Gyroscope on a plane
« on: March 18, 2018, 01:16:06 PM »
Can anyone take a gyroscope on a plane and keep it spinning on their next trip across the US or to another country?

If it shifts according to Earth's curvature, that's an issue. If it stays the same the whole time, that's an issue too. Magazine issue

Artificial horizon is gyroscopic device and it has self-correction faster than the angle changes when airplane reaches new verticals along the path.

All modern aircraft since the launch of the Boeing 747 use an inertial reference platform composed of 3 laser gyroscopes. The GPS on newer aircraft supplements that platform and so aircraft operations are independent of that system. It does add dramatically to the accuracy but is not essential, whereas the inertial platform is essential.

Actually, the surface of the Earth itself is moving as fast as an airplane, and it's easier to keep a large gyroscope undisturbed on the ground than in a plane.

A french physicist named Léon Foucault already did it 166 years ago.

You need a very well balanced gyroscope for this.
If it is not properly balanced the drift due to the imbalance can be more significant than the drift due to Earth's rotation or change in position.
So I would recommend one which can be calibrated.
Set it up in one location, leave it fixed, monitoring how much it drifts and calibrate it so it doesn't drift. Then carefully transport it to another location and see if it drifts there.

Why would this be an issue? because this is what it should do if the earth is flat, which it is.

Basically this has an internal pendulum that the gyro self-corrects to. This is proof, these type of gyroscopes will never tell you anything of value in regards to the earths shape.  A true 100% mechanical gyroscope would have to be used, and of course it would show with 0 doubt the earth is flat.

They will tell you that you don't have to "dip the nose down" when flying along the great circle.

And when you add the description of altimeter, it is completey clear that there is no recalculation needed to follow the Earth's curve.
You would need calculation not to, but planes are limited to atmosphere.

Nope. It would either be unable to tell the difference between a flat Earth and round Earth, or it would show a round Earth, just like everything that can distinguish between a flat or round Earth does.

P.S. Unless the plane follows a perfectly straight course without changing attitude, it should move if Earth is flat.

The technology does not exist to create to create a gyroscope with that much precision that you could take onto a plane

This looks pretty reliable to me:
