A simple datapack that makes the air pressure curve in the overworld far more accurate and realistic, but adjusted to a 1/16 scale.
At this scale, mount everest would have a height of 550 blocks, while default minecraft mountains are nowhere close to this, the scale still seems to match minecrafts terrain decently well.
One small caveat is that the curve is based on real life air density, not pressure. This is due the fact that wings and propellers generate lift and thrust based on the density of the fluid they are in, not pressure. Bouyancy is a slightly different matter, but it is heavily dependent on density aswell. Thus, using density makes it more realistic.
Space begins at Y6250, which is the karman line scaled down.
