Now who is ignoring what is presented in favour of predetermined beliefs? For a huge amount of reasons (and by the way I covered headwinds, traffic and weather conditions, if you bothered to read, not only this post but the threads the links I gave you, came from) you cannot use flight times to calculate earth's shape. That is a fact.
You will need to come up with something else to prove earth's shape.
Slightly off topic, but would you be interested in an alcoholic tomato drink?
You have provided some information in this post, but your conclusion is disputed. Your reasoning ability might prevent you from calculating things with this many variables, and that is ok, it isnt really relevant to your job as a pilot. You just make sure your instruments give the correct readings at the correct times, and follow your checklists, you dont truly need to understand what you are looking at or where you are going (aside from watching for solid objects in the air)
Too many times on this forum is the conclusion "You cannot use X to determine the shape of the earth"
My rewording: " we, as layman, do not understand how to use X to determine the shape of the earth"
All of your babble aside, everything you reference involves adding to the total flight time. I am focusing on the minimum possible flight time.
If a plane flies from hawaii to sydney, and it takes 12 hours to reach there, then we can determine a maximum possible distance. If any of your factors are applied, they would decrease the maximum possible distance.
As your FE theories all involve the distance between vastly (400%) further then the real distances, then in a best case scenario it would still take much much longer to arrive. And if any of the stuff you babble about occurs, then it will take even longer.
My calculations stand. At a maximum speed of 1500 km/hr in 12 hours you could fly 18,000km at maximum, if none of the stuff you mention occurs. Indirect flightpatchs add distance, weather adds distance, ..............etc ad naseum
you dont like 1500 km,hr? Maybe there are magical 500 mph winds down there? Call it 2000 km/hr 24,000 km max then. Still doesnt come near to matching your artwork
