Great Circle Sailing - I

This video is intended to clear all required concepts about calculation of great circle distance, initial course and the final course. The video also includes 3 numerical to clear the concepts. Suggest, viewer watches it on large TV with focus.

[@Kari_bhai]

Everything is understood sir....but find the course ...I m facing problem..can u please explain this.... whether we add 180 or 360-

[@MarineGurukul]

The Initial or Final Course could be:
1) same as calculated angle
2) 180 - calculated angle
3) 180 + calculated angle
4) 360 - calculated angle
Please see the video again. If still in doubt, you may write again.

Sir in a great circle question, where the the higher latitude is north ...but vertex is not aked in question....i took the sputh pole instead pf North, i got same initial nd final courses as others, will we not get marks on it?? Kindly telle sir??

[@vincentjinal9167]

The vertex.....How to find the vertex?

[@francis5786]

Sir, Can we solve great circle sailing questions using the method used in Capt. Subramanian book (practical navigation) for competency exam?

[@MarineGurukul]

Which method? A, B, C tables or something else?
Anyway, you may use any method that is right.

Francis, in the age of scientific calculator, the use of nautical tables is losing relevance.

[@jahandave2057]

In the last question, we can find the quadrantal value of the true course and determine the direction she'll travel in. For 210° it's S30E.

[@MarineGurukul]

In great circle sailing courses changes at every meridian (exceptions apart). So, any course will state heading at that point - not necessarily representing direction d'lat & d'long between departure & arrival positions.
Best Wishes

[@ajaymarathe7936]

Sir there is mandatory to write sides
Like INITIAL COURSE N50E OR not
Thanks with regard sir it is really great ful easy to understand

[@MarineGurukul]

The courses may be stated in 3-figure notation or quadrantal notation - whatever you may be comfortable with.
Good Luck

Sir , Measuring courses is very confusing can you please tell some technic to measure courses without confusion.

[@MarineGurukul]

Did not get your question.
Once the angles A & B of the spherical triangle are calculated, is it obtaining of Final & Initial Course from there?
For sure would help you if your doubt can please be clarified. Thanks
