Your answer is correct:

No.
7

Select from the options the statement that best describes the information that should be recorded by ECDIS for the whole voyage:

ECDIS should record the entire route with time marks.

Your answer is correct:

A time and date related happening.
9

Select the one option, that correctly completes the following statement: ECDIS Automatic Voyage Recording is best described as…

Your answer is correct:

ECDIS saving voyage data in accordance with ECDIS regulations.
10

Select the option which best describes why ECDIS shows two connected routes on the display, one red the other orange in colour:

Your answer is correct:

There is a contingency route planned.
11

Select the option which correctly completes the following statement: When validating a route using ECDIS, it is important to have all available charts, because…

12

Select which option BEST answers this question. Is there one disadvantage with passage planning on an ECDIS?

Your answer is correct:

Yes, the view of the chart is generally not as big as the paper chart.
13

The illustration shows a vessel on passage with ARPA radar target information over laid on ECDIS, and the vector length is 12 minutes. Which option BEST completes the following statement: The action that should be taken is to…

Your answer is correct:

Correctly apply the Regulations for Preventing Collisions.
14

The illustration shows a vessel on passage with ARPA radar target information over laid on ECDIS, and vector length is 12 minutes. Is there any risk of collision with the target?

Your answer is correct:

Yes – there is risk of collision as the vectors meet.
15

The illustration shows a vessel on passage with ARPA radar target information over laid on the ECDIS, and the vector length is 12 minutes. Is there any risk of collision with the target?

No – risk of collision does not exist.

Your Answer:

Yes – there is risk of collision.
16

What happens to ECDIS functionality when a voyage playback is running?

Your answer is correct:

The ECDIS stops working in real time.
17

What is the difference between route and track when passage making?

Your answer is correct:

The route is planned. The track is where the vessel has been.
18

When does an object have an isolated danger symbol displayed on it?

Your answer is correct:

When an object has less depth than the safety depth or contour setting.
19

When will an ALARM sound on an ECDIS operating in track control?

Your answer is correct:

When approaching a wheel over position.
20

Which answer BEST completes the following statement: Insert mode when route planning with ECDIS means…

Waypoints are being added to a route list.
21

Your answer is correct:

Bringing together a displayed radar return and AIS target symbol.
22

Which answer BEST describes how a dangerous AIS target is seen on the ECDIS display?

Your answer is correct:

It shows with a red triangle and vector.
23

Your answer is correct:

It is a position on the vessel common to all sensors.
24

Which answer BEST describes the effect on the chart display when the ECDIS safety depth value is set?

Your answer is correct:

Depth values shallower than the depth are highlighted in bold.
25

Which answer BEST describes the information seen on the ECDIS route monitor page?

Your answer is correct:

Basic route information as the vessel proceeds.
26

Which answer BEST describes the use of the predictive vector on an ECDIS?

Your answer is correct:

If set to the correct length it will help protect against grounding.
27

Which answer BEST describes how the safety depth contour is seen on an ECDIS?

Your answer is correct:

As a solid line highlighted in bold.
28

Which answer correctly completes the following statement: On the ECDIS, spot depth soundings with less value than the safety depth setting is shown…

Your answer is correct:

As bold figures.
29

Which answer correctly completes the following statement: Setting the turn radius on an ECDIS is important because…

Your answer is correct:

The turn catenary on the display is set from it.
30

Which answer correctly completes the following statement: The conning position, GPS aerial position and radar antenna position are adjusted into one position on the ECDIS that is called the…

Your answer is correct:

Consistent common reference point.
31

Which answer correctly completes the following statement: The own vessel past track on ECDIS is shown as…

Your answer is correct:

A solid black line.
32

Which answer correctly completes the following statement: The value of cross track limit when validating a route is important because…
