Its simple trigonometry, Dave.
No, it's not quite as simple as you think, because...

Each degree is 60 nautical miles.
That's true only for degrees of latitude.  Degrees of longitude have no consistent value in RET or FET.
I think you will find I only used degrees of latitude distances to make the calculation. It is because longitude is the differentiator between a flat and globular earth that there is a distance discrepancy. You are excused. You won't be able to help. Your maths isn't up to it.

For the more common mono-pole FE map, you would be better off using polar geometry for your calculator.
I did.

For the bi-polar FE map, I have no idea of what kind of geometry would work.
No, I don't suppose you do.

Just so I am clear, the vertex of the 151 degree angle is at the North Pole?

You can calculate it anyway you like sweet-cheeks. That's just the way I did it in about 5 mins.

So the answer to my question is yes.

Is your value of 60 nautical miles/degree based on observation of Polaris?

The definition of a nautical mile.

Why did you decide to use a unit that is defined by a round earth coordinate system?

Its 1852 meters regardless of the shape of the earth.

It was standardized because of the oblateness of the Earth, but the measurement, especially as it pertains to the length of a degree, most definitely has to do with the shape of the Earth.

Please see the FAQ dimensions for a flat earth. We have the same distance North to South pole. The nautical mile is valid for flat earth.

If that is your contention then fair enough.  As a side note the diameter is not mentioned in the FAQ.

Well it should be. Tausami must have not added it to the FAQ when the new wiki was built. That boy needs to be flogged.

I noticed a problem. According to your method Buenos Aires and Sydney should be 16,571 miles apart which is approximately 9,000 miles further than the RE number. It takes approximately 15 hours to fly this journey. If the FE distance is right, that means a commercial jet can achieve speeds of over 1,000 miles an hour, or just under Mach 2, which i think you will agree does make sense.

I struggle to believe you haven't had this debate before.

This thread is for a flat earth tool set to give you handy calculations like that. If you want to moan about the theory, go make a separate thread and try to find someone who is willing to do that debate all over again.

It's not very handy if it gives incorrect answers is all I am saying.

The calculator would be correct. Your understanding of the theory is a subject for another thread.

The formula for the length of lines of longitude (in kilometers, because this is science) on the FE monopolar map is:

445.277963%2890-x%29

Where x is the latitude

Well it should be. Tausami must have not added it to the FAQ when the new wiki was built. That boy needs to be flogged.

I believe it was removed because there was some contention about what, exactly, it was. The diameter and circumference listed in the old FAQ didn't add up, and no one could decide which number was correct. I'm personally not actually sure where they came from.

That's how far the horizon is, not how far you can see.

What is x in this case and what are the units?
