Flat Earth Theory / Aviation and the WGS84 model
« on: February 07, 2019, 10:59:50 PM »
Hi Guys, I am a newbie so hopefully you will go easy on me.
As a professional pilot, we have to navigate up in the sky and rely on GPS as our primary navigation tool.
The units take thier signals from both SBAS (Satellite based navigation system) and GBAS (Ground based navigation system)
Without going too deep, If the earth was actually flat, then if one were to fly from a point on the equator, lets say at 053n0000w which is just east of Accra International airport and exactly on a meridian of longitude.
If you were to fly 500nm north on the meridian, then turn left and fly 500nm west on a constant heading then 500nm south and finally 500nm east.
Were the flat earth theory to hold any water, then the aircraft would end up exactly back where it started.
In real life, this simply isnt the case.
I note there are many references in the respective arguments that reference aviation so I am happy to try to assist if possible.
