THE PROCEDURE FOR DETERMINING OWN SHIP NEW COURSE AND SPEED TO REDUCE THE RISK OF COLLISION IS GIVEN BELOW
course to pass at specified cpa
2
Every vessel shall use all available means appropriate to the prevailing circumstances and conditions to determine if risk of collision exists.
risk of collision
3
If target does not follow aling the RML due to his change of course and or speed you can find new cpa
speed and course change of other ships
4
When working with the vector triangle there is three rules that must be remembered
course to avoid
5
Is dependent upon a feature normally provided with a true motion radar: some form of electronic bearing line tyat can hold the range and bearing to which set.
practical solution for cpa in true motion mode
6
Has been used for many years. It was defined by william burger in the radar observers hand book 1957 as equidistantly spaced parallel lines engraved on a transparent screen which fits on the PPI and can br rotated.
parallel indexing
7
The distance of an object when abeam if the vessel was to pass the navigation mark.
cross index range “C”
8
The distance which and object tracking on a parallel line would be on a new track line ( ahead of or behind the beam bearing of the. Object)
Dead Range “D”
9
The point which the actual manuever is made to insure that the object being “indexed” is on the new track line traking into account the advanced and transfer of the vessel.
wheel over point “W”
10
The vessel should be dead in the water or nearly so and the anchor can be dropped
anchoring point
11
can be drawn that intersect two points of land
parallel line
12
Based on the vessel manueveribg characteristics with respect to advance and transfer in order to ensure that the fixed navigation aid will track down the parallel line fir the new course
wheel over point
13
Determine the distance ahead or astern of the beam bearing of the fixed navigation aid at which point the aid should be tracking on a new parallel line.
Dead range
14
Is measured from the origin of the display to a point that is perpendicular to the parallel line.
the cross index range
15
Is a tracked as it “moves down” the parallel line.
