ACS element text (the applicant demonstrates understanding of)

Inadvertent slow flight and flight with a stall warning, which could lead to loss of control.

Bottom line

Many loss of control in-flight (LOC-I) accidents are the result of stalls, spins, or accelerated maneuvers. The real danger is inadvertent stalls induced by distractions during routine flight situations, not the intentional practice of stalls and spins. During slow flight, any further increase in angle of attack, increase in load factor, or reduction in power will result in a stall warning, such as aircraft buffet or the stall horn.
