So why is there such a huge emphasis on 'stall speeds' in training?
Also, why in the current aircraft I'm training on (C172) if i pull nose up to say 20 degrees pitch at 100 kts on idle power, I don't stall (at least not for a short while). However, if I pull nose up at 50 kts with full flaps, stall will be imminent, without even being able to reach 20 degrees pitch up.
I am not disagreeing with what you say, just interested in the answer. In ground school we learned about the critical angle and that a stall can happen at any speed etc etc, but then we learn about Vs, Vs1 etc and see our susceptibility to stall is determined according to these speeds, even with 0 degrees pitch you'll stall at not much beneath them.
