Airplane pilots don’t adjust course for the curve

If the Earth were truly a sphere 25,000 miles in circumference, airplane pilots would have to constantly correct their altitudes downwards so as to not fly straight off into outer space.

This is a mistake, it is not a proof the earth is flat. Airline pilots have an altimeter which they use to keep the plane at a fixed altitude [distance from the earth] and also they aim at the horizon. So if the earth is a globe and you keep your airplane at a fixed distance from the earth then automatically you are correcting your course to remain at a fixed distance from the earth, in other words you are going around the curve of the earth. Also by aiming at the horizon that will cause you to constantly follow the curve of the earth.

So airline pilots already have two perfectly good systems in place that ensure they will follow the curve of the earth if it is a globe and these systems will work equally well to enable them to stay a fixed distance from a flat plane if the earth is flat.

The conclusion is airline pilots do adjust for the curve, if it exists, so this does not prove or disprove the flat earth or the globe earth.

    I wrote this to Dubay about his 2777ft drop per minute claim.

    The problem is that you’re not doing the correct math equation.You’re taking the drop in 500 miles, 166,667ft and dividing by 60 minutes, or total flight time, to get the correct but ridiculous number of 2,777ft per minute drop.

    To simplify, use 600 miles per hour, divide by 60 minutes means you’re flying 10 miles per minute, 10x10x8/12=67ft roughly. So, which is it? Is the plane dropping 2,777ft per minute or 67ft per minute? Neither.

    If the plane is flying 10 miles per minute that means it’s going 1 mile in 6 seconds. Is an 8 inch drop in 6 seconds the correct answer? That’s really not much of a drop but that’s still not correct.

    A 747 is about 250ft in length. 250ft/5280=.0473 of a mile. The plane is .0473 of a mile long.

    .0473x.0473×8=.017 of an inch. In the planes length the earth drops .017 of an inch. That’s just a little over 1/64th of an inch.

    Theoretically an airplane could maintain a flight altitude just a little over 1/64th of an inch out of level and circumnavigate the entire globe.

    I say theoretically because there are so many forces involved the plane’s computer or the pilot are always making corrections.

    Hopefully facts will prevail in this silly flat earth craze!

      Hi Keven

      Yes. This whole idea that if the earth was a globe planes would fly off into space because they are not putting their nose down is ridiculous.

      In the olden days the pilot was always aiming at the horizon, that would automatically correct for the globe, and he was keeping at a fixed height above the earth with his altimeter. So he was constantly correcting for the globe by constantly aiming at the horizon and keeping the plane at a constant height above the ground. So now the computers are doing the same thing. Constantly correcting.

      So it is just a crazy idea. There’s no need to do the maths actually. Because either of these things would automatically correct for the globe. If you stay at a constant height above the surface of the earth then no matter what shape the earth is you will follow that shape. And if you point at the horizon also that will keep you following the contour of the earth below you. No matter what shape it is…

          Lee, maybe you can prove through scientific facts how the earth is flat?
          As far as an answer to your question, the reason we know the earth is round is:
          At a very basic level, we can see the Earth’s curvature through satellites that have been launched into space. Additionally, through the use of high-powered telescopes, it is possible to examine planets both in our solar system and beyond, and all of them are spherical in shape.

          There is a very deep, fundamental reason why the Earth is round: the force of gravity depends upon the distance between two interacting objects, and the only three-dimensional object you can make with a single distance is a sphere. We can measure the behavior of gravity in the laboratory with a variety of highly sensitive experiments. Each of these experiments shows that the force of gravity depends only on the mass of the two objects and the distance between them. If, on the other hand, you wanted to form a flattened object using gravity alone, the force of gravity would have to depend upon two, perpendicular distances in two perpendicular directions.

            Hi Rob

            Yes. You have given two of the basic ‘proofs’ that the earth is a globe.

            • Photos from space
            • As above so below

            That is good if you believe in the photos from space. I must note that from a couple of hundred miles up [low earth orbit satellites, space station, etc, you can not see the curve of the earth.] If you take a ball and scale it to the 8,000 mile diameter of the earth and come up a couple of hundred miles you will see that is not sufficient to tell if the earth is flat or a globe. But you could see the whole globe from satellites in geosynchronous orbit, if you believe there are satellites in geosynchronous orbit.

            And your other point, because the moon is a globe, the sun is a globe, Mars is a globe, etc, then Earth must be a globe also. That is not proof, it is a deduction. Still possible that Earth may be different from the globes we see above our heads.

            As far as your claim that there are scientific experiments demonstrating gravity, the attraction between two objects. I have never heard of any such successful experiment. The scientific opinion is that no such experiment is possible on earth because any small gravitational pull that may be generated by your ‘heavy objects’ will be completely overwhelmed by the huge gravitational pull of the earth we stand on. So there is no experiment showing the working of gravity possible on the earth, at least not as far as I am aware.

      Pilots aim at the horizon, so by doing this, if the earth is curved, they are automatically adjusting for the curve, similarly computers they use the gyroscope and the altimeter, to keep the plane at a fixed height above the earth, which will automatically adjust for the curve if there is one.

    pilots fly great circles which lines of longitude are not concentric like the lines of latitude. the roads across the prairies do indeed require correction periodically

    Tesla said that gravity does not exist and I believe him. So If I am standing facing the rising sun and I jump towards the sun, Why can’t I jump further towards the sun than I could away from the sun

    • Derek Jacobs

      You are weighed down by a “blanket” of particles above your head. While it is easy to jump and break through some of those particles (like diving into water), it takes great force to go up or down further. Blanket Theory.

  4. Earth Globe

    Gravity is a thing…
    Centuries of scientists and researchers developing and proving the theory of gravity yet in the 21st century, people think all this hard evidence is false. 21st century, I’m gonna lose it with flat-ass earthers and people who think they’re suddenly Icarus and can jump towards the sun.
