Glider Pilots are still taught spinning but the we spend a lot of time in rough air, circling, at high angles of bank and low speed. Asking for trouble isn`t it?
Most training gliders are not that easy to spin, they tend to require a bootful of rudder input just at the point of stall and this is not the way anyone is going to get into an inadvertent spin. Try to get your aircraft to spin by circling whilst going slower and slower until something happens. Unless your aircraft has some very unpleasant characteristics, it is surprisingly difficult to make it spin.
I have heard that the `usual` way to get your aircraft to spin in on the approach is to cross the controls trying to see if there are other aircraft trying for your bit of air hidden under your outside wing. Haven`t got around to trying that one at height yet.
Not showing a student what a spin looks like from the inside at the very least is sheer stupidity. If spin training is not included in the PPL syllabus then the first spin the student sees will probably kill him unless he is high enough for the aircraft to sort itself out as most will do if left alone but will he leave it alone? Spins Must be taught.
