Maneuvering with one engine inoperative.

ACS element text (the applicant demonstrates understanding of)

Maneuvering with one engine inoperative.

Bottom line

An airspeed is soon reached where full right rudder travel and up to a 5° right bank can no longer counteract the asymmetrical thrust, and the airplane will begin to yaw uncontrollably to the left. No engine failure should ever be introduced below safe, intentional one-engine inoperative speed (VSSE).
