Creating Flight Plans for Flat Earth

Thursday, September 07, 2017 - 01:37 | Author: wabis | Topics: FlatEarth, Aviatic, Interactive | Comments(9)
This App lets you create a Flight Plan based on the Flat Earth Model.

Note: This Flight Plans must not be used in real flights, because the plans produced by this App are not accurate, because the earth is not flat but a globe.

This App is an answer to the Flat Earth Challenge - 9 months later Flat Earth Airlines is still grounded from the pilot Wolfie6020 to Flat Earthers, to produce a Flight Plan based on the Flat Earth model, so it can be compared to real Flight Plans. Since after 9 months no Flat Earther was able or willing to provide such a Flight Plan, I decided to create this App. Just for fun.

Flight Data

Sydney Christchurch Auckland Papeete Santiago Punta Arenas Buenos Aires Johannesburg Perth London Moscow South Pole Back Track Create Flight Plan

To create a Flight Plan, enter values into the fields above or click one of the blue buttons for the corresponding Airport. As soon as 2 locations are entered, the Flight Plan will be computed and displayed here. A change in any Field immediately updates the Flight Plan and the Paths on the Flat Earth Map and the Globe Earth Map.

To create Flight Plans for succeeding Airports you can simply press any blue Airport button for the next destination. The current destination Dest becomes the new origin Orig and the choosen Airport becomes the new destinantion Dest.

See Abbreviations for a description of the fields.

  • The blue line (Way Points) connects the way points calculated with the flat earth model.
  • The red line (Navigation) shows the path an airplane would trace if it follows the headings and leg distances of the flight plan. The short red lines show the direction to local geographic north.
  • The green line (Great Circle) shows the shortest path on the globe between the departure and destination airport, as flown in real life.

Note, that the headings, as calculated with the flat earth model, applied on the real world (the globe) would lead to complete wrong flight paths, especially on the southern hemisphere. So not only do the distances not match between flat earth and globe, but also the navigation (headings) can not be applied to get to the target.

Great stuff!

Could you also add Qantas QF 27 Sydney to Santiago please?

good work sir :)

Some more suggestions?

Walter, I had a lot of fun doing calculations with this today. Did an around the world in the southern hemisphere test. GRU to JNB to SYD to SCL and back to GRU. Spherical Miles (hrs) are: 4627 (8:46) 6859 (12:46) 7054 (13:07) 1627 (3:25) for a total of 20167 miles in 38.07 hrs = 530 mph
Flat Miles are: 9626 14576 15956 3512 for a total of 43670 miles. If this could be covered in the spherical time of 38.07 hrs the flight speed would need to be 43670/38.07 = 1147 mph
For the spherical calcs I found it easiest to enter the flights in FlightMemory.com with the airport symbols and save the web page with the tabular results as an html file, and then I used OpenFlights.org where I imported the html file which generated a nice map of the flights. From there it was easy to click on the points on the map and select to get the latitude and longitude for the airports, which I then used as input into your calculator.
I also found oneworld.com useful where I was able to find the airports for the around the world southern hemisphere route that I chose. Thanks for creating this flat earth flight planner calculator. Very nice.

great job walter. may I suggest adding a preset for auckland-buenos aires and sydney-johannesburg?

6Priyadi 9/9/2017 | 15:25

Oh, and auckland-santiago please.

Hi Walter,

Perhaps a preset for Punta Arenas to Perth. SCCI-YPPH

http://www.gcmap.com/mapui?P=scci-ypph

Additionally, if possible the plan from Christchurch to Punta Arenas via the South Pole.

NZCH - NZSP - SCCI

http://www.gcmap.com/mapui?P=nzch-nzsp-scci

This was the route taken by Transpolar08 when it set the world record for a transpolar circumnavigation.

Excellent work Walter, well done.

9Wolfie6020 9/11/2017 | 01:54

Fabulous Walter.

The route YPPH to SCCI is quite revealing - on a Globe it goes past the South Pole and under 6000 Nautical miles.

Initial Heading is almost due South

On a Flat Earth it goes past the North Pole and is 15,800 Nautical miles with an initial Northerly heading.

I will make a video about this and showing what the FMS in the aircraft displays for distance and the direction between the airports.
