![]() Line drawn perpendicular to True Azimuth of a celestial body at ITP, or at DR Lat. True Radar bearing of a point of land or Racon, calculated after correcting the relative or gyro compass bearing as stated above.ģ. Gyro error applied appropriately to gyro compass bearing.Ĭompass error calculated by appropriately combining Deviation from the deviation card, for the given compass course, and Variation as given in the chart / question paper, andĪpplied appropriately to the compass bearing.Ģ. Ships head applied appropriately to relative bearing. True visual bearing of an object calculated as follows : Preferably use the formula in all cases.Īfter completing the plot on the chart, draw a neat sketch of the plot on the answer sheet, which need not be to scale, and mark the appropriate symbols as stated above.Įrase all extra or unnecessary lines drawn on the chart, which are not relevant to the plot, to avoid confusing the examiner.ġ. If some data is calculated by using the Nories tables and not the formula, then mention the name of the table on the answer sheet. Merely calculating the values byĬalculator and writing the answer, will not be accepted by the examiner. the formula, values of each parameter and answer obtained. Show all calculations required for solving the problem in detail on the answer sheet i.e. If some correction is announced by the invigilator you may respectfully request for extra time which will normally be given. Problem only after receiving examiners instructions. Immediately proceed with the next problem and come back to the original Problem is available then start solving it.īefore starting a problem or after working part of it, if you realize that some data is inadvertently missing or apparently wrong, then inform the invigilator and seek his If all the necessary data for working the Read the question carefully and write the given data on your answer sheet, except the positions of lights, and double-check the same. There are 3 questions in section A (chartwork) and all are compulsory. State the times of various positions on the chart as stated in the question. If you use wrong symbols or no symbols then it would confuse the examiner and you Use appropriate symbols to indicate various parameters like course steered, CTS, CMG, current, celestial azimuth, celestial PL, transferred PL, DR position, estimated position andįix. Never use the angle markings on the parallel ruler.Īlways use the same edge of the parallel ruler when transferring courses and bearings from/to the compass rose.įor plotting a point or measuring its latitude and longitude, use the nearest parallel of latitude and meridian, or the compass rose, with the help of parallel ruler. Measure all bearings and courses by only using the nearest compass rose. ![]() Use transparent plastic protractor and parallel ruler or set squares. Erase all old lines from the chart before starting work, including all markings along the latitude and longitude scales, and in the compass rose.
