Regarding spinning, I was doing my PPL training around eight years ago. Neither I or other students went out and practised solo stalls - usually they would say that they have but all they did was some local crusing. I think that we were all fearful of it going wrong and not havng the instructor there for us.
When I did my tiger moth and subsquent chipmunk rating, I underwent extensive spin training before I was even sent solo. Now I even enjoy spinning, but the big thing is that a stall (and its variants) do not concern me. I have found that people who are jittery about stalling, once they get some spinning out the way, they are more confident about stalling and deal with them a lot better
The tiger is easy to recover and usually results in a height loss of less than 500ft (I recall 300ft being the norm), whereas the chipmunk you had to really get it time to recover.
With the requirement for slow flight now being in the BFR, will we see more stall related incidents?
