What do you think why generally ship could not establish a direct contact with an aircraft
- A.
  
  Because it is a procedure
- B.
  
  Because of the speed travel
- C.
  
  Because different frequency being used
- D.
  
  Because aircraft is for aircraft station only
Correct Answer
C. Because different frequency being used

Explanation
Ships and aircraft use different frequencies for communication, which is why they generally cannot establish direct contact with each other. Ships typically use very high frequency (VHF) radios, while aircraft use very high frequency omnidirectional range (VOR) or instrument landing system (ILS) frequencies. These different frequencies are specifically assigned for each type of vehicle, ensuring efficient and clear communication within their respective domains.

It is abnormal lowering of internal body temperature from exposure to cold air, wind or water
- A.
  
  Inundation
- B.
  
  Hypoglacemia
- C.
  
  Methaphorism
- D.
  
  Hypothermia
Correct Answer
D. Hypothermia

Explanation
Hypothermia is the correct answer because it is the abnormal lowering of internal body temperature from exposure to cold air, wind, or water. This condition occurs when the body loses heat faster than it can produce it, leading to symptoms such as shivering, confusion, slowed heart rate, and eventually, unconsciousness. Hypothermia can be life-threatening if not treated promptly.

What standard method of recovery that saves time and covers less distance
- A.
  
  Anderson turn
- B.
  
  270 maneuver
- C.
  
  Scharnow turn
- D.
  
  Williamson turn
Correct Answer
C. Scharnow turn

Explanation
The correct answer is the scharnow turn. The scharnow turn is a standard method of recovery that saves time and covers less distance compared to other methods such as the anderson turn and the 270 maneuver. 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.

- A.
  
  Person missing in action
- B.
  
  Immediate action
- C.
  
  Delayed action
- D.
  
  All of the above
Correct Answer
D. 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.
