Under whose responsibility remains the ship's safety and maintaining it on a safe route?

Indicative of areas where ship will experience squat.

Who recommended getting in touch with the passage plan and making sure that the ship would navigate by the developed plan?

defines the area and length

What stage such as safety contours and safety depths should be set for ocean passages, to provide early warning of landfall, hazards, or the possibility of increased traffic?

Five mandatory alarms on ECDIS are EXCEPTs

Dependency on traditional navigation techniques include following EXCEPT

This can usually be entered by the rate of turn or radius. The system will normally calculate one from the other one, and display both parameters using the planned speed for the leg.

a gps datum

Which other information ECDIS will display in case of failure of radar input video?

In voyage planning, using an ECDIS is the same as with paper-based navigation. However, making a passage plan utilizing the full aspect of a type-specific ECDIS needs some careful consideration. Summarized below are some key points EXCEPT

Which process is the first to take to broadly consider the routing and consider factors affecting the voyage?

It is normally set to twice the draught or as defined by user.

What is the most vital information of any ECDIS system?

for route check and alarm generation

Alarms are required for the following EXCEPT

defines the area in radius and width

What is the next step after setting the Safety Contour?

best option checking ship's position

What will define the look ahead area in ECDIS

What process should be done in collecting information from the relevant publications needs to be carried out before plotting a route on the ENC?

The principles of _ and maintaining a proper lookout apply when navigating electronically.

Failure to adjust settings appropriate to the situation may result in too much or too little information. What should be the cause?

can be equal to or above safety depth

it triggers the alarm

It affects the display of soundings.

The navigating officer should make use of which facility after planning the passage to ensure that the vessel will not encounter navigational hazards on the planned route.

Who should be aware that a geometrically incorrect alarm will be displayed if the distance between two waypoints is very short or if the turn is very sharp? In such a case, the radius and/ or speed should be adjusted to clear the alarm by whose responsibility?

What settings such as safety contours and safety depths should be set for ocean passages, to provide early warning of landfall, hazards, or the possibility of increased traffic?

What is considered as the grounding depth?

Which setting will alert the navigator that the vessel is approaching shallow water?

passage plan must have

vital to the operation of ecdis

useful tool in narrow areas

Tendency to assume that the displayed position is correct without verifying position integrity by some other means.

value should not be less than UKS + maximum draught

affects the appearance of spot sounding

green spots or image appeared on ecdis originates from...

At what time should ECDIS give an alarm if, within a specified time set by the navigator, its ship is likely to cross the safety contour?

What is the best means of verifying cartographic data and the output of navigation sensors?

updates information in real-time

ECDIS alarms and indication are EXCEPT

ECDIS will provides indication EXCEPT

ultimate safety layer

ECDIS indication are required for the following EXCEPT
