and tiny brakes and we have to slow it down in the air and stall it onto the runway.
This is the Primary Purpose of Stall Training. It is landing Training. The student should be able to flare, hold a landing attitude throughout a stall and power up from the stall into a go-around with no change in heading and no loss of bank control and control of pitch and power in the same precise way that should be demonstrated in the fullstall landing and goaround. That is the purpose of stall training. Along the way, stall prevention is the natural by-product, not the end goal.
With this objective in mind, if we look at your horse out of the gate metaphor and compare it to real life, the reality is that we try to keep the gate closed and we train to that objective, but we recognize that, in an imperfect world, the gate is going to be knocked open a time or two in our life-time of gate-keeping. The wind will knock it open, or the latch will rust out, or...whtever, you can (or should) be prepared for that eventuality, and have some hands-on practice at getting the gate shut again before the horse gets out, and if he does, how to get him back in.
The military teaches spins before solo. They recognize the importance of this ability.
You seem to disregard any information as important unless it is in a certified statistical scientific emperical evidence form. There ain't none.
Like there ain't no statistical evidence to show how much training it takes an individual to learn to ...solo...or play a piano...or ride a bycycle...
These are individual skills...flying is an individual skill, and some people shouldn't be flying an airplane like some people shouldn't ever put a horn to their lips.
Any instructor that has been training students through the years and has been in the mix of non-spin trained and spin trained will attest to the overall proficiency of the properly trained stall/spin pilot over the non-trained stall/spin pilot.
The proof is there; it just is not in a form of your acceptance.
