An ECDIS is required to display which informtation?
- A.
Hydrographic data, RADAR targets, ARPA vectors
- B.
Brightness, Darkness
- C.
Temperature, Density, Distance
- D.
Pressure, Vibration
Correct Answer
A. Hydrographic data, RADAR targets, ARPA vectorsExplanation
An ECDIS (Electronic Chart Display and Information System) is a navigational tool used on ships that displays electronic navigational charts. It is designed to provide essential information for safe navigation. Hydrographic data is crucial for determining the depth and characteristics of the water, while RADAR targets and ARPA vectors help in identifying and tracking other vessels and potential obstacles. Therefore, an ECDIS is required to display hydrographic data, RADAR targets, and ARPA vectors to assist mariners in making informed decisions and ensuring safe navigation.Rate this question:

ECDIS means:
- A.
Electronic Chart Display and Information System
- B.
Electric Chart Data and Information System
- C.
Electric Chart Display and Information System
- D.
Electronic Chart Data and Information System
Correct Answer
A. Electronic Chart Display and Information SystemExplanation
ECDIS stands for Electronic Chart Display and Information System. It is a navigation system that uses electronic charts to provide real-time information about a ship's position, course, and speed. It displays navigational data such as depth contours, buoys, and other landmarks, helping the crew to navigate safely. The system also integrates with other onboard sensors and systems to provide a comprehensive view of the ship's surroundings.Rate this question:

The most important reason for taking anti-seasickness pills as soon as possible after entering a liferaft is to _______________.
- A.
Reduce appetite by decreasing nausea
- B.
Prevent impaired judgment due to motion-induced deliriousness
- C.
Assist in sleeping
- D.
Prevent loss of body moisture by vomiting
Correct Answer
D. Prevent loss of body moisture by vomitingExplanation
Taking anti-seasickness pills as soon as possible after entering a liferaft can help prevent loss of body moisture by vomiting. Seasickness can cause nausea and vomiting, leading to dehydration. By taking the pills, the individual can reduce the likelihood of vomiting and therefore minimize the loss of body moisture. This is crucial in a liferaft situation where access to fresh water may be limited, and dehydration can worsen the overall condition of the survivors.Rate this question:

ECDIS is set with performance standard by IMO called:
- A.
TX 50
- B.
DP 90

A radar based constant up-date of cross track tendency.
- A.
Distance Off Danger
- B.
Parallel Indexing
- C.
Clearing bearing
- D.
Track Made Good
Correct Answer
B. Parallel IndexingExplanation
Parallel indexing refers to the process of maintaining a constant heading while navigating parallel to a reference line. In the context of radar, it involves continuously updating the cross track tendency, which indicates how much the vessel is deviating from its intended course. By monitoring this tendency, the navigator can make adjustments to ensure that the vessel stays parallel to the desired track. Therefore, parallel indexing is the most suitable explanation for the given answer.Rate this question:

This is the ship's electronic data base used in the ECDIS System.
- A.
Chart data base
- B.
Maps
- C.
Electronic Nautical Chart
- D.
Digital Chart
Correct Answer
C. Electronic Nautical ChartExplanation
The ship's electronic data base used in the ECDIS system is called an Electronic Nautical Chart. It is a digital chart that contains all the necessary information for navigation, including maps and chart data. This electronic chart allows for more efficient and accurate navigation as it can be updated in real-time and provide additional features such as route planning and collision avoidance.Rate this question:

The Component of the IBS that allows a navigator to see an integrated navigation and tactical display and to avoid navigational hazard is:
- A.
RADAR
- B.
Control system
- C.
System display unit
- D.
Tactical display unit
Correct Answer
A. RADARExplanation
The correct answer is RADAR. RADAR, or Radio Detection and Ranging, is a component of the Integrated Bridge System (IBS) that allows a navigator to see an integrated navigation and tactical display and avoid navigational hazards. RADAR uses radio waves to detect and track objects, such as other vessels, land masses, and weather systems, providing real-time information on their positions and movements. This information helps the navigator to make informed decisions and safely navigate through potential hazards.Rate this question:

Which of the following statement is TRUE regarding automatic identification systems (AIS)?
- A.
AIS provides near real-time information regarding another vessel's speed over ground and heading regardless of visibility.
- B.
AIS will not provide information on another vessel if that vessel is indistinguishable in radar sea clutter.
- C.
AIS can be relied upon as the sole means to determine course changes due to other AIS equipped traffic.
- D.
AIS is designed to replace ARPA, maneuvering boards, and visual bearing as a means to ascertain the risk of collision.
Correct Answer
A. AIS provides near real-time information regarding another vessel's speed over ground and heading regardless of visibility.Explanation
AIS provides near real-time information regarding another vessel's speed over ground and heading regardless of visibility. This means that AIS can give accurate and up-to-date information about the speed and direction of a vessel, even in situations where visibility is poor or limited. This is important for navigation and collision avoidance, as it allows vessels to have awareness of other vessels' movements and make informed decisions to avoid potential collisions.Rate this question:

Chart information details to be used in ECDIS should be the latest edition of information originated by a government-authorized hydrographic office and conform to the standards of (the) _________.
- A.
US Coast Guard
- B.
International Maritime Organization
- C.
NASA
- D.
International Hydrographic Organization
Correct Answer
D. International Hydrographic OrganizationExplanation
The correct answer is the International Hydrographic Organization. This organization is responsible for coordinating the activities of national hydrographic offices and promoting the development and use of hydrographic information for navigation and other maritime purposes. The chart information used in ECDIS should be the latest edition of information originated by a government-authorized hydrographic office and conform to the standards set by the International Hydrographic Organization.Rate this question:

Which information must automatic identification systems (AIS) automatically provide to appropriately equipped shore stations, vessels and aircraft?
- A.
Destination
- B.
Draught
- C.
ETA
- D.
Vessel's course
Correct Answer
D. Vessel's courseExplanation
Automatic identification systems (AIS) are designed to automatically provide information to shore stations, vessels, and aircraft. One crucial piece of information that AIS must provide is the vessel's course. This information is important for navigation and collision avoidance purposes, as it allows other vessels and aircraft to track and predict the movement of the vessel. By knowing the vessel's course, other entities can make informed decisions about their own navigation plans and take appropriate actions to ensure safety at sea.Rate this question:
