Q1.An icon (target ring with a dot inside) is visible in the top right corner of the screen and disappears when the indicator is pressed. What is that for?It is used to acknowledge warning when own vessel is on a collision course.
It is used to hide all radar and AIS targets.
It is used to acknowledge a warning when another vessel is coming too near.
It is used to locate own vessel position when own vessel position is out of chart view or not followed automatically.
Correct Answer!
Q2.A ship is sailing in a straight line in an area with a constant strong sideways current and constant engine power. The own ship velocity vector(s) are turned on. Which statement is true?
The velocity vector will show the future position of the ship only for the 'over ground' vector.
The velocity vector will show the future position of the ship only for the 'through water ' vector.
The 'prediction' vector will show the future position.
The route will show the future position.
Q3.What is the backup arrangement in the Tool panel used for?
To synchronize SENC geodatabases, mariner objects, routes, permits and configuration file between several ECDIS units so they are present and updated on all ECDIS units.
To synchronize SENC geodatabases, marine object, routes and configuration file with the Navbox or planning computer.
To backup SENC geodatabases, marine object, route, data permits and configuration file to an external USB stick.
Correct Answer!
Q4.You wish to show approaching radar targets as dangerous within distance of 3 nm from own ship on the chart. How?
You change radar target TCPA to 120 seconds.
You change radar target CPA to 3 nm.
You change radar targets as dangerous to own vessel to 3 nm.
Adjust your radar equipment to report dangerous targets to the ECDIS at 3 nm.
Q5.Where do you install the Scheme Administrator Certificate (SA Certificate)?
By going to “Settings” then “System” and clicking on “SA Certificate” and click refresh.
Get the update from sacertificate.danelec-marine.com.
Call the ECDIS manufacturer to get a new root certificate.
Correct Answer!
Q6.You are told to submit a user permit of the ECDIS for new charts application. Where can you find it?
Go to “System information” in “Settings” where you can save the User permit code to a USB stick.
Go to “Install charts” in “Nav data”, look for list of installed permits.
Call the ECDIS supplier to ask for the user permit.

Q7.The graphical index of a database is turned on in the Chart library. What is that for?
It displays the coverage boundary of the ENCs in a particular database.
It switches on the database for viewing purpose.
It displays the edition number of the dataset.
Q8.You are to make a first manual update of an existing object, a buoy, on a chart. How do you start making the update?
By opening “Manual update” in “Nav data” panel, select “Modify object” and right click in the chart to pick up the object.
By loading an update CD.
By pressing the Ctrl-'U' key on the keyboard.
Correct Answer!
Q9.What is the difference between 'safety contour' and 'safety depth' ?
Safety contour is used for anti-grounding alarms and is shown as a line. The safety depth determines the color of soundings displayed.
Safety contour determines the area colored as safe waters for the ship. The safety depth is the additional depth necessary beneath the keel.
Safety depth is used to determine and generate grounding alarms. Safety contour is used to color the chart grey at safe areas.
Safety depth is the maximum depth, that the ship can sail safely in (i.e. depth<1000m). The safety contour is the contour of the ship on the chart.
Safety depth is the draft of the ship when loading at a maximum. Safety contour is the maximum ship beam (width).
Q11.What is the difference between 'deep contour' and 'shallow contour' ?
The deep contour is the draft of the ship. The shallow contour is the part of the ship over water at light loads.
Deep contour is where the ship beam (width) is okay, the shallow contour shows places too narrow for the ship.
The shallow contour shows where it is too shallow for the ship to operate. The deep contour shows areas with very safe depths.
The shallow contour is between medium shallow and very shallow areas. The deep contour determines deep water areas.
Shallow contour indicates shallow waters, deep contour indicates areas where it is deep enough for the ship to sail.
