What signals indicate you should abort a maneuver due to faults?

• A. A loud voice from the cockpit.
• B. Alarms or warnings and abnormal engine or electrical performance.
• C. A green signal light.
• D. A positive radio check.

Answer: (B)

In this situation, the signals to abort are alarms or warnings and any abnormal engine or electrical performance. Alarms and warning indicators are designed to alert you that something is out of safe operating parameters. If the engine shows abnormal readings—overheating, unusual RPM, loss of power, low oil pressure—or electrical indicators warn of faults in the electrical system or charging system, you should stop the maneuver and address the issue before proceeding. These conditions mean continuing could put the crew or vessel at risk, so aborting is the prudent action.

Think about the other options as not reflecting fault conditions: a loud voice from the cockpit could be a command, but it isn’t a fault signal; a green signal light usually means normal status; a positive radio check just confirms comms are good. None of these indicate a fault that would require aborting a maneuver.
