They work the same in both situations. It’s just harder to notice curvature of the horizon, even at high altitude (plane) due to the massive distances involved. At very high altitudes it becomes quite clear that the earth is round, it’s simple observation.
the highest we can launch a hot air balloon is about 130,000 feet and it still flat horizon , and the horizon levels up to your eye - imposible on ball earth.
And the claim you cant see the curve of the earth because the earth is too big and then claim you can see ships going over the curve of the earth from 6 feet high - its a pretty hypocritical belief - but most man made religions rejoice in that kinda thing.
