It involves a 180-degree turn followed by a 90-degree turn in the opposite direction, allowing the vehicle to quickly change direction and continue on its original path. This maneuver is commonly used in maritime navigation to avoid obstacles or hazards while minimizing the distance traveled.

    • Person missing in action

    • Immediate action

    • Delayed action

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    In any situation where a person is noticed to be overboard from the bridge, immediate action should be taken. This means that as soon as the person is noticed missing, appropriate measures should be taken to locate and rescue them. Delayed action would be ineffective and could result in serious harm or even death for the person overboard. Therefore, the correct answer is "all of the above" because in any situation, whether it is a person missing in action, immediate action should be taken to ensure their safety.
