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).

Zero thrust means the pilot sets power on one engine such that drag from its rotating propeller equals that of a stopped feathered propeller.
