Potential engine failure after in flight or during an approach.

ACS element text (the applicant demonstrates understanding of)

Potential engine failure after in flight or during an approach.

Bottom line

Loss of directional control may be experienced at speeds almost 20 knots above published Vmc when the wings are held level. When training in an airplane, initiation of a simulated engine inoperative emergency at low altitude normally occurs at a minimum of 400 feet AGL to mitigate the risk involved and only after the learner has successfully mastered engine inoperative procedures at higher altitudes.
