a) additional labelled lines of position
b) bearings, FIXES, times, change of speed
c) all of the above
Answer:

3. To label the true course on a chart using the CPS Course plotter, draw a straight line between point of departure and destination and:
a) with the edge of the protractor pointing north read the course
b) with the edge of the protractor along the line rotate the grid with pointer pointing north read the course at the pointer
c) with the edge of the protractor pointing east-west rotate the pointer of the grid towards north and read the course
d) none of the above
Answer:

4. To mark a DR position on a chart use:
a) a semicircle on the course line and mark it with the time
b) a circle on the course line and mark it with the time
c) a square on the course line and mark it with the speed
d) None of these
Answer:

5. A course line is labelled with:.
a) the magnetic course above the line and the true course below
b) the true course above the line and the magnetic course below the line
c) the true couse above the line and the speed below the line
d) the magnetic course above the line and the speed below the line
Answer:

6. To mark a bearing to an object on a chart:
a) mark the magnetic bearing above the line and the time below the line
b) mark the true bearing above the line and the time below the line
c) mark the true bearing above the line and the speed below the line
d) mark the true bearing below the line and the time above the line
Answer:

7. A FIX is marked on a chart by:
a) drawing a straight line of two LOPs to the point where they intersect the course line and marking that point with a circle, the time and the word FIX
b) drawing a straight line of two LOPs to the point where they intersect each other and mark that point with a circle, the time and the word FIX
c) placing a circle on the chart and marking it with the word FIX followed by the speed
d) placing a circle on the course line and marking it with the word FIX followed by the time
Answer:

8. The course line should be marked with:
a) the DR position at least every hour
b) the DR position at least every half hour
c) a fix position at least every hour
Answer:

9. Which of the following LOPs (Lines of Position) need NOT to be labelled with time above and bearing below:
a) two natural features which can be brought into line from a boat if they are shown on the chart
b) artificial ranges which are shown on the chart of the area
c) neither of the above need to be so labelled
Answer:

10. If two bearings plotted on a chart do not intersect the DR course line we should:
a) plot the point and label it as a DR
b) ignore the fix
c) plot the fix and start on from this point
Answer:

11. A back bearing on a point, at a distance directly behind us, which is less than the reciprocal of the track indicates:
a) our boat is to the left of the track
b) our boat is to the right of the track
