ACS element text (the applicant demonstrates understanding of)

Set the engine controls, reduce drag, identify and verify the inoperative engine, and simulate feathering of the propeller on the inoperative engine (evaluator should then establish zero thrust on the inoperative engine).

Bottom line

The failed engine is the side that requires no rudder pressure. Having identified the failed engine, the procedure is to feather that engine and adjust power to maintain descent angle to a landing. When zero thrust is set to simulate a feathered propeller, the cowl flap is normally closed and the mixture leaned.
