What audible signal indicates the Engine RPM Overspeed device has tripped?

• A. A beeping chime
• B. The engine RPM gauge shows a red flag
• C. No signal is given
• D. An alarm sounds

Answer: (D)

When RPM exceeds safe limits, the system must grab attention immediately, so an audible alert is used. The Engine RPM Overspeed device trips to protect the engine, and the quickest way to warn the crew is an alarm sounding. A visual cue like a red flag on the RPM gauge can accompany it, but the question focuses on audible notification, and a dedicated alarm is the standard signal for this condition. A scenario with no signal would fail the safety purpose, and while some setups may include a chime, the explicit audible alarm is the clear, expected indicator.
