It is not recommended to be used in an immediate action situation
- A.
Single turn
- B.
Scharnow turn
- C.
Williamson turn
- D.
None of the above
Correct Answer
A. Single turnExplanation
The correct answer is single turn. This means that in an immediate action situation, it is not recommended to use multiple turns or maneuvers. Using a single turn allows for a quicker response and reduces the risk of overcomplicating the situation. Multiple turns or maneuvers may take more time and increase the chances of making a mistake or losing control. Therefore, it is best to use a single turn in such situations.Rate this question:

Beaufort wind force that corresponds to moderate waves
- A.
Force 5
- B.
Force 6
- C.
Force 4
- D.

- C.
70 degrees latitude north or south
- D.
60 degrees latitude north or south
Correct Answer
C. 70 degrees latitude north or southExplanation
The correct answer is 70 degrees latitude north or south. This is because the geostationary INMARSAT system provides coverage up to 70 degrees latitude north or south. Beyond this latitude, the system's coverage becomes less reliable due to the curvature of the Earth and the positioning of the satellites in geostationary orbit.Rate this question:

Aircraft ditching into a swell should touch down the surface just after passage of a
- A.
Trough
- B.
Prong
- C.
Crest
- D.

Correct Answer
C. CrestExplanation
When an aircraft is ditching into a swell, it should touch down on the surface just after the passage of a crest. A swell refers to a series of long, rolling waves in the ocean. The crest is the highest point of a wave, while the trough is the lowest point. By touching down just after the crest, the aircraft can minimize the impact and avoid hitting the trough, which could cause the aircraft to submerge or become unstable.Rate this question:

The aeronautical mobile service uses what communication modulation for VHF telephony
- A.
DF modulation
- B.
Amplitude modulation
- C.
Rescue modulation
- D.
High modulation
Correct Answer
B. Amplitude modulationExplanation
The correct answer is amplitude modulation. In the aeronautical mobile service, VHF telephony uses amplitude modulation for communication. Amplitude modulation involves varying the amplitude of the carrier wave in proportion to the audio signal being transmitted. This allows the audio signal to be superimposed onto the carrier wave, enabling the transmission of voice signals over VHF frequencies.Rate this question:

Ditching condition whereby ignoring crosswind components and land parallel to the primary swell
- A.
In restricted visibility
- B.
During heavy weather
- C.
Winds 0-25 knots
- D.
Winds above 25 knots
Correct Answer
C. Winds 0-25 knotsExplanation
In winds 0-25 knots, it is possible to ditch an aircraft in restricted visibility during heavy weather conditions. The condition mentioned in the answer suggests that when ditching, the pilot should ignore crosswind components and instead land parallel to the primary swell. This means that the pilot should align the aircraft with the direction of the primary waves in order to minimize the impact and maximize the chances of survival during a water landing.Rate this question:

Neither a or c
Correct Answer
B. Both a & cExplanation
Civil vessels and aircraft may need to communicate with each other in both emergency situations and when communicating with SAR (Search and Rescue) facilities. In emergency situations, such as accidents or distress calls, it is crucial for civil vessels and aircraft to communicate with each other to coordinate rescue efforts and ensure the safety of those involved. Additionally, they may need to communicate with SAR facilities to provide information about their location, situation, and any assistance required. Therefore, both options a and c are correct as they represent different scenarios where communication between civil vessels and aircraft is necessary.Rate this question:

When is the best time to cancel distress message
- A.
When SAR is ready
- B.
When distress craft has been recovered
- C.
When nobody acknowledge
- D.
When assistance is on the way
Correct Answer
B. When distress craft has been recoveredExplanation
The best time to cancel a distress message is when the distress craft has been recovered. This means that the situation that prompted the distress message has been resolved and there is no longer a need for assistance. Cancelling the distress message at this point ensures that resources are not wasted and that emergency services can focus on other ongoing emergencies.Rate this question:

- D.
Wait
Correct Answer
D. WaitExplanation
The correct answer is "wait." In radio communication, "wait" is a procedural word used to indicate that the speaker needs to pause for a few seconds and standby for further transmission. It is a signal for the listener to be patient and not interrupt or respond until the speaker continues with their message.Rate this question:

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 usedExplanation
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.Rate this question:

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. HypothermiaExplanation
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.Rate this question:

Correct Answer
C. Scharnow turnExplanation
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.Rate this question:

Correct Answer
D. All of the aboveExplanation
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.Rate this question:
