Онлайн-тестирование: Test for seamans about Passage Planning with ECDIS
Can ECDIS be used to assist in the assessment of the manoeuvre to avoid collision with another vessel?
Yes, but not totally as the IMO Collision Regulations take precedent.
Yes, action can be taken just by watching the track of the other vessel.
No, because it cannot give target information on CPA and TCPA.
No, it should not be used at all. The IMO Collision Regulations should be followed.

Select from the options the correct answer to this question: Can saved voyage recordings be altered after the voyage?
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.

There is a contingency route planned.
The 2nd Officer is planning another voyage.
There are two routes displayed to be validated.

If not, dangerous objects not present in small scale charts could be missed.
ECDIS has no intelligence and has to be helped.
ECDIS cannot automatically load charts at the correct scale.
If there are raster charts on the ECDIS they would be used.
Select which option BEST answers this question. Is there one disadvantage with passage planning on an ECDIS?
Yes, the view of the chart is generally not as big as the paper chart.
Yes, there is, because the process is totally different to paper charts.
No, there is not, because all the appraisal information the planner needs is on the ECDIS.
No, there is not, because it saves the bridge team lots of time.
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…
Correctly apply the Regulations for Preventing Collisions.
Assess the situation from ECDIS then manoeuvre accordingly.
Check the CPA and TCPA if close alter course to port.
Stand on with caution as the target is the give way vessel.
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?
Yes – there is risk of collision as the vectors meet.
No – there is no risk of collision as the target vector does not point at own ship.
Not sure, because ECDIS should not be used for collision assessment.
No – risk of collision does not exist as the target will pass astern.
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.
Yes – there is risk of collision.
Not sure, because the ECDIS cannot be used for collision assessment.
No – risk of collision does not exist as the target will pass ahead.

What is the difference between route and track when passage making?
The route is planned. The track is where the vessel has been.
The route is where the vessel is now. The track is up ahead.
There is no difference between the two.

Revalidation is necessary when there have been chart updates.
Revalidation is necessary when it has been put out of monitor mode.
Revalidation is necessary when it has been removed from the display.
It would not need re-validating because once validated that is sufficient.

It is important because in the base or standard layer some objects will not be visible.
It is not important as the chart detail is always there to see.
It is important because as waypoints are entered an alarm will sound if one is on top of a symbol.
It is important because it is interesting to see what the vessel will be passing.

No – because there may be an unseen position error on the navigation signal.
Yes – because that is the meaning of track control.
Yes – because the bridge Officers are skilled at steering the vessel.
No – because at some waypoints the ECDIS will show an over shoot.
With an ECDIS in track control, should the vessel symbol always be on the route line?
Yes – because the system is set to follow the planned track.
Yes – because the bridge Officer will steer the vessel along the route.
No – as route mode is when the passage is planned.
No – because errors in the navigation signal send it off.
