Mercator's Scale - Charts - General Navigation ATPL

This video will discuss Mercator’s Chart Scale for ATPL General Navigation examination preparation. Four sample calculations are included in this video encompassing the following question type:
• Given scale at the Equator, find Mercator scale at some other latitude.
• Given Mercator scale at some latitude, find scale at the Equator.
• Given Mercator scale at some latitude, find Mercator scale at some other latitude.
• Given a fixed chart distance between meridians, find Mercator scale at a specific latitude.

I just can't thank you enough for the time and effort you put into making such information and easy to understand videos! ✅️
I hope you'll continue to make such incredible videos on others topic too ❤️

O really had to stop in between your video to appreciate you for these beautiful videos. The difference that I observe is that you talk with animations and if a person can't understand he can pause at contemplate upon what you said and then can fully understand. Other instructors say it and a student may lag and they usually lag...




Hats off to you man. 👏 you are spreading this most important lecture free to us.

Thank you. You helped me to hack Mercator scale calculations. It was something I couldn't get a clear picture of by any means.

I wanna ask this question. on a Lambert conformal chart the distance between meridians 5' apart along latitude 37' north is 9cm. the scale of the chart at the parallel approximates? am I still can use this method?
