Johnny Harris I'm a physicist, he's wrong. Airliners will rotate its pitch precisely 1 degree down per 70 miles. Or about every 8 minutes. This is how much gravity changes direction as well if you fly around the earth. They must match. Now that requires such a slight adjustment of the tail elevator that you cannot detect it. But it IS VERY slightly different than if the world was actually flat. The pilot does this by maintaining his assigned altitude, since the altimeter is a barometer and measures air pressure to determine altitude. The autopilot does the same thing. So when you maintain altitude in flight over the earth, you automatically rotate the nose down 1 degree per 70 miles, or per 8 minutes, which is 480 seconds, or 1/480th of a degree per second.

@genshotessaiga1657 You're a complete idiot.

Things don't "tilt" automatically, they have to tilt themselves. Gravity pulls the plane down, not its nose.
2
Not true. But the adjustment is VERY tiny.

You are a complete moron if you think the level experiment was valid in any way. Of course the plane angles down, but at exactly the amount needed to conform to the curvature of the earth, which keeps the plane level/perpendicular over the line to the center of the earth at all times. I'm a physicist and you're uneducated. When morons try to observe things, they make stupid mistakes of reasoning. Morons cannot do experiments that are valid.

@Charles H Geis IV No, no, no, you can't see it with a level because gravity is ALSO continuously changing direction to match the elevator adjustment, which is in the fractions of a millimeter. Anyway, planes fly slightly nose up, the down adjustment is extremely tiny.

@dennisseeker36 No, you're wrong. I'm a physicist and a pilot. You do it automatically when you maintain assigned altitude. Yes, you have up and downdrafts, but the AVERAGE downward elevator correction is MINUTE!! No, moron, the world is globe and the sun is 93 million miles away and is 860,000 miles in diameter. Why are you a dufus who can't pay attention and who jumps to conclusions?

@briananderson1246 Yup. If you horizontally compress a pic of the ocean horizon you'll see it is slightly convex.

@icookie2574 You're a fool, I'm a glober, moron.
1
@flookd5516 Yup.
1
@TR Labs You're too confused to realize that I'm a glober!
1
@spiritualricardo1265 You can.

@lcdennis4 You don't understand physics.

Amanush Azad Parallax did it too close to the water and was confused by refraction. When Wallace did it he did it with flags 8 feet tall and avoided refraction and got the right answer. The middle flag showed to be taller than the ones at either end, proving the curve.

@troyadamson8618 Didn't use one.
1
@B737FLY Oh yes it does. A plane that flies the curve of the earth has to match that curve. The adjustment is imperceptible without precision recording devices. That's one degree per seventy miles, man, or 100th of a degree continuous.

@WoRldLoveNow There are plenty. But the really pretty ones unmarred by clouds are composites. You can get a full picture from Himawari 8 every ten minutes.
1
@WoRldLoveNow Bullshit. It's a globe.
1
@flyguychris8434 Yup.
1
@Charles H Geis IV No! Untrue. The tiny amount the elevator is adjusted down is UNNOTICEABLE because it's too tiny. 1/480th of a degree, man!!
1
@dennisseeker36 Yes, I'm a physicist AND a pilot. You're mistaking me for a flat-earther because YOU don't understand the globe!!!
1
@briananderson1246 It's LEVEL, but that MEANS the level line curves around the earth.
1
Trebuchet No, I'm a physicist AND a pilot, and you are mistaking me for a flat-earther because YOU don't understand the globe.
1
@spiritualricardo1265 Yes.
1
@lcdennis4 No, you're a pilot who doesn't understand the physics your life depends on.
1
Amanush Azad "Parallax" made a mistake due to refraction, Wallace re-did it properly and proved the curve.
1
@ModelLights No, it really is true, and yes, it would be lost in all the other larger pitch change. But it is still real and would show up on fine instruments.
1
@B737FLY Actually it has to. A plane flying 6000 miles alters its pitch 90 degrees. That HAS to come from some action DIFFERENT than if the world was flat.
1
@WoRldLoveNow Himawari 8 weather satellite makes a new picture every ten minutes. Go look.
1
@flyguychris8434 Not only that, but the gravity vector is changing to match the pitch change, even if you're flying slightly nose up, as most planes do.

@spiritualricardo1265 Take a tube shaped like a U and fill it most of the way with colored water. The two arms of the U are a water level. Look out over the ocean from a higher vantage point than the mean sea level. The horizon will always be lower than the level in the tubes. You can even determine the size of the earth this way with a little math. This would NOT be possible on a flat earth. On a flat earth the level line and the horizon would appear to converge, no matter how high you were.

@WoRldLoveNow ALL of them. CGI is only used in movies and video games.

@jonm2416 Nobody YOU know if you hang out with morons.
1
@spiritualricardo1265 You couldn't understand what I said, and you want me to prove it to you?
1
@JH-zl9ll No, he's right.
1
@julianmcculloch3235 No.
1
You don't understand gravity, and a level won't work that way, it stays level all the way around the earth because gravity changes direction as you move around the earth. And so does the level in a plane.
1
J Calhoun Actually most planes fly slightly nose up, but whatever level the level indicates will be level all the way around the earth.
