PLOTTING EXERCISE SEVEN - QUESTIONS ONE NAME: 1 Your ship is on a course of 130° T and its speed is 28 kts.At 1500 a contact was observed bearing 090° T at 12.0 miles at 1505 the bearing was 091½° T at 9.0 miles, and at 1510 the bearing was 095° T and the. In practical exercise 1 you will plot the range and bearing of the given target in intervals of 6 minutes on a radar transfer plotting sheet. You are not given a course and speed for your vessel, this is intended for you to familiarize yourself with the initial start of the E-R-M triangle, AND THAT IS THE RML (relative motion line).
- Determine kinematic data of a target like CPA (Closest point of approach) and TCPA (Time of CPA)
- Determine evasive maneuver by turn to starboard, left and speed reduction with single target.
- Determine the current.
- Determine maneuver to escape.
- Determine rescue maneuver.
- Determine evasive maneuver by turning to the right and to left with two targets.
In addition to the analytical resolution is a graphics representation on the radar sheet, with scale speed and adjustable distance in manual or automatic mode.
Also in the graph it is selectable the representation of the true motion or relative motion.
3 practice plotting exercises. 2 plotting exercises on a radar simulator by transfer plotting to a radar transfer-plotting sheet (90% on each required to pass). You will plot targets graphically (e.g. Rapid-radar plotting technique) to correctly derive solutions and determine own ship’s position while underway. Course Instructions 1. Plot target position X at 6. Minute intervals (= 0.1 hour) 2. First plot = O (Original) 3. Last plot = A (Actual) 4. Draw O - A the blue line. Past P the centre of the plot (your position) 5. Draw a line from P (in red) to meet the blue line at right. This is the CPA. Find the Time to CPA = (A-C / O-A) x Time for OA.
Plot target position X at 6 minute intervals (= 0.1 hour) O A. First plot = O (Original) 3. Last plot = A (Actual) 4. Draw O - A the blue line past P the centre of the plot (your position) Finding the Closest Point of Approach - CPA of a Target 2 1. Plot target position X at 6 minute intervals (= 0.1 hour) 2.
