ACS element text (the applicant demonstrates understanding of)

Factors and situations that could lead to an inadvertent power-off stall, spin, and loss of control.

Bottom line

The real danger is not intentional stall practice but inadvertent stalls induced by distractions during routine flight situations. It is possible to stall the wing at any airspeed, at any flight attitude, and at any power setting. When the airplane reaches the stall warning, recovery is accomplished by first reducing the AOA until the stall warning is eliminated.
