A. 060°11’S B. 059°49’S C. 060°00’S D. 060°06’S Timestamp Intro 0:00 Question 0:20 Find Conversion Angle 02:14 Find Departure 03:36 Trigonometry 04:29 Closing 06:54 To find approximate latitude on a Great Circle track, we need to find the conversion angle. Conversion angle is the angle between the Rhumb Line Track and the Great Circle Track. The next step is to find the departure (distance along a latitude), from the start position to the middle point of the track. After that, you need to convert your diagram into a right-angle triangle. Because the Conversion Angle is reducing to zero at the mid position, the angle of the right-angle triangle is the average between the conversion angle at the initial point and the midpoint of the track. Finally, you can use trigonometry to find the distance between the Great Circle Track and the Rhumb line track at the mid-point of the track. Then convert it into degree and minute.
