remember...the great circle route IS the shortest distance between 2 points on earth so most things that travel the shortest distance would.


also flew many a NDB approach....try it in a low, slow helo....only good news is lot's of options when you broke out...

I think everyone said this already, but it is both a straight line and a great circle route.

That's why I checked it out using coastal Explorer, which makes great circle routes as I have it set up.

Hi Richard,

Did you compass start pointing in weird directions when you tracked northwards on your trans-Atlantic trip?

I am glad to see some interesting comments on this thread, and have enjoyed reading those posted by others.

My Pet Peeve: Mercator Projection wall maps mislead people into thinking continents are a certain size, because of the distortions caused by the projection.

I often point out this difference (distortion) to children when I see they have a globe, as I want them to see that the real relative size of the continents (shown on the globe) is much different than what is shown on a typical wall map in their room or in their books. The visible difference can be astonishing.

For example, Greenland looks HUGE on a Mercator map, but is much smaller on a globe.

Similarly, Africa looks big on a Mercator map, but not as large as it really is (on a globe).

Simply put, as one looks at the Mercator maps, the further from the equator (closer to poles) one gets, the more distortion there is shown, with the land masses being stretched (enlarged) as you get closer to the poles.

Clip from an article: "Created by Flemish cartographer Gerardus Mercator in 1569, the Mercator projection preserves direction, instead of size, making it useful for navigation."
_____________

I love geography, so when I see a chart or map, I am drawn to it.

Here are a few illustrations to show the relative size of Africa to other countries and to Greenland. These illustrations are based on actual surface area comparisons.

Notice that Africa is about twice as large as the former Soviet Union!

Notice that the Continental USA and Europe and China AND India could ALL fit inside of Africa! That is HUGE!

Notice that Greenland is actually MUCH smaller than Africa, only about 1/14th the size of Africa, now go look at a typical Mercator map where Greenland appears about the same size as Africa, because of Mercator distortion. The second illustration shows a blue Greenland overlaid on top of a pink Africa, in both Mercator and actual size.

I am also including one projection that says it shows the true size of the land, so it may look a bit distorted or odd, as our minds are accustomed to the Mercator projection maps.
