Since this is all "known" and "proven" (your words), please provide this proof. Provide evidence that:
- GPS predicted distances are accurate
- Round Earth Latitude and Longitude are accurate
- Aircraft cruise speeds are measured in a way that does not use a Round Earth coordinate system
If you are making any of these claims, it is your burden to back up your argument and demonstrate it.
The evidence for TomInAustin's 1st claim is a logical argument. If GPS predicted distances are not accurate, then how can it be that GPS-based navigational systems work for millions of people on a daily basis? Are you asserting that they
don't work? Or that they
do work, but are somehow
still not accurate? I really don't know what you're getting at with this. His first claim is definitely valid.
Actually, his second claim has nothing to do with what you are asking us to prove. It
is true that aircraft flight times are recorded daily. You can check them out online - just google it. We can assume they are true because, even disregarding the fact that here, too, millions of people experience those flight times daily,
how could airlines not know how long their flights take? They have schedules, and if the times were actually inaccurate, there would be delays
on literally every flight. Are you going to assert that this is the case? Or are you claiming that even if airlines don't know their own flight times, they somehow still manage to plan everything and be on time in most cases? His second claim, too, is absolutely correct.
And then there's the thing with the cruise speeds. See, you've had 3DGeek, who happens to be a professional and an expert on the topic, explain to you exactly how it is measured and why it is measured as it is in the other thread. I'm sure you remember it - unless you decided to ignore it and walk away from the thread as soon as you started losing, just like you did on my last thread about the magnetic field - TWICE, I might say.
As a matter of fact, 3DGeek also stated why even if cruise speeds are extremely far off,
it doesn't matter at all. I'm just going to quote him:
So his ONLY remaining straw to clutch at - his lifeline - is that the speeds that are claimed for these aircraft are wildly incorrect.
BUT - the coup-de-grace is this: If the speed for the 747 is wildly different than the manufacturers (pilots, control towers, airlines) claim - then IT DOESN'T MATTER!!! If all of the 747's are 50% faster - then all of the distances we have are incorrect by the same ratio. AND THAT DOESN'T CHANGE THE FACT THAT THE INTERNAL ANGLES OF THE QUADRILATERALS DON'T ADD UP.
Which brings us to the conclusion that the first claim ("1. GPS is a proven technology that in some cases, is accurate to centimeters and at worst 10 to 15 meters") is true, the second claim ("2. Flight times between destinations are recorded daily [and are accurate enough]") is also true, and the third claim ("3. Aircraft cruise speeds are known and are filed with flight plans") doesn't even need to be true in order for TomInAustin's question being a valid one. See,
there's no point in having a designated week for discussing a specific topic if all you're going to do is deny stuff a schoolboy can prove within ten minutes. Now, would you please be kind enough as to
answer the question this whole thread is about, instead of dodging it like a coward who has no arguments left except for "boo hoo we don't know the distance from NY to Paris, and what's more, you'll NEVER EVER EVER be able to find out heheh!!!!!"
Here is my first question. Using the following airline data, how could a flat map possibly allow these numbers?
Origin Dest Miles
Sydney Santiago 7125
Santiago Johannesburg 5724
