How would a plane stay on course if the Earth was a ball? It couldn't. Gyroscope being functional and used in aircraft travel proves the Earth is flat. It's that easy.
Did you ever run a "actual gyro" from plane on your table open? :) Just for curiosity? No?
Guys, you continue to show yourself as ignorant parrots. Why?
You are just stupid parrot, nothing more. Actual gyro avia horizon does not use gyroscope to show something. It uses gyro as damper for pendulum. Avia horizon task is to stay tangential to Earth surface using gravitaion and sometimes Earth magnetic field in addition as a base, not gyroscope.

Do you have patience to look at steady avia horizon started in wrong position settling to correct one for 10 minutes? Or you just another TikTok generation kid without an ability to understand so long video?
Aviation horizons self-stabilising within few minutes to show what it made for - horizon, not some senseless "orientation in 3D".
It does not "maintain orientation in 3D", because any aviation gyro horizon is made for completely another task.
Laser "gyros" (AKA Sagnac interferometers) are another beasts, but they do not "maintain position in 3D" too. Their output signal is speed of rotation, not position.
Meanwhile laser gyro is one of the cheapest high quality instrument that will show you Earth rotation and curvature you could make in garage by yourself. I think it is also below $100 thing. You will need 1km of raw fiber (~$20 on aliexpress), 4-way 2x2 fiber splitter (~$7 on aliexpress), laser/photodiode combo with fiber connectors from two-eyed SPF or fiber converter (free from garbage bin) or separate laser and diode with fiber connectors (~$20), battery and resistor to power laser(<$1), handful of resistors with OPamp (<$2) and any multimeter (f.e. DT-830 for <$10). All you need is to connect everything and tune your gyro to lowest possible photodiode signal. Any rotation of the fiber coil will cause signal grow. Including rotation of Eath.

About Airey - he assumed that there exists aether presumed to be a substance where electromagnetic waves propagate. Also he assumed that medium dragging aether, depending on it's density. That effect was presumed as a cause of abberation effect on stars. So, he thought that is he will observe star through more dense medium, than, abberation will be larger. But he does not observe that. and that's all. That does not mean that Earth is not moving. That means that there are no aether, or it is dragged equally by any matter.
thanks for posting dum video, it shows that your "artificial gyro horizon" has nothing to do with the actual horizon, it just shows level, and since the demonstration was done on a completely flat table , its not proving that the device actually registers a drop due to earth curve during flight, it just shows it has the ability to find level. So as you said be4 "Why all ball-earthers are absolutely unable to do anything except copy-pasting dumb links and phrases? Really, ball-earthers who pose themselves as "critical thinkers" is the most incurious characters I ever met. I never saw a single ball-earther who posted his own thoughts, observations and replicateable experiment results. No one who did something himself. Only copypasting of stupid youtube videos by ball earth shills made by swindlers for views, likes and ads money."
And as for "light gyros" they register diffraction of light with the medium, not with the earth, but of course youll believe anything your told, including double think. These interferometer are used in commercial airplanes at 30k feet are in there own enclosed environment - what do you think light from the sun bounces differently depending on how much it spun and then goes into the interferometer?: Interferometry has nothing to do with the shape of the ground, so just Shut u and do yourself a flavour and just go away with your rage posting complete nonsense of how youve been fooled into thinking the earth is a spinning ball, its not.
