Horizon Dip Measurements
The horizon dip measurement is the angle between the horizontal (the line perpendicular to the vertical at a specific point) and the apparent horizon.
On a globe, we would expect this angle to increase with increasing altitude, because the horizon would drop away with the curve.
On a flat earth, we would expect the horizon to always "rise to eye level".
