ACS element text (the applicant demonstrates understanding of)

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

Bottom line

Sixty percent of stall/spin accidents occurred during takeoff and landing, and twenty percent were preceded by engine failure. Preoccupation inside or outside the flight deck while changing aircraft configuration or trim, maneuvering to avoid other traffic, or clearing hazardous obstacles during takeoff and climb could create a potential stall/spin situation.
