ACS element text (the applicant demonstrates understanding of)

Low altitude maneuvering, including stall, spin, or controlled flight into terrain (CFIT).

Bottom line

Many LOC-I accidents are the result of stalls, spins, or accelerated maneuvers. An airspeed is soon reached in which full right rudder travel and a 5-degree bank can no longer counteract the asymmetrical thrust, and the airplane will begin to yaw uncontrollably to the left. Multiengine instructors should approach simulated engine failures below 400 feet AGL with extreme caution, and failures below 200 feet AGL should be reserved for simulators and training devices.
