Unformatted text preview: NAVG 212 Spring 2009 Name: Celestial Lines of Position: Chart Plot Sun LOPs (Lab H) C Piloting Techniques  Plot the Course(s), bearing(s), LOP(s)  Label Course(s), bearing(s), LOP(s)as necessary to comply with labeling protocols 1. Construct your plotting with the following parameters: • Mid-latitude is 43° North • Central Meridian is 140° West 2. At 0636 LMT on during morning twilight, , your position was determined to be: 43° 28’N , 142°11’ W. Local variation is 18 ° E and gyro error is 1 ° E. 3. From the 0636 position lay out a course line of 122 ° pgc, (109 ° psc). Use hourly DRs from 0700 -1300. Speed 20 kts. • What is the True Course? • What is the deviation of the standard compass (psc)? 4. What is predicted time of meridian passage of the Sun (LAN) on your track line.? 5. During the 0800 -1200 watch observations of the Sun and Moon are made. Plot the LOPs for these observations for During the 0800 -1200 watch observations of the Sun and Moon are made....
