I'm no expert, but these are all lessons I don't think will every leave me due to the fact they have been shouted at me so many times!!!!
teknow, good instructors shouldn't be shouting IMHO!
This thread proves what I often say about aviation - "Operating an aircraft safely is quite simple. It's just that there are a lot of people around trying to make it incredibly complicated".
The place and time to find out about lower speed characteristics of an aircraft is at a (safe) altitude.
Correct "normal" approach speeds are 30% above the stall speed!
There is a difference between the "signs of an approaching stall" and the "identification of a
full stall". One sign of an
approaching stall is the stall warner operating. Typically the stall warner operates at 5 to 10 kts above the stall speed.
As has been said previously there is a difference between the stall warner momentarily sounding or doing so continuously.
In a correctly flown circuit you shouldn't
have to exceed thirty degrees of bank and I wouldn't want low hour students doing so. If you find yourself in that position better to level the wings (or reduce bank angle) and Go Around. Once settled back at circuit height do some analysis to trouble shoot how you got in that position to avoid same on next approach.
