No training is correct its just most don't practise regularly. And thier currency is low.
The reactions don't get instinctive until its been repeated at regular intervals for a while. Which is why instructors click quicker. You can be doing stalling 3-4's a week same with the other exercises. And when you teach it makes you think about your actions which the renforces them.
If ppls would go once a month for an hour doing the exercises for the first year with or without an instructor it makes a huge difference to there reactions under stress.
How about a show of hands when was the last time you did a stall or pfl or steep turn?
I was last month in the sim for stalling and steep turns. Did them single engine in a twin to boot which makes matters a bit more interesting.
