  • 1

    What is the most vital information of any ECDIS system?

    Own ship position

  • 2

    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

  • 3

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

    Failure to cross-check

  • 4

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

    Master and watchkeeping navigators

  • 5

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

    good seamanship

  • 6

    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

  • 7

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

    Safety contour

  • 8

    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

  • 9

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

    Appraisal

  • 10

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

    The Bridge Team

  • 11

    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

  • 12

    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

  • 13

    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

  • 14

    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

  • 15

    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

  • 16

    What is the next step after setting the Safety Contour?

    Safety domain

  • 17

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

    AIS data

  • 18

    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

  • 19

    Dependency on traditional navigation techniques include following EXCEPT

    Knowledge of modern navigation

  • 20

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