This is an excellent video! I am just starting a small series of videos about all the different Earth flat map projections and I wanted to do one on the Mercator projection and how it is used for navigation. This video will be so helpful. I will certainly include a link to it in my video so people will come here and learn more. Thanks!
Very well explained sir one can understand the concepts easily if he is even doing self study thanks a lot sir plz make such various on rest of navigational chapters like gr8 circle,composite circle etc we all will be gr8 full to u thnx a lot sir🙏🏻
In the absence of Nories Table, MP can be calculated by using Scientific calculator Lat / 2 + 45 = Tan Log * 7915.7 - Sin Lat * 23.2669 (23.2669 can be rounded to 23.3) 27.25 / 2 + 45 = Tan Log * 7915.7 - Sin 27.25 * 23.2669 or 23.3 = 1,689.72 21* 7' / 2 + 45 = Tan Log * 7915.7 - Sin 21* 7' * 23.2669 = 1,288.31 Note: I used Scientific Calculator FX 995
Sir, At 10:05 you say that the distance is common. But as we look into the figure, the distance for plane sailing triangle is less than the distance for Mercator sailing triangle. Then how come they are common. I know that one possibility can be that both the triangles are almost equal and for practical use we can consider them almost equal but then that is why Mercator sailing is done, i.e when the curvature of Earth starts coming into play around 600M or so we can't use plane sailing. If we consider them equal then why in the first case do we need Mercator Sailing. Please be kind to clear my doubt sir. Regards Akshdeep Sharma
Greetings Akshdeep! I am glad you raised this question. Please pay attention to the words. Yes, the distance is common but I never said that it is equal. If you see both these triangles, you will agree to that fact that both these triangles are similar to each other. (By similarity of triangles). And only because they are similar to each other, we can superimpose them for the purpose of solving the questions and as a result the hypotenuse can be taken as common.
Sir you said while finding DMP Same name of lat are subtract and different name are add, but while in your given example they are of different name but you are still subtract them😔

Sir please make a video on Mercator sailing problem solving so that it would be a great help.
Will surely work on that. Thankyou for the suggestion :)

Fantastic ! 🙏 Appreciate very much 🙏
Sir is it a whole chapter in this video .. it is very good to have you as a teacher,tbh it really helped me a lot.Thank you Sir❤️
Glad to hear that. Keep watching & gaining knowledge.
Sir you should add more videos . The way of teaching in very comfortable.
very nice video... it helped me a lot to clear my concept...
Glad it helped! Keep watching the videos and keep gaining useful knowledge. Share as well!
best💌 one
It's very helpful sir... Could you please post some videos about.. great circle sailing
Sure. On it!
Very good explanation!
Now I am able to understand this video means a lot sir ❤️
Sir please make more videos of Navigation 🙏🙏
Thank you for explaining in such a great way . Are you a seafarer ?
Sir please made a video on Mercator sailing numerical 🙏🏻🙏🏻🙏🏻
Sure, will keep that in mind :) Thanks for the suggestion.

@@seashellshore9997 ohh.. this similarity thing did came in my mind but i just wanted to confirm it.
Thanks for clarifying and giving your time sir.😄
@@akshdeepsharma9252 Keep learning and help us reach out to more and more people who can benefit from this.Thankyou :)
Could you make a video on great circle sailing
Very well instructions sir !!
informative ...
Glad it was helpful!
Please explain day work questions
Will do it soon. Stay tuned!
Sir post great circle sailing please
Thankyou for the suggestion. Will work on it!

Cn u explain in hindi
That accent is harsh in my ears 😂 though I enjoy the video I couldn't finish it.
Can you please do a video on Great circle sailing
