TRUE/FALSE: Once an engine is shut down by the DECU via the BIM, overspeed protection is automatically inhibited on the second engine.

TRUE/FALSE: Once an engine is shut down by the DECU via the BIM, overspeed protection is automatically inhibited on the second engine.

• A. TRUE
• B. FALSE
• C. NOT SURE
• D. NOT APPLICABLE

Answer: (A)

When the DECU shuts down one engine via the BIM on a twin-engine MH-65E, the overspeed protection on the surviving engine is automatically inhibited. This is intentional to prevent protective actions on the second engine from reacting to the sudden change in power/loads during an engine-out condition, which helps the pilot maintain control and manage the remaining engine without nuisance trips. In this design, the system prioritizes controllability during an engine-out scenario, so the statement is true.
