Simulate securing the inoperative engine.

Bottom line

When an instructor simulates an engine failure, the learner should respond with the appropriate memory items and retard the appropriate propeller control toward the FEATHER position. If workload permits, then accomplish the “Securing Failed Engine” checklist items to turn off systems and accessories no longer required. Following a simulated engine failure, the instructor cares for the "failed" engine just as the learner cares for the operative engine.
