And NO IT IS NOT POSSIBLE TO FLY A GREAT CIRCLE ON A DISC
Why not? Pilots chart great circle routes onto flat maps all the time.
Again no idea about how navigation works. The "flat chart" you are refering to is a gnomoic chart. It maintains shape and size, but requries you to curve the lines of longitude. Now on a mercador chart a great circle is curved, but those are almost usless in anything but land nav, or big maps for elemetry kids. Go look up what a great circle is on wiki or something for @#$* sake. You might actually understand how completly stupid every argument you've thrown out about Great circles and rhumb lines has been.
airwingmarine... I initially was pretty upset with my first few postings with Tom Bishop, but once I learned that he's speaking a slightly different language than I am, things got better.
What he means is... it's possible to fly 'great circle-like' routes on a flat earth. Regarding whether a "great circle-like" route is shorter than the straight line route on a flat earth, I believe Tom Bishop will reply that it's part of the conspiracy.
Yea... there may be an approach us RE'ers can take that would require ever more and more people be brought into the conspiracy to account for all these discrepancies, like, in this case, fuel efficiency as if I allow the FE'ers to have GPS makers and pilots be in on the conspiracy then they can't explain the vastly different fuel consumption needed to fly a longer 'great circle-like' route on a flat earth to get to their final destination. Seems like the conspiracy would require planes with larger than is generally known fuel tanks on them or mid-air refueling, or vastly better fuel efficiency than is generally known to accomplish this. But... for the time being... I'm paying more attention to the strange optics and astronomy that FE'ers believe in and hope someone else with actual flight experience may try going in this direction.
At the end of the day though, I doubt us RE'ers showing the FE'ers that their conspiracy needs to be 10x or even 100x the size they think it is will be persuasive. So... IMHO, this is a dead end.
