I am seeking discussion and information here so please do not take what i have put below as a criticism.
My point is that a lot of what makes up this exercise is covered elswhere (on my syllabus) and was before this exercise was introduced.
i am also not sure that stalling as an exercise should be completed in full before the circuit and needs to be revisited before first solo.
I have put my comments in bold
Isn't some (or all ) of this exercise about being on the wrong side of the drag curve and you can't trade speed for height below Vmd. ie if you are slow and you need stretch the glide you aren't going to do it by raising the nose (as you would if you were above vmd.)
Covered in EFATO/ PFL
Demonstrating that full power at 45 kts will not produce a climb and how to get the ac back into climbing flight whilst losing min height before you need to do a full stall recovery.
A part of stall recognition/ recovery training
Appreciating what the ac looks and feels like at this speed (nose high, sloppy controls not as noisy, lots of power required to keep S+L) and how to safely get back to normal flight and all of the comments above about control are useful in getting people to recognise this condition.
A part of stall recognition/recovery training
Appreciating the importance of reaching the rotation speed on takeoff before you lift off. Pulling the stick back before this point (if the trees are getting scarily close) is more likley to increase drag and lower climb performance. Contradictorily in this case its better to lower the nose to gain height rather than raise it.
A part of circuit training and possibly better understood after circuit training commences
Also you get a higher rate of descent below Vmd than at Vmd.
A part of PFL training
