What is the flight times point?
Flight times don't seem to line up with distances assuming a round earth. Specifically to south america from the old world.
Would have to see the math used. As a side note, I'm a pilot and accurate distance is critical to safe flights.
Planes measure available safe flight distance (great circle distance) based on consumption per hour. To know the duration, you have to know your speed and distance. You then use this to calculate the minimum required fuel plus FAA mandatory reserves. This in turn effects weight.
Carrying extra weight in fuel means wasted money on the weight (as it changes your angle of attack). If anything odd were going on here, it would require all pilots and airlines be involved in a conspiracy.
I'm definitely no expert on fuel usage requirements or flight times between the old world and south america. Basically that particular item stuck out to me in a video I watched a cpl years ago as them having some valid points. To summerize they were basically stating that the flight times between europe and africa to south america were too long to foot with flight times from them to north america. It was several years ago, so I don't remember specifics, but do remember thinking, "that's very weird if true". Either way it wasn't enough to convince me the world is indeed flat.
