What is the most vital information of any ECDIS system?

Own ship position

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.

Turn information

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

Failure to cross-check

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

Master and watchkeeping navigators

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

good seamanship

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.

Check Route Function

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

Safety contour

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

The second Officer creates the draft plan

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

Appraisal

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

The Bridge Team

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

Proper appraisal

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?

Navigators

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?

Route monitoring

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?

Appraisal

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?

Higher

What is the next step after setting the Safety Contour?

Safety domain

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

AIS data

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

Alarm management and appropriate use of tools

Dependency on traditional navigation techniques include following EXCEPT

Knowledge of modern navigation

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

Radar image overlay

affects the appearance of spot sounding

deep contour

value should not be less than UKS + maximum draught

shallow contour

for route check and alarm generation

safet depth

it triggers the alarm

guard zone

useful tool in narrow areas

parallel index lines

passage plan must have

a contigency plan

best option checking ship's position

radar

can be equal to or above safety depth

safety contour

defines the area in radius and width

sector

defines the area and length

vector

vital to the operation of ecdis

safety depth

updates information in real-time

AIS

ultimate safety layer

safety frame

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

radar overlay

a gps datum

WGS-84

ECDIS alarms and indication are EXCEPT

Exceeding of speed through the water

ECDIS will provides indication EXCEPT

system test successful

ECDIS indication are required for the following EXCEPT

chart in normal scale

Five mandatory alarms on ECDIS are EXCEPTs

failure of echo sounder

Alarms are required for the following EXCEPT

approaching tss

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

deep water contour

Indicative of areas where ship will experience squat.

deep contour

What will define the look ahead area in ECDIS

sector/vector

It affects the display of soundings.

safety depth

What is considered as the grounding depth?

shallow contour
