Here is a flight instructor explaining the concept, if you'd like to learn something.

That was the
wrong video. (After I posted this, the video above was changed in the post so now it's a different one.)
Here is a commercial pilot
and flight instructor, explaining how gyros (Artificial Horizon) work in aircraft:
.
Artificial Horizon Experiments1. Prove Artificial Horizon Instruments have self-correcting mechanism.
2. Prove the Instrument will always correct to level.
3. The correction rate is faster than 1 degree in 8 minutes. (This is faster than 450 mph takes to traverse 1 degree of curvature.)
4. Debunks the flat-earth claims that an Artificial Horizon is evidence of a "flat" earth.
.
.
At the end of this video I address several points that I see often in comments by Flat Earthers.
The experiments prove that the instrument "is capable" of remaining level while flying across curve.
That fully debunks the Flat Earth claims that the Artificial Horizon is evidence of a Flat Earth.
This instrument can easily correct for curvature and therefore will show level as you fly around a curved Earth.
The errors you see in this video will never occur in a normal flight...World map WGS84 basis for GPS, international flights, major international airports for use by aircraft.Incredibly accurate world map, with tolerance within 2 centimeters..
