Thanks buddy, appreciate the feedback 😊🙏

[@Prasangaarachchi]

sir can you do some SQA questions regarding the passage plan

[@hi6747]

Hi, I am quite interested in Great Circle Map. Can we share information?

[@namanchaturvedi8151]

Sir, Very well explained I have a doubt about how to draw rhumb line course on gnomonic charts?

[@marinerbhutto213]

Thankyou sir

[@himanjayawardene9358]

why do u prefer to take way points every 5 degrees when transfering to mercator charts

[@SteeringMariners]

Himan, you can actually choose any interval of longitude (5 degrees is a popular method). Since great circle courses cannot be drawn on Mercator charts, the aim is to choose waypoints at close intervals and then transfer them to Mercator charts.

Attempt to draw a great circle route on a north pole azimuthal equidistant map. You’ll find out the routes become perfectly straight lines.

If any of this flat earth crap were true we wouldn't be using gnomonic charts. Putz.

@@marcg1686 lol if the globe earth were true you wouldn’t need a cartoon for a profile picture

[@marcg1686]

@@REALStinkyCash We use gnomonic charts to map arc lengths of great circles. Any 'thoughts'?

[@REALStinkyCash]

@@marcg1686 A Great Circle route on a sphere is just a fancy way of saying traveling in a straight line in reality. It’s theoretical. And if you understood the flat earth model, you would understand how the information Translates perfectly. Only one of us is well-versed in both the flat and globe models. So you should probably learn both sides of a debate before entering the debate.

@@REALStinkyCash So we live on a flat earth and yet no flat Mercator map projection is adequate for navigation. Tells us all we need to know.
