Funny how Atlanta is further way. You would think it is closer because it is further south.


For very long distances the flat rectangular map can be very deceptive


When the POTUS went to Nelson Mandela's funeral he left from Andrew's AFB (ADW) and stopped in Dakar (DKR) to refuel . It must be a logistics nightmare to stop AF1 just to refuel. Normally, I think they try and schedule the plane so that he doesn't need to stop just to refuel, but as this trip was unplanned it wasn't possible to set up an intermediate visit.

The Secretary of State only has a B757 so he/she must stop to refuel frequently.



Ghanian President urged United in 2011 to put in a nonstop between Houston and Ghana as the Ghanian oil industry was booming.

When United received one of the Dreamliners they did comply, so there is another recent example of a nonstop to SS Africa (6,339 miles).

When the POTUS went to Nelson Mandela's funeral ...


I wonder what the cost to taxpayers was for that trip. Not to mention the carbon footprint.

When President Clinton went to Africa in 1998 the estimate was in addition to Air Force One, there were five passenger planes flown for 251.4 hours at an average of $10K per hour. The five other passenger planes carrying 1302 people. In addition there was a whopping 3257.5 hours of air time of Strategic lift aircraft and Aerial refueling aircraft. MASH units were set up to have hospitals available so no one would have to be treated in a local hospital. The visit taxed all military operations in Africa at the time.

Personnel
Department of Defense 904
Executive Office of the President 205
U.S. Information Agency 103
Department of State 60
Department of Transportation 9
Agency for International Development 6
Department of Labor 6
Department of Agriculture 3
Department of Commerce 3
Customs Service 1
Immigration and Naturalization Service 1
Department of the Treasury 1
Total 1,302

Ghana, Uganada, Rwanda, South Africa, Botswana, and Senegal had never seen anything like it.

How about this rectangular map split along the Ural mountains in russia? It shows the five longest air flights in the world including the two upcoming ones this year (SFO-SIN in June, and DOH-AKL in Dec)


DOH AKL 118° (SE) 116° (SE) 9,032 mi Qatar Airways December 2016
DXB AKL 118° (SE) 116° (SE) 8,824 mi Emirates
DFW SYD 249° (W) 245° (SW) 8,578 mi Qantas
SFO SIN 301° (NW) 288° (W) 8,446 mi United June 2016
ATL JNB 102° (E) 107° (E) 8,439 mi Delta

Then stick with the polar projection to show the next five longest routes


LAX AUH 007° (N) 355° (N) 8,390 mi Etihad
LAX DXB 007° (N) 354° (N) 8,339 mi Emirates
LAX JED 024° (NE) 012° (N) 8,332 mi Saudia
LAX DOH 010° (N) 358° (N) 8,306 mi Qatar
IAH DXB 030° (NE) 027° (NE) 8,168 mi Emirates

The FAA defines a polar route as anything that heads north of 012° (N), so strictly speaking only 3 of these routes are "polar". But 4 of 5 of them go above the Arctic Circle.

These routes will all be put in the shade when SQ resume SIN-EWR non-stop in a couple of years time. The configuration will be interesting. Will they be able to run it profitably with an economy class or will it be all business class as it was previously?

Overall the polar projections make the routes appear more sensible. Many times an equatorial projection makes it look as though airlines prefer the scenic routes, when logic dictates the shortest route every time.

What both do is give a more accurate impression of how vast the Pacific is.

How about a Vignelli 'abstract simplicity' map... similar to the subway maps that show inaccurate physical locations but stylized relationships between locations.

This would allow a representation of the world in more or less familiar locations of the continents and countries but would allow 'shrinking' of the oceans so that the important parts (take offs and landings) are shown but the lesser important, miles and miles of endless ocean are, although plainly shown, not given prominence simply due to their size.

This would allow countries and cities to be in large type and oceans to be depicted more as large ponds.

EWR SIN 003° (N) 016° (N) 9,534 mi *
DOH AKL 118° (SE) 116° (SE) 9,032 mi
DXB AKL 118° (SE) 116° (SE) 8,824 mi
LAX SIN 303° (NW) 291° (W) 8,770 mi *
DFW SYD 249° (W) 245° (SW) 8,578 mi
SFO SIN 301° (NW) 288° (W) 8,446 mi
ATL JNB 102° (E) 107° (E) 8,439 mi

* route from 2004-2013, due to be restarted 2017-2018 on Singapore Air
If those two routes are restored, then one is polar, and one crosses the tropics

The two new routes look better on the polar map

EWR SIN 003° (N) 016° (N) 9,534 mi *
LAX SIN 303° (NW) 291° (W) 8,770 mi *
LAX AUH 007° (N) 355° (N) 8,390 mi
LAX DXB 007° (N) 354° (N) 8,339 mi
LAX JED 024° (NE) 012° (N) 8,332 mi
LAX DOH 010° (N) 358° (N) 8,306 mi

* route from 2004-2013, due to be restarted 2017-2018 on Singapore Air







If nonstops to India and bringing Mexico and Panama City into the Emirates fold happens, we could get an explosion of ultra long distance routes

https://en.wikipedia.org/wiki/Non-stop_flight#Longest_flights

I added the images into Wikipedia article, sticking with rectangular for the longest (as per your preference) and avoiding any bizarre projections .
Let's see how long they stay.

The projections stayed about 5 hours on wikipedia. Somebody took them down because hey don't like polar projections.

I still think that polar is the easiest way to view flights from one northern hemisphere city to another. There are 30 routes on the list with 5 being flown by different airlines. Out of the remaining 25 unique routes, 20 are from one northern hemisphere city to another.
